Much colder air for the weekend

The light snow that is falling this morning will end quickly from west to east as the morning progresses. Around 2cm has fallen in the region. Kemptville is above freezing at the moment so the snow is actually melting off vehicles. The cold air will begin mixing down to the surface soon and temperatures should fall below freezing again. It will be windy this afternoon with gusts over 50km/h, so there could be some drifting snow in open areas. Tomorrow another arctic front will move through the area with gusty winds and another 5cm of snow. It could be nasty on the roads with strong winds at times and dropping temperatures. This will be especially true closer to the Great Lakes and St. Lawrence River Valley. The colder air moves in behind that front with temperatures dropping to -20C Saturday and Sunday night before a slight warm up early next week back to normal temperatures. for a day or two.
