I'm getting more impressed with this potent upper-level storm system that will quickly track into Ontario by Tuesday evening and then into the Northeast U.S. and Maritimes Tuesday and Tuesday night.
The Canadian model has done a pretty good job of catching the strength of this system from a few days out.
The map below that I drew at home shows the range of snowfall that I expect with the arrival times of snow. This will be a quick-moving storm, almost like one big warm front as the air will turn mild behind this system.
The storm will last an average of six hours in most places, perhaps a little more, but with the bulk of the snow coming in a three- to four-hour period when the snowfall rates could reach 2-5 cm (1-2 inches) per hour with strong upward motion in the atmosphere.

Some snow today across southwestern Ontario as the west remains under strong high pressure ridge.
Significant snow is likely for parts of New Brunswick this weekend.
Cold air expected to spill into eastern North America in about 10 to 14 days.
Arctic air likely to retreat well to the north as we go into early December.
Active weather pattern through next week.
