BE LARGE HAIL. HOWEVER...THERE WILL BE A SMALL RISK OF A TORNADO ACROSS
EXTREME SOUTHEAST OKLAHOMA IF A THUNDERSTORM CAN BECOME SURFACE BASED

EXTENDED DISCUSSION...
THE THREAT FOR SHOWERS AND THUNDERSTORMS IS EXPECTED TO END
BY WEDNESDAY AFTERNOON AS THE MID-LEVEL SHORTWAVE MOVES EAST OF
THE AREA.

THE WEATHER PATTERN WILL REMAIN UNSETTLED INTO EARLY NEXT WEEK
AS SURFACE FRONTAL BOUNDARIES LINGER IN THE AREA AND A SERIES OF
UPPER LEVEL DISTURBANCES MOVE ACROSS THE REGION. THE POTENTIAL
FOR STRONG TO SEVERE THUNDERSTORMS WILL BE HIGHEST THURSDAY
INTO FRIDAY AS THE AIRMASS ACROSS THE AREA BECOMES INCREASINGLY
UNSTABLE AS A WARM FRONT MOVES NORTH OF THE AREA IN ADVANCE OF A
COLD FRONT THAT WILL MOVE THROUGH FRIDAY NIGHT.
