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

.DAY ONE...TODAY AND TONIGHT

RAIN AND THUNDERSTORMS WILL COVER MUCH OF ARKANSAS TODAY INTO
TONIGHT. VERY HIGH AMOUNTS OF MOISTURE WILL BE PRESENT SO THERE IS A
POTENTIAL FOR HEAVY RAINS IN SOME AREAS. LOCALIZED FLOODING OF LOW
LYING AND POOR DRAINAGE AREAS WILL BE POSSIBLE. LITTLE IF ANY
SEVERE WEATHER IS EXPECTED BUT A DAMAGING WIND INCIDENT OR TWO
DURING THE MID TO LATE AFTERNOON CANNOT BE RULED OUT.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

SHOWERS AND THUNDERSTORMS WILL DECREASE ON THURSDAY ALTHOUGH A
CHANCE OF ISOLATED FLOODING AND ISOLATED AFTERNOON WIND DAMAGE
WILL CONTINUE. ANOTHER UPPER LOW WILL MOVE ACROSS THE AREA ON
FRIDAY. THIS WILL BE ASSOCIATED WITH THE REMNANTS OF HURRICANE
HENRIETTE. AS A RESULT...TROPICAL MOISTURE WILL BE PRESENT AND THERE
COULD BE A BETTER CHANCE OF FLASH FLOODING.

A COLD FRONT WILL MOVE INTO ARKANSAS OVER THE WEEKEND THEN MAY STALL
SOMEWHERE IN THE AREA BEFORE MOVING OUT OF THE AREA ABOUT MONDAY. AT
THIS TIME...NO MORE THAN ISOLATED SEVERE WEATHER OR FLOODING IS
EXPECTED.
