Record Highs

It was unseasonably warm across southern Quebec and Ontario on Monday with numerous record highs broken. They included 18.6C at Trudeau Airport in Montreal, and 18.2 at St. Hubert. St Anicet near the Ontario border was 19C but this fell just short of the record 19.8C set in 1994. It is cooler today with a high of 12C forecast, but that is still well above the normal high of 5C for November 15. Meanwhile severe weather spread from Arkansas to western New York yesterday in the warm air with reports of hail, high winds and even tornadoes. Damage was observed in may locations across Ohio and Indiana.

Out west arctic cold is plunging into Alberta and Saskatchewan and even west along the BC coast. Snow and windy conditions are accompanying the cold. It is -9C is Edmonton this morning with a fresh coating of snow on the ground, and it will be as cold as -20C by Friday morning. As the cold air moves east, it will moderate somewhat, but still be cold enough to produce lake effect snow over the Great Lakes by late Wednesday and Thursday. More on that tonight. The cold air will eventually be into Montral by the end of the weekend with lows below freezing and highs just above at plus 1 or 2C.
