Surprise...SNOW

I was expecting partly cloudy skies with moderating temperatures today, but surprise it is snowing out across southern Quebec. A front is stalled along the US border separating the mild air and partly cloudy skies to the south and the much colder arctic air mass to the north. Portions of the St. Lawrence Valley remain chilly with Montreal at -11C, but south of the front, Burlington, Vermont is at -4C with fog and mist. The warm air overrunning the colder air at the surface here in the valley is producing widespread light snow. Radar is showing the snow stretching across eastern Ontario and into western Quebec and the Montreal area. The snow will continue most of the day with up to 5cm of fluffy accumulation expected. Winds are light out of the northeast keeping the air cold. It may warm to -8C or so today but not much better than that.
