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!

Mini storm for Montreal, Ontario & Quebec
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.
The Details...
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.

Strong winds in Montreal - little snow from big nor'easter
No cars and no snow for the Big Apple this morning. (Sun Sentinel) |
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.

Historic storm to hammer east coast & brush Montreal
Long Island Expressway in New York this afternoon (via Twitter WPXI) |
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.
Wicked winter storm to pound New England - miss Montreal
Once again Montreal 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.

New storm threatens east coast - Montreal on western edge
A major storm will impact New England and eastern Canada this week. (AccuWeather) |
Montreal will remain right on the edge of the precipitation shield with perhaps 5cm of snow on Tuesday. It will be windy and cold. |
A new clipper-type low pressure system will be moving from the Prairies across the Ohio Valley on Monday and off the coast of Virginia by late in the day. It will then strengthen and is forecast to become a powerful Nor'Easter that will make news as it moves towards Nova Scotia by Wednesday. Just 36 hours ago the models had this storm system passing well out to sea. But now it is expected to move much closer to the coast and provide all of New England and eastern Canada with a major storm. Some portions of the coastal regions from New York to Atlantic Canada could see 30-60cm (1-2 feet) of snow. Winds are forecast to howl over 100km/h (60 mph) with the snow on Tuesday causing blizzard conditions in Boston and New York City. High surf may cause coastal flooding for New England and Nova Scotia. This storm will be strengthening as it slowly moves northeast along the coast. Winds are forecast to increase out of the northeast on Tuesday in Montreal (over 50km/h) and the rest of southern Quebec as well. We can now expect some snow on Tuesday, but the bulk of the accumulations will be well south and east of Montreal. I expect perhaps 5cm (2 inches) for Montreal, more for the Townships and Quebec City, but this will have to be watched closely as there remains much uncertainty with the exact track. Travel will be very difficult to impossible in eastern Quebec, New Brunswick, P.E.I, portions of Nova Scotia as well as New England, so if you have plans Tuesday pay close attention to later forecasts. So far in our region, a Winter Storm Watch is in effect for southern Vermont as well as a Special Weather Statement for Atlantic Canada.

Another coastal miss for Montreal - cold week ahead
Heavy snow is falling this morning from New Jersey (above) into coastal New England. For many it i the first snow of the season.(Photo via Twitter @justinhfd126) |
MONTREAL WEATHER
Meanwhile an arctic cold front will bring an end to the mild temperatures in Ontario and Quebec. Montreal was 0C (32F) Friday and can expect a high of -1C (30F) today under cloudy skies. The cold front will cross the region late this afternoon and this evening with some light snow possible. At best 1-3cm may fall locally across southern Quebec and eastern Ontario. Temperatures will fall quickly overnight under gusty northwest winds of 20-40km/h, down to -14C (7F), along with cold wind chill values. Sunshine returns Sunday, but it will be breezy and cold. For most of this upcoming week arctic high pressure remains in control, temperatures will be cold with lows around -18C (0F) and highs no better than -10C (14F). The next chance for snow in Montreal will come along yet another arctic front late in the week.

Calm weather for Montreal - fierce storm hits Labrador
Heavy snow buried Labrador City and Wabush Tuesday and Wednesday halting all travel. (The Weather Network) |
A winter storm will affect New York and Boston this weekend northeast into Atlantic Canada, but miss southern Quebec. |
Labrador Blizzard
The storm that affected southern Quebec on Monday with snow and rain strengthened and brought a fierce winter storm to Labrador and western Newfoundland. Nearly 80cm of snow fell in Wabush with businesses and schools closed across western Labrador. Travel and any form of transportation was nearly impossible with winds gusting over 70km/h. Temperatures are frigid behind the storm with -43C this morning in Labrador City. The region now has over 150cm (60 inches) of snow on the ground in many places. Roads between Wabush and Churchill Falls were closed Tuesday but reopened Wednesday despite less than ideal conditions. It will remain frigid this weekend.

Clear & cold week ahead for southern Quebec
January is one tough month to get through, very ironic as we start the new year with so much hope and energy. Truth is, here in Montreal at least, it is a dark, windy and cold month. This month for example we have only been above freezing on two days, both those days had stormy weather to compensate for the warmth. It is cold again this morning, currently at -19C (-2F) at my home on L'Ile Perrot, with clear skies but a gusty northwest winds making it feel more like -28C. It will not warm much today, perhaps -13C or so by late this afternoon. Another cold night tonight with a forecast low of -18C. The rest of the week looks tranquil with the next chance of precipitation coming from a weak system Saturday. No big storms on the horizon, just seasonal cold and typical January weather.
Carnage on Northeast Roads
The winter storm over the weekend proved not to be a strong as originally thought. Montreal had between 5-10cm of snow, depending where you were in the metro area. Other regions had between 10-20cm of snow with the most falling over the Green Mountains of Vermont as well as northeast of Quebec City and in Labrador. The big news form this weekends storm is how deadly it turned on Northeast U.S. and New England highways. Light rain onto very cold highways produced black ice Sunday morning. Thousands of accidents were reported from Pennsylvania into Vermont with 9 fatalities and scores of injuries. Many highways were closed including major interstates. Two of the deaths occurred just outside Burlington, Vermont on Monday morning. Others occurred in two separate pile ups in eastern Pennsylvania on Sunday. Black ice as well as excessive speed were reported as the cause of most accidents. I hate freezing rain, it just plain scares me, and not too much does, it is unforgiving. The best advice always is just stay home or delay your departure if at all possible.
Just one example of the thousands of accidents that occured Sunday and early Monday on New England and Northeast US highways due to ice. |

Montreal on the western edge of east coast storm
Mild temperatures today made for a perfect day outdoors at Cap St. Jacques nature park on the West Island of Montreal. (ValleyWX Photo) |
A mix of rain, freezing rain and wet snow is likely tonight across southern Quebec, with the heaviest precipitation falling across the Townships, north and east into Quebec City and central Quebec. My initial forecast last Thursday of 10-15cm for Montreal still looks good. Upwards of 20cm or more is possible for Quebec City, and portions of central Quebec may see as much as 50cm. Freezing rain will be a problem tonight in many regions of southern Quebec as it has been across New England today. Drive with great caution and expect slick roads everywhere. Rain is falling in the Townships, but that will change to snow tonight. The snow will taper off from west to east by late Monday. Temperatures will drop Monday in Montreal down to -5C by late in the day. Strong gusty winds up to 50km/h will cause some blowing and drifting snow.
Current Warnings:
Winter Storm Warning: Quebec City, North Central & Northeast Vermont.
Winter Weather Advisory: Champlain Valley of NY & Vermont.
Rainfall Warning: Eastern Townships

Storm forecast a tricky one for Montreal
Lakeshore Drive in Dorval on Friday. Another messy and slow January commute in Montreal. (ValleyWX Photo) |
So far a Winter Storm Watch has been posted for the Champlain Valley and Vermont with a special weather statement for the Townships. Please keep in mind this forecast is a challenging one with several different scenarios being presented by the forecast models. I will monitor the forecasts and data and provide updates all weekend. Stay warm!

Frigid Friday & potential weekend storm for Montreal
A second more potent storm still looks likely late Sunday into Monday for a portion of our area. The models continue to disagree on the track and intensity of the storm, leading to low forecast confidence at this time. It certainly looks like we will see accumulating snow late Sunday into the Monday morning commute in Montreal. At this point amounts and the exact location remain difficult at best. I am watching this closely and will post updates later today. In the meantime stay warm today and drive safe.

Potential storm for Montreal this weekend
POTENTIAL COASTAL STORM
Forecast models are coming into better agreement regarding snow and mixed precipitation this upcoming weekend for portions of southern Quebec and New England. Low pressure along the Gulf Coast will redevelop near the North Carolina and Virginia border Saturday and move northeast into New England by late Sunday. The models have the storm tracking anywhere from Albany towards the immediate coast. The exact track of the low pressure area will determine the type and quantity of precipitation for Montreal. At this time it looks like snow developing Sunday in Montreal and continuing into the evening with more than 15cm (6 inches) possible. Further south and east into the Townships and New England the snow will likely mix with freezing rain and rain. This system will have to be monitored closely as it is expected to have an impact on travel Sunday into Monday. It will turn colder again Monday with flurries and gusty winds behind the storm.

Arctic chill creates icy roads & large demand for hydro
Snow everyday this month along with the recent cold has left large piles of snow around the city. (ValleyWX) |
Ice fog this morning has prompted a special weather statement from Environment Canada indicating that black ice has formed on area bridges and elevated roadways in metro Montreal. This problem should clear by mid-morning as temperatures very slowly warm today under sunshine to -13C (9F). It will be cold again tonight under clear skies, dropping to -20C (-4F). Another cold front will approach Ontario and Quebec late Thursday into Friday with perhaps a few snow showers. It will be relatively mild Thursday up to -10C (14F) and -7C (19F) Friday, but winds will increase making it feel cold and damp outdoors. Saturday looks cold once again before a very mild Sunday but with a chance of snow.

Cold week ahead for Montreal
A weak clipper system will give Montreal 5cm of snow Monday before another surge of arctic air tonight. |

Wild winter weather week
The long and slow Friday morning commute on L'Ile Perrot. Just another day in a week of terrible road conditions in and around metro Montreal. (ValleyWX Photo) |
Frost Quakes
If that was not enough, in the wee hours of Monday morning, I was shaken out of bed at around 2:30am by what I thought was an earthquake. Turns out it was a frost quake or cryoseism. It was heard and felt across the West Island and here on L'Ile Perrot. Frost quakes occur with rapid changes in temperature as well as precipitation seeping into the ground and then freezing quickly as it did last Sunday in Montreal. This puts stress on the surrounding rock until it is released with a loud boom and in some cases even a crack or shake!
Treacherous Roads
The week also featured terrible roads conditions across the Great Lakes region into Ontario, New England and Southern Quebec. Brutal cold, combined with snow squalls iced up roads and cut visibility rapidly. I spent over 12 hours in my car commuting around metro Montreal this week, including two hours Friday morning just to go 28km (17 miles). The weather conditions lead to a rash of major accidents including one yesterday on Interstate 94 near Battle Creek, Michigan. The accident involved more than 150 vehicles with one fatality and 20 injuries. The one death was sadly a truck driver from Quebec. Michigan State Police had to close the highway in both directions for over 14 hours. It was just one example of many that occurred this week.
This morning it is quiet so far in Montreal and chilly at -12C. A few snowflakes are possible all weekend with a chance for accumulating snow Sunday night into Monday morning almost guaranteeing us another slow commute. It will be milder this weekend but turn cold to start next week. You have to love January, but I don't!

Extreme cold invades Montreal, southern Quebec & Ontario
EXTREME COLD WARNING: Extended to metro Montreal as of 8pm.
The coldest air of the season is set to invade southern Quebec and Ontario today behind an arctic cold front this morning. Overnight lake enhanced moisture put down about 5cm (2 inches) of fluffy snow here on L'Ile Perrot, enough to cover up Sunday's ice and make driving treacherous. The Tuesday night commute was much the same in Montreal with ice and narrow lanes due to snowbanks making for a long drive home. The ice and lack of salt has resulted in four times the normal amount of visits to Montreal and area emergency rooms for falls and fractures. In addition there has been a spike in car accidents and calls to 911 for EMS and fire services.
The snow today will taper off by noon with perhaps another couple of centimetres in the most persistent squalls along the cold front. Temperatures are currently at -9C (16F) in Montreal but you do not have to go much further west to find evidence of the advancing cold air and increasing winds. Ottawa is already down to -16C (3F) with a 57km/h wind and a windchill reading of -29C (-20F). We have reached our high temperatures for today in Montreal with the mercury expected to tumble the rest of the day down to -25C (-13F) tonight. We may challenge the coldest temperature of the last two years here on L'Ile Perrot which was -27.3 (-17F), Januray 2, 2014. Winds will increase out of the northwest at 30-50km/h with windchill values in the minus 30's tonight. An extreme cold warning is in effect for most of Ontario and Quebec but excludes metro Montreal. Again we are splitting hairs with the warning criteria, bottom line is it will be dangerously cold today through Thursday. The high Thursday will eventually be around -13C by late in the day. Slightly milder air by Friday up to -10C but with more light snow.
The cold air rushing across the Great Lakes is producing major snow squalls in Ontario off Lake Huron as well as New York off Lakes Erie and Ontario. Highway 402 through London to Sarnia will be a focal point today for heavy snow, strong winds and dangerous cold. The same applies to portions of Interstate 81 from the Thousand Islands to Syracuse.

We are left this morning in Montreal with lots and lots of thick ice as well as brutal cold, -13C (9F) with a 60km/h wind and a windchill of -25C (-13F). Ottawa is at -17C (2F) with a windchill of -29C (-20F). It is cold and will stay that way throughout the week. Two clipper systems will bring us flurries (1-3cm) Wednesday and Friday with reinforcing shots of arctic air behind them. Winds will be gusty all week creating dangerous windchill values. Temperatures will be in the minus teens for highs and -20's for lows.

Icy Sunday in Montreal to be followed by brutal cold
Lots of ice in Montreal after 12 hours of freezing rain. |
The winter storm affecting Ontario east towards Atlantic Canada continues this morning in southern Quebec. As I expected the warm air aloft is having a very difficult time making it to the surface in the St. Lawrence Valley. While temperatures are at or above freezing just to the south of Montreal along the U.S. border, it remains a cold -5C (23F) here in the city. As a result sleet and freezing rain have been falling for the last several hours. This, after between 15-20cm of snow in the Montreal region. Roads are slushy to snow covered with plenty of ice around resulting in numerous accidents being reported by city and provincial police over the last 12 hours. Precipitation has changed over to rain south of Montreal and should do so in the city by noon. Precipitation will likely remain as freezing rain for the Ottawa Valley. Temperatures will slowly rise to around plus 4C (39F) today in Montreal before an arctic cold front arrives this evening. That front will produce flurries and strong winds between 40-70km/h as well as rapidly dropping temperatures. The mercury will fall down to -10C (14F) by morning and -17C (2F) by late in the day Monday for Montreal as well as Ottawa and eastern Ontario.
The clean up as started, pushing away the 15-20cm (6-8 inches) of snow that fell overnight across the Montreal region. Freezing rain occurring now will change to rain by noon. (ValleyWX) |

Winter Storm Warning for Montreal
WINTER STORM WARNING:
Eastern Ontario and Southern Quebec including Montreal and Ottawa. The winter storm warning has been posted for all of southern Quebec as well as the Ottawa Valley with 15-25cm (6-10 inches) of snow expected before the transition to freezing rain.
Snow has overspread southern Quebec and Eastern Ontario late this afternoon and will continue until well after midnight. The intensity has been light so far but it will become heavy as the evening progresses. A large area of moisture is moving northeast ahead of a warm front lifting across the Ohio Valley and into New York. Low pressure deepening across the Midwest will move into the Great Lakes and down the St. Lawrence Valley Sunday. Heavy snow with blowing snow tonight will mix with freezing rain overnight and eventually change to rain in Montreal and points south on Sunday. Temperatures are very cold right now in Montreal at -12C (10F) with an increasing northeast wind. The mercury will attempt to warm to the freezing point by Sunday morning and up to 5C (41F) during the day. Any rain will change back to flurries late Sunday as an arctic front crosses the region with plummeting temperatures to -11 (9F) by Monday morning. Winds will also increase tonight up to 50km/h and eventually 70km/h on Sunday.
In southern Ontario the snow has already changed to rain and freezing rain in Toronto with a current temperature of 0C (32F).
Next week will be cold with flurries. The coldest air of the season arrives by Thursday with lows in the minus 20's and daytime highs near -20C. Windchill values will also be very low.

Winter storm to impact Montreal this weekend
A rather cold air mass has settled into southern Quebec this morning after a few centimeters of snow on New Years Day. The snow was thanks to a rather vigorous lake effect snow band that drifted down the St. Lawrence Valley. That snow band was responsible for very poor travel conditions along the 401 from Montreal to Trenton. Numerous accidents, including a multi-vehicle pile up near Odessa, closed the highway for a period yesterday. Today there will be a break for Ontario and Quebec between two weather systems. Sunshine will prevail, but it is breezy and cold, currently at -10C (14F) in Montreal with a windchill of -16C (3F). We may gain a degree or two today but not much more than that.
FIRST STORM OF 2015
Our attention then turns to developing low pressure area over the southwest US. This system brought snow and strong winds as well as freezing rain to portions of Arizona, Nevada, California, Texas and Oklahoma. It managed to snow in Las Vegas on New Years Eve! The storm will deepen as it moves towards the Great Lakes on Saturday with a wide swath of moisture moving into Ontario and Quebec. With cold air firmly in place in Montreal and Ottawa look for snow to start with perhaps as much as 15cm (6 inches) from late Saturday into the wee hours Sunday morning. Much warmer air surging north on the east side of the storm will change precipitation over to freezing rain and eventually rain for a period on Sunday close to Ottawa, the St. Lawrence River and points south. Temperatures will be very cold Saturday, near -10C (14F) in Montreal but warm, according to Environment Canada, to 10C (50F) on Sunday. I think this is very generous given the history of the valley to hold onto cold air. It will rise above freezing Sunday and precipitation will change to rain, but I don't think we will see 10C (50F). Perhaps 5C (41F) may be more close to reality. But admittedly, I am no expert. Precipitation will taper to flurries on Sunday night as temperatures start to fall rapidly to -10C by Monday morning. Another factor with this storm will be strong winds as the storm continues to deepen over northern Quebec. Winds will increase Sunday up to 50 to 80km/h.
Next week look for the coldest air of the season to arrive by the middle of the week with temperatures down to -20C (-4F) or colder by Thursday morning. The cold air will be with us all week once this storm passes.

A lifelong passion for the weather enters 35th year
The methods of gathering and processing data have changed so much in the last 35 years, but the science remains the same. I have gone from plastic thermometers and rain gauges to a sophisticated Davis Weather Station in my back yard that sends 24 hour data directly to my computer and the web.
I appreciate everyone who reads, sends comments or just chats with me about the weather in person, through the blog or via twitter. I am always available to talk weather! Let's see what adventures year 35 holds in the weather department. With our climate changing so dramatically in the last 20 years, you never know what to expect.
