AREAS AFFECTED...WRN AND CNTRL TX

CONCERNING...SEVERE THUNDERSTORM WATCH 333...

VALID 260049Z - 260215Z

STORMS ARE CURRENTLY EXPANDING IN COVERAGE IN THE WRN PART OF WW
333. THE STRONGER CELLS WILL LIKELY HAVE A THREAT FOR LARGE HAIL AND
WIND DAMAGE.

SFC ANALYSIS SHOWS A FRONTAL BOUNDARY EXTENDING FROM SOUTH OF
MIDLAND TO NEAR SAN ANGELO WHERE STRONG LOW-LEVEL CONVERGENCE
EXISTS. A MOIST AXIS EXTENDS NWD ACROSS WCNTRL TX WITH SFC DEWPOINTS
IN THE 60S F WHICH COMBINED WITH THE HOT TEMPERATURES IS RESULTING
IN MODERATE INSTABILITY SOUTH OF THE FRONT. AS STORMS CONTINUE TO
INITIATE AND EXPAND IN COVERAGE...STEEP LAPSE RATES AND 0-6 KM SHEAR
VALUES WILL BE SUFFICIENT FOR SEVERE MULTICELL STORMS WITH LARGE
HAIL AND WIND DAMAGE. IR IMAGERY SHOWS COOLING TOPS WITH THE CLUSTER
OF STORMS OVER WCNTRL TX WHICH SUGGESTS AN MCS IS CURRENTLY
DEVELOPING OVER WCNTRL TX. THE MCS SHOULD MOVE SLOWLY SEWD INTO THE
TX HILL COUNTRY OVER THE NEXT 1-3 HOURS WITH A SEVERE THREAT
CONTINUING.
