AS THE UPPER-LEVEL TROUGH OVER THE EASTERN PART OF THE COUNTRY
DEEPENS OVER THE WEEKEND...THE LOW PRESSURE CENTER OFF THE
CAROLINAS IS EXPECTED TO DEEPEN OFF THE MID-ATLANTIC COAST. IN
ADDITION...A SURFACE TROUGH OF LOW PRESSURE IS EXPECTED TO FORM
ACROSS THE MID-ATLANTIC REGION AS WELL. PRECIPITATION IS EXPECTED
TO ORGANIZE ALONG THIS TROUGH OF LOW PRESSURE AND PICK UP IN
INTENSITY ACROSS THE NORTHERN MID-ATLANTIC AND NORTHERN
APPALACHIANS EARLY ON SATURDAY. AREAS IN THE NORTHERN APPALACHIANS
COULD SEE ADDITIONAL ACCUMULATIONS OF 4 TO 6 INCHES THROUGH SUNDAY

PENINSULA. EARLIER SNOWFALL HAS CAUSED WIDESPREAD POWER OUTAGES
ACROSS THE STATE OF PENNSYLVANIA. ACCOMPANYING THE SECOND ROUND OF
MODERATE TO HEAVY SNOWFALL WILL BE A POTENTIAL FOR COASTAL
FLOODING FROM THE MID-ATLANTIC COASTS NORTHWARD INTO SOUTHERN NEW
ENGLAND DUE TO GUSTY NORTHEASTERLY WINDS.
