This same storm will impact regions from Minnesota to New York today into Monday with a wide range of warnings posted including a blizzard warning for northeast Illinois and Chicago. Warnings are in effect for southern Ontario as well as all of northern New York and Vermont. The storm will impact New England into Atlantic Canada on Monday. Thousands of flights across the Midwest have already been cancelled. The snow will also hit Punxsutawney, Pennsylvania on Monday where Phil will give his annual February 2 Groundhog Day prediction for the rest of the winter.

The weekend will be sunny but cold with highs only near -15C (5F) and lows down to -22C (-8F) in Montreal. The cold will last well into next week with well below normal temperatures forecast. The only good news, the rain falling in Phoenix, home of the 2015 NFL Superbowl, will stop in time for Sunday's big game. It will be sunny at game time with a forecast high of 19C (67F). GO PATS!

Special Weather Statement posted for most of eastern Ontario and portions of southern Quebec for snow and blowing snow. Winter Weather Advisory for the St. Lawrence Valley of New York and northern Champlain Valley of NY & Vermont. No warnings yet for Montreal but it will be an "advisory" type snowfall if Environment Canada used such terminology.
Low pressure will move from the Great Lakes today down the St. Lawrence Valley bringing snow and blowing snow to Montreal, Ottawa and Quebec City starting late today and lasting into Friday. The storm is rather disorganized in nature but will still bring us more snow than we have seen at any other time in January. We start the day at -20C (-4F) on L'Ile Perrot, clear and cold once again, a theme that has been replayed countless times this January. Clouds will increase today with snow developing by late afternoon from Kingston to Cornwall before moving into Montreal by the evening commute. Once it starts it will snow steadily until noon or so Friday. Expect a good 10cm (4 inches) in most locations with 15cm (6 inches) right along the St. Lawrence River, including metro Montreal. Temperatures will warm today to -4C (25F) and up to -1C (30F) early Friday morning, before an arctic front plunges the temperature down to -13C (9F) by days end. It will turn windy as well Friday, gusting up to 50km/h causing blowing snow in Ontario and Quebec. Driving may be challenging at times. Skies will slowly clear Friday night setting up a sunny but very cold weekend. Lows will be near -22C (-8F) with highs no better than -13C (9F).

SNOW FOR MONTREAL
Looking ahead we can expect clearing skies today across the region, but it will be cold, only -10C (14F). Clear skies tonight with a low of -14C (6F) will give way to increasing clouds on Thursday as the next low pressure area approaches form the Great Lakes. It will be milder Thursday with a high of -6C (21F). We can expect snow to start late in the day in eastern Ontario and spread into Quebec by the evening commute. Steady snow and gusty winds are likely into Friday morning with a good 10cm (4 inches) expected in Montreal and Ottawa. It will turn cold again for the weekend with another shot at measurable snow by Monday. More on that as the week progresses.

In Quebec, any snow expected is sill limited to the border regions as well as the Gaspe where warnings are posted. Only 1cm or 2 is forecast for Montreal. Strong winds will funnel down the St. Lawrence Valley with gusts to 90km/h forecast in Quebec City, and already approaching 60km/h in Montreal. It is very cold in Montreal this morning with windchill readings around -26C. (-15F). The high will only be -11C, windy, cold and flurries.

A powerful and perhaps historic Nor'Easter is developing this afternoon off the coast of North Carolina and is expected to move towards Cape Cod on Tuesday. Rapid intensification is expected with a 40-50 millibar pressure drop in less than 24 hours forecast. Heavy snow is already falling well in advance of the main storm across southern New England and metro New York City. Forecast blizzard conditions are expected overnight with accumulations reaching 12-24 inches and even up to 36" from metro NYC northeast into Massachusetts. Strong winds are forecast up to 65mph. Coastal flooding is also a big concern with warnings now posted. Thousands of flights have been cancelled already in northeast hubs with the prospect of a complete shutdown Tuesday in New York and Boston. A travel ban has been declared in Massachusetts for Tuesday. This storm could rival the historic Blizzard of 78. Away from the coast heavy snow is forecast northward into central Vermont and New Hampshire. Blizzard conditions are also forecast for New Brunswick, Nova Scotia and P.E.I. Heavy snow will fall along the Gaspe coast of Quebec.
|Latest forecast amounts as of 3:30pm Monday|
Effects in Quebec
In southern Quebec strong northeast winds will develop on Tuesday gusting from 60km/h in metro Montreal up to 90km/h in Quebec City where warnings are in effect. Windchill values will be very cold with a high of only -11C expected and windchill readings down in the minus 20's. As far as snow goes, we are looking at 5cm for Montreal tomorrow evening, and upwards of 10-15cm for the Townships into the Beauce. Blowing snow will greatly reduce visibility in and east of Quebec City Tuesday night.
|Montreal, once again, will remain on the western edge of a coastal snowstorm.|
Powerful Historic Nor'Easter
That brings us to the current storm, a weak, unsuspecting area of low pressure meandering across the Ohio Valley this morning. That system will move off the middle Atlantic coast today and explode into a powerful Nor'Easter. The storm will then slowly move northeast towards Nova Scotia over the next 48 hours. With arctic air in place, copious amounts of Atlantic moisture will be drawn into New York and New England producing historic snowfalls in some locations. The computer models are indicating 2 to 3 feet (60-90cm) of snow in a swath from metro New York and New Jersey into central Massachusetts. In addition to the snow, strong winds will gust to hurricane force along the coast and perhaps 50mph inland. Visibility will be nil in snow and blowing snow with travel nearly impossible on Tuesday. Coastal flooding will also impact the region especially along the flood prone Massachusetts and New Hampshire coasts. With blizzard conditions forecast, expect major travel delays anywhere along the east coast on Tuesday and perhaps Wednesday. The storm will also impact interior portions of New England, Quebec and Atlantic Canada with 15-30cm of wind whipped snow.
At this time, the St. Lawrence Valley and Montreal are expected to remain on the western edge of the storm with a cold northeast wind to 60km/h as well as a few flurries. Snowfall amounts in the city will be light as high pressure over us will limit mositure. As you move south and east towards Sherbrooke and Vermont, snow amounts will increase to between 5-15cm. Beyond the border area it just keeps getting deeper as you head south and east. I strongly recommend postponing any travel plans that take you into New England or east into portions of the Gaspe or the Maritimes Tuesday.
