AREAS AFFECTED...TX PANHANDLE
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 252048Z - 252315Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...CONVECTIVE INITIATION ALONG A FRONTAL ZONE APPEARS
INCREASINGLY LIKELY BETWEEN 4-7PM CDT (21-00Z). LARGE HAIL APPEARS
TO BE THE PRIMARY THREAT, ALTHOUGH THE RISK FOR SEVERE GUSTS WILL
INCREASE DURING THE EVENING.
DISCUSSION...VISIBLE-SATELLITE IMAGERY SHOWS A GRADUAL CLUMPING OF
CUMULUS ALONG A FRONT DRAPED FROM SOUTHWEST TO NORTHEAST ACROSS THE
TX PANHANDLE. A PATCH OF CIRRUS OVER EASTERN NM APPEARS ASSOCIATED
WITH THE LEADING EDGE OF APPRECIABLE LARGE-SCALE ASCENT FROM A
DESERT SOUTHWEST UPPER TROUGH. AS CONTINUED HEATING OF A
MOIST/DESTABILIZING BOUNDARY LAYER OCCURS THIS THIS AFTERNOON,
EXPECTING ADDITIONAL EROSION OF CONVECTIVE INHIBITION ALONG THE
BOUNDARY. MODIFYING THE 18Z AMARILLO RAOB FOR LOWER 80S DEG F
TEMPERATURES AND LOWER 60S DEWPOINTS, YIELDS AROUND 2400 J/KG MLCAPE
AND MINIMAL MLCINH (-35 J/KG).
MODELS CONTINUE TO VARY REGARDING TIMING/COVERAGE OF STORM
DEVELOPMENT WITHIN THIS MESOSCALE CORRIDOR. HOWEVER, CLOUD TRENDS
AND FORECASTER EXPERIENCE IMPLY AT LEAST ISOLATED TO WIDELY
SCATTERED STORM DEVELOPMENT OVER THE NEXT 3 OR SO HOURS. DEPENDING
ON TIMING/COVERAGE OF DEVELOPING STORMS, A SEVERE THUNDERSTORM WATCH
WILL BE CONSIDERED.
