AREAS AFFECTED...SE TX

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 132037Z - 132230Z

THUNDERSTORMS WILL CONTINUE TO EXPAND IN COVERAGE ACROSS SE TX OVER
THE NEXT FEW HOURS. ISOLATED WIND DAMAGE AND HAIL WILL BE POSSIBLE
WITH THE ACTIVITY.

LATEST SFC ANALYSIS SHOWS A FRONTAL BOUNDARY EXTENDING NORTHWEST TO
SOUTHEAST FROM NEAR WACO INTO THE HOUSTON AREA. SFC DEWPOINTS ALONG
AND NORTH OF THE BOUNDARY RANGE FROM THE MID 60S TO LOWER 70S F. THE
STORMS ARE DEVELOPING ALONG AN AXIS OF MODERATE INSTABILITY JUST
AHEAD OF AN APPROACHING SHORTWAVE TROUGH MOVING SWD ACROSS EAST TX.
FORECAST SOUNDINGS ACROSS THE REGION THIS AFTERNOON SHOW
UNIDIRECTIONAL WIND PROFILES IN PLACE WITH STRONG SPEED SHEAR MAINLY
ABOVE 700 MB. THIS SUGGESTS SUPERCELLS WILL BE POSSIBLE WITH STORMS
THAT REMAIN DISCRETE. THE LARGE TEMP-DEWPOINT SPREADS SUGGEST WIND
DAMAGE WILL BE THE MAIN THREAT ALTHOUGH LARGE HAIL WILL ALSO BE
POSSIBLE WITH THE STRONGER CELLS.
