...THUNDERSTORM POTENTIAL INCREASES THIS EVENING WITH A COLD
FRONT...

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

.DAY ONE...TONIGHT.

DISCUSSION...

POCKETS OF DAMAGING WIND AND ISOLATED MARGINALLY SEVERE HAIL WILL
BE THE MAIN THREATS FROM STORMS THIS EVENING. THE AREA WITH THE
GREATEST THREAT FOR SEVERE WEATHER WILL BE NEAR THE KANSAS BORDER
ACROSS NORTHEAST OKLAHOMA. THE SEVERE WEATHER THREAT WILL DROP
CONSIDERABLY DURING THE OVERNIGHT HOURS AS THE ATMOSPHERE
STABILIZES.

A BROKEN LINE OF STORMS HAS ORGANIZED ALONG THE COLD FRONT ACROSS
KANSAS AND NW OK. THIS LINE OF STORMS WILL MOVE GENERALLY FROM NW TO
SE ACROSS THE REGION THIS EVENING AND TONIGHT. WEAK SHEAR AND
DECREASING INSTABILITY WITH TIME TONIGHT AND A TENDENCY FOR STORMS
TO BE UNDERCUT BY THE ADVANCING FRONT WILL MITIGATE THE OVERALL
SEVERE THREAT WITH THE FRONT. THUS...THE GREATEST POTENTIAL FOR
SEVERE WEATHER WILL BE ACROSS NORTHEAST OKLAHOMA AND CLOSER TO THE
KANSAS BORDER.

POCKETS OF LOCALLY HEAVY RAIN ARE EXPECTED...WITH BETWEEN AND INCH
AND 2 INCHES POSSIBLE ACROSS NORTHEAST OKLAHOMA AND NORTHWEST
ARKANSAS. IF THIS HEAVY RAIN FALLS ON AREAS THAT PICKED UP HEAVY
RAINS LAST NIGHT...SOME FLASH FLOODING COULD THEN OCCUR.

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

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY...THUNDERSTORM POTENTIAL.
SUNDAY...NO HAZARDS.
MONDAY THRU THURSDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...

POST FRONTAL THUNDERSTORM CHANCES WILL REMAIN POSSIBLE SATURDAY
MORNING OVER SOUTHEAST OKLAHOMA AND WESTERN ARKANSAS BEFORE THE
FRONT EXITS OFF TO THE SOUTH. HIGH PRESSURE WITH A COOLER AND
DRIER AIRMASS IS FORECAST TO FILTER INTO THE REGION BEHIND THE
DEPARTING COLD FRONT THROUGH THE WEEKEND. THUNDERSTORM CHANCES
RETURN NEXT WEEK AS ANOTHER LOW PRESSURE SYSTEM AND FRONTAL
BOUNDARY APPROACH THE REGION.
