...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE SOUTHERN PLAINS...
..SUMMARY
THUNDERSTORMS WITH ISOLATED SEVERE WIND GUSTS WILL BE POSSIBLE ON
THURSDAY ACROSS PARTS OF THE SOUTHERN PLAINS.
..SOUTHERN PLAINS
AN UPPER-LEVEL TROUGH WILL MOVE EASTWARD ACROSS THE SOUTH-CENTRAL
U.S. ON THURSDAY, AS A COLD FRONT ADVANCES SOUTHEASTWARD ACROSS THE
SOUTHERN PLAINS. SURFACE HEATING AND INCREASING LOW-LEVEL
CONVERGENCE WILL RESULT IN SCATTERED THUNDERSTORM DEVELOPMENT NEAR
THE FRONT. THUNDERSTORMS WILL GRADUALLY INCREASE IN COVERAGE DURING
THE AFTERNOON, MOVING EASTWARD ACROSS A ZONE FROM SOUTHWEST, CENTRAL
AND NORTHEAST TEXAS INTO SOUTHEAST OKLAHOMA. AHEAD OF THE FRONT,
SURFACE DEWPOINTS IN THE LOWER TO MID 70S F MAY RESULT IN MODERATE
DESTABILIZATION ACROSS PARTS OF THE MOIST AIRMASS. STORMS THAT
DEVELOP WITHIN THESE POCKETS OF STRONGER INSTABILITY COULD BE
ASSOCIATED WITH AN ISOLATED WIND-DAMAGE THREAT, MAINLY AS LOW-LEVEL
LAPSE RATES BECOME STEEP IN THE LATE AFTERNOON. HOWEVER, DEEP-LAYER
SHEAR IS FORECAST TO REMAIN RELATIVELY WEAK, WHICH WILL MARGINALIZE
ANY SEVERE THREAT.
