Thursday update...

The first snowflakes of the season fell in Montreal this afternoon. Accumulations were light as witnessed on my Saturn above.

5PM: Radar is showing the back edge of the cold front moving south through the Montreal area. Wet snow is falling on the West Island (2C) and north of the city. Travel with extreme caution tonight as temperatures are expected to drop below freezing before the precipitation ends before midnight. Roads will be slick.

1PM: Latest update on the area weather. It is very chilly in Montreal at only 2C. The rain is ever so close to being wet snow, and you don't have to go far to the northeast to find snow. Snow is falling east of Quebec City and areas to the north. Travel is difficult along highway 20 east of Quebec City. Environment Canada has posted a snowfall warning for Montmagny - L'Islet and the Laurentian Wildlife reserve for 10-15cm of wet snow this afternoon. Highway 20 runs through that region for anyone heading to Atlantic Canada today. The cold front is now on radar approaching Ottawa and it will move into Montreal this afternoon. A period of heavy rain and even some thunder along with gusty winds is possible along the front.

Just a quick update on the current weather in the region. Low pressure over eastern Ontario has a warm front to our south and a cold front to our northwest. The showers have ended for the time being in Montreal, but will reform along the cold front this afternoon. It will remain cool in the St. Lawrence Valley with northeast winds and a temperature of only 4C in Montreal but Kemptville may make it into the warm sector for a brief period. Toronto is currently 13C south of the front. Northeast of Montreal in a swath from the Quebec/Ontario border across to east of Quebec City and into northern New Brunswick, snow is falling. Amounts may be as much as 10-15cm locally. Keep this in mind if you are traveling to Quebec City today, where it is currently 0C and snowing. The warm air will remain to our south with this system. Friday will be sunny and cool behind this storm. The weekend looks rainy but mild Saturday with clearing skies Sunday.
