Will March come in lamb or lion like?
WARMING TREND?
So the question of the week, and stated here in much more polite terms that is has been poised to me, when will it warm up? The answer, soon, but very slowly. It is a valid question given that this is one of the longest below 0C (32F) periods in recent memory. The temperature dropped below 0C in Montreal at 1pm on January 19, 2015, by my calculations very close to 40 days ago. It has not risen above since. The average temperature for February so far is in the -15C (5F) range with a day to go, which puts it on par to be one of the coldest months ever in this city. If we look even further back into the record books, 56 of the last 59 days have been below freezing making it one of the most prolonged cold spells since the early 1900's in Montreal.
WEEKEND FORECAST
Sunshine will prevail today across the St. Lawrence Valley but with cold highs of around -10C (14F). On the weekend it will turn warmer with highs forecast to be around -4C (25F) both Saturday and Sunday. Overnight lows will remain chilly, down to -18C (0F). Late in the day Sunday clouds will increase from a weak frontal system, with some light snow overnight into Monday. Amounts will range from 3-10cm across the area with the highest amounts in the Adirondacks and Green Mountains. Sunshine returns Monday into Tuesday before another low pressure area approaches form the Great Lakes. At this time it looks like snow will develop late Tuesday night in Montreal and persist into Wednesday, perhaps mixing with rain. Yes I said rain, and that means our streak of below freezing weather could come to an end as early as next Wednesday. Amounts of precipitation with this storm will be in the moderate range, perhaps more than 10cm (4 inches of snow), then rain or freezing rain, so perhaps warnings will be required. It is still early in the forecast period, so we will have to wait and see how this system evolves.

Very slow warming trend for Montreal
Above & Below: Just how cold has it been? Enough to partially freeze over the mighty Niagara Falls. |
WARMING TREND?
I may have been a little too excited this morning in my claim that Montreal would not see anymore minus 20 degree mornings. In fact the cold front that crosses the region tomorrow night will introduce a reinforcing shot of cold air. With clear skies tomorrow and again Thursday and Friday we may indeed dip just below -20C in some parts of southern Quebec. The good news is we are looking at a general warming trend into the weekend and next week. It won't become tropical, but temperatures will get closer to the normal high and low of -2C and -11C respectively. What I do however see for March is snow, and perhaps lots of it. Montreal has really managed to avoid a major snowstorm this year with a generous 20cm recorded on two occasions. That may change as we head into March and the storm track begins to originate more from the Gulf of Mexico and travels a little further north along the jet stream. Time will tell, but that is what the crystal ball is showing right now.
GREAT LAKES ICE
Incidentally the Great Lakes have more ice cover than last year at this time. Just over 84% of the lake area is covered with ice, way ahead of last year which was 67% at this time. In 40 years of record keeping, the maximum recorded ice was in the cold winter of 1979 with 97%. Last year the maximum of 92.5% was reached in March. Even the mighty Niagara Falls have been slowed somewhat as large portions of it are frozen over. The vast ice cover will likely have an impact on our spring, just as it did last year.

One more week of the arctic chill for Ontario & Quebec
The cold will last all week with a forecast high of only -18C (0F) today for Montreal, dropping into the mid minus 20's overnight region wide. Tuesday clouds will increase as a weak clipper moves in from western Canada. That will moderate temperatures slightly, rising up to between -7C and -9C (15 to 20F) for the balance of the week. While that is still well below normal, it is a vast improvement over the rest of this month. Lows will be in the -15 to -17C (2 to 5F) range. As far as snowfall goes, we are expecting at 2-5cm late Tuesday and Wednesday before high pressure returns on Thursday. Skies will remain clear into next weekend with moderating temperatures. At this time the start of March looks stormy, but that is still a week away. As we have seen this winter, allot can happen in that time frame.

24 hour break from the cold for Montreal
Frozen in time...Belgrave Avenue in NDG on Friday morning. (Global News Photo) |
Clouds have increased again over southern Quebec this morning in advance of low pressure moving from the Ohio Valley down the St. Lawrence Valley. Light snow will start early today and taper off by Sunday morning. A general 5-10cm (2-4 inches) is forecast across southern Quebec and Ontario with perhaps 15-20cm (6-8 inches) along the US border and points south into the Greens and Adirondacks. Temperatures will warm all day today, tonight and Sunday up to a sultry -2C (28F). It may even rise above freezing in a few spots Sunday, which would be the first time that has happened in over 6 weeks. It will be short lived as winds will increase again late Sunday and temperatures will plummet down to -20C (-4F) in Montreal by Monday morning. Clouds and flurries are likely along an arctic front that will clear the region by Monday morning. The high on Monday will only be -17C (2F) with gusty winds and low windchill values. The gusty 50km/h winds will also blow around the fresh snow once again making travel poor on highways outside the city.
The prolonged frigid weather has created a mess with multiple water main breaks in Montreal. There have been several major breaks across the island that have flooded basements and trapped cars in mounds of ice. Yesterday was no different with a break on Belgrave Avenue in NDG not only flooding roads, but also the AMT commuter rail line, delaying service for the third time this week. The delay in train service left thousands of commuters freezing on windy platforms on three lines. Earlier in the week, frozen switches delayed train service for over an hour Thursday night.
No major relief is in sight yet with more cold weather all this week.

It could be the coldest February in Montreal since 1978
Brackley Beach, PEI buried under record snows. |
We have not had lots of snow this month, but what has fallen has stayed and is piled high everywhere. It is no coincidence that Boston is having a winter that is rivaling that of 1978. The two winters have strong similarities, and we are not done yet.
The next storm poised to bring snow to New England, Quebec, Ontario and Atlantic Canada this weekend. |

Powerful winter storm slams Atlantic Canada

Heavy snow with strong winds in excess of 100km/h brought travel to a standstill, even keeping the snowplows off the roads in parts of New Brunswick and Nova Scotia. Nearly 50cm of snow fell in Greenwood, Nova Scotia, with 43cm at Moncton. In Halifax, the heavy snow was followed by a brief warm up and over 20mm of rain. The rain and melting snow flooded streets which rapidly froze when the temperature fell from plus 2C (36F) to -6C (21F) in one hour this afternoon. Strong winds in excess of 70km/h also hit Halifax. Charlottetown, PEI has received over 60cm of snow with 95km/h winds and visibility under 1km for over 24 hours. The Gaspe coast of Quebec was also hit with blizzard conditions, and up to 40cm of snow. Widespread travel disruptions and power failures stretch across Atlantic Canada and into eastern New England. Boston has now had its third snowiest winter on record reaching 89.2 inches of snow on Sunday as another 10 inches fell by late in the day. More snow is forecast by Wednesday as another storm moves up the eastern seaboard.

Frigid with blowing snow advisory for southern Quebec
Low pressure is diving southeast across the Great Lakes today and will move towards Cape Cod tonight. This storm will then deepen rapidly into a major Nor'easter as it moves along the coast and into Nova Scotia. A very tight pressure gradient on the west side of the storm will increase winds across the Great Lakes basin and St. Lawrence Valley late today and Sunday. Winds in excess of 60km/h are likely in Montreal with higher gusts along the waterways. The result will be widespread blowing snow late this afternoon, overnight and early Sunday. Environment Canada has posted a blowing snow advisory for metro Montreal and points south with visibility expected to be under 1km at times. Travel with caution later today, especially outside the city going south.
As far as accumulations go, Montreal will be on the edge of the precipitation shield with perhaps 5-10cm (2-4 inches) of snow over the next 24 hours. The northwest wind will also pull down bitterly cold air with readings around -18C (0F) today and Sunday and windchill readings in the minus 30's. Lows Sunday night may be the coldest of the season, down to -25C with windchill values approaching -40C in southern Quebec and Ontario. The same forecast holds true for New York and New England with more snow forecast in those regions. A vast amount of warnings are in effect from the Ohio Valley across southern Ontario and Quebec, New England and into Atlantic Canada. Snowfall will range form 10-40cm across those regions. Winds will gust to hurricane force along the New England coast and into the Maritimes. Coastal flooding is possible in many communities. Around the Great Lakes snow squalls will affect the area south of Georgian Bay and Lake Huron as well as western New York as the cold air surges in. The Nor'Easter will pull away into Newfoundland by Monday with diminishing winds and very cold temperatures in its wake across Quebec.

Windy, bitterly cold weekend for Quebec & Ontario
ANOTHER BOSTON BLIZZARD
Another clipper low will dive across Lake Ontario tonight and Saturday with another period of snow and blowing snow for southern Ontario and Quebec. A general 5-7cm is likely, very similar to Thursdays system. As that low reaches the Gulf of Maine it will bomb out becoming a major storm. Eastern New England, including Boston, and Atlantic Canada will see blizzard conditions on Sunday with heavy snow, over 30cm (1 foot) and winds in excess of 100km/h. Coastal flooding is possible from Massachusetts into Nova Scotia. The storm will also pull down very cold air across Quebec. Temperatures this weekend will be frigid around -16C (4F) for highs in Montreal with very strong winds all weekend. Montreal will remain on the edge of the coastal storm with clearing skies on Sunday but windy and cold. No warm air is on the horizon through at least the middle portion of next week.

Another arctic outbreak forecast for Montreal
This pattern by the way, shows no signs of changing in the near future. L'Ile Perrot is clear this morning at -17C (2F), another cold morning, well below the normal low of -13C (9F). The high today is forecast to be only -13C (9F), the normal high is -4C (25F) for Montreal. Clouds will increase this evening as another clipper type low pressure system, following the same track as the last few, moves south of Montreal across New England. Snow will develop in Ottawa this evening and Montreal after midnight with 5-10cm forecast through Thursday. Temperatures will moderate slightly in the snow but then plummet Thursday night and remain frigid into this weekend. Lows overnight both Saturday and Sunday will be near -24C (-11F) in Montreal and even colder in rural areas away form the city. Strong winds will make the windchill bitter. After the snow Thursday, no major storms are forecast for Montreal at this time.
RECORD BREAKING SNOW FOR BOSTON
The big weather news this week has been the relentless parade of storms across New England. More heavy snow this week in Boston and southern coastal New Hampshire, has pushed the three week total to over 70 inches (175cm). It also has placed this winter`s snow depth at number nine all time in Boston, and climbing up quickly. More heavy snow is forecast this weekend with the potential of two separate storms impacting the region. Snow is piled up to the roof tops in some places. The National Guard has been called in to help with snow clearing operations. Some roofs have even collapsed under the weight of the heavy snow. It has snowed in Boston on 13 of the last 17 days.

Below normal temperatures for Montreal

Montreal will see just a few flurries today, with little additional accumulation expected. Gusty northeast winds will persist. On Sunday the wind reached as high as 60km/h, and combined with the cold and snow, made for terrible road conditions. Numerous accidents were reported again, including a major one on the South Shore near Drummondville. The wind also made it feel as cold as -30C (-22F) in Montreal. Today will be no different with the high struggling to reach -13C (9F) along with a 50km/h wind. It will warm slightly for Tuesday and Wednesday, up to -8C (18F) or so, but another round of snow is on the way for mid-week. A clipper system will follow the same track across the Great Lakes and New England giving Montreal and southern Quebec another 5-10cm of snow late Wednesday into Thursday. Once that system clears the region Friday, strong north winds and bitter cold will arrive with some of the coldest air of the winter expected. Highs will be near -18C (0F) with lows as cold as -25C (-13F). It will at least be sunny next weekend.

Lond duration period of snow forecast for Montreal
More snow is forecast for the winter weary east this weekend. (AccuWeather) |
A frontal boundary will establish itself across southern New England separating the polar air over our region from the more March like warmth creeping into the southern US. The warm air rising over the cold air at the surface will generate precipitation in the form of snow across interior New England, southern Quebec and eastern Ontario. Flurries are expected today, before a general light snow starts late Saturday. On Sunday a period of steady snow is expected, with up to 10cm possible by Monday afternoon for Montreal. Accumulations may reach 15cm or more over New Engalnd. The good news is that temperatures will moderate from the frigid low of -26C (-15F) this morning on L'Ile Perrot up to -10C (14F) today. Highs this weekend will be around -8C (18F). More arctic air is poised to invade Ontario and Quebec next week with very cold temperatures expected by Wednesday night. No real warming trend is anywhere in sight at this time, just more periods of snow and cold as the weather pattern remains active.

Relentless snow & cold to continue
Moncton, New Brunswick on Tuesday. (CBC Kate Lerrerick) |
Snow has pounded New England and Atlantic Canada once again with over 30cm (1 foot) in parts of New Brunswick, PEI and Nova Scotia on Tuesday, adding up to over 100cm in the last two weeks. A state of emergency was declared in St John after 91cm of snow. Winds in excess of 150km/h produced blizzard conditions in western Newfoundland on Tuesday as well. A rapid freeze occurred in Newfoundland with snow changing to rain or freezing rain and then back to snow in a matter of hours. In Boston, the city has set a record for the most snow in a seven day period with 40.2 inches, this after another 16 inches hit that city Monday. More snow is forecast Thursday for New England and the Maritimes with winter storm warnings now posted for Nova Scotia and New Brunswick.

Welcome to the 33rd day of January
It was a painfully slow commute to and from work in Montreal on Monday. Expect more of the same today as the extreme cold has made salt ineffective. (ValleyWX Photo) |
Different month, same weather for southern Quebec. My drive into work and home on Monday was possibly the worst commute I have had this winter. Snow and extreme cold is making salt ineffective. Roads were snow packed and extremely icy, and that has lead to hundreds of accidents as drivers refuse to slow down. In one split second on Monday on Highway 20 near Beaconsfield, two SUV's spun out in front and immediately behind me, hitting the guard rail in the process. It was icy, and the vehicle behind me in particular was travelling too fast for the conditions. The same holds true this morning with icy roads and many accidents in metro Montreal.
Around 10cm of snow fell in Montreal on Monday, driven by winds in excess of 50km/h most of the day. It was cold with a high of only -17C (1F) and bitter windchill values. We currently sit at -24C (-11F) in Montreal with lighter winds thankfully. It will be sunny today and a little milder with highs to -12C (10F) by late in the day. Clouds will be on the increase as another clipper type low pressure area arrives from western Canada. Snow will develop tonight and last into Wednesday with another 5-10cm possible for eastern Ontario and southern Quebec. Temperatures will be much milder on Wednesday in the snow, up to a balmy -6C (21F). It will turn colder again on Thursday with more snow likely by Saturday for Montreal.

Six more weeks of winter - starting today!
Phil in Punxsutawney, Pennsylvania at 7:20 AM this morning. Phil saw his shadow, 6 more weeks of winter, as if we did not already know! |
As I write the various groundhogs across North America are getting ready to make their fearless prediction for an early Spring or six more weeks of winter. I just had to ask my dog, she did not want to walk this morning, and for good reason. It is a frigid Monday morning in Montreal and across the entire region. The temperature is currently -22C (-8F) with a wind blowing out of the northeast, as it will be all day, in excess of 50km/h. Add the two and you are looking at windchill readings in the minus 30's.
Strong low pressure that has put down 1-2 feet of wind driven snow from Illinois into Michigan and Ontario is edging into southern Quebec this morning. The center of the low will move across Pennsylvania and off the Atlantic Coast near New York City by tonight.We will remain on the northern edge of the precipitation with 10cm of snow for Montreal and up to 20cm along the US border. 20-30cm is forecast for snow weary New England and Atlantic Canada. The wind will be a major factor in Montreal as it has been along the entire 401 corridor. Expect lots of blowing snow with visibility often under 1km. A blowing snow advisory is in effect for the St. Lawrence Valley, with winter storm warnings for the Townships where 20cm is forecast today. Travel by air and road has been greatly impacted across Ontario and the US Midwest and expect delays in New England and Quebec today. Call ahead to the airport as many flights to Toronto have been delayed. Already 15-20cm has fallen in Toronto with 35cm (14") in Windsor, Ontario and Detroit, and 19.3 inches in Chicago.

Groundhog Day storm to shift north - affect Montreal
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.
