Another round of snow for Montreal and southern Quebec

Winter Weather Advisories are in effect for the Ottawa and St. Lawrence Valley, with snowfall warnings for the Laurentians and Gatineau regions.

A potent Alberta Clipper will move across southern Quebec late Saturday into Sunday morning, with a quick burst of moderate snow. The snow is already spreading across eastern Ontario and should arrive in southern Quebec over the next few hours. Expect a quick 10cm of snow for most locations, including Montreal, with as much as 15cm across the Laurentians and Ottawa Valley.

Roads will become snow covered and slippery Saturday night, and visibility will lower to under a kilometre or two in moderate snow at times. Expect conditions to improve Sunday morning as temperatures rise close to the freezing point and precipitation tapers off to drizzle. 

The weather will remain very active this week, as several storm systems and frontal boundaries traverse the region. We are looking at a messy mix of precipitation across the area, with more snow, freezing rain and rain likely. The time frame to watch for mixed precipitation will be late Monday and again Wednesday evening. The entire mess will freeze up Thursday behind a cold front as temperatures drop.

Winter driving is certainly back so plan for a slippery week ahead at times, starting Saturday evening.
