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

.DAY ONE...THIS AFTERNOON AND TONIGHT
SHOWERS AND THUNDERSTORMS COULD DEVELOP ANYWHERE IN THE AREA THIS
AFTERNOON. THE MORE FAVORED AREAS FOR DEVELOPMENT WILL BE NEAR A
WEAKENING WARM FRONT IN THE NORTH AND NEAR THE REMNANTS OF AN
OVERNIGHT THUNDERSTORM COMPLEX...WHICH COULD SET UP IN SOUTHERN
ARKANSAS.

A COMPLEX OF THUNDERSTORMS OR TWO MAY DEVELOP TONIGHT AND COULD MOVE
ACROSS PARTS OF THE AREA.

ISOLATED SEVERE THUNDERSTORMS WILL BE POSSIBLE THIS AFTERNOON AND
TONIGHT. THE MAIN SEVERE WEATHER WILL BE LARGE HAIL AND DAMAGING
WIND. LOCALLY HEAVY RAIN WILL ALSO BE POSSIBLE BUT LITTLE FLOODING
IS EXPECTED AT THIS TIME.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

UPPER LEVEL LOWS WILL MOVE ACROSS ARKANSAS AT TIMES THROUGH AT LEAST
FRIDAY NIGHT OR SATURDAY. A COLD FRONT WILL MOVE INTO THE STATE ON
THURSDAY WILL HOLD NEARLY STATIONARY IN NORTHERN ARKANSAS OR
SOUTHERN MISSOURI. PRESENT INDICATIONS FAVOR THIS FRONT EVENTUALLY
MOVING TO THE SOUTH ACROSS THE STATE FRIDAY AND FRIDAY NIGHT AND
MOVING TO THE SOUTH OF ARKANSAS BY SATURDAY.

PERIODS OF SHOWERS AND THUNDERSTORMS WILL AFFECT ARKANSAS FROM
THURSDAY THROUGH EARLY SATURDAY. THE GENERAL TENDENCY WILL BE FOR
THUNDERSTORMS TO DEVELOP DURING THE MID TO LATE AFTERNOON AND
CONTINUE INTO THE EVENING. COMPLEXES OF THUNDERSTORMS MAY DEVELOP
DURING THE EVENING AND CONTINUE THROUGH MUCH OF THE NIGHT WITH A
WEAKENING TREND LATE AT NIGHT AND IN THE MORNING.

A FEW SEVERE THUNDERSTORMS WILL BE POSSIBLE THROUGH THE PERIOD WITH
LARGE HAIL AND DAMAGING WIND BEING THE MAIN SEVERE WEATHER. ALSO...
HEAVY RAINS WILL BE POSSIBLE. THE NIGHTTIME THUNDERSTORM COMPLEXES
COULD RESULT IN THUNDERSTORMS MOVING OVER THE SAME AREAS AND
PRODUCING HEAVY RAINS WHICH COULD CAUSE FLASH FLOODING.

IT APPEARS THAT NORTHERN ARKANSAS WILL BE THE MOST VULNERABLE FOR
HEAVY RAINS AND FLOODING ESPECIALLY TONIGHT AND THURSDAY NIGHT.

THUNDERSTORMS SHOULD DECREASE SATURDAY AND LITTLE RAIN IS EXPECTED
THROUGH SUNDAY. ANOTHER CHANCE OF SHOWERS AND THUNDERSTORMS WILL
RETURN ON MONDAY. LITTLE OR NO SEVERE WEATHER IS EXPECTED AT THIS
TIME FROM SATURDAY THROUGH TUESDAY.

.SPOTTER ACTIVATION STATEMENT...

SPOTTER ACTIVATION MAY BE REQUIRED THIS AFTERNOON AND TONIGHT IN
SOME AREAS.
