Along the leading edge of the invading polar blast, accumulating snow will spread from the Midwest to the East Coast on Tuesday.
The snow will become heavier as it streaks across the mid-Atlantic on Tuesday, then makes a northeastward turn toward southern New England late in the day and evening……
………According to Winter Weather Expert Brian Wimer, “For Washington, D.C., this could be the biggest storm since Jan. 26, 2011, when about 5 inches of snow fell.”
Accumulations of 3 to 6 inches are forecast over a heavily populated part of the mid-Atlantic to southeastern New England.
