Snow followed by very mild weekend for Montreal

A surge of warm air will arrive across southern Ontario and Quebec just in time for the weekend. Clouds are already thickening up this Friday afternoon in advance of a rather potent warm front. The front will have an area of moderate snow along it affecting mostly the regions from Ottawa and Montreal north. A heavy snowfall warning is in effect for 15-20cm across the Laurentians and upper Gatineau. Montreal is expecting 5-10cm of wet snow, starting this evening and changing to light rain by Saturday morning. Gusty south winds will help push the temperature up to 0C (32F) overnight and then to 5C (41F) on Saturday. The temperature will remain above freezing through Sunday afternoon along with scattered showers. It will be very windy late today and overnight with gusts up to 60km/h in the St. Lawrence Valley. East of Montreal in the Richelieu Valley, winds will approach 90km/h, as a result a wind warning has been issued for that region.
Another potential snowstorm is forecast to develop in the southern US on Tuesday and possibly impact Quebec and eastern Ontario next week. (AccuWeather)

Winter Storm?
Colder air will return late Sunday with overnight lows dropping to -14C (7F) by Monday morning. We are looking at the potential for another major winter storm for next Wednesday and Thursday. Like last week, the specifics are all over the place as low pressure is expected to develop Tuesday and move up the east coast. I will try to nail down a forecast over the weekend. Last week turned out just about spot on, so lets see what this storm does. Have a great weekend!
