Classic Nor'Easter - Montreal on the northern edge

Radar this morning clearly showing both storms as they converge on New England. Heavy snow is falling from Toronto across Ontario to the Quebec border. Meanwhile more heavy precipitation is moving north from the middle Atlantic.
Quickly here is the latest on the winter storm affecting Ontario and southern Quebec. We have winter storm warnings posted from Montreal southwest to Windsor. They have been extended northward to include the Ottawa Valley. Basically we are looking at a very cold day with gusty northeast winds up to 60km/h and lots of snow and blowing snow. Accumulations will be in the order of 10cm in the northern regions to 25 or 30cm towards the US border and Lake Ontario. In metro Montreal 10cm over the island and Laval with 15cm from L'Ile Perrot south and up to 25cm near the New York border.

By tonight this low will become absorbed by a much larger system that is taking shape this morning along the North Carolina coast. That storm will move towards Cape Cod while deepening rapidly. This will be a major blizzard for New England and Atlantic Canada with 100km/h (60mph) winds and 1 to 2 feet of snow. Already this morning delays and cancellations are pouring in. Coastal flooding will be a big issue from Massachusetts along the coasts of New Hampshire, Maine and Nova Scotia. Large, damaging waves will surge in along the coast.

With the snow affecting such a large area in the east, air travel will be severely disrupted - call ahead. Also, if you are thinking about driving to Ottawa, Toronto or Boston today, I would strongly advise that you don't.
