.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT
BIG FOCUS IN THE NEXT 12 TO 24 HOURS WILL BE ON THE SURFACE LOW

DISCRETE CELLS WILL BE POSSIBLE THROUGH THE LATE AFTERNOON AND EARLY
EVENING AHEAD OF THE SYSTEM...THINGS WILL CONTINUE TO ORGANIZE INTO
LINE SEGMENTS.

SEVERE STORMS WILL BE POSSIBLE THROUGH THE AFTERNOON AND EVENING AS
THE FRONT AND ASSOCIATED CONVECTION SWEEP NORTHEASTWARD ACROSS

POSSIBILITY OF SEVERE THUNDERSTORMS...IT APPEARS THE AREA WITH THE
GREATEST LIKELIHOOD WILL BE GENERALLY EAST OF A LINE FROM FLIPPIN...
TO HOT SPRINGS...TO ARKADELPHIA. IN THIS AREA...MOISTURE RETURN HAS
BEEN THE GREATEST...WITH DEWPOINTS IN THE MID 50S TO NEAR 60 DEGREES

VALLEY.

AFTER THE FRONT EXITS THE AREA LATE TONIGHT/EARLY THURSDAY
MORNING...COOLER AND MUCH DRIER AIR WILL BLOW IN ON CONTINUED
SOUTHWEST SURFACE FLOW. WINDS MAY BE A LITTLE GUSTY OVER THE DELTA
REGION/PRAIRIES OF EASTERN ARKANSAS DURING THE DAY.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR A LARGE PART OF ARKANSAS.

A POTENT STORM SYSTEM CONTINUES TO MOVE TOWARDS THE STATE. THIS WILL
BRING CHANCES FOR STRONG TO SEVERE THUNDERSTORMS TO ARKANSAS THIS
AFTERNOON AND EVENING. A SLIGHT RISK OF SEVERE THUNDERSTORMS
CONTINUES ACROSS ALL OF ARKANSAS TODAY. A SEVERE THUNDERSTORM WATCH
HAS BEEN ISSUED FOR PARTS OF WEST ARKANSAS.

A STRONG UPPER LEVEL LOW WILL PUSH NORTHEAST THIS AFTERNOON AND
EVENING OVER KANSAS AND MISSOURI. SURFACE LOW PRESSURE CONTINUES TO
DEVELOP AHEAD OF THIS UPPER LOW OVER TEXAS AND OKLAHOMA AND
STRENGTHEN AS THIS SURFACE LOW PRESSURE LIFTS NORTHEAST INTO EASTERN
KANSAS AND WESTERN MISSOURI.

WARM...MOIST AIR WILL SURGE NORTH ACROSS THE NATURAL STATE THIS
AFTERNOON...ALLOWING THE ATMOSPHERE TO BECOME INCREASINGLY UNSTABLE.
THUNDERSTORMS WILL MOVE RAPIDLY EAST INTO WESTERN ARKANSAS EARLY
THIS AFTERNOON. THUNDERSTORMS WILL BECOME MORE NUMEROUS THIS
EVENING AS THESE STORMS PUSH EAST INTO CENTRAL AND NORTHERN ARKANSAS
