1003 PM CDT THU MAY 22 2025
AREAS AFFECTED...CENTRAL TX
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 230303Z - 230430Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...A SEVERE WIND THREAT WITH A SMALL MCS SHOULD PERSIST
THROUGH MIDNIGHT, WITH LESS CONFIDENCE IN LONGEVITY OVERNIGHT.
DISCUSSION...THE COLDEST IR CLOUD TOPS OF THE EVENING WERE RECENTLY
SAMPLED WITH A LINEAR CLUSTER/SMALL MCS THAT HAS BEEN PROGRESSING
SOUTHEASTWARD ACROSS THE BIG COUNTRY AND CONCHO VALLEY. THIS
CORRELATED WITH THE STRONGEST MEASURED SEVERE GUST THUS FAR OF 65
KTS AT KETN, AND LIKELY A RESULT OF IMPINGING ON RICHER LOW-LEVEL
MOISTURE ADVECTING NORTHWESTWARD FROM CENTRAL TX. A 30-35 KT
LOW-LEVEL JET AS SAMPLED BY THE GRK VWP COULD SUPPORT SPORADIC
SEVERE GUSTS PERSISTING SOUTHEASTWARD DURING THE NEXT 2-3 HOURS.
CONSENSUS OF 00Z CAM GUIDANCE INFERRED A MORE ABRUPT WEAKENING OF
THE CLUSTER, BUT THE RRFS APPEARS TO HAVE A BETTER HANDLE ON HOW IT
IS EVOLVING AND SUPPORTS A FEW MORE HOURS OF SEVERE THREAT. WITH
INSTABILITY WEAKENING OVERNIGHT, EXPECTATION IS STILL FOR THIS MCS
TO DIMINISH INTO THE EARLY MORNING.
