AREAS AFFECTED...ERN NC...SERN VA
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 081540Z - 081645Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...ISOLATED DAMAGING WINDS MAY ACCOMPANY EXPANDING COMPLEX OF
TSTMS OVER ERN NC INTO SERN VA.
DISCUSSION...LATEST WV IMAGERY SUGGESTS SRN INFLUENCE OF SHORT-WAVE
TROUGH IS EJECTING NEWD ACROSS ERN NC/SERN VA. OVER THE LAST HOUR
OR SO NUMEROUS SHOWERS/TSTMS HAVE DEVELOPED AHEAD OF THE TROUGH
WITHIN A VERY MOIST AND MODESTLY SHEARED ENVIRONMENT. SFC-3KM LAPSE
RATES HAVE STEEPENED SIGNIFICANTLY WITH VALUES APPROACHING 8 C/KM
AND THIS SHOULD CONTRIBUTE TO ROBUST UPDRAFTS/DOWNDRAFTS ACROSS THIS
REGION. TIMING OF THE EJECTING TROUGH SUGGESTS CONVECTIVE THREAT IS
GREATEST OVER THE NEXT SEVERAL HOURS. DAMAGING WINDS SHOULD BE THE
PRIMARY SEVERE THREAT WITH THIS ACTIVITY.
