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!
