A major winter storm affected the northeastern United States,
including the northern mid Atlantic region, during Saturday February 11th and Sunday February 12th. An area of low pressure
developed along the Gulf Coast states on Friday February 10th.
and began moving to the northeast toward the North Carolina
coast during February 11th.
Snow overspread the region around 11 AM EST on Saturday
from south to north. The precipitation initially was relatively light with temperatures either at or above freezing.
The snow really increased in intensity across eastern Pennsylvania
around Midnight EST on Sunday the 12th and around 2 AM EST in the Philadelphia Metropolitan area. The snow gradually ended
from southwest to northeast around Noon EST on the 12th. The snow fell steadily and became heavy at times in many areas late
Saturday night and Sunday morning.
The last strong band of snow passed through during the
mid morning hours on Sunday. During this strengthening storm, a good portion of the region experienced intense snowfall rates
of 2 to 4 inches per hour.
These intense snowfall rates mainly occurred during Sunday
morning the 12th as the storm really intensified off the Delaware and southeast New Jersey Coasts. During the height of the
storm on Sunday morning the 12th, thunder and lightning occurred as the snow fell. The presence of this thundersnow just goes
to show how energetic this storm became. Also, winds gusted to about 40 mph. The gusty winds, coupled with the falling and
accumulated snow, produced near whiteout conditions along with drifting snow across a good portion of the area.
The storm moved away from the region on Sunday afternoon
the 12th, allowing the accumulating snow to come to an end.
