Winter slow to arrive in Montreal

A new winter storm will develop over the Midwest and affect the central Great Lakes this weekend. Montreal will remain on the warm side of the storm. (AccuWeather)
November continues to be a warm month for Montreal and our surrounding regions. Yesterday Trudeau Airport reached 14C (56F), well above normal once again. The first 19 days of the month have generated an average daily high of 11.1C (52F) for the city, the normal should be around 6C (43F). Looking ahead, temperatures will try to cool on a couple of occasions, but basically remain above normal well into December. We have a couple of opportunities for some flurries this weekend and again early next week, but no major snowstorms are on the horizon at this time. A strengthening El Nino will continue to keep the cold air at bay, while deflecting any storms away from southern Quebec.

In the short term, the rain of Thursday has passed off to our east and we are looking at clearing skies today. It will be cooler than yesterday with our high already reached early this morning and temperatures cooling all day. The low tonight under clear skies will be 0C (32F). On Saturday, clouds will slowly increase as a developing storm over the Midwest US moves towards the Great Lakes and into western Quebec. This system will bring a period of light rain or flurries to the region late Saturday into Sunday. No major accumulations are expected in Montreal. Temperatures will remain mild for November with highs around 6C (43F) and lows near the freezing point. The bulk of the snow with this storm will affect places like Chicago and Milwaukee and points north, as well as central Ontario and north western Quebec. As the low passes on Sunday, cooler air will try to move into southern Quebec to start next week. Snow squalls may develop around the Great Lakes.
