Clouds, cool and wet weather to linger in Montreal

A stubborn weather pattern is resulting in dismal weather here in southern Quebec, while producing rounds of severe thunderstorms across the central United States. The damage above occurred with a strong tornado in St. Louis, Missouri on Friday. The storm resulted in significant damage and sadly the loss of 5 lives. The death toll stands at 33 from the weekend storms. (CBS)

Montreal is in the midst of a long stretch of rather dismal weather. It is a very chilly morning in the city, with 8C (48F) here in Ile Perrot. The temperature will not budge today, under persistent clouds and northerly winds, we may see 10C (50F) if we are lucky. Expect a few showers as well.

The forecast does not look good the balance of the week, with a persistent northerly flow of cool, moist air expected. Look for clouds and showers right into next weekend, along with well-below normal temperatures. Daytime highs will rage in the low to middle teens, with overnight lows from 7C to 10C (45-50F). Warm weather is expected to return to southern Quebec for the last week of May.

As far as precipitation is concerned, another 10-20mm of rain is possible by the weekend. I measured 33.2mm here on Ile Perrot since Friday afternoon. The bulk of that occurred during thunderstorms Saturday morning. May is definitely been wet, with 77mm falling as of Sunday at Trudeau Airport, with 69.2mm here on Ile Perrot. 

The culprit has been a strong upper level low slowly drifting from the central Great Lakes Friday into northern New England on Monday morning. The result has been waves of rain and much colder temperatures. In advance of the low, we managed a muggy 29C (85F) on Friday before strong thunderstorms arrived on Saturday. Those storms produced mostly heavy rain here in the Montreal region, with plenty of lightning. Other parts of southern Quebec reported hail and there was flash flooding in Sherbrooke after 50-70mm of rain fell in just a few hours.

South of Montreal near Howick, there was report of a weak tornado around 7:30pm Saturday evening, There was no damage observed, and Environment Canada is investigating to determine the strength of the storm. The strong storms also produced widespread severe weather in Vermont, with flash flooding, downed trees and large hail.

The same weather setup is delivering rounds of severe weather across the central portion of the United States. The weekend death toll stands at 33 from persistent and long lasting tornadoes across several states. The hardest hit region stretched from Missouri to Kentucky. A powerful storm killed 5 in St. Louis on Friday, while London, Kentucky was leveled on Saturday. In Kentucky, 19 deaths have been reported so far, with scores of injuries and widespread damage.

Another round of strong storms is forecast on Monday for parts of the southern plains from Colorado and Kansas into Texas and Oklahoma.

Thunderstorms - cooler weather on tap for Montreal

Day turns to night as a 3000 hectare wildfire burns out of control south of Wendigo Beach in Manitoba on Wednesday. Unseasonably hot weather has fuelled the massive wildfire near Lac Du Bonnet in the eastern part of the province. Some relief is sight as rain and much colder weather arrives late this week. (Photo: Manitoba Hydro)

The warm weather will continue in Montreal for a few more days, with a noticeable increase in humidity levels as we head into Friday. A large upper level low spinning across the northern plain states, will move across the Great Lakes and slowly into Quebec this long Victoria Day holiday weekend.

In advance of the low, a warm southerly fetch of moist air form the Gulf of Mexico will push high temperatures once again into the upper 20s across southern Quebec. On Wednesday, Quebec and New Brunswick were the warmest spots in Canada. Montreal reached 27.4C (82F), the normal high for mid May should be around 20C (68F). Other parts of the region were even warmer, close to 30C. Roberval in central Quebec reached 31C (88F). In New Brunswick, six record highs were established for the date, including 31.8C (89F) at Edmunston.

The warmer more humid air on Friday will lead to the development of widespread afternoon showers and thunderstorms, with some locations receiving as much as 25mm (1 inch) of rain. The moisture will be welcome.

The aforementioned upper level low will result in much colder weather arriving in Montreal by Sunday. After the thunderstorms and warm weather on Friday, Saturday will be a transition day, with rain and windy conditions expected. Highs in the 20s, will drop by Sunday and Monday into the middle teens along with gusty west and northwest winds.

Manitoba Wildfires

The unseasonable heatwave that has been impacting southern Manitoba and Saskatchewan has lead to significant and early start to the wildfire season. The Lac Du Bonnet fire in eastern Manitoba has reached 3000 hectares, one of 24 burning in that province. The fire has resulted in the evacuation of over 1000 residents, destruction of property and sadly two fatalities. The fire has been fuelled by days of record-breaking heat, reaching 37C (100F) at times. Dry weather and strong winds have moved the fires along quickly. Relief is in sight as much colder weather and rain are forecast over the next 48 hours. Unfortunately strong winds are expected as well, gusting up to 80km/h.

Summery weather week ahead for Montreal

Sunshine returned to Montreal on Sunday after 24mm of rain fell Friday and Saturday in the city. The warming temperatures and precipitation have finally allowed the trees to begin leafing out in southwestern Quebec. Unfortunately along with that comes pollen and seasonal allergies.

Skies are clearing Monday morning across southern Quebec, as a weak warm front lifts north of the St. Lawrence Valley. This will set the stage for a very warm week ahead, with temperatures reaching summery levels for the first time this season.

We can expect mostly dry weather through Thursday, but we can't rule out an isolated sprinkle or rumble of thunder, especially mid week. The best change should remain southwest of Montreal over upstate New York and eastern Ontario.

High temperatures will start in the lower 20s Monday, 21C (70F) here in Montreal, and gradually rise into the upper 20's (lower 80s). Overnight lows will remain very mild for early May, in the middle teens.

Unfortunately there will be some changes in the weather by the long Victoria Day weekend. Low pressure will move across the Great Lakes by Friday, with a more humid fetch of air moving northeast from the Gulf of Mexico. This will likely lead to some decent showers and thunderstorms by Friday, persisting into the weekend.

By Saturday, we can also expect some cooler air to move into Montreal on the back side of the aforementioned low pressure, as it moves into central Québec. Temperatures will lower into the upper teens for daytime highs by Sunday.

HEATWAVE

Central portions of the United States from the high plains into extreme southern Manitoba are experiencing an unprecedented early season heatwave. On Sunday, the temperature reached 37.8C (100.4F) at Emerson and Dominion City, Manitoba, shattering the previous record of 30.9C (87F) set just last year. The normal high for early May is only 20C (68F). Another indication that we are seeing some significant early season warming in Canada in recent years. This was one of 9 new temperature records established in the province. Southern Saskatchewan also reported record breaking heat. Heat warnings are in effect again Monday, with another round of mid to upper 30s forecast. Winnipeg is expecting a high of 35C (95F) on Monday.

Flood concerns on the rise across southern Quebec

Several municipalities in southwestern Quebec are monitoring area rives for potential spring flooding. At this time, only minor impacts are expected. If you live in a flood-prone area, remain vigilant. (Valley Weather Photo)

Some rivers in southwestern Quebec have reached minor flood stage, but the threat is relatively low at the time, with any flooding confined to the immediate shoreline and low-lying areas.

Several waterways in the region are being observed for minor flooding as runoff from the upper Ottawa Valley makes it's way into southwestern Quebec. They include the Ottawa, Rigaud, des Milles Iles and des Prairies Rivers.The good news is that it has been a relatively dry spring, void of any big storms. Rain is forecast Friday and Saturday, but the heaviest precipitation should remain over New England.

At this time several municipalities, including Pierrefonds, Senneville and Ile Bizard have started to prepare in the event of flooding. This includes preparing sandbags, pumps, flood gates and temporary muscle walls. The Village of Senneville has moved into Intervention 2 mode. They have made sandbags available to residents and have established a call centre.

Most computer models have the heaviest rain from this weekend's storm remaining over New England. The GFS is forecasting 18mm for Montreal by 1pm Saturday, with more over the Townships. (Ventusky)

In the province, 12 waterways are under surveillance by Sécurité Publique Québec, with 10 additional waterways in minor flood stage. They include the Ottawa and Rigaud Rivers, as well as Lac des Deux Montagnes. In the latter caae, the level is now at 23.37 metres, minor flood stage is reached at 23.30 metres. In all cases, water levels are fairly stable and well below the historic spring flooding in 2017 and 2019.

Developing low pressure Friday east of the middle Atlantic will move along the eastern seaboard into Maritimes over the weekend. A chilly rain and gusty northeast winds will develop in Montreal Friday, with 10-20mm possible by late Saturday. Much heavier accumulations, in the order of 25-50mm (1-2 inches) are likely in the Eastern Townships, with amounts reaching 75mm (3 inches) over Vermont. A flood watch is in effect in southern Vermont.

The good news for our region is that the Ottawa River basin will be on the far western edge of this storm system, with very little precipitation expected in those locations. Additionally, high pressure will build into the region starting Sunday, with warm and dry weather forecast next week through Wednesday. This will allow water levels to stabilize and even lower in most cases.

Remember, if you live in areas prone to river and spring flooding, remain vigilant and listen to what local authorities and municipalities are advising. Many municipal websites have sections dedicated to spring flooding, with information and contact numbers.

Summer warmth on the horizon for Montreal

Like a mountain range in the sky, dark clouds loom on the western horizon Wednesday morning, as an upper level low over Ontario moves into southern Québec. So far most of the chilly weather and heavy rain has remained in eastern and central Ontario. (Valley Weather Photo)

I must admit, I was wrong on the chilly weather forecast so far, as temperatures this week have over performed to this point. Montreal recorded a high of 24C (76F) on Tuesday, as skies cleared from morning rain, and the bulk of the afternoon thunderstorm activity remained to our west over Ontario. An upper level low, part of a larger omega block, has been stuck over the Great Lakes all week. Areas that have been receiving rain, have received quite a bit, in the order of 50mm. Here in Montreal, close to 15mm fell, but it was less than I expected, and temperatures have been warmer.

Radar Wednesday morning showing heavy precipitation from an upper level low spinning over parts of southern Ontario. The bulk of the rain has missed Montreal so far, with only 15.4mm falling so far this month, most of that occurring in the pre-dawn hours Tuesday morning.

As I write, the clouds are playing with the sun, in advance of the low pulling across southern Quebec and dragging a cold front along. Showers, with perhaps a rumble of thunder are likely Wednesday afternoon, before precipitation ends this evening and temperatures fall.

Thursday through Saturday will be partly to mostly cloudy, but fairly dry for southern Quebec. There is a risk of a few spotty showers and temperatures will be much cooler. Morning lows Thursday will drop into the upper single digits, with highs struggling to reach 13C (55F).

The good news is that much warmer, more summer-like weather is on the immediate horizon. High pressure will slowly drift across the region starting Sunday into next week. Highs will be in the lower 20s, Sunday but warming up to 28C (83F) for Monday and Tuesday. Some much needed sunshine is expected.

First Quebec Tornado for 2025

The Northern Tornadoes Project from Western University in London, Ontario finished their survey of damage caused by severe weather on April 29. They determined that outside of straight line winds here in the Montreal region, the first tornado of the season in Quebec occurred north of the St. Lawrence Valley at Saint-Zénon. The EF-1 tornado, capable of winds of up to 165km/h, moved along a 600 metre-wide path for 6.74 kilometres. The storm flattened trees, damaged barns and tore the roof from a home. It was the third tornado reported in Canada so far during this very young severe weather season. Thankfully there have been no injuries reported.

Unsettled, chilly weather week ahead for Montreal

A Hydro-Québec team repairs significant damage to utility lines on May 1st, after last Tuesday's thunderstorms caused widespread power outages across the Montreal region. Rumbles of thunder are possible this Tuesday and Wednesday from a cold upper level low, but outside of perhaps some small hail, no severe weather is expected at this time. (Hydro-Québec Photo)

The weather will not feel like May this week as a series of frontal boundaries and an upper level low combine to bring us a chilly damp week. Monday will be mostly cloudy, but with some breaks of sun, allowing temperatures to reach into the upper teens, perhaps 20C (68F). It will likely be the best weather day of the work week. 

Clouds thicken this afternoon and showers arrive Monday night into Tuesday, along with a few rumbles of thunder. Temperatures will remain mild through Tuesday evening, dropping to 11C (52F) and perhaps reaching 21C (70F) Tuesday. By Wednesday, and upper level low over the Great Lakes will move towards Quebec City, keeping a damp, chilly airmass in place over the St. Lawrence Valley. Temperatures will drop into the lower teens for daytime highs, along with cloud cover and occasional showers. Overnight lows will be in the single digits.

The aforementioned low will slowly drift into Atlantic Canada by the weekend, but may be replaced by another area of low pressure. While the week will not be a complete washout, the weather will certainly not feel very springlike. However as we have seen in the last week or so, it does not take much sunshine to push temperatures up quickly. We can only hope those breaks of sun will be more numerous than the forecast predicts.

Strong thunderstorms cut power to thousands of Quebec homes - injure one

Lightning strikes the ground in Saint Laurent as strong afternoon thunderstorms moved across the Montreal region. An even stronger cell along a cold front produced significant damage and power outages during the evening hours. Wednesday will be the calm after the storm, with a blustery, chilly high of 12C expected. (Valley Weather Photo)

As forecast, a series of strong thunderstorms swept across southern Quebec Tuesday afternoon and evening, producing widespread damage and power outages. It was the second set of storms for the day that occurred between 7:30pm and 9pm that did the most damage. Trees and power lines were knocked down from the central portion of the Island of Montreal north into Laval and southeast including some south shore communities. The West Island and off-island communities to the west were largely spared. 

At the height of the storm, Hydro-Quebec reported nearly 150,000 customers without power. That number is down to 88,000 as of 8am Wednesday morning. This includes nearly 12,000 clients on the island of Montreal. Hydro has over 500 teams repairing the outages, but is indicating that it could take some time to restore power, as there are over 700 induvial breaks in the grid.

The storms delivered wind gusts of 87km/h at Trudeau Airport, but well over 100km/h in other parts of the region, including Laval. Several trees fell on homes and cars, and in one case critically injured a teenager in Ahuntsic, when he became pinned under a fallen tree on Grand-Allee Boulevard.

Highway 19 in Laval at the junction of Highway 440 remains closed do to fallen power lines across the road surface.

Significant damage and minor injuries were reported at the Maisonneuve Rosemont Hospital after several windows were shattered by the wind.

The first severe weather of the season also produced damage and power outages in many locations across central and eastern Ontario into upstate New York.

Here on Ile Perrot, the storms missed my location, producing only gusty winds, lightning and around 1mm of rainfall. The weather was very warm and humid on Tuesday, reaching a high of 24.3C (76F) at Trudeau Airport, with 27.1C (80F) here on Ile Perrot. We have however gone form air conditioning to heat in Montreal over the last 12 hours or so, dropping from a high of 18C (65F) at midnight down to 1C (34F) early Wednesday morning. The cold air will remain for 24 hours, with a blustery, chilly high of 12C (54F) Wednesday in Montreal.

Frost Advisory

A frost advisory is in effect through Thursday morning for most of southern Quebec, with morning lows close to the freezing point expected. Clouds will increase Thursday, with another round of showers and thunderstorms forecast by Friday, along with moderating temperatures. 

Moderate risk of strong thunderstorms Tuesday for parts of our region

ECCC map showing the risk level for thunderstorms today in southern and western Québec. (Double click for larger image. Courtesy ECCC)

Environment Canada has a portion of our region under a moderate risk for strong to severe thunderstorms on Tuesday. A warm front has lifted north of Montreal early Tuesday morning, with gusty southwest winds developing, brining in warm and humid air from the central portion of the US. High temperatures will push into the middle and in some cases upper 20s today. Humidex values will rise to near 30C for many. The forecast high for Montreal is 24C (76F), the warmest of the year so far.

This afternoon, a strong cold front will move southeast across Ontario and into Quebec this evening. A wide area of southern Ontario from Windsor to the Nation's Capital is under a moderate risk for severe thunderstorms, including large hail, strong winds and isolated tornadoes.

That risk area extends into western Quebec and the Outaouais. Here in southwestern Quebec we can expect thunderstorms this afternoon. The risk for severe storms here is minor, with the main threat being gusty winds, dangerous lightning and small hail.

The front should clear the region late this evening followed by gusty northwest winds up to 50km/h and rapidly falling temperatures down to 1C (34F).

Wednesday will partly sunny, windy and much colder, with a high of only 12C (52F).

Vote Today! The weather will be perfect in Quebec

Unlike many previous election days, the weather will be perfect on Monday to cast your vote in the 2025 Federal Election. Expect a sunny, warm day in Montreal, with a high close to 20C. (Elections Canada Photo)

Ideal weather in Montreal today to cast your vote in the Federal election.

Strong to severe thunderstorms possible Tuesday afternoon.

Unsettled weather week ahead.

You certainly can't blame the weather for not getting out to vote today, Monday, April 28, Election Day in Canada. We have had some miserable weather during voting days in the past, but such will not be the case today. Strong high pressure has moved into southern Quebec, producing a wide area of sunshine and warm temperatures. The ideal weather will stretch across much of eastern, southern and central Ontario to the west and east into portions of Atlantic Canada. 

In Montreal, look for sunshine, breezy conditions at times, and a warm high of 20C (68F).

A heavy wet snow fell for a few hours on Sunday morning in parts of southern Quebec, with over 10cm reported in Sherbrooke. By afternoon, the warm April sun had sent temperature quickly back into the teens at most locations. Sherbrooke remained chilly, with the fresh snow down, only reaching 5.5C (42F) for a high temperature. (MétéoMédia Image)

Over the weekend, strong low pressure moved across southern Quebec, producing a cold rain Saturday, and in some cases wet snow on Sunday morning. Just enough cold air filtered in behind the storm system to produce several centimetres of wet snow at higher elevations across the lower Laurentians and into the Eastern Townships. Sherbrooke reported and incredible 12cm of snow Sunday morning, falling in just a few hours.

Oddly, even a trace of snow fell at Trudeau Airport, with a Sunday morning low of 2C (36F). But, by the afternoon, the warm April sun had pushed temperature quickly up to 18.5C (66F) for a high in Montreal. Trudeau Airport measured 19.2mm of rain over the weekend, well under the rainfall warning threshold.

We have a very active weather week ahead for eastern Canada. A strong frontal boundary will produce showers and gusty thunderstorms on Tuesday afternoon. Strong southwest winds of up to 60km/h, will drive temperatures into the low and middle 20s on Tuesday. A strong cold front will arrive in the afternoon across Ontario and early evening here in Montreal. There is a chance for some severe thunderstorms for our region, with the main threat being strong winds. An isolated tornado over parts of eastern and central Ontario cannot be ruled out. Temperatures will fall significantly behind the front down into the low single digits by Wednesday morning.

More rain and thunderstorms are possible by late Thursday into next weekend.

Spring slowly arriving across southern Quebec

For the second year in a row, snow fell on the day I was removing my winter tires. Perhaps this was the last snow of the season last Wednesday, April 16, with 1cm reported at Trudeau Airport. Accumulations ranged from 1-3cm across most locations, confined mostly to grassy and cool surfaces. To date 7cm has fallen this April at Trudeau, with 58.2mm of rain. My feeling is that we are now done with the snow until next fall. (Valley Weather)  

The warm weather has been slow to arrive across Southern Quebec this Spring. The grass is slowly showing signs of growth and the buds are appearing on the trees finally. It has been the same across most of the country this April. On this Easter Monday, Montreal dropped below freezing, with scattered frost reported. Snow is falling across portions of northern Ontario around Thunder Bay and Lake Superior, as well as strong storm is expected to drop 10 to 20cm on parts of northwestern Newfoundland.

Here in Montreal, this morning and Sunday's chill were in stark contrast to the warm and dare I say humid conditions on Saturday. Many locations across the region had there warmest day of the year Saturday, with the official high reaching 20.5C (69F) at Trudeau Airport. Some South Shore locations, including Saint Anicet, surpassed the 21C (70F) mark. A windy cold front produced showers and thunderstorms, resulting in Sunday temperatures being as much as 15 degrees colder.

Sunshine will prevail Monday for Montreal, but another frontal boundary associated with low pressure over the Great Lakes, will lift across the St. Lawrence Valley this evening and into the overnight hours. Expect clouds to thicken quickly late Monday, followed by a few hours of rain. The rain will taper to showers early Tuesday morning, followed by clearing. Sunshine returns through Friday morning.

Temperatures will remain close to the long-term average this week, with highs in the middle teens (55F) and morning lows between 3C and 5C (39 to 41F). The work week will be mainly dry after Tuesday, with the next chance for rain and warmer weather arriving by next weekend.

Perfect Monday - but unsettled weather week ahead

April has always been a month of transition and extremes in southern Quebec, as the seasons battle. Ultimately spring will win  out, but it may take a couple of more weeks for that to happen this year.

High pressure will dominate the weather on Monday across southern Québec, with abundant sunshine and warm temperatures into the middle and upper teens. Enjoy today, as the balance of the week looks rather unsettled and cool.

Over the weekend, a late season coastal storm moved along the Atlantic coast, bringing snow to portions of southern and central New England. Montreal was on the extreme northern edge of the system, with clouds on Saturday, and light rain as far north as the south shore. The city remained dry. Sunday was near-perfect, with sunshine an a warm high of 15C (59F). 

April has been a rather cloudy, cool and breezy month to date. Winds have gusted over 30km/h each day, often chilly from the northeast. We have managed 484mm of rain and 6cm of snow as of Sunday. I am hopeful the snow is done for the season, but we may see a few flurries midweek.

Clouds will increase Monday night as a frontal boundary lifts into the St. Lawrence Valley. Showers are likely, and will continue into Tuesday. Temperatures will be mild for the next 24 hours. Strengthening  low pressure will lift northeast towards Quebec City by Wednesday, dragging a cold front across the region.

Look for much colder weather Wednesday and Thursday, with highs only in the single digits and lows near freezing. The front will also produce a mix of rain and snow, with any snow accumulation confined to the highest elevations, especially across the eastern Townships and Green Mountains of Vermont. In Montreal, only a few flurries or wet snow showers are possible.

By Good Friday, skies should clear for the day, along with seasonable temperatures. The good weather will not last as another system is forecast to bring rain for to begin the Easter long weekend.

Late season storm results in dozens of accidents in Montreal

Leftover ice and snow from Tuesday's storm along with cold morning lows resulted in many more accidents on Wednesday morning, including this one in Sainte-Anne-de-Bellevue. (Valley Weather)

I was one of many Montreal motorists surprised by the heavy snow and rapidly dropping temperatures that occurred during the Tuesday evening commute. A stubborn area of low pressure slowly moved along the international border, dragging down unseasonably cold air behind it, and just enough moisture for some decent afternoon snow.

The storm came in two waves. The snow early in the morning was along a cold front. That precipitation largely fell north of Montreal, with just a dusting here in the city. Meanwhile, the bulk of the moisture with the area of low pressure was across the Ottawa Valley. In Ottawa, just under 15cm of snow fell on Tuesday, accompanied by unseasonably cold temperatures and strong winds. 

As the system pulled east, it dragged any leftover moisture across the Montreal region, just in time for the afternoon commute. The snow fell heavy at times, and as temperatures dropped quickly with the loss of daytime heating, ice began to form on elevated surfaces. Gusty winds reduced visibilities in blowing snow.

Rapidly falling temperatures along with bursts of heavy snow, created ideal conditions for ice to form on elevated surfaces during the Tuesday evening commute in Montreal. The result was dozens of accidents and major delays for motorists returning home.

The result was a rash of serious accidents, including one involving at least 20 vehicles that closed the southbound lanes of Highway 13 along and just south of the bridge connecting Laval. Another rash of accidents closed both inbound and outbound lanes of the Mercier Bridge. The closure stranded motorists for hours as First Responders cleaned up the mess. Ontario Provincial Police reported over 40 collisions across their portion of eastern Ontario, including Ottawa and Cornwall.

There were dozens of other accidents reported across the region, many involving single vehicles hitting the ditch. Snowfall accumulations were highly variable, often depending on elevation. The Montreal area had 5-10cm, with 15-30cm falling from Laval north into the Laurentians.

The 6cm of snow that officially fell at Trudeau Airport Tuesday, was enough to push Montreal over the 200cm mark for the season, to 204.9cm (80.7 inches)

Overnight temperatures were very cold, dropping to -8C here on Ile Perrot, into the minus teens north and west of the city. Another round of accidents occurred on very ice roads during the morning commute. The temperature has slowly warmed above freezing Wednesday afternoon, allowing for most of the ice and snow to melt off area roads.

That may have been winters parting shot, as much milder air in now forecast beginning Thursday and persisting to the end of April. May snow, while not impossible, is very rare in Montreal!

Over 20 vehicles were involved in a serious accident on Highway 13 southbound between Laval and Montreal on Tuesday evening. The highway remained closed for several hours while First Responders cleared the scene.

Winter's parting shot?

Grey skies and a light dusting of snow are greeting Montreal early Tuesday morning, as low pressure moves along the US border. What could be the last snow of the season today, will accumulate a few centimetres in the city, up to as much as 15cm north and west of Montreal and across parts of the Eastern Townships. (Valley Weather Photo)

Low pressure moving along the International border early Tuesday morning, is spreading a mix of wintry precipitation across southern Quebec. Roads in many cases are slick, so expect slow travel today. Strong west winds behind a cold front early this morning, are dropping temperatures and changing any mixed precipitation to snow, which will persist in various intensities throughout the day.

Light snow is falling Tuesday morning across a wide swath of our area from eastern Ontario into western Quebec and northern New England. Depending on where you are located in the region, you have a dusting up to several centimetres of fresh snow on the ground. The highest elevations of the Eastern Townships and northern Vermont could see up to 25cm of snow by Wednesday morning.

In Montreal, it took most of the overnight hours for temperatures to fall to the freezing point, and snow to begin. Most of the accumulating snow has fallen north and west of Montreal, including Ottawa. Here in Montreal, there is just a dusting on grassy surfaces as well as your car. However snowfall warnings have been issued for Ottawa and parts of eastern Ontario, with 10-15cm expected. Keep this in mind if your travels today take you along Highways 401, 416 or 417.

Drive carefully today, as temperatures are falling and will remain below freezing for the entire day. Any further precipitation will be in the form of snow, with an additional 5cm possible for most locations. Winds will be gusty, out of the northwest 40-60km/h. Our high will actually drop to -4C (25F), and fall further to a vey chilly April low of -8C (18F). On Wednesday, we can expect partly cloudy skies, with a blustery high of 1C (34F). The normal high for mid-April in Montreal should be close to 10C (50F).

Mild and wet weather returns for the weekend, as low pressure moves along the eastern seaboard.

Rainy and chilly weekend forecast for southern Quebec

Quebec Public Security is currently monitoring the flow of several rivers in the Montreal region. Water levels are slowly on the rise in response to a wet start to April, combined with warm temperatures, melting snow and ice. More rain is forecast this weekend.

The sun finally broke out on Friday, albeit slightly cooler than Thursday, when south winds pushed temperatures into the upper teens. After a chilly morning low at the freezing point, along with wet snow, I managed a high of 21C (70F) on Ile Perrot Thursday afternoon. Under bright sunshine Friday, we should make it to 10C (50F).

Mixed precipitation late Wednesday, eventually gave way to scattered thunderstorms along with some heavy rain into the morning hours on Thursday. Trudeau Airport reported 24 hour rain totals of 25.4mm, I measured 32.4mm on Ile Perrot. 

All that rain, combined with any remaining snow and ice that is melting, has caused area rivers to be on the rise. Quebec Public Security is currently watching 8 rivers and lakes in the province, most of those in the southwestern corner, including Lake of Two Mountains at Sainte-Anne-de-Bellevue and the Rivière des Mille Îles at Terrebonne and Deux-Montagnes. Levels are also rising along the Ottawa River from Ottawa to Montreal.

All rivers will be watched closely this week as another wet and windy area of low pressure moves to the south of Montreal. This system will bring steady rain on Saturday, tapering to showers on Sunday. Between 15-25mm of additional rainfall is possible through Sunday.  The weather will be raw and windy this weekend, with temperatures just above the freezing point for many locations. There is a chance of some mixed wet snow or freezing rain at the onset on Saturday, especially for locations north of Montréal and in the Ottawa Valley.

Gusty winds of 30-60km/h are likely for the St. Lawrence Valley.

Another storm will take aim at southern Quebec on Tuesday, with a mix of rain and snow expected. Temperatures will be quite cold to start the work week. 

More rain and freezing rain forecast for southern Quebec

More rounds of freezing rain and rain are forecast for the hard-hit portions of central Ontario. Many residents remain without power, and schools have been closed since Monday. (Hydro One Photo)

A warm front will lift into the St. Lawrence Valley late Wednesday, as low pressure moves into the central Great Lakes. That front will become the focus for mixed precipitation across southern Quebec, followed by a windy and wet cold front on Thursday.

Widespread weather warnings are in effect across portions of Ontario and Quebec and adjacent New York as another storm system takes aim at our region. The system arrives late Wednesday in Montreal, with a burst of snow, followed by a messy mix of freezing rain and rain through midnight. Precipitation will switch over to rain overnight in the immediate St. Lawrence Valley as warm air surges northward. Before the changeover, some regions may receive up to 5cm of wet snow, along with 2 to 4mm of freezing rain.

On Thursday, expect rain, heavy at times, accompanied by thunder, and gusty southwest winds up to 60km/h. Temperatures were cold on Wednesday morning, dropping down to -8C (18F) here on Ile Perrot. The high Wednesday will ne near the freezing point. Temperatures will continue to warm overnight, to a high of 16C (60F) in Montreal on Thursday.

Further north and east, the cold air will linger longer, and those regions are under freezing rain warnings, as is the Ottawa Valley and large portions of eastern Ontario.

In Ontario, many regions that were hit hard by the worst ice storm since 1998, are unfortunately looking at more freezing rain and rain tonight. Strong winds will accompany the precipitation, only exasperating the tree and power line damage. Nearly 215,000 customers remain without power in central Ontario after the severe weekend ice storm dumped over 25mm of freezing rain on the region. There are several municipalities under a state of emergency and schools in the region remain closed.

Briefly looking ahead, we have more unsettled weather expected this weekend, with a mix of rain and snow forecast, Details to follow.

Montreal spared from the worst of the weekend storm

While Montreal was spared the worst of the weekend ice storm, such was not the case across central and eastern Ontario. Above, Hydro One crews clear away debris in an effort to restore power near Barrie, Ontario on Sunday. Nearly a half million customers were without power in Ontario on Sunday. (Hydro One)

Strong low pressure moving along a nearly stationary boundary over the weekend, produced a wide area of wintry precipitation. Montreal and most of our region was spared the worst of the storm. Still the messy mix of freezing rain and snow resulted in numerous accidents, and a long list of power outages north and east of the city. Early Monday morning, Hydro-Quebec is reporting over 75,000 customers without power, the majority of those in the Laurentians and Lanaudière regions where more freezing rain fell.

Here in Montreal, anywhere from 3 to 10cm of snow fell early Saturday from southwest to northeast across the region. Officially, Trudeau Airport reported just over 3cm, while I measured 6cm on Ile Perrot. That was followed by an additional 21.1mm of rain, much of that freezing on power lines and trees. The good news for extreme southern Quebec was that most of the precipitation fell at a slow rate, with melting occurring in between. The lessened the ice accretion on trees and power lines, sparing Montreal from the worst of the storm. 

Such was not the case north of Montreal where the freezing rain continued, at times heavy, into Monday morning. In Ontario, heavy amounts of freezing rain, often accompanied by thunder and lightning, spread from Lake Huron inland across central portions of the province on Friday evening into Saturday. Many regions were hard hit with 25 to 50mm of ice, including Barrie, Peterborough, Goderich and the Muskokas to name a few. Significant damage has occurred to trees and the power grid. As of Monday morning, nearly 400,000 residents remain in the dark. Despite the heroic effort of the utility crews, the damage is severe, and the power may be out for days. Several central Ontario communities have declared a State of Emergency on Monday, closing schools and advising resident to stay off debris filled roads.

Thousands of trees have been damaged or destroyed across Ontario, many falling onto homes and cars. The focus of the ice storm was from northern Michigan, across central Ontario and into central New York State, just southwest of Montreal.

Temperatures will warm quickly on Monday across the entire region, helping to melt the ice, but with an added problem. Gusty southwest winds are forecast across the southern Ontario and Quebec Monday, between 40-60km/h, backing to the northwest tonight behind a strong cold from, 30-50km/h. This will cause additional damage to the weakened and ice loaded trees and power lines across the most hard-hit regions.

Here in Montreal, we can expect a very warm and windy Monday, with a high near 15C (59F). Some showers and perhaps a rumble of thunder are possible. Much colder weather returns tonight and Tuesday, with overnight lows dropping rapidly to -3C (27F). Tuesday will be partly unny, and colder with a high of 4C (39F). 

More stormy weather is on the way for Wednesday, more on that later.

Freezing rain warning for Montreal Sunday

A significant amount of freezing rain is forecast for parts of southern Quebec and eastern Ontario this weekend. Montreal is forecasting up to 10mm of ice accretion, while parts of central and eastern Ontario may see up to 25mm. Travel will be poor and power outages are possible.

Freezing rain warning in effect for Montreal.

A rather impactful spring storm is underway across extreme southwestern Quebec and portions of Ontario and adjacent New York and New England. A frontal boundary to our south has been the focus for areas of snow and freezing rain overnight. Across the Montreal region, several centimetres of snow have fallen, but the heaviest precipitation remains southwest of the city. With that said, roads are still snow covered and slippery this morning, especially southwest of the city on Highways 20/401 to Cornwall and Highway 40/416 to Ottawa. The Ottawa Airport was reporting 0.8km visibility in heavy snow at 4am. Gusty winds are forecast from the northeast 30-50km/h today.

Across portions of central and eastern Ontario, significant amounts of freezing rain fell overnight with power outages increasing in the region. Scattered thunderstorms with freezing rain were even observed. Over 25,000 residents are in the dark, and that number is increasing.

For Saturday, Montreal will remain on the cold northern side of the front, with light snow tapering off by midday. High temperatures will struggle to reach 0C (32F). There will be a break in the precipitation this afternoon, before the front begins to move northward tonight, A surge of unseasonably warm air will move over the cold air at the surface here in the St. Lawrence Valley, producing widespread freezing rain tonight and most of the day Sunday in Montreal. Up to 10mm of freezing rain is possible, resulting in slippery roads and sidewalks, as well as scattered power outages.

The front will eventually move north of Montreal, allowing much warm air to arrive, and changing any remaining precipitation to rain late Sunday into Monday. Highs on Monday will reach 14C (56F). There will be a strong cold front arriving late afternoon, with showers and even a rumble of thunder possible, followed by much colder weather for Tuesday.

Partial solar eclipse visible across eastern Canada Saturday morning

If you live in extreme eastern Canada or the northeastern US, dust off your solar eclipse glasses from last April. A partial solar eclipse will take place at sunrise across eastern Canada on Saturday morning, March 29. The eclipse will be most visible across portions of Northern Quebec and Nunavut, where up to 90 percent of the sun will be shaded by the passing moon. That includes nearly 92 percent in Iqualit. By comparison Montreal will have a maximum of 47 percent with St. John's and Halifax at 83 percent.

Across the remainder of Quebec from the Ontario border east, as well as portions of Vermont, New Hampshire, Maine and Atlantic Canada, the eclipse will range from 8 to 45 percent.

Here in Montreal, stormy weather will likely spoil the celestial view at sunrise. But if skies were clear, the eclipse would begin at 5:29AM, becoming visible with the sunrise around 6:39AM, reaching maximum at 6:42AM and ending by 7:13AM. The visible portion will last approximately 34 minutes here in Montreal, and cover up to 47 percent of the sun. Once again, the weather will likely not be favourable for viewing.

As with any solar eclipse, it is important not to stare directly into the sun. Approved solar eclipse glasses must be worn at all times to view the eclipse or stare directly into the sun at any time. Damage can occur very quickly to your eyes.

If you are fortunate enough to have clear skies at your location, then enjoy the view, have fun and be safe.

Significant ice and snowstorm possible Saturday for Ontario and Quebec

Winter battled back in Montreal this week, with chilly temperatures and plenty of snow showers and squalls. Another round of winter weather is on the way for the upcoming weekend. This weather should not be a surprise to anybody who has lived in Montreal for more than 5 minutes. Late March and April have historically produced some big storms for the city. (Valley Weather Photo)

Special Weather Statement posted for Montreal and Ottawa for a significant late season winter storm this weekend.

High pressure is providing us with a sunny, cool Thursday, after a week of clouds and flurries. Some of the flurries were heavy at times, reducing visibility and glazing roads. With chilly overnight lows at or below freezing, there has been plenty of black ice, resulting in some serious accidents. 

After the sunshine of Thursday, we have a very complex weather scenario setting up for the weekend. Arctic high pressure lies to our north, along with an unseasonably strong Bermuda high to our south. The St. Lawrence Valley will become the battleground between the two airmasses. 

A front will lie just to our south, with low pressure riding along it late Friday and again on Sunday. Heavy precipitation will fall along and to the north of the front. This boundary will separate very warm air, over 21C (70F) surging north into southern New England from sub-zero temperatures, -2C (29F) here in Montreal. Northeast winds will keep surface temperatures below freezing in Montreal into Sunday.

There are lots of details to work out, including the exact location of the front. Some areas in southern Quebec and eastern Ontario can expect heavy snow, followed by a significant amount of freezing rain. Despite the angle of the warming March sun, the April 2023 ice storm taught us the significant damage can still be done from freezing rain in spring.

At this time in excess of 25mm (1 inch) of precipitation is possible for Montréal over the weekend. Some models are showing as much as 50mm. The storm will come at us in all forms from heavy snow Friday and Saturday, to freezing rain and eventually rain on Sunday and Monday.

Plan on difficult travel conditions as well as the potential for tree damage and power outages. Stay tuned for updated forecast and warnings over the next 24 hours. This story will be updated.

Winter strikes back in Montreal

The City of Montreal prematurely started cleaning away winter debris last week, a full two weeks ahead of schedule. Unfortunately Mother Nature has the last laugh Monday morning a more snow fell. And we may not be done with the snow just yet. (Ville de Montreal)

More snow expected this weekend.

The City of Montreal started their spring cleaning last week, a full two weeks ahead of schedule, thanks in part to what Mayor Plante called "climate change". With all do respect to Madame Plante and our warming climate, this is March in Montreal. Anybody who has lived here for more than 5 minutes knows that winter is not really over until around Easter as a rule. Even then, it has snowed in Montreal in May!

Several centimetres of snow surprised commuters early Monday morning, covering roads quickly and resulting in several serious collisions. The snow gradually changed to rain in the afternoon. More snow is on the way for the upcoming weekend. (Valley Weather)

And so it goes, Monday morning, a warm front lifted across the region accompanied by a pretty decent shot of snow. Unfortunately the snow arrived during the morning commute, and resulted in several serious accidents, including one that closed Highway 20 near Les Cedres off the western tip of the island. Montreal provided very little in the way of sanding and salting, so it was up to motorists to navigate snow covered and icy roads. The snow gradually tapered off to showers in the afternoon, but not before depositing a few centimetres and raising the monthly total up to over 10cm. A significantly smaller amount when compared to February for sure, but disruptive nonetheless.

The same weather impacted eastern Ontario on Monday, with a rash of  accidents being reported form Ottawa down to the Seaway Valley.

Many drivers heave already removed their snow tires, something I would not recommend until at least mid-April, despite what the rule reads.

Looking ahead, we have a very unsettled, rather chilly week ahead. Showers will mix with flurries at times Tuesday and Wednesday, with temperatures in the single digits for highs. High pressure will build into southern Quebec briefly on Thursday, with sunshine and milder temperatures. The active weather will return this weekend, with a stronger storm moving from the Ohio Valley towards southern Quebec. Another period of wet snow and rain is possible, with some accumulations likely. 

Winter is not quite over. Please drive safe.

***On a personal note, I want to thank all my readers, family and friends for your kind words and notes over the loss of my trusted weather companion Bella. It has been a sad week for me as I navigate the new normal without my furry sidekick of 14 years. Read about my Bella HERE.

Saying goodbye to Bella - my all-weather pup

My beloved all-weather pup, Bella, the little dog with the big heart and attitude to match. She was my world. I will miss her every second of every day.

On a beautiful first day of spring in Montreal, I said goodbye to my beloved pup Bella. At 16, Bella had developed some serious health issues over the last two weeks and let me know her work here was done. It was the most difficult decision I have had to make in my entire life.

Bella came to us from Kiko Dog Rescue in 2011. A misfit of sorts, she was a perfectly imperfect terrier with a heart of gold and the idea that somehow, she was bigger than her 20 pounds. She quickly showed me why,  you see Bella, was a survivor. Born at a puppy mill and passed around to several homes, she had an edge that we softened quickly. I understood her. She understood me. And so forged a relationship that would flourish for 14 strong years. Bella loved me, her greeting every night was epic. Our neighbours knew when I was home. Bella and I shared our space, our time. We had a profound respect for each other, we even shared Chapman's vanilla frozen yogurt.

So why talk about her on my weather blog? Bella was an all-weather dog. We walked daily, often 2-3 times everyday, regardless of the weather. By my count over 14,000 walks in those 14 years. Most of the images you see on this blog were taken with her by my side or in the car with me.

We walked in every type of weather, without fail, heavy snow and rain, warm or cold. Every day. Every season. We both loved fresh snow. Bella loved chasing falling leaves. During the April 2023 ice storm, we walked in darkness during the early morning hours, around downed trees, and cuddled on the couch for warmth as power was out for days. As well we watched countless sunrises and sunsets.

Most recently we viewed the ending stages of the lunar eclipse. Bella was an early riser, motivated by the thought of breakfast after our walk. Followed by some couch time, while I reviewed the different forecast discussions and commuter weather models.

Bella and I visited the historic weather office in Hatteras, North Carolina on the Outer Banks in September 2018. (ValleyWeather Photo)

Bella even accompanied me to one of the first weather offices on the Eastern Seaboard when we visited Cape Hatteras, North Carolina in September 2018, just after hurricane Florence. Our trip was almost cancelled due to the storm, but in the end the barrier islands were reopened just in time.

Bella never failed me. Her love was pure and unconditional. She knew me, I knew her. Eagerly she would wait at the door every morning, even in her final days. Today, Friday, March 21, there was no walk for the first time in 14 years. Bella thought I had all the answers. I thought she did. I had no answer for this. The grief is deep. My heart is broken. They say time heals, we shall see.

Late season winter storm brings tornadoes, blizzards, flooding and record warmth

A Missouri State Highway Patrol Police cruiser illuminates the immediate aftermath of a powerful tornado, still visible in the background, near Bakersfield, Missouri. Three fatalities were reported form this storm, with 35 across the US from dozens of tornadoes since Friday evening. The same system produced record warmth in southern Ontario and Quebec.

A powerful late season winter storm is lifting into the Great Lakes on Sunday afternoon, dragging a potent cold front across eastern Ontario and eventually southwestern Quebec. The storm has been responsible for numerous fatalities as it moved northward. A wide range of weather has accompanied the storm, from dust storms and hurricane force winds, to wildfires, tornadoes, flash flooding and even heavy snow along the western edge.

The heavy snow and strong winds are impacting parts of central Ontario on Sunday. Meanwhile here in southern Quebec, record warmth has spread into the region. On Saturday, Montreal reached 17.3C (63F), shattering the 1913 record for the date of 12.8C (55F). So far on Sunday, we have tied the 2010 record, currently at 13.1C at Trudeau Airport. The hot spot in the Quebec on Saturday was 19.4C (67F) at Beauceville.

South of the border, an intense outbreak of severe weather resulted in dozens of tornadoes across several states from Missouri to Pennsylvania and south to the Gulf Coast. Nearly 35 deaths occurred from the tornados, with a least a dozen more form major car accidents as a result of blowing dust in Texas and Kansas. Damage is complete in many small communities form powerful tornadoes, including Bakersfield, Missouri, Diaz and Cave City in Arkansas.

In our region, the very warm temperatures, melting snow and ice along with today's rainfall, is raising concern for river flooding. Several rivers in the region are on the rise and being watched closely.

There is a risk of a few showers and thunderstorms Sunday afternoon in southern Quebec, along with gusty winds up to 60km/h. The cold front will clear the region overnight, setting us up for clearing skies on Monday, along with more seasonable temperatures. The high is forecast to be only 2C (35F). Monday night will be quite chilly, dropping own to -8C (18F). The middle portion of the week will see mild temperatures return, along with showers.

Lunar Eclipse visible in Montreal Friday morning

A total lunar eclipse will take place in the wee hours of Friday morning, visible across all of North America, including here in Montreal. The eclipse begins just prior to midnight Thursday at 11:57PM, reaching maximum totality at 2:58AM Friday morning, and ending completely by 6AM, lasting a total of 6 hours and 3 minutes.

Totality will occur between 2:26AM and 3:31AM.

The eclipse of the full worm moon will occur as the earth passes between the sun and the moon. The moon will take on a reddish copper hue, often referred to as a blood moon. The weather for the event will be near-perfect in Montreal and across southern Québec and eastern Ontario, with clear skies, light winds, and a temperature around -4C (26F) expected.

Unlike a solar eclipse, there is no zero-danger in watching the lunar event. Dress warmly, grab your camera, tripod or binoculars and enjoy the celestial show.

The next total lunar eclipse will be on March 3, 2026.

After record warmth - a flash freeze for Montreal

The weather this March has been highly variable, typical of the first month of spring as the air masses battle it out. Temperatures have swung wildly, with a mix of rain and snow. To date 8.6cm of snow has fallen at Trudeau Airport, along with  8.2mm of rain. After the sharp cold of Tuesday night and Wednesday, very warm air will return for the weekend along with rain. (Valley Weather Photo)

Flash freeze warning posted for southern Quebec Tuesday evening 

Temperatures soared into the low teens in Montreal on Tuesday, on strong and gusty south winds between 30 and 50km/h. The high reached 15C (59F) on Ile Perrot, slightly lower at Trudeau Airport, with 12C (54F). The record for the date was 11.8C (53F), set in 2021. Clouds have been on the increase all afternoon, as a strong cold front is moving east across Ontario towards Montreal.

A flash freeze warning has been issued for southern Quebec, with temperatures expected to fall rapidly behind the front. Winds are forecast to back to the west, and gust between 40 and 60km/h Tuesday evening. Showers will develop along the front and briefly mix with wet snow before ending by midnight. Any standing water will freeze as temperatures fall below freezing, down to -11C (12F) by morning. Windchill values will approach -18C (0F), a nearly forty degree plunge from Tuesday afternoon's high temperatures.

Wednesday will be blustery and chilly, with highs near -3C (27F). The good news is that the cold snap will be short-lived, as very warm temperatures along with rain return by the weekend. However, the threat for flooding will be on the rise as ice and snow across the region begin to melt quickly.

Chilly, windy weekend for Montreal - warmer weather returns next week

Frozen in Time!
Several vehicles remain parked along Dr. Frederik-Philips in Saint-Laurent, seemingly frozen in time. Huge mountains of snow remain in parking lots around the city. A thaw began this week as temperatures warmed well-above freezing for several days, accompanied by rain. Officially Trudeau Airport is reporting only 4cm of snow left on the ground, unofficially I have several of feet left in my back yard! (Valley Weather Photo)

Spring forward Sunday morning at 2AM, as Daylight Saving Time returns to most of North America.

Montreal had a brief taste of spring this week, accompanied by mild temperatures and rain. Monday, was the coldest morning of the winter in Montreal at -22C (-8F), followed just as quickly by the warmest high of the year to date on Wednesday, when the mercury rose to 8.7C (48F). A period of wet snow late Monday quickly transitioned to rain before a strong cold front arrived late Thursday. Amounts were lighter than forecast with 5.4cm of snow so far this month, and 8.2mm of rain.

The bulk of the moisture remained to our west as a powerful late winter storm moved from Colorado to the Great Lakes. Blizzard conditions spread from Iowa into western Ontario, with severe weather and tornadoes on the warm side of the storm from Texas to Ohio. Rain and very warm temperatures rose the risk of river flooding across New England.

Late Thursday, temperatures fell rapidly, along with a centimetre or two of snow, as a strong cold front pushed across the region. High pressure will briefly build into southern Quebec Friday morning, but the weather will remain unsettled through the upcoming weekend. A series of weak disturbances in the upper atmosphere will produce clouds and occasional flurries from late Friday through late Sunday. Winds will be gusty, up to 60km/h today and Saturday. Temperatures will be below normal for the weekend, remaining below freezing, but will warm significantly next week, with more rain possible.

At this time, no major storms or on the horizon, along with a general warming trend. Could this finally be the end of winter! Time will tell.

Warmer, rainy weather returns this week to Montreal

Roads were slick on Ile Perrot early Saturday morning after 9cm of snow fell overnight at my home. Amounts ranged from 8 to 15cm across southern Quebec, but oddly only 5cm officially at Trudeau Airport, just 25km northeast of my location. Strong winds gusted over 50km/h Saturday afternoon and Sunday producing areas of blowing snow, cold windchills and slippery road conditions. Much warmer weather returns this week, along with rain. (Valley Weather Photo) 

Special Weather Statement posted for southern Quebec for heavy rain midweek.

Monday morning was the coldest of the winter so far at Trudeau Airport, with the temperature dropping to -22C (-8F). This should stand as the coldest for the season, with milder air returning this week, and no polar air in sight through March. Spring is really just around the corner!

For the short-term, we are looking at a chilly Monday, but not as cold as Sunday's . Winds will be much lighter, and the warm March sun will help temperatures climb from the deep freeze up to -5C (23F). The balance of the week will be unsettled to say the least. Clouds will increase Monday night ahead of a warm front lifting across the Ohio valley and Great Lakes.

Strengthening low pressure will move from the southern US plains towards the Ottawa Valley by midweek, pushing a warm and increasingly moist airmass over southern Quebec and eastern Ontario. The result will be a moderate round of precipitation, starting as snow late Tuesday in Montreal, but changing over to rain by Wednesday morning. There may be some brief freezing rain in the transition, but any ice accretion would be minimal.

The bigger concern will be the 15-25mm of rain expected on Wednesday and Thursday, as temperatures soar above freezing to 6C (43F). With frozen ground, ice covered rivers and mounds of deep snow around, flooding is a possibility. Make certain any drains, sewers and downspouts are clear of snow and debris.

Over the weekend an additional 10-15cm of new snow fell across the region, officially 6cm at Trudeau Airport, but I measured 9cm on Ile Perrot.

Behind the storm on Friday, we can expect colder weather, with a high of -1C (30F), along with scattered flurries and gusty winds.

A look back over 50 years: The Montreal Blizzard of 1971

MARCH 3-5, 1971: 47cm of snow, 110km/h winds, 17 hours of blizzard conditions in Montreal. 

Click below for the full story, interviews, photos and memories.

Today marks the 54th Anniversary of the storm of the century in Montreal. A fierce blizzard brought Montreal to a standstill for several days. You can read the full story HERE.

The streets were clogged with deep snow for days. Power was out to tens of thousands across the province. It was a true storm.
