Snowfall Warning in effect for Montreal, Ottawa and Cornwall

The weather remains rather quiet and dismal across southern Quebec on Wednesday, with just a couple of weak systems impacting the region. The result has been plenty of cloud cover, some light precipitation at times in the form of drizzle or flurries, and little range in temperature. Temperat…

This is a follow-up to the story I wrote back in January 2017. If I seem a little nostalgic at times for winter during that decade, I am. While mild winters are certainly welcome by most, I prefer more traditional winter weather, at least in December and January. The extreme changes in tempe…

Strong high pressure over our region is being blocked from any eastward movement by an upper level low northeast of Atlantic Canada. This is forcing all the weather systems to slow to a crawl, and pushing any storms well south of our region across the southern US. So what you see is what you…

Precipitation has come to an end in Montreal, with temperatures hovering around the freezing point early Thursday morning. It is just cold enough outside for a thin layer of ice on everything, as I found out the hard way leaving the house this morning. The clipper system is now well northeas…

In a scenario all too common this year, another snowstorm is missing southern Quebec, but not by much. A massive Nor'Easter is currently strengthening off the Carolina coast, poised to dump 30-60cm (1-2 feet) of wind-driven snow from Virginia to Nova Scotia. Snow has already started falling …

Winter is desperately trying to establish a foothold in southern Quebec. But with no real cold air in place, it has been difficult at best. The little snow that has fallen to date, including the 4 to 5cm of snow that fell on Wednesday in Montreal, melts away very quickly. Even milder air is …

A poorly timed burst of snow Wednesday morning has turned the commute in Montreal into carnage on the highways. Traffic is crawling in many areas due to the combination of light snow and black ice. Traffic was moving way too fast for the conditions earlier this morning. I witnessed a Hummer …

It is yet another dreary morning in Montreal, with a light cold rain falling. The day will shape up cloudy, with scattered showers and flurries and temperatures fairly steady near 2 or 3C. The big weather news is the potential for a snowstorm this weekend. But before you get too angry or exc…

Colder weather has returned to southern Quebec after our remarkable stretch of warm weather. Conditions were similar to late summer then mid-November. By the numbers it was very impressive. There were dozens upon dozens of new record highs established from central Ontario to Atlantic Canada.…

The wind in the wires made a tattle-tale sound - And a wave broke over the railing - And every man knew, as the captain did too, T'was the witch of November come stealin'.

What a spectacular weekend it was across southern Quebec and Ontario. The weather was more like early September than mid-November. Numerous record highs were established from Ontario to Atlantic Canada. Here in Montreal the high both Saturday and Sunday was just shy of the 20C (68F) mark alt…

Friday has turned into a spectacular late October day across southern Quebec and eastern Ontario. Temperatures have warmed into the low 20s (70s). The record high for Montreal for October 23 was 25C (77F) set in 1979. We will likely fall just short of that, but it will be pleasant nonetheles…

The first snowflakes of the season fell across portions of southeastern Quebec and adjacent northern New England late Friday into early Saturday morning. The snow was produced by deep Atlantic moisture being transported inland by a developing coastal storm. Meanwhile a cold front that gave M…

Fall is well underway across southern Quebec, but with a hint of summer still around and a sprinkling of winter. October, or as I like to call it the April of fall, is a month full of contrasts and the occasional surprise or two. We often see summer warmth, thunderstorms, frost and even snow…
