Most of the Northeast dodged a bullet with this storm. Why? Simply, there was no big arctic dome in place before the storm hit. Storms that produce major snowfalls always attack large, cold high pressure systems. This gives the air extra lift which is a prerequisite for heavy snow. If there is no high in the way, upward motion is less intense, and a monster snowstorm can't happen.

Tuesday night, snow will spread from southern Vermont and New Hampshire into southern Maine. Along a line from Concord, N.H., to Bangor, Maine, up to 6 inches of snow will accumulate. Over 6 inches of snow can be expected in New Brunswick later Tuesday night and Wednesday.

Through southeastern New York, western Connecticut and western Massachusetts, the snow will stop this evening.

The region from Ohio through southwestern Pennsylvania into West Virginia could pick up a couple of inches of snow overnight from heavy snow showers. The snow may accumulate 6 or 8 inches in the Laurel Mountains of southwestern Pennsylvania, in Garret County, Md., and in the mountains of West Virginia.
