Snow to start Spring

A potent low pressure area is moving into the Great Lakes this morning and will pass just south of Montreal today. Snow is overspreading the region from eastern Ontario this morning and will become quite steady over the daylight hours today. Accumulations of 10-15cm are forecast for all regions with perhaps 5-10cm for the Ottawa Valley and up to 20cm in the Townships. Heavy Snow Warnings are in effect for southern Quebec with Winter Weather Advisories for northern Vermont and New York. Winds will be gusty out of the east and southeast up to 50km/h. Visibilities will begin to lower later this morning on area highways as the snow becomes steady. The snow could mix with rain at times and will taper off this evening.

Temperatures will remain right where they are this morning around 0C or plus 1C. Tonight will be cloudy with lows around -2C. Skies should slowly clear on Monday with highs remaining below normal at 2C. The entire week will be chilly with another chance for snow on Wednesday night.
