Frigid Friday & potential weekend storm for Montreal

A lonely park bench along Lakeshore Drive in Dorval this morning., no doubt waiting for spring like the rest of us. Strong winds, blowing snow and dropping temperatures for the rest of the day today in Montreal. (ValleyWX Photo)
We are awaiting the arrival of an arctic front slipping across the Ottawa Valley early this morning. Along the front is a brief shot of heavy snow and blowing snow dropping 2-4cm with gusty winds. Behind it more cold air pouring into the region. Montreal is currently -3C (27F), our high for the day. Temperatures will drop towards -12C (10F) by days end and to -22C (-8F) overnight. Strong northwest winds up to 50km/h will produce dangerous wind chill values across Ontario, Quebec and northern New England today, especially on the ski hills. As quickly as temperatures fall today, they will begin to rebound Saturday and Sunday as warmer air circulates around low pressure developing south of the Great Lakes. Highs Saturday under partly cloudy skies will be -10C (14F) with 0C (32F) Sunday.

A second more potent storm still looks likely late Sunday into Monday for a portion of our area. The models continue to disagree on the track and intensity of the storm, leading to low forecast confidence at this time. It certainly looks like we will see accumulating snow late Sunday into the Monday morning commute in Montreal. At this point amounts and the exact location remain difficult at best. I am watching this closely and will post updates later today. In the meantime stay warm today and drive safe.
