AS THE UPPER-LEVEL TROUGH OVER THE EASTERN HALF OF THE COUNTRY
DEEPENS OVER THE WEEKEND...THE LOW PRESSURE CENTER OFF CAPE
HATTERAS IS EXPECTED TO DEEEPEN WHILE DRIFTING TOWARD THE
NORTHWEST. IN ADDITION...A SURFACE TROUGH OF LOW PRESSURE IN PLACE
ACROSS THE MID-ATLANTIC REGION SHOULD HELP TO ENHANCE
PRECIPITATION ACROSS THE NORTHERN MID ATLANTIC AND NORTHERN
APPALACHIANS LATER TODAY. AREAS IN THE NORTHERN APPALACHIANS COULD
SEE ADDITIONAL SNOWFALL ACCUMULATIONS OF 2 TO 4 INCHES THROUGH
SUNDAY MORNING AS ATLATNIC MOISTURE WRAPS AROUND THE SURFACE LOW.
EARLIER SNOWFALL HAS CAUSED WIDESPREAD POWER OUTAGES ACROSS THE
STATE OF PENNSYLVANIA. ACCOMPANYING THE SNOWFALL WILL BE THE
POTENTIAL FOR COASTAL FLOODING FROM THE MID-ATLANTIC COASTS
NORTHWARD INTO SOUTHERN NEW ENGLAND AS NORTHEASTERLY WINDS
INCREASE AS THE SURFACE LOW NEARS THE COAST LATER TONIGHT.

THE NEXT STORM SUMMARY WILL BE ISSUED BY THE HYDROMETEOROLOGICAL
PREDICTION CENTER AT 1100 AM EDT. PLEASE REFER TO YOUR LOCAL
NATIONAL WEATHER SERVICE OFFICE FOR ADDITIONAL INFORMATION ON THIS
EVENT.
