The end of summer 2013

It is so hard for me to believe summer is over. As with many in Canada, it is my favorite season and always has been. When we look back at summer 2013, most people say the same, it was ok, just ok. Nothing spectacular either way with just the one heatwave in July and pretty much near normal weather the rest of the time. I know there were plenty of thunderstorms around the region, especially Vermont, but as far a L'Ile Perrot goes, not so much. One strong storm so far and otherwise most missed the Island to the north or south. There has been a little more cloud and showers and far too many 23C days for my liking!

Summer 2013 will end on a muggy note across the entire region with showers developing later today and showers and thunderstorms expected for the long Labor Day weekend. Temperatures will be near 27C (80F) in most areas from the St. Lawrence Valley into New England. The humidity will make it feel a little warmer. The best chance for stronger thunderstorms will be on Saturday. The warm and humid weather will continue into early next week before a cold front brings some September weather by Wednesday.

Humid in Ontario & Quebec - more flooding in Toronto

It remains very hot across the Midwest and upper lakes and extremely humid in Ontario and Quebec. A warm front remains stalled over the region with a very stagnant air mass in place. High dew points and relative humidity readings have lead to widespread dense fog this morning. Both Montreal and Ottawa are reporting less than 0.6 km in fog. Motorists should adjust their speeds until the fog lifts later this morning. It will remain muggy and misty with the risk of showers and thunderstorms this afternoon. Some of the storms could produce heavy rain, especially in southern Ontario.

On Tuesday soaking thunderstorms stretched across central Ontario with flash flooding reported once again in parts of Toronto. The rain and thunderstorms are occurring along the periphery of a very hot air mass that has pushed temperatures to there warmest readings of the summer in Minnesota, Wisconsin, Illinois and Indiana. The heat has spread west into Manitoba and Saskatchewan where both Regina and Winnipeg were 33C (92F) on Tuesday.

Late summer heatwave

Very hot weather is blanketing the upper Midwest, western Great Lakes into portions of northwest Ontario and the southern Prairies. It has not been a great summer in the Midwest with lots of cool, wet weather but such is not the case this week. Temperatures will soar into the low 30's from Regina to Thunder Bay. South of the border Minneapolis is already 80F this morning on the way to 95F. Excessive heat warnings and advisories are in effect across that region. The heat will last through the Labor Day weekend.

Meanwhile along the periphery of the warm dome of air, showers, thunderstorms and very humid weather prevails from the eastern Lakes into southern Quebec. Most of the wet weather yesterday remained in Ontario and such will be the case today as well. It will remain that way through most of the week. Temperatures today in Montreal will reach 27C (80F) but with high humidity, 94% this morning, and dew points in the low 20's making it feel uncomfortable. It is misty and muggy this morning in Montreal and already 21C (70F). So back to school this week will be warm especially in those older schools without A/C.

Warm and humid week for Quebec & Ontario

We are off to a muggy start to the week across Ontario and Quebec this morning as a warm front slowly crosses the Great Lakes. Most of the activity is over the central lakes this morning into the GTA. Some storms have produced torrential rains with up to 30mm overnight. Montreal remains on the edge of the activity with only about 5mm overnight. Temperatures are warm this morning near 20C with a high humidity reading of over 90%. It will be muggy all day with scattered showers and storms. Temperatures will reach 26C. The balance of the week looks similar with some sunshine but also showers and thunderstorms. Drier air will move into Montreal by Thursday but it will remain warm well into next weekend.

Tropical Storm Fernand developed rapidly on Sunday and will dissipate just as rapidly today over central Mexico. The storm formed in the Bay of Campeche and moved inland to be about 60 miles northwest of Veracruz this morning. Winds are near 45mph with weakening forecast today. As always with tropical systems in Mexico, heavy rain and flooding will be the main threat today. Between 4 inches
and as much as 1 foot of rain is forecast.

Another spectacular weekend for Montreal

High pressure has settled into the region this morning as a cold front slides off the New England coast. Temperatures are a little crisp around the area with a hint of fall in the air. Temperatures range from 12 to 16C with a very heavy dew. It will warm quickly today with afternoon highs up to 23C. The weekend looks perfect for anything outdoors with sunshine and high temperatures in the 25 to 27C range.

On Wednesday warm air surged into the area for what may be the last 30C highs of the season. Several records were broken including 30C (86F) at St. Anicet/Lancaster. I recorded 30.0C here as well on L'Ile Perrot, the warmest temperature for August. It was slightly cooler at the airport as usual, reaching 29C.

Showers and some thunder on Thursday produced a little over 13mm (0.5") rainfall here on the island. Welcome moisture for the lawns and gardens. Both Trudeau and Ottawa had about 8mm, while St. Hubert on the South Shore recorded the same as here at home, around 13mm.

Hot weather for back to school

While many Quebec kids are getting ready to head back to school next week, the weather has finally turned more summer like. Temperatures have returned to near 30C in southern Ontario and Quebec, with increasing humidity expected today. Forecast highs of 29 to 32C (85-90F) are expected across the region. A cold front is entering central northeast Ontario and far northwest Quebec today with showers and some strong thunderstorms. That front will settle across southern Ontario and Quebec by Thursday afternoon. Look for sunshine today and early Thursday in Montreal before clouds increase with showers arriving by early afternoon. Severe weather is unlikely but a few of the storms may be strong with hail, gusty winds and heavy rain by Thursday afternoon. Behind the front temperatures will cool for Friday to normal values of 23C with the air drying out. The weekend looks fair and mild with normal highs around 24C and lows around 14C.

Sunshine - warm for Quebec & Ontario

Temperatures on Sunday reached around 27C (80F) in most of southern Quebec with a southwest breeze and plenty of sunshine. The forecast is very simple for most of this work week, sunny and dry with temperatures between 28 and 32C. (85-90F). An increase in humidity by Thursday will result in more clouds and perhaps some thunderstorms by late in the day. Conditions will turn cooler by Friday. Until then enjoy the outdoors, the weather will be perfect.

Winter?
After record breaking heat early in August, parts of the high Arctic have come back down to reality. A snowfall warning was in effect overnight for Grise Fiord in Nunavut where 15-25cm of snow was forecast. It is -1C this morning with light snow from Grise Fiord north into Eureka and Alert. The week looks cold with occasional flurries and temperature below freezing.

Spectacular late summer weather

We all know summer is in the waning moments. This is always hard to take, especially if you are a summer lover like myself. It honestly has not been a great one at so many levels, but it is still summer, and a bad summer is better than a good winter. Today will be similar to Thursday with warm sunshine giving way to clouds and a slight risk of a shower or thunderstorm. That will be the last raindrops for quite some time. High pressure will park itself over southern Quebec for the next week with sunshine and temperatures warning to near 30C early next week. Humidity will also be on the increase across the region into the middle portion of next week. But all you need to know for the time being is that the weekend will be perfect across southern Quebec, Ontario and New England, sunny, dry and warm. Enjoy!

Big thunderstorms sweep Montreal

A late evening cold front crossed Montreal and southern Quebec on Tuesday with thunderstorms. Some of the storms produced flash flooding in parts of the city especially north of Montreal island. Here on L'Ile Perrot I only recorded a few millimeters of rain as the bulk of the activity passed north or south of my location. For whatever reason this has been the typical storm path all summer long. The front has ushered in some cool, fall like temperatures with current readings at 14C (56F). We are looking at cloudy skies today with the threat of some showers and even an isolated thunderstorm this morning. The activity will taper off as the day moves along. It will clear out tonight and be chilly with lows near 10C (50F). The balance of the week into the weekend looks spectacular with sunshine and temperatures from 24 to 28C by Sunday. Even the start of next week looks sunny and warm at this time.

The tropics are heating up as we approach the peak period of hurricane season. Forecasters at the National Hurricane Center are watching two areas of interest in the far eastern Caribbean and also the southern Gulf of Mexico. The disturbance in the Gulf could become tropical storm Erin within the next 48 hours.

Good weather week ahead for Montreal

Another sunny and very pleasant late summer day is upon us as temperatures will reach 27C (81F) in Montreal. It is breezy out of the west and that will continue but otherwise it is near perfect weather. A cold front will push across Ontario later today and into southern Quebec overnight. Ahead and along the front clouds will yield to some showers and perhaps a thunderstorm. There may be some small hail and heavy rain with any storms that do develop in Ontario today. The threat will be less in Montreal. Clouds and showers will linger into Tuesday with slightly cooler weather. High pressure then takes over the weather into next weekend with sunshine and temperatures warming up.

Arctic heatwave - Inuvik warmer than Toronto

It was 27C yesterday in Toronto, 28C in Montreal, warm for what has been generally a cool summer. However in the far north and across the high Arctic, it has been downright hot with records falling in both the Northwest Territories, Yukon and Nunavut. Yesterday Inuvik, NWT established a new record high of 30.4C (86F) beating the old record of 28.1C set in 1989. The normal high for early August is 17C (63F). More heat today and into the weekend with forecast highs of 28C. Even across the high Arctic, Rankin Inlet was 25C (77F) the normal high is 15C, and Sachs Harbor was 19C their normal high is 7C. Sunshine and warmth is forecast right through the weekend and into next week. Vacation plans anybody?

Ontario Tornadoes
Environment Canada has confirmed three tornadoes in Ontario on Wednesday bringing the total to 14 for the season. Three EF-0 (Enhanced Fujita Scale 0-5) storms occurred in Arthur/Grand Valley, Orillia and near Carnarvon. Meanwhile a waterspout was reported in the Kawartha Lakes region. The storms were capable of winds in excess of 100km/h, but thankfully no major damage or injuries were reported.

Montreal
A cold front sagged slowly south across the Montreal region overnight with showers and a rumble of thunder. About 11mm of rain fell here on L'Ile Perrot. The bigger storms remained to our south over New York and Vermont where up to 5 inches (125mm) of rain has fallen overnight. Flash flood watches and warnings are in place today in Vermont and New York south of Burlington and Plattsburgh with more thunderstorms developing in the warm and humid air. The good news is that high pressure will arrive for the weekend with mild and dry air. Look for sunshine in Montreal both Saturday and Sunday with highs near 24C (76F), perfect late summer weather.

Showers & thunderstorms southern Quebec & Ontario

This will be brief this morning, I apologize, it has been a challenging week. We start the day in Montreal with partly cloudy skies, expect increasing clouds with showers and thunderstorms developing by late afternoon into the overnight hours. Temperatures today will flirt with the 27C mark (80F) in the St. Lawrence Valley. Some thunderstorms may approach strong to severe limits with heavy rain and some hail possible especially in southern Ontario today and towards Montreal late tonight. More showers and storms are forecast for Thursday in southern Quebec with showers lingering into Friday. Right now the weekend looks perfect with warm sunshine, low humidity and highs near 25C both Saturday and Sunday.

Chilly start to a decent week for Montreal

It is a little like September this morning as reality begins to arrive for most of us. The truth is we are on the backside of summer 2013. It is not over by any means but is has been cooler and the nights are getting longer with lots of dew and even some fog around. This morning it was 9.9C here on L'Ile Perrot with lows as cold as 7C in Kemptville, ON and 2C in Saranac Lake, NY. Today will be sunny with temperatures recovering to 22C (72F), a very pleasant, low humidity day. The entire week looks good with temperatures warming to the middle 20's with the best chance for showers coming Thursday.

The skies were wild over the weekend here in southern Quebec as an upper level low traveled across the region. Both days started off dry but the atmosphere quickly became unstable with lots of showers and thunderstorms developing. Clouds were impressive playing hide and seek with the sun producing lots of rainbows. Spectacular lightning lit up the sky Saturday night here on L'Ile Perrot. There was even some hail reported southeast of Montreal.

Just another summer 2013 weekend in Montreal

The weekend weather won't be perfect, but not many have them have been in Montreal during this bizarre summer. July is over and with it record heat, record cold and lots of rain for Quebec and Ontario. Rain fell in places where it normally does not in July, like Death Valley, California (0.75"). None fell in places where it is wet all the time, like Seattle that had a trace of precipitation for July. August appears to be no different as the same weather pattern remains in place. So temperatures will soar into the high 20's near 80F in Greenland and across the far north while it remains in the low 20's (70F) across the Great Lakes and southern Quebec.

On Thursday another 10mm of rain fell on L'Ile Perrot in afternoon thunderstorms, some that were quite gusty with strong winds and torrential rain. This morning it is muggy with fog and clouds. Sunshine will break through allowing the temperature to rise to 24C (76F) and the atmosphere to become unstable once again. Look for a 40% chance of storms this afternoon. The same forecast for Saturday can be expected across the region. Sunday looks a little cooler with showers. No real hot air in sight next week as temperatures remain below normal for August in Montreal.

TD Dorian
The remains of once tropical storm Dorian are showing some signs of strengthening off the southeast coast of Florida this morning. The system will be watched closely by the NHC as it continues
to slowly drift north northeast along the coast. Gusty winds and rain will affect the coastal waters between Florida and the Bahamas today.
