Coldest morning of the winter in Montreal

The next chance for snow and rain arrives in Ontario and Quebec late Friday and Saturday. This will not be a big storm, but may still affect road travel.
Temperatures this morning across Ontario and Quebec are the coldest they have been since last February. L'Ile Perrot dropped to -22C this morning while Trudeau Airport is at -21C. Ottawa and Cornwall recorded -24C, Mirabel -25C and Sherbrooke the coldest in the region at -28C. High pressure is in control of the weather for the balance of the week with much needed sunshine and moderating temperatures. The high today will be a chilly -12C but temperatures will remain steady tonight or slowly rise as southwest winds develop. The high on Wednesday will be a mild -2C.

Our next chance for significant weather will arrive by late Friday or Saturday as a developing storm moves into the Great Lakes. This will not be a big storm, but we can expect a period of snow and rain with perhaps some freezing rain in some areas. Precipitation amounts at this time will likely be in the 5 to 10cm range with perhaps a few millimetres of ice or rain. A second more significant storm is possible later in the weekend and to start next week, but medium range computer models are having a tough time with the forecast, and there are just two many scenarios to mention more than that at this time. Further into next week colder air will return to southern Quebec, with the chance of another storm by late next week.
