Windy fall storm for southern Ontario & Quebec

 A strong low pressure area moving from Utah towards Lake Huron is creating all kinds of bad weather for millions today. The storm, centered over northern Michigan this morning, brought heavy snow to portions of the Rockies. East of the trajectory, strong thunderstorms and tornadoes occurred Wednesday. Rain is occurring in advance of the storm, while on the backside, heavy wet snow is falling across the upper Midwest and far northwest Ontario. The storm is also producing very strong winds along its path. High wind warnings are in effect for portions of southern Ontario along Lakes Erie and Ontario. Wind gusts in excess of 90km/h are forecast. Strong winds will spread into southern Quebec late today and Friday, with gusts up to 70km/h expected in Montreal. The gusty winds have also prompted storm surge warnings for portions of the Maritimes and the Gaspe coast.

Rain is forecast to develop shortly in Montreal, with showers expected through Friday. Temperatures will be mild on the east side of the storm, but as the low slips across Quebec on Friday, cooler air will pour in behind it. The rain may change briefly to a period of wet snow late Friday night in parts of southern Quebec. Just a trace is possible in the valley locations, but 5-10cm may fall across the highest elevations of the Townships, the Green and Adirondack mountains. Temperatures will be mild today, up to 12C (54F). On Friday it will turn cooler with the high early in the day and temperatures falling to near freezing late Friday, in Montreal. Saturday will be cloudy, breezy and cool with an overnight low of -3C (27F) and a high of 5C (41F). The weather will turn warmer again next week.
