AREAS AFFECTED...WEST TX AND THE TX PANHANDLE

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 221912Z - 222045Z

STORM COVERAGE WILL EXPAND AS STORMS INITIATE AND MOVE SEWD ACROSS
THE TX PANHANDLE AND WEST TX. LARGE HAIL AND ISOLATED WIND DAMAGE
WILL BE POSSIBLE AND A WW WILL BE ISSUED SHORTLY ACROSS THE REGION.

LATEST SFC ANALYSIS SHOWS A STATIONARY FRONTAL BOUNDARY EXTENDING
WSWWD FROM SW OK INTO ERN NM. SOUTH OF THE BOUNDARY...DEWPOINTS ARE
IN THE MID TO UPPER 60S F AND MODERATE INSTABILITY IS PRESENT.
THUNDERSTORMS ARE DEVELOPING ALONG THE BOUNDARY AND WILL LIKELY
INCREASE IN COVERAGE OVER THE NEXT FEW HOURS AS DESTABILIZATION
CONTINUES. FORECAST SOUNDINGS ACROSS THE TX PANHANDLE AND WEST TX
THIS AFTERNOON SHOW 0-6 KM SHEAR VALUES AROUND 25 KT SUGGESTING
SEVERE MULTICELLS AND/OR SUPERCELLS WILL BE POSSIBLE. IN
ADDITION...OBJECTIVE ANALYSIS SHOWS VERY STEEP LAPSE RATES IN PLACE
IN THE 7.5 TO 8.0 C/KM RANGE WHICH WILL BE FAVORABLE FOR HAIL AND
ISOLATED WIND DAMAGE WITH THE STRONGER CELLS.
