Blustery cold weekend
Strong low pressure over Atlantic Canada combined with arctic high pressure over Ontario will produce a tightening pressure gradient over Ontario and Quebec. The result will be increasing northeast winds into Sunday here in Montreal. Temperatures will fall to -19C tonight, combined with strong winds increasing to 30 to 50km/h producing dangerous wind chill values of at least -30C (-20 to -25F). A windchill advisory may be needed for a portion of the area for Sunday. Conditions will be mainly dry for the most part with just the occasional flurrie here in Quebec. The heaviest snow with the Atlantic storm will fall over New Brunswick. Meanwhile Windsor, Ontario has about 12cm of snow overnight, and some lake effect snow will continue today of Lake Huron and Georgian Bay. Temperatures will moderate on Monday. No big storms on the horizon for Montreal at this time.
