Quiet February rolls along

It looks like much more of the same in southern Quebec this week as high pressure will dominate the weather until mid-week. We start with a rather weak warm front lifting north of the St. Lawrence Valley this morning, accompanied by a few flurries, perhaps 1cm in elevated locations, if we are lucky. Temperatures were rather cold this weekend, but will rise to well above normal again this week as the arctic air shifts back to the north where it has been trapped most of the winter. Temperatures will be in the -2 to -4C range to start the week but warm to above freezing by Wednesday. Low pressure will head into the Ohio Valley by Thursday and take aim at southern Ontario and Quebec. At this time it looks like rain and maybe freezing rain to start perhaps ending in a period of snow. It is still early for that system, so we will wait and see as the week moves along.

Moncton on Sunday morning (

The big storm this weekend was a rapidly deepening Atlantic storm that split the Maratimes in two with rain along and east of the track and heavy snow to the west. Snow fell fast and furious in Moncton and Charlottetown on Saturday night with between 25 and 40cm of snow. In Charlottetown, 32cm fell in just 6 hours. The storm also produced strong winds that cut power to wide areas of Nova Scotia, New Brunswick and PEI. In Newfoundland it was mostly a heavy rain event with some flooding reported as over 70mm of rain fell. Winds gusted to hurricane force with 107km/h observed at St John's, 124km/h at Burgeo and 148km/h at Wreckhouse. That gust at Wreckhouse damaged the anemometer, so that was the peak gust with the storm, but it might have been higher. Meanwhile in Labrador full blizzard conditions prevailed with heavy snow, gale force winds and windchill values as cold as -48C. It is frigid in Atlantic Canada this morning under clear skies and deep snow pack temperatures are in the minus 20's.
