MESOSCALE DISCUSSION 0118
NWS STORM PREDICTION CENTER NORMAN OK
1208 PM CST WED FEB 19 2025
AREAS AFFECTED...PORTIONS OF NORTHERN/NORTHEAST NORTH CAROLINA INTO
SOUTHEAST VIRGINIA
CONCERNING...HEAVY SNOW
VALID 191808Z - 192315Z
SUMMARY...SNOWFALL RATES AROUND 1 IN. PER HOUR ARE POSSIBLE WITHIN A
SNOW BAND IN PARTS OF NORTHEAST NORTH CAROLINA AND SOUTHEAST
VIRGINIA. IMMEDIATE COASTAL AREAS COULD SEE SLIGHTLY HIGHER RATES.
DISCUSSION...AS MID-LEVEL ASCENT CONTINUES TO INCREASE ACROSS THE
MID-ATLANTIC THIS AFTERNOON, A COASTAL TROUGH IS EXPECTED TO DEEPEN
OFFSHORE. BY THE EVENING, A DEEPER SURFACE LOW SHOULD BE PRESENT OFF
THE COAST FROM THE CAROLINAS. THIS PROCESS SHOULD PROMOTE
LOW/MID-LEVEL FRONTOGENESIS ACROSS PARTS OF THE REGION. THIS ALREADY
APPEARS TO BE OCCURRING IN NORTHERN/NORTHEAST NORTH CAROLINA INTO
SOUTHEAST VIRGINIA. WAKEFIELD, VA ASOS HAS REPORTED HEAVY SNOW
WITHIN THE LAST 30-45 MINUTES. THIS BAND SHOULD CONTINUE TO
TRANSLATE NORTHEASTWARD THROUGH THE AFTERNOON INTO THE EVENING.
MODERATE TO HEAVY SNOWFALL IS PROBABLE WITHIN THIS BAND WITH OVERALL
RATES NEAR 1 IN. PER HOUR ANTICIPATED. SOME AREAS NEAR THE IMMEDIATE
COAST MAY SEE SLIGHTLY HIGHER RATES OR AT LEAST LONGER DURATION SNOW
AS THE FRONTOGENETIC LIFT SHOULD BE MAXIMIZED IN THESE AREAS.
SNOWFALL INTENSITY WILL EVENTUALLY DECREASE BY LATE EVENING INTO
THURSDAY MORNING. WITH SOUTHERN EXTENT, TOWARDS CENTRAL NORTH
CAROLINA, MORE OF A MIX OF WINTRY PRECIPITATION IS POSSIBLE ALONG
THE EDGE OF THE SNOW BAND AS THERE WILL BE GREATER INFLUENCE FROM
THE LOW/MID-LEVEL WARM NOSE.
