NWS STORM PREDICTION CENTER NORMAN OK
0252 PM CDT THU MAY 21 2026
AREAS AFFECTED...SOUTHERN APPALACHIANS INTO PARTS OF SOUTHERN
VA/NORTHERN NC
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 211952Z - 212145Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...LOCALIZED DAMAGING WINDS ARE POSSIBLE THROUGH THE
REMAINDER OF THE AFTERNOON.
DISCUSSION...SCATTERED THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON
FROM NORTH GA INTO SOUTHERN VA. CONVECTION IS GENERALLY DISORGANIZED
WITHIN A MODESTLY UNSTABLE AND WEAKLY SHEARED ENVIRONMENT, THOUGH
OCCASIONALLY ROBUST CELLS HAVE DEVELOPED IN THE VICINITY OF A COLD
FRONT ACROSS SOUTHERN VA. RELATIVELY STRONG HEATING AND STEEPENING
OF LOW-LEVEL LAPSE RATES HAS OCCURRED FROM THE SOUTHERN APPALACHIANS
TO AREAS OF SOUTHERN VA/NORTHERN NC ALONG/SOUTH OF THE COLD FRONT,
WHICH WILL RESULT IN SOME POTENTIAL FOR LOCALIZED DAMAGING OUTFLOW
WINDS IN ASSOCIATION WITH THE STRONGEST UPDRAFTS/DOWNDRAFTS.
INCREASING STORM COVERAGE MAY RESULT IN A SOUTHWARD-ACCELERATION OF
THE COLD FRONT ACROSS SOUTHERN VA/NORTHERN NC THROUGH LATE
AFTERNOON, WHICH COULD RESULT IN A BROADER AREA OF STRONG BUT
GENERALLY SUBSEVERE GUSTS AND LOCALIZED WIND-DAMAGE POTENTIAL.
