Happy Halloween - dry for metro Montreal

Schultz image

It looks like the weather will be decent for trick or treating in Montreal. Low pressure developing over the Great Lakes will produce light rain and snow for portions of Ontario today including Toronto. While it will be a cloudy, cool day in the St. Lawrence Valley, any shower activity should stay away from metro Montreal until after midnight. Temperatures are chilly today, at 0C (32F) right now here on L'Ile Perrot. Look for a high near 7C (45F) with temperatures around 5C (41F) during the trick or treating.

The Great Lakes low will move south of Montreal and off the Atlantic seaboard by Saturday where it will combine with another disturbance and develop a potent Nor'Easter. This storm system will guarantee a windy, chilly and gray weekend for Montreal, but no snow expected at this time as it remains well offshore. The snow will be confined to the Gaspe region of Quebec as well as interior Maine and New Brunswick. A stray snowflake or two may develop over the Townships late Saturday.

Have a safe and Happy Halloween!
