Cold weekend ahead - but warmer weather on the way

The first significant snowfall of the season on Thursday produced a record-breaking 7cm of wet snow across the Montreal region. The snow iced roads and bridges leading to several major accidents and significant traffic delays. Conditions have vastly improved Friday morning. (Valley Weather)

A bulk of the 7cm of snow that fell in Montreal Thursday is gone already early Friday morning. The temperature has risen well above the freezing point and sits at 4C (39F) currently. We can expect a mild, windy high of 7C (45F), with winds out of the southwest 30-50km/h.

A cold front arrives this evening, setting the stage for a chilly weekend. Along the front look for scattered showers and flurries, followed by clearing skies and cold temperatures. Morning lows on both Saturday and Sunday will be down to -3C (27F) in the Montreal region.

Another round of showers is possible early next week, but the main story will be warming temperatures. Winter is not yet ready to take over. As a matter of fact, November is looking like a typical El Nino month, with more warm and dry days expected than wintry ones. This will give motorists a few more weeks to prepare for winter, because quite clearly many were not on Thursday.

The snow that fell quickly iced roads, especially elevated surfaces. The result was the typical nonsense that greets drivers every year as the first flakes fly. Numerous accident were reported, along with major delays during the morning commute. Conditions improved in the afternoon as temperatures warmed to the freezing point and the precipitation came to an end. Get those snow tires on!

The 7cm of snow that fell on Thursday at Trudeau Airport set a new daily record for November 9, surpassing the previous benchmark of 1.8cm set in 1952.
