...SEVERE STORMS AND FLASH FLOODING POSSIBLE THIS AFTERNOON AND OVERNIGHT...

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...TODAY AND TONIGHT.

AREA...FAR SOUTHEAST OKLAHOMA.
ONSET...ONGOING.

SEVERE THUNDERSTORM.

AREA..EASTERN OKLAHOMA AND WEST CENTRAL ARKANSAS.
ONSET...ONGOING.

AREA AT GREATEST RISK...FAR SOUTHEAST OKLAHOMA AND WESTERN ARKANSAS.

DISCUSSION...
A WARM FRONT REMAINS IN CLOSE PROXIMITY TO THE AREA ACROSS NORTH
TEXAS. FAIRLY STRONG INSTABILITY EXTENDS UP AND OVER THE FRONT
INTO SOUTHEAST OKLAHOMA AND WEST CENTRAL ARKANSAS. ONGOING
THUNDERSTORMS MOVING INTO THE REGION FROM THE WEST WILL ENCOUNTER THIS
SLIGHTLY ELEVATED INSTABILITY. ENHANCED BY STEEP LAPS RATES...
STORMS WILL HAVE THE POTENTIAL TO ATTAIN SEVERE LIMITS. LARGE HAIL
AND DAMAGING WINDS WILL BE THE PRIMARY THREATS IN OUR AREA.
HOWEVER... DUE TO THE PROXIMITY OF THE FRONT... AND INCREASED
SURFACE HEATING DURING THE AFTERNOON... THERE WILL BE A LIMITED
OPPORTUNITY FOR STORMS TO BECOME SURFACE BASED... THUS CREATING A
LIMITED TORNADO POTENTIAL ACROSS EXTREME SOUTHEAST OKLAHOMA AND
SOUTHWEST ARKANSAS.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION MAY BE NEEDED.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
WEDNESDAY...THUNDERSTORM POTENTIAL.
THURSDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...
THUNDERSTORMS WILL BE POSSIBLE THROUGHOUT THE ENTIRE FORECAST PERIOD. A
WARM FRONT WILL MOVE NORTHWARD ACROSS THE AREA WEDNESDAY AND
THURSDAY. SURFACE BASED INSTABILITY WILL INCREASE TO THE SOUTH OF
THE WARM FRONT. STRONG TO SEVERE THUNDERSTORMS WILL BE POSSIBLE...ESPECIALLY
ON THURSDAY.

ANOTHER FRONTAL SYSTEM WILL EFFECT THE AREA FROM LATE FRIDAY INTO
EARLY NEXT WEEK... FIRST AS A COLD FRONTAL PASSAGE... AND THEN WITH ITS
RETURN NORTHWARD AS A WARM FRONT.
