January 21, 2014 –

Along the leading edge of the invading polar blast, accumulating snow was spreading from the Midwest to the East Coast on Tuesday.

Snow was reaching the mid-Atlantic coast during Tuesday midday and afternoon, and will then turn northeastward toward southeastern New England Tuesday evening.

As the storm reaches the coast, it will strengthen, snow will become heavy and winds will increase along a large part of the I-95 corridor of the Northeast.

Much colder air continued to push southward over the mid-Atlantic Tuesday. In most cases, temperatures will hold steady or fall throughout the day.

Travel conditions will deteriorate rapidly due to slippery roads and diminishing visibility. Flight delays were beginning to unfold in the region ahead of the storm. As the air turns colder, the snow will become dry and powdery. Increasing winds will cause extensive blowing and drifting snow.

The worst conditions in the coastal mid-Atlantic will be Tuesday afternoon into the evening. For southeastern New England, the storm will reach its peak later Tuesday night.

For part of the mid-Atlantic such as the District of Columbia and a large part of Virginia, Delaware, Maryland, New Jersey and southeastern New York state including Long Island, this could unfold to be the biggest snowfall of the season so far.

This storm could rival the storm from early December in parts of southeastern Pennsylvania and Delaware.

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 6-12 inches are forecast over a heavily populated part of the mid-Atlantic to southeastern New England. Cities such as Baltimore, Philadelphia, New York City and Boston will be faced with at least 6 inches of snow from the storm as well as blowing and drifting snow after its conclusion.
