Montreal received about 25mm of rain over the last week to bring our monthly total to only 59.2mm (2.2 inches). That amount fell on only 6 days of the month. We normally have precipitation on 13 days during March. The incredible stats are our daily maximum temperatures and snowfall. The average maximum was 7.7C compared to a normal of 2.2C. The mean average was a warm 3.3 compared to the normal of -2.3C. We recorded only 1.4cm of snow officially at Dorval, or less than one inch. Unbelievable for a "winter" month. We are looking at potential record highs on both Friday and Saturday with temperatures reaching 25C.

Flooding continues to be a major issue from New Hampshire across Massachusetts and southern Connecticut and into new jersey and New York. parts of New jersey are experiencing the worst flooding in over 25 years. In Massachusetts the Governor has declared a state of emergency, and the National Guard has been called out.
After the rain tapers off late Wednesday, skies will clear out under strong high pressure, and record setting warmth and sunshine will move into the east for the Easter long weekend. Look for sunshine and temperatures approaching June values from 24 to 27C.

The good news is that once the rain moves out by Wednesday, we can expect a large ridge of high pressure to build in from the central US. A bubble of warm, summer like air will arrive just in time for the long Easter weekend. I expect sunshine Friday and Saturday with temperatures over 20C.

Earth Hour occurs tomorrow night at 8:30pm local time. You are asked to shut down all lights for one hour to help save the earth and our environment. Earth Hour started in 2007 in Sydney, Australia when 2.2 million homes and businesses turned their lights off for one hour to make their stand against climate change. One year later Earth Hour had become a global sustainability movement with more than 50 million people across 35 countries participating. Global landmarks such as the, Sydney Harbour Bridge, The Cross on Mt. Royal here in Montreal, The CN Tower in Toronto, The Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.

Our roller coaster weather week continues along, with the greatest dip poised for tonight in Montreal and Ottawa and across the region. Yesterday Montreal reached 11C after a morning start with sub-zero temperatures and snow cover. The afternoon sun was warm and temperatures rebounded to well above normal. Today will be sunny and very warm once again on increasing southwest winds in advance of an arctic boundary. That front will cross the St. Lawrence Valley by 8pm this evening with showers and some snow squalls along it and a dramatic drop in temperatures. In a month that has been above normal almost everyday along with no sub-zero highs (very rare for March), tonight and tomorrow will feel frigid. The front will drop temperatures from today's high of plus 12C down to -10 to -13C overnight, a swing of almost 25 degrees. Along with the cold Arctic air will be strong winds from the southwest, backing to the northwest tonight and gusting to 50km/h producing noticeable wind chills. Any precipitation will freeze on area roads so keep this in mind while traveling. Friday will be sunny, but very cold, and perhaps our fist below freezing high for the month at -2C.
A quick wrap up of Tuesday's storm, it produced about 16mm of rain in Montreal with the heaviest rainfall southeast of the city. Lennoxville had 33mm and parts of Vermont over 50mm. Heavy snow fell north of Quebec City with Le Massif in the Charlevoix region recording 47cm. Winds gusted to 63km/h in Montreal, and 94km/h on Ile d'Orleans near Quebec City.

Low pressure this morning over Pennsylvania will move northeast to near Boston by late today. Radar at 8am (shown above) was showing heavy rain over the Montreal region, it has been falling since about 4am. Winds are gusting out of the northeast to 63km/h at Montreal, and 65km/h at Quebec City. While Montreal is reporting rain at 1C, the northern edge of the precipitation is falling as freezing rain and snow. Mirabel is 0C with freezing rain and Quebec City is -1C with snow. The cold rain, freezing rain and snow will continue all day with 20-40mm of total precipitation expected. Heavy snow is falling north of Quebec City into the Saguenay and Charlevoix regions. Roads are very poor in those areas as well as north of Montreal, where several schools have been closed for the day. Traffic is slow in metro Montreal due to water accumulation on area roadways and reduced visibility in heavy rain.
Weather Warnings are in effect for heavy rain, freezing rain and snow in most regions outside of metro Montreal including Eastern Ontario and the Ottawa Valley. Flood watches have been posted for New York and Vermont. Winds will remain strong today gusting over 60km/h. All precipitation will end overnight tonight as a period of wet snow with 5 to 10cm (2-4 inches) expected in many parts of southern Quebec and eastern Ontario, with a little less in the city.

Low pressure over the Ohio Valley is forecast to move into southern New England by Tuesday morning. A warm front will lift northward to just south of the St. Lawrence Valley overnight. In advance of this storm heavy rain will develop across New England and move north into Ontario and Quebec. The rain may begin as a period of freezing rain in the St. Lawrence Valley and Montreal as northeast winds keep the temperatures at or just above 0C. On Tuesday strong northeast winds and heavy precipitation are forecast. This system will bring 25mm (1 inch) or so of precipitation falling either as rain or a mix here in Montreal. There is the possibility that some warnings may be required, especially for the regions north or Montreal and the Ottawa Valley.
This same system dumped heavy wet snow across the southern plains over the weekend and is producing heavy rains across Pennsylvania and Ohio. Over 50mm (2 inches) of rain is forecast for the water logged region of southern New England and metro New York where flood watches have been raised. More warnings may be required later today and I will post them as they are issued. Check back this afternoon for an update.

The weekend looks variable as several fronts affect southern Quebec. It will remain mild, but clouds will be on the increase along with showers by Sunday. A steady rain may develop into Monday before it turns cooler with a snowflake or two. No major storms are on the horizon, but it will turn much cooler into next week as temperatures settle back to normal values for late March.
Spring arrives at 1:32pm EDT on Saturday.

Flooding spread across metro New York and New Jersey into Connecticut and Massachusetts yesterday and continues this morning. Numerous rivers are at record flood stage including the Merrimack River along the New Hampshire border with Massachusetts. Heavy rain and rapid snow melt have combined to produce what many had feared after this winters heavy snow, a rapid melt. Thankfully the storm that caused over 5 inches of rain and wind damage is moving into the Atlantic Ocean this morning. Skies are clearing out in all regions, and it will be sunny and warm for several days to help dry things out.
The next chance for rain in Montreal will come later this week. While it remains mild, and today is the official day in Quebec that you can remove snow tires, my advice would be to wait. Indications are there will be a major shift in the weather pattern the last week of March that could produce some snow in southern Quebec and Ontario. Stay Tuned! For the short term enjoy the sunshine and 14C weather today and Wednesday.

The storm that swept the metro New York region this weekend was the worst since hurricane Gloria in 1985. Winds of over 70mph tore down thousands of trees, crushing cars, homes and in some cases people. The storm left almost a half a million customers without power. This morning over 300,000 are still in the dark in metro New York, including Long Island, southwest Connecticut and New Jersey. In addition to the wind, coastal flooding and heavy rain has left many regions under water. Nearly 5 inches of rain fell with rivers still rising. Some evacuations will be needed especially in Massachusetts.
Montreal remained on the western edge of the storm with 50km/h winds (30mph) and about 18mm of rain or about 3/4 inch. In Montreal the sun is shinning this morning and it will be a fair and mild work week. Most of our snow is now gone with the exception of some dirty piles in parking lots.

As of 8am EDT this morning, a strong storm continues to spin off the Delaware coast. Abundant moisture and strong winds are feeding inland across New York, eastern Ontario and southern Quebec. The temperature in Montreal has been falling since late afternoon Saturday, and we are now at 1C with a rain/snow mix and northeast winds at 50km/h. The rain and cold temperatures with gusty winds will continue all day in the St. Lawrence Valley. Further south snow is accumulating across the highest elevations of the Green Mountains, so a winter storm warning has been posted for 4 to 7 inches of wet snow in that region. Coastal areas continue to see flooding and pounding waves. Flooding is also occurring across southern New England and western New York. Travel today with great care as roads are wet and in some cases snow is falling.
Of note the death toll is at 5 from falling trees in the New York metro region. Power remains out to hundreds of thousands across the tri-state region. Highways are closed from flooding and trees are down everywhere, too many to count.

The weekend will be decent in southern Quebec and eastern Ontario as we remain on the northern edge of yet another east coast storm, the same scenario that has played out all season. Saturday will be partly cloudy and mild, while Sunday will be much cooler with showers. This time it is a warmer storm system with heavy rain (not snow) and thunderstorms expected from the Ohio Valley into the middle Atlantic and northeast US. Winds and clouds will begin to increase in the St. Lawrence Valley late Saturday and into Sunday. With the storm passing to our south and east, winds in the valley will be out of the northeast, this should result in a very cool, raw day for the big St. Patrick's Day Parade in Montreal. While I think the heavy rain will stay to our south, any precipitation at plus 2C with a northeast wind will make it feel uncomfortable outside. It will warm again next week under clearing skies.
It has been a very dry start to March, just like February. To date in Montreal we have had 0.0mm of precipitation. You have to go back to February 27th for the last precipitation. Normally we should have 73.6mm for the month of March. February recovered during the last 10 days or so ending the month with 49mm including 47.8cm of snow. Normally we should have 61.5mm and 43cm of snow for February. So ironically we had more snow than normal last month, go figure, it sure did not show.

A true sign of the seasons yesterday as severe thunderstorm and tornado activity was reported across the southern plains of the US. Low pressure, which will become our weekend weather maker, moved from California across the southern plains producing the heavy storms and spawning a tornado near Hammon, Oklahoma. No injuries were reported, but damage was significant and 5 homes were destroyed. Tornado activity typically increases across this region from March into April and May before it shifts northward. On average Oklahoma records 4 March tornadoes, last year there was only one.
Meanwhile Montreal was sunny and a warm 10C yesterday as most of our snow continued to dissolve away. The forecast is for sunny and mild weather into Friday morning before the southern plains storm moves into the region with rain for the weekend.

Classic images of the Blizzard of 1971 in Montreal. My most vivid weather memories were of the small sidewalk plows like the one in the photo above and the scores of snowmobiles.
As we prepare to enjoy our first round of spring weather, my thoughts are on March 4, 1971, a day that I remember so well. I was only 5 years old when the largest blizzard in Montreal history slammed the city. I spent the day literally in the windowsill of our duplex on LaSalle Boulevard in Verdun watching the events unfold. We were right on the St. Lawrence River and the wind howled down that street. Little did I know that day would spark a lifelong passion in weather. It remains to this day the largest snowstorm to strike this city and parts of the province. The 24 hour snow totals were impressive with 47cm in Montreal and over 60cm in other parts of Quebec and Ontario. Drifts were over 6 feet high. That was just a small part of the story. This storm was an Atlantic nor'easter with the ferocity of a hurricane. The barometric pressure during the height of the storm dropped to 972mb or that of a Category 2 hurricane and winds gusted to over 120km/h in many parts of the St. Lawrence Valley including 110km/h at then Dorval Airport. I spent the day in the window watching snowmobiles go back and forth in the zero visibility for hours rescuing motorists and delivering people to area hospitals. Roads were closed including the 401 and 20 and power was out to thousands of Hydro customers.
I found some photos from a news report by Radio Canada and posted them on this entry.

Low pressure will move from Cape Hatteras, North Carolina to well east of Long Island, NY tonight. Snow has spread from the deep south through the middle Atlantic and into coastal New England today with up to 10cm of wet snow expected. Winds will be strong out of the northeast up to 80km/h. This weather will move into Maine and coastal New Brunswick and Nova Scotia tonight. Meanwhile strong high pressure will build into the St. Lawrence Valley with spring weather for Montreal. The only fly in the forecast will be gusty northeast winds from that Atlantic Ocean storm. They will blow out of the northeast in the order of 20 to 40km/h today making it feel cool and capping the temperature at 2 or 3C. Abundant sunshine will last into the weekend with warm temperatures, well above freezing during the day and just below at night, reaching 8C by Saturday. Yesterday it was colder in parts of Georgia and Alabama than it was in Montreal. Snow fell in Atlanta, closing roads and schools as the bizzaro winter of 2009/10 rolls along.

Enjoy the mild weather but remember, that March and April hold the distinction of having the biggest snowstorms in Montreal and southern Quebec including the record breaking March 4, 1971 storm and the March 13, 1993 super storm as well as on April 4, 1975. You get the idea I could go on there are so many more examples. I guess what I am saying is don't put away the shovel just yet.

Well it appears lamb-like across our region today. Low pressure once again along the east coast will provide steady snow and rain from New York City and Boston into Maine and the Maratimes. It will spare our area with the exception of a few showers or flurries and some gusty northwest winds. A few centimetres may accumulate near the US border and into Vermont. Skies will clear out very slowly on Tuesday and high pressure will take over and dominate the weather for the balance of the week with sunny skies and very mild temperatures. Overnight lows will be in the -5 to -8C range with daytime highs in the warm March sun soaring to between 4 and 6C on the plus side. Ice and snow will begin to melt quickly so keep that in mind when venturing near area waterways. Also make sure that drains and catch basins are free of snow and ice so that the winter can flow freely away!
