10pm Update: At 10pm radar continues to show a nearly stationary band of moderate snow over the island of Montreal. Over 20cm has fallen since mid-afternoon here on Ile Perrot with winds gusting over 55km/h. Temperatures remain cold and travel is not advised in southern Quebec and eastern Ontario tonight. Snow extends all along the 401 and 20 from Kingston to Quebec City and roads are icy and snow covered. Visibility in southern Quebec in most cases is less than 2km. Snow and blowing snow are also occurring in Vermont and New York. Winter Storm Warnings are in effect there with 4-8 inches expected near Lake Champlain and 8-16 inches in the Green Mountains and Adirondacks. Avoid travel tonight on area highways.

They say timing is everything. I just arrived home from work at 8:30pm. I left work at 5:30pm. Montreal traffic was nearly at a standstill as near blizzard conditions developed late this afternoon. Heavy snow and blowing snow have already snarled traffic and delayed commuter trains by up to 2 hours tonight. When I arrived home on L'Ile Perrot, trusty yardstick in hand, I measured 20cm in my driveway. Environment Canada was expecting 2-4cm but they have changed that to 10-15cm. Radar is showing a nearly steady band of snow over the western tip of the island of Montreal. Low pressure is backing into Quebec at this hour from the Atlantic with copious moisture. If you read my blog at all in the last week you knew this was a possibility. Too bad Transport Quebec does not read my blog. Very little plowing and salting has been done.
As of 8pm the temperature at Dorval had dropped to -5C at the airport with a windchill of -14C. Winds were gusting to 52km/h with a pressure down to 988mb and it was snowing. The visibility was under 1km. I will update the weather again within the next hour or two.
