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

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS ARE EXPECTED TO RAPIDLY DEVELOP DURING THE MID AND
LATE AFTERNOON HOURS...ALONG AND AHEAD OF A SLOW MOVING SURFACE
BOUNDARY...LOCATED ACROSS CENTRAL OKLAHOMA...TO WESTERN MISSOURI.

THE STORMS ARE EXPECTED TO MOVE EASTWARD DURING THE LATE AFTERNOON
HOURS...WITH THE STRONGEST STORMS AFFECTING AREAS ALONG AND THE
NORTH OF A LINE FROM MENA...TO MOUNTAIN HOME.  THE STRONGEST STORMS
WILL AFFECT THIS AREA THROUGH LATE EVENING...AND WILL BE CAPABLE OF
PRODUCING LARGE HAIL...WIDESPREAD DAMAGING WIND GUSTS...AND
TORNADOES.

AS THE STORMS PROGRESS EASTWARD DURING LATE EVENING AND EARLY
MORNING HOURS...ACROSS CENTRAL AND NORTHEAST SECTIONS OF
ARKANSAS...SOME WEAKENING WILL OCCUR. HOWEVER...DAMAGING WIND GUSTS
WILL STILL BE POSSIBLE WITH THE STRONGEST STORMS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

CHANCES FOR SHOWERS AND THUNDERSTORMS WILL INCREASE AREA WIDE FOR
TUESDAY AND TUESDAY NIGHT AS THE POTENT STORM SYSTEM TO THE WEST
MOVES OVER ARKANSAS. DAMAGING WINDS AND LARGE HAIL WILL BE THE
MAIN THREATS WITH THE STRONGEST STORMS. THE THREAT FOR TORNADOES
WILL BE SOMEWHAT LIMITED DUE TO LACK OF SIGNIFICANT LOW LEVEL SHEAR.
HOWEVER...CANNOT COMPLETELY RULE OUT AN ISOLATED TORNADO...ESPECIALLY
IF THERE IS LOCALIZED INCREASE IN LOW LEVEL SHEAR ACROSS SOME
PORTION OF THE STATE. HEAVY RAINFALL WILL ALSO BE POSSIBLE AS
SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE
DURING THE DAY ON TUESDAY AND THROUGH TUESDAY NIGHT. AS A
RESULT...LOCALIZED FLASH FLOODING WILL ALSO BE POSSIBLE.

CHANCES FOR SHOWERS AND THUNDERSTORMS WILL DECREASE FOR THE MIDDLE
OF THE WEEK AS WEAK HIGH PRESSURE MOVES OVER THE REGION. HOWEVER...A
COLD FRONT WILL ATTEMPT TO MOVE INTO THE STATE THURSDAY INTO
FRIDAY. THIS FRONT COULD TRIGGER SOME SHOWERS AND THUNDERSTORMS
THURSDAY AND FRIDAY. HOWEVER...THE THREAT FOR WIDESPREAD HAZARDOUS
WEATHER LOOKS LIMITED AT THIS TIME THIS FAR OUT.
