Snowy week for Montreal

A burst of moderate snow on L'Ile Perrot last night left about 8cm on the ground. (ValleyWX)
While it is not a storm as such, there will be enough snow to shovel and plow over the next few days across southern Ontario and Quebec. A trough of low pressure swung across southern Quebec last night with a surprising burst of moderate snow between 7:30pm and around 11pm. Some locations reported as much as 8cm with 6cm officially at Trudeau Airport. That amounts to 2 or 3 inches in just a few hours. This morning the gusty northwest winds are blowing that snow around and they will continue most of the day up to 60km/h.

A large upper level low will slowly drift across eastern Ontario and southern Quebec well into Friday with periods of snow. The snow will be light most of the time with amounts in the 5-10cm range by late Thursday with higher totals across the snow belts of the Great Lakes and in the mountains north and southeast of Montreal. Friday looks fair at this time before another low and frontal system approaches the St. Lawrence Valley for Saturday. Temperatures will be slightly cooler today around -3C but warm to the freezing point for the balance of the week. Overnight lows will generally be mild around -5C.
