NWS STORM PREDICTION CENTER NORMAN OK
0124 PM CDT TUE APR 14 2026
AREAS AFFECTED...PORTIONS OF THE TEXAS BIG BEND AND EDWARDS PLATEAU
INTO NORTHWEST TEXAS
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 141824Z - 142100Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...THUNDERSTORMS DEVELOPING ALONG/AHEAD OF A DRYLINE THIS
AFTERNOON WILL POSE A RISK FOR LARGE TO VERY LARGE HAIL AND PERHAPS
A TORNADO OR TWO. A WATCH WILL LIKELY BE NEEDED WITHIN THE NEXT
COUPLE OF HOURS.
DISCUSSION...LATEST REGIONAL RADAR IMAGERY AND GLM FLASH DATA
INDICATE ONGOING THUNDERSTORM DEVELOPMENT ACROSS THE CHISOS
MOUNTAINS WITHIN THE TEXAS BIG BEND REGION. ADDITIONAL THUNDERSTORM
DEVELOPMENT IS EXPECTED THIS AFTERNOON ALONG A DRYLINE ACROSS MUCH
OF WEST TEXAS AND ACROSS THE SIERRA DEL CARMEN IN NORTHERN MEXICO.
AHEAD OF THIS DRYLINE, SURFACE TEMPERATURES IN THE LOW/MID-80S F AND
DEWPOINTS IN THE MID-60S F UNDERNEATH STEEP MID-LEVEL LAPSE RATES
ARE SUPPORTING 1500-2500 J/KG MLCAPE (LOCALLY GREATER). EFFECTIVE
BULK SHEAR OF 35-45+ KTS AND STRAIGHT, ELONGATED HODOGRAPHS WILL
SUPPORT SUPERCELLS (BOTH LEFT- AND RIGHT-MOVING) CAPABLE OF LARGE TO
VERY LARGE HAIL OF 2-3+ INCHES IN DIAMETER AND SEVERE WIND GUSTS. A
GRADUALLY STRENGTHENING NOCTURNAL LOW-LEVEL JET WILL LIKELY SUPPORT
AT LEAST SOME INCREASE IN THE TORNADO THREAT LATER THIS EVENING,
ESPECIALLY WITH ANY PERSISTENT, DISCRETE SUPERCELL(S); HOWEVER, THE
CORE OF THE LOW-LEVEL JET IS FORECAST TO BE DISPLACED FARTHER TO THE
NORTHEAST. THUS, THE MAGNITUDE OF THE TORNADO THREAT REMAINS
SOMEWHAT UNCERTAIN AT THIS TIME. REGARDLESS, WATCH ISSUANCE WILL
LIKELY BE NEEDED BY 21Z.
WITH TIME, SOME GRADUAL UPSCALE GROWTH/CLUSTERING SHOULD OCCUR WITH
ONGOING STORMS, WITH AN ASSOCIATED INCREASE IN THE POTENTIAL FOR
SEVERE WIND GUSTS.
