	AREA...EAST CENTRAL AND SOUTHEAST OKLAHOMA...WEST CENTRAL ARKANSAS.
	ONSET...ONGOING.

DISCUSSION...

BANDS OF THUNDERSTORMS CONTINUE TO MOVE EAST ACROSS EAST CENTRAL
AND SOUTHEAST OKLAHOMA...AS WELL AS NORTHWEST AND WEST CENTRAL
ARKANSAS THIS AFTERNOON. A LIMITED THREAT OF MARGINALLY SEVERE
WIND AND HAIL WILL CONTINUE MAINLY ACROSS SOUTHEAST OKLAHOMA ALONG
AND AHEAD OF A COLD FRONT WHERE THE ATMOSPHERE IS THE MOST UNSTABLE.

ANY ADDITIONAL RAINS THAT FALL THIS AFTERNOON AND EVENING OVER
AREAS THAT WERE AFFECTED BY HEAVY RAINS LAST NIGHT MAY HAVE
ADDITIONAL FLOODING ISSUES. THE MOST LIKELY AREA OF CONCERN IS
NORTHWEST AND WEST CENTRAL ARKANSAS...AND NEIGHBORING EAST CENTRAL

A VERY ENERGETIC UPPER LEVEL STORM SYSTEM IS FORECAST TO DIVE

MEANWHILE...LOW LEVEL MOISTURE WILL BE RETURNING NORTH AHEAD OF
LOW PRESSURE AND A COLD FRONT ACROSS THE REGION. THE COMBINATION
OF INCREASING LOW LEVEL MOISTURE...STRENGTHENING VERTICAL WIND
SHEAR...STRONG FORCING AND COOLING TEMPERATURES ALOFT WILL CREATE
CONDITIONS CONDUCIVE FOR SEVERE THUNDERSTORMS...DESPITE THE
UNFAVORABLE TIME OF DAY. AT THIS TIME...IT APPEARS THAT AT LEAST A
BROKEN LINE OF STRONG TO SEVERE STORMS IS LIKELY TO DEVELOP ALONG
THE COLD FRONT AS IT SWEEPS EAST ACROSS THE REGION. THE STRONG

TORNADOES. LARGE HAIL IS ALSO POSSIBLE IN THE STRONGER
