...A DANGEROUS SEVERE WEATHER EPISODE ACROSS ARKANSAS IS EXPECTED
FOR THURSDAY...

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

.DAY ONE...TONIGHT

EXCESSIVE RUNOFF FROM HEAVY RAINS OVER THE LAST TWO WEEKS WILL
CONTINUE TO CAUSE FLOODING OF RIVERS...STREAMS AND LOW WATER
CROSSINGS ACROSS MUCH OF CENTRAL...EASTERN AND SOUTHERN ARKANSAS.
THIS INCLUDES THE BLACK RIVER...THE LOWER WHITE RIVER...THE CACHE
AND OUACHITA RIVERS.

ADDITIONAL HEAVY RAINFALL IS POSSIBLE THROUGH THE NIGHT...AS STRONG
THUNDERSTORMS MOVE THROUGH THE AREA. ANY LOCALIZED HEAVY RAINFALL
WILL HAVE THE POTENTIAL TO BE EXCESSIVE.

ALSO...SOME OF THE THUNDERSTORMS WILL BE SEVERE...PRODUCING LARGE
HAIL AND DAMAGING WINDS. THE GREATEST THREAT FOR SEVERE
THUNDERSTORMS TONIGHT WILL OCCUR WEST OF A LINE FROM HARRISON...TO
HOT SPRINGS...TO CAMDEN.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

THURSDAY.

A COLD FRONT WILL MOVE EAST ACROSS THE STATE ON THURSDAY. ABUNDANT
MOISTURE WILL BE IN PLACE AHEAD OF THE FRONT...AS WELL AS
SUFFICIENT INSTABILITY FOR THUNDERSTORM DEVELOPMENT.  THESE
CONDITIONS...ALONG WITH A POWERFUL MID AND UPPER LEVEL WIND
FIELD...WILL PROMOTE THE DEVELOPMENT OF LONG-LIVED...SUPERCELL
THUNDERSTORMS.

IN ADDITION TO SEVERE WEATHER...HEAVY RAIN WILL BE POSSIBLE. WITH
THE GROUND NEARLY SATURATED IN MOST AREAS...IT WILL NOT TAKE A LOT
OF RAIN TO PRODUCE ADDITIONAL FLASH FLOODING. ANY ADDITIONAL
RAINFALL WILL ALSO AFFECT RIVER FLOODING CONDITIONS.

RESIDENTS ACROSS ARKANSAS ARE ADVISED TO REVIEW SEVERE WEATHER...AND
