|Strong winds, rain and snow have made for a miserable holiday weekend in Manitoba. (CTV NEWS Manitoba)|
A strong low pressure area has been splitting the country in half as it moves from Colorado towards James Bay. To the west strong winds and heavy rain and wet snow have been reported from eastern Saskatchewan into northwest Ontario. Winnipeg is reporting snow this morning and a temperature of -1C (30F). Widespread frost was reported in Saskatchewan. Winds have been very strong across Manitoba, in excess of 80km/h with numerous reports of trees and power lines down. The same storm has a cold front trailing from it that will eventually cut through Montreal and the St. Lawrence Valley over the next 36 hours. That front produced lots of severe weather from Texas to the Dakotas on Saturday and again Sunday. Numerous tornadoes and large hail were reported with widespread damage. More strong thunderstorms are forecast from the Great Lakes to the Midwest today.

Montreal will remain between the Colorado low and a cool marine air mass just to our east on this Victoria Day Monday. We can expect a sunny and warm day with temperatures as warm as 30C (86F) in the southwest St. Lawrence Valley. Highs will be much cooler as you head east and southeast. Tonight the first of two cold fronts will produce showers and thunderstorms with a mild, humid low around 18C (65F). On Tuesday more showers and thunderstorms are forecast as a second cold front moves across Ontario and Quebec. The high Tuesday will be 24C (76F). The balance of the week will see clearing skies but much cooler with daytime highs below normal, only near 17C (63F). Temperatures will begin to warm once again by next weekend.
