DISCUSSION...
THE CHANCES OF SHOWERS AND THUNDERSTORMS WILL INCREASE DRAMATICALLY
THIS AFTERNOON AND INTO TONIGHT AS A COLD FRONT NOW ACROSS CENTRAL
KANSAS MOVES INTO NORTHEAST OKLAHOMA LATE THIS AFTERNOON
AND EVENING. SHOWERS AND THUNDERSTORMS ARE ALREADY OCCURRING
IN ADVANCE OF THE COLD FRONT ACROSS NORTH-CENTRAL OKLAHOMA
AND SOUTHEAST KANSAS. THIS ACTIVITY WILL INCREASE LATER THIS
AFTERNOON AS THE COLD FRONT MOVES INTO THE INCREASINGLY UNSTABLE
AIRMASS IN PLACE ACROSS EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.
SOME OF THE THUNDERSTORMS COULD BECOME SEVERE LATE THIS AFTERNOON
AND EVENING IN THE VICINITY OF THE COLD FRONT.  WIND GUSTS TO 70
MPH WILL BE THE MAIN CONCERN. HOWEVER...THERE WILL BE ADEQUATE DEEP
LAYER SHEAR FOR SUPERCELL DEVELOPMENT WITH A BRIEF TORNADO POSSIBLE.
THE THREAT FOR SEVERE THUNDERSTORMS IS EXPECTED TO DIMINISH A FEW HOURS
AFTER SUNSET WITH THE LOSS OF DAYTIME HEATING. HOWEVER...SHOWERS AND
THUNDERSTORMS WILL CONTINUE THROUGH THE NIGHT AS THE COLD FRONT SLOWLY
SAGS TO THE SOUTH ACROSS THE AREA.

HEAVY RAIN WILL ALSO BE A CONCERN WITH THE PRECIPITABLE WATER APPROACHING
TWO INCHES. 1 TO 3 INCHES OF RAIN WILL BE POSSIBLE IN A SHORT PERIOD OF
TIME ACROSS PORTIONS OF NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS THROUGH
TONIGHT.
