The strong upper-level low will move through the Ohio Valley
today, causing the area of snow and freezing rain there to persist
and move northeastward. Freezing rain totals are expected to be
highest in the Ice Storm Warning area, and a few additional inches
of snow are possible in parts of the Ohio Valley as well before
ending on Thursday night. Additionally, the surface low pressure
system will strengthen over the Southeast coast and move as a
nor'easter along the Eastern Seaboard today and Friday. On the
back side of this surface low to the north and west, another area
of wintry weather is expected today. Freezing rain will be the
main threat across the Southern and Central Appalachians as warm
and moist air overruns the cold air in place at the ground. Ice
accumulations could be over a quarter of an inch there. Later
today and tonight the upper-level and surface lows will work more
in conjunction with each other to create heavy snowfall in the
northern Mid-Atlantic and into the interior Northeast.  Snow of 6
to 10 inches is forecast in portions of interior Pennsylvania and
the Northeast, with locally higher amounts.  The heaviest of the
wintry precipitation will remain west of the major cities of D.C.
to New York City, but a wintry mix is possible at the onset of
this event on Thursday and could cause travel issues before
transitioning to rain.

The next storm summary will be issued by the Weather Prediction
Center at 400 PM EST. Please refer to your local National Weather
Service office for additional information on this event.
