AREAS AFFECTED...PARTS OF SOUTH TEXAS
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 302231Z - 010000Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...AN ISOLATED SEVERE HAIL AND WIND RISK WILL PERSIST FOR
ANOTHER COUPLE HOURS. CURRENT THINKING IS THAT THE OVERALL SEVERE
RISK WILL REMAIN TOO ISOLATED FOR A WATCH.
DISCUSSION...AN ISOLATED/DISCRETE SUPERCELL HAS DEVELOPED WITHIN A
WARM, MOIST, AND UNCAPPED ENVIRONMENT ACROSS SOUTH TX. GIVEN WEAK
FORCING FOR ASCENT, OVERALL STORM COVERAGE IS EXPECTED TO REMAIN
ISOLATED. HOWEVER, AROUND 3000 J/KG MLCAPE AND AN ELONGATED/STRAIGHT
HODOGRAPH (SAMPLED BY EWX VWP) WILL CONTINUE TO SUPPORT AN ISOLATED
SUPERCELL OR TWO -- CAPABLE OF PRODUCING SEVERE HAIL AND LOCALLY
DAMAGING GUSTS. THIS THREAT SHOULD PERSIST FOR ANOTHER COUPLE HOURS,
BEFORE THE BOUNDARY LAYER NOCTURNALLY STABILIZES. GIVEN THE ISOLATED
NATURE OF THE THREAT, A WATCH IS NOT EXPECTED.
