Blowing Snow

It was really cold last night in Montreal. I was surprised just how chilly it was while cleaning my driveway last evening. When I left the house yesterday morning, it was -4C. Last night we dipped to -17C with a windchill of -27C jut before midnight. The cold air poured in behind a strong cold front that swept the valley around 8am. The temperature has since risen to -9C in response to another approaching cold front, and will drop again later today. That front will have limited moisture, but very gusty southwest winds in the St. Lawrence Valley with 60km/h not out of the question. The winds are producing blowing snow, especially in open areas. Yesterday another 5cm of snow fell with another 5cm possible over the next 24 hours. There may be a burst or two of steady snow. If you are travelling the 401 to Toronto you may encounter some heavier snow before Kingston to near Trenton off Lake Ontario.

The balance of the week will be unsettled with seasonable temperatures around -5C during the day and -12C at night. Just a few flurries are possible. The next threat for snow will be late Sunday from a weak Clipper system. Next week will be much milder.

This morning another windy snowstorm is moving across the southern plains. Overnight about 4 inches fell in Oklahoma City with upwards of a foot along the Kansas border.
