Wednesday, March 30, 2016
On Friday, the first of two arctic fronts will slip south of the St. Lawrence Valley, with much colder air pouring into southern Ontario and Quebec. Winds will increase out of the northwest, up to 50km/h, along with showers both Friday and Saturday. Temperatures will begin to slowly cool Friday, with the high Saturday only 5C (41F). The really cold air arrives over the weekend, as another arctic front crosses the region. Temperatures will plummet to well below freezing Sunday, with a high of only -4C (25F) forecast. By Monday morning, low temperatures will be in the minus teens across southern Quebec. The cold will be accompanied by gusty northwest winds and some snow. It will feel like mid-winter into the early portion of next week. Snowfall, at this time, is expected to be light in Montreal, but more significant across the higher elevations of Quebec and New England, and especially close to the Great Lakes. A swath of lake-effect snow is possible this weekend and early next week.

On the backside of the storm, colder air will surge into the region overnight with rain changing to snow across eastern Ontario and southern Quebec. Most locations can expect a dusting to 2cm before the precipitation ends Tuesday morning. The temperature will fall to near -1C (30F) in Montreal overnight. Winds will become quite strong today, 30-50km/h, increasing to 50-70km/h tonight before diminishing Tuesday morning.

This morning, southern and eastern Ontario are reporting freezing rain and snow. The result has been widespread power outages, along with school closings and flight cancellations at Pearson Airport in Toronto. Travel along the 401 and 417 will be difficult today. Weather warnings are posted for all of southern Ontario and Quebec for today and tonight.
This storm's main area of low pressure has produced some wild weather over the past 24 hours. As is typical with most spring storms, this system has a big variation in temperatures. On Wednesday, heavy snow fell west of the storm track in Denver, with numerous road closures and nearly 80,000 without power. At the same time, on the warm side of the storm, strong winds were fueling brush fires in Oklahoma and Texas, with severe thunderstorms and tornadoes in Kansas and Nebraska. Today, blizzard conditions stretch across the upper Midwest from Minnesota to Michigan. Heavy snow will move into central Ontario and Quebec later today, with up to 30cm forecast.

|Another 4cm of wet snow fell on L'Ile Perrot and Montreal overnight.|
Widespread winter storm watches and warnings are now in effect across the US Midwest into Ontario, and they should be expanded into Quebec later today. Snow will begin in Montreal early Thursday along with strong northeast winds up to 50km/h. The snow will change to freezing rain late in the day and likely over to rain overnight into Friday, as temperatures warm from -4C (25F) Thursday to well above freezing Friday. Amounts of snow and ice will likely exceed 15cm over most of southern Quebec. Where the precipitation remains as snow, north of Montreal, over 25cm is possible. Skies will clear for the weekend, with warmer temperatures returning by Easter Sunday.

Spring Snow for Montreal
On Tuesday, weak low pressure will slide across the Great Lakes and along the US border. Clouds will increase early in the day, followed by light snow by evening in Montreal. A good 5cm of snow is forecast by Wednesday morning, from the Ottawa Valley into southern Quebec. Later in the day Wednesday, an arctic boundary will slip just south of Montreal, with cooler air surging into the St. Lawrence Valley. With temperatures below freezing into Thursday, another surge of moisture will arrive as low pressure develops over the US Midwest. This storm will provide Montreal, southern Quebec and parts of Ontario with a messy mix of rain, freezing rain and snow, as we head into Good Friday. At this time, the track of the storm remains uncertain. The exact path will determine what type and amount of precipitation we can expect in Montreal. Amounts may be significant, along with gusty winds. If you have travel plans late Wednesday through Friday in Ontario and Quebec, pay close attention to future forecasts. Temperatures for most of this week will remain below normal, with warmer weather expected by Easter Sunday.

|Visit earthhour.org to see how you can take part in Earth Hour 2016 this Saturday.|
Saturday, March 19th, between 8:30 and 9:30pm local time, is the 10th annual Earth Hour. Participants are asked to shut off all non-essential electricity for one hour and think about their commitment to climate action for the year ahead. This annual symbolic event, draws attention to climate change, carbon emissions, electricity consumption and the impact our actions are having on our planet. The event has grown over the last decade to include a record-breaking 178 countries this year, on six continents and in 24 time zones. Earth Hour is sponsored by the World Wildlife Federation here in Canada, with dozens of municipalities participating. The City of Montreal will turn off the lights in all the main administrative buildings, including city hall, as well as the cross atop Mount Royal, at 8:30pm Saturday night.
|After very mild weather and thunderstorms on Thursday, Montreal awoke to a blanket of snow this morning. (ValleyWX)|
We had a wild few hours of weather in Montreal Thursday afternoon. Rare March thunderstorms swept across southern Quebec between 3 and 5pm, with small hail, strong winds and heavy rain. Overnight, another cold front crossed the region, with light rain changing to snow around 3am. We had a good 2-3cm of snow here on L'Ile Perrot this morning, but it is now in the process of melting. This weekend will be chilly, with mostly sunny skies and highs near 0C (32F). Overnight lows will be cold, down to -10C (14F). Late Sunday, low pressure is forecast to develop near Cape Hatteras, North Carolina and move northeast along the eastern seaboard. Forecast models have been all over the place, with the track of this particular system varying from a complete miss to significant snow as far west as Montreal. We will have to keep an eye on this storm, but at this time, my feeling is that we will get just a few flurries and gusty northeast winds late Sunday and Monday, with not much more for southern Quebec.

Despite Sunday being the first day of spring, a strong ocean storm is forecast to develop along the US east coast by late Saturday and move towards Atlantic Canada by Monday morning. At this time, it looks like Montreal will remain on the western edge of the system, but it bears watching. Measurable snow is possible from the Eastern Townships into New England, with cold northeast winds and a few flurries in Montreal by Sunday night and Monday. A major snowstorm is quite likely for portions of eastern Quebec into New Brunswick and PEI.

|Expect an unsettled weather week in Montreal with plenty of clouds and showers. The silver lining will be mild temperatures along with melting snow. (AccuWeather Photo)|
Showers will prevail for most of the week, as the region is influenced by several areas of low pressure. Much colder temperatures will begin to filter into western Canada, and eventually the Great Lakes, by the end of the week. Until then, expect daily highs either side of 10C (50F) through Friday in Montreal, southern Quebec and eastern Ontario. Colder weather early next week may increase the possibility of some snow in Quebec and New England, but we are still a week out and the forecast may change. Leave the snow tires on for now.

|An early and warm spring may be on tap. It is looking like the entire month of March may remain above freezing for daytime highs in Montreal.|
Stay OFF the ice
On Friday, skies will clear out with mild temperatures returning. The high temperatures will range from 5C to 11C (41 to 52F) most of the weekend across southern Quebec. It should remain dry through Sunday. An important note on this mild weather; All ice on area rivers and lakes is very unstable and thus extremely unsafe to be on at this time. On Wednesday, another drowning occurred after a man fell through the ice while fishing on Shelburne Pond in Vermont.
It was very warm just to our south on Wednesday. While Montreal managed 11C (52F) at Trudeau Airport, I recorded 13C (55F) here on L'Ile Perrot. The high reached 20C (68F) in Toronto, a record-breaking 21C (69F) in Burlington, Vermont and a downright hot 27C (81F) in Albany, New York.

|A surge in warmth this week will give southern Ontario and Quebec high temperatures from 10 to 15C (50 to 60F) by Wednesday.|
|Despite the surprise heavy wet snow Monday morning in Montreal, it looks like much warmer weather will arrive very soon.|
As far as temperatures go, this is where we really see just how warm this winter turned out. The average daily temperature for December through February in Montreal was -3.4C (25.8F), while it should have been closer to -8.4C (16.8F). Those numbers represent a tremendous seasonal difference. You may recall a record 17C (63F) on Christmas Eve, as well as several record highs in January. That being said, I still have lots of ice and snow in my yard, which tends to keep temperatures down, so any real surge in warmth will have to eat away at that before we see true spring weather.
This week will feature typical March weather for southern Quebec, as we start the week with snow, warm up to above 10C (50F) on Wednesday, and then possibly have more snow Thursday night. In general, as we look ahead throughout the month of March, I see milder-than-normal weather prevailing, with lots of above-freezing temperatures expected. A slight dip in the mercury around the 24th may allow for one last sneaky snowstorm. Time will tell, but it really looks like spring is on the horizon.

Where the Quebec Weather Centre made a big mistake on this particular system was upgrading its status to a blizzard. A blizzard is the worst type of winter storm, very few achieve this status, and this system was never that strong from the onset. At best, marginal blizzard conditions might have occurred for an hour or two in the dead of night, and a winter storm warning would have covered that scenario just fine. All the neighbouring weather offices chose to use that type of warning to cover this storm. I have been writing and following weather in the St. Lawrence Valley since I was 12, which would date back to 1978. In all those years, I don't recall Environment Canada here in Quebec issuing a blizzard warning regarding any potential snowstorm.
In any event, milder weather is on the horizon and Spring is close at hand. If you believe the extended forecast, it looks like an early, very warm spring, starting as soon as next week.

|A blizzard warning is in effect for metro Montreal as strong low pressure moves from the lower Great Lakes into New York.|
A rarely-issued blizzard warning has been posted or tonight for southern Quebec, primarily the St. Lawrence Valley including Montreal. Environment Canada defines a blizzard as four or more hours of heavy falling or blowing snow, 40km/h winds or higher, cold temperatures of -10C (14F) or lower and visibility of less than 400 metres (0.4km). I can't recall a blizzard warning being issued for Montreal in recent years, and that includes some substantial storms. I don't think this system will be epic, but it will certainly be challenging for anybody traveling overnight from Quebec City into southern Ontario.
March certainly came in like a lion, with wild weather over the last 24 hours. After several hours of freezing rain Monday morning, a powerful arctic front raced through the city last night. The front was accompanied by thunder and lightning, as well as brief, heavy snow and 80km/h winds in Montreal. In its wake, we have a very cold but calm morning, with a temperature of -15C (5F).
Today will be fair, with increasing clouds and a high near -10C (14F). Tonight, snow will develop, becoming heavy after midnight, along with increasing northeast winds up to 70km/h and cold temperatures near -10C. Widespread blowing snow will reduce visibility to under 0.5km at times. Snow accumulations in the city should range from 10-20cm overnight, with storm totals near 30cm by the time precipitation ends early Wednesday afternoon. Low pressure will move from the Ohio Valley just south of Montreal and into Maine Wednesday. Winter storm warnings are also in effect down the St. Lawrence River towards Kingston and west into Toronto. Travel along the 401 corridor will be very difficult starting today through early Wednesday. Heavy snow is also expected north of Montreal. More than 30cm is forecast from the Ottawa Valley across the Laurentians.
