NWS STORM PREDICTION CENTER NORMAN OK
0100 AM CDT FRI MAY 01 2026
AREAS AFFECTED...PARTS OF SOUTH-CENTRAL TX
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 010600Z - 010830Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A THREAT FOR ISOLATED HAIL AND DAMAGING GUSTS WILL
CONTINUE OVERNIGHT.
DISCUSSION...STRONG THUNDERSTORMS ARE ONGOING ACROSS PARTS OF
SOUTH-CENTRAL TX AS OF 06 UTC, WITH OCCASIONAL ELEVATED SUPERCELLS
NOTED. THIS ACTIVITY CONTINUES TO DEVELOP NORTH OF A NEARLY
STATIONARY SURFACE FRONT, AND MAY PERSIST THROUGH MUCH OF THE
OVERNIGHT AS A MID/UPPER-LEVEL SHORTWAVE TROUGH APPROACHES THE
REGION FROM NORTHERN MEXICO.
WHILE MIDLEVEL LAPSE RATES (AS OBSERVED IN THE 00Z CRP SOUNDING AND
ANALYZED BY THE RAP) ARE NOT PARTICULARLY STEEP, RICH MOISTURE ABOVE
THE FRONTAL INVERSION IS SUPPORTING MUCAPE OF 500-1500 J/KG WHERE
STORMS ARE ONGOING. STRONG MID/UPPER-LEVEL WESTERLY FLOW IS
RESULTING IN EFFECTIVE SHEAR OF 60+ KT, MORE THAN SUFFICIENT FOR
ORGANIZED CONVECTION. LARGE HAIL AND LOCALIZED DAMAGING GUSTS WILL
CONTINUE TO BE POSSIBLE WITH THE STRONGEST STORMS OVERNIGHT. A
RECENT ELEVATED STORM WITH HAIL NEAR HOUSTON SUGGESTS THAT SOME
SEVERE POTENTIAL MAY EXTEND FARTHER NORTH THAN ANALYZED MUCAPE WOULD
INDICATE, THOUGH STORMS THAT TRACK FARTHER SOUTH (CLOSER TO THE
FRONT) WILL HAVE ACCESS TO STRONGER BUOYANCY, AND PERHAPS A
LOCALIZED VERY LARGE HAIL THREAT.
