0544 PM CDT TUE JUN 17 2025
AREAS AFFECTED...PARTS OF THE TEXAS SOUTH PLAINS AND PANHANDLE INTO
FAR SOUTHWEST OKLAHOMA
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 172244Z - 180045Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...SEVERE WIND GUSTS WILL LIKELY ACCOMPANY ANY HIGH-BASED
THUNDERSTORMS THAT CAN INITIATE. STORM DEVELOPMENT/COVERAGE IS
UNCERTAIN, THOUGH TRENDS ARE BEING MONITORED FOR A POSSIBLE WATCH.
DISCUSSION...VISIBLE SATELLITE IMAGERY SHOWS INCREASINGLY AGITATED
HIGH-BASED CUMULUS DEVELOPING ALONG A DRYLINE EXTENDING ACROSS THE
TX SOUTH PLAINS. RADAR DATA FROM LBB ALSO SHOWS CONTINUED ATTEMPTS
AT CONVECTIVE INITIATION WITHIN THE ZONE OF LOW-LEVEL ASCENT. IF A
COUPLE STORMS CAN DEVELOP WITHIN THIS CORRIDOR, A DEEPLY MIXED
BOUNDARY LAYER (CHARACTERIZED BY AN INVERTED-V SOUNDING) AND
SUFFICIENT INSTABILITY WOULD PROMOTE SEVERE DOWNBURSTS (AND POSSIBLY
SOME SEVERE HAIL) WITH ANY SUSTAINED HIGH-BASED STORMS. STORM
DEVELOPMENT/SUSTENANCE AND OVERALL COVERAGE IS SOMEWHAT UNCERTAIN,
THOUGH TRENDS ARE BEING MONITORED FOR A POSSIBLE WATCH.
