Arctic Chill

Deep cold arctic air is moving into eastern Canada along a cold front today with plenty of instability and breezy conditions. As a result, an area of snow and flurries has developed and has become quite steady in Montreal and along the St. Lawrence Valley. The snow is being enhanced near any body of water as the cold air continues to flood into the region. The snow will continue intermittently for most of the day and a few centimeters may accumulate locally. Roads will become snow covered and slippery in the cold temperatures. We have likely reached our high for the day and temperatures will remain steady or drop slowly. Tonight skies will clear, and with the fresh snow cover temperatures will drop into the minus 20’s in eastern Ontario and southern Qu├ębec. It will remain cold right into this weekend.
