NWS STORM PREDICTION CENTER NORMAN OK
1227 PM CDT THU MAY 22 2025
AREAS AFFECTED...SOUTHERN DELMARVA PENINSULA INTO THE SOUTHERN
CHESAPEAKE BAY VICINITY
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 221727Z - 221930Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...ISOLATED DAMAGING WIND GUSTS ARE POSSIBLE THIS AFTERNOON
FROM THE SOUTHERN DELMARVA PENINSULA INTO THE SOUTHERN CHESAPEAKE
BAY VICINITY.
DISCUSSION...LIMITED DESTABILIZATION IS ONGOING ACROSS FAR SOUTHEAST
VA INTO THE SOUTHERN DELMARVA PENINSULA AS FILTERED DAYTIME HEATING
OCCURS AMID MODEST LOW-LEVEL MOISTURE AND COLD TEMPERATURES ALOFT.
THIS DESTABILIZATION IS OCCURRING ALONG THE NORTHERN PERIPHERY OF
THE STRONGER MID-LEVEL FLOW, WHICH IS CONTRIBUTING TO 40-50 KT OF
0-6 KM BULK SHEAR ACROSS THE REGION. LARGE-SCALE FORCING FOR ASCENT
WILL LIKELY PERSIST ACROSS THIS AREA AS THE UPPER TROUGHING MOVES
THROUGH, AND THE GENERAL EXPECTATION IS FOR OVERALL STORM COVERAGE
TO INCREASE. INSTABILITY IS EXPECTED TO REMAIN MODEST, LIKELY
LIMITING THE OVERALL UPDRAFT STRENGTH/DEPTH. HOWEVER, MID-LEVEL
TEMPERATURES ARE EXPECTED TO CONTINUE COOLING, SO THERE WILL LIKELY
BE ENOUGH BUOYANCY FOR A FEW DEEPER CORES. ADDITIONALLY, THE
ENHANCED MID-LEVEL FLOW ACROSS THE REGION COULD AID IN THE
DEVELOPMENT OF A FEW STRONGER DOWNDRAFTS WITHIN THE STRONGEST
STORMS. EVEN SO, THE OVERALL COVERAGE OF DAMAGING WIND GUSTS IS
EXPECTED TO REMAIN LOW THROUGHOUT THE AFTERNOON.
