Major Snowstorm Unfolds in DC, Philly, NYCAccumulations of 6-12 inches are forecast over the heavily populated Mid-Atlantic
Along the leading edge of an advancing deep freeze, accumulating snow was spreading from the Midwest to the East Coast on Tuesday.
Snow reached the mid-Atlantic coast during Tuesday midday and will turn northeastward toward southeastern New England Tuesday afternoon and 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 continue to deteriorate rapidly due to slippery roads and diminishing visibility. Speed restrictions were already in place by the Pennsylvania Department of Transportation Tuesday morning.
Flight delays were mounting in the region ahead of the storm.
Thousands of arrivals and departures were canceled as of noon on Tuesday.
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 persist 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 is unfolding 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.
As the storm gains strength Tuesday night, blizzard conditions may unfold in portions of Long Island, southeastern New England and during Wednesday in portions of New Brunswick and Nova Scotia.
Already Tuesday afternoon, visibility had decreased to only one-quarter of a mile in Westhampton Beach.
The mountains of Virginia and West Virginia will likely receive close to a foot of snow from this quick-moving storm.
Much less snow will fall over northern Pennsylvania, upstate New York and the northwestern part of New England. In these areas, cold, dry air will win out.

Motorists planning to travel along I-64, I-66, I-68, I-70, I-81 and I-95 should use caution.
A little snow will even drop southward to Greenville, S.C., and Winston-Salem and Raleigh, N.C., through Tuesday evening.
In the wake of the snow, the door will open for cold air to settle across the entire East for midweek. Highs on Wednesday will be held 10 to 20 degrees below normal, even down to Miami.
Sunday morning was the coldest so far this winter across most of South Florida. Frost even made a rare appearance in Naples and the western suburbs of the Palm Beach metro area.
Wednesday night may not be quite as cold as this past Sunday morning, but frost could return to the coldest interior locations of the Florida Peninsula.
After the midweek cold snap, another dose of cold air will follow later in the week for the South.
