...FLASH FLOOD THREAT INCREASING INTO THE WEEKEND WITH THE POTENTIAL
   FOR MULTIPLE ROUNDS OF HEAVY RAINFALL...

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...TODAY AND TONIGHT.

FLASH FLOOD.
RISK...LIMITED.
AREA...EASTERN OKLAHOMA.
ONSET...LATE MORNING.

HEAVY RAIN.
RISK...LIMITED.
AREA...EASTERN OKLAHOMA.
ONSET...MID MORNING.

THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...LIMITED.
AREA...EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.

DISCUSSION...
AREAS OF RAIN WITH A FEW EMBEDDED THUNDERSTORMS WILL SPREAD INTO EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS TODAY IN ASSOCIATION WITH AN APPROACHING
UPPER LEVEL STORM SYSTEM. LOCALLY HEAVY RAINFALL COULD LEAD TO FLASH
FLOODING IN A FEW AREAS THROUGH TONIGHT.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION NOT EXPECTED.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY AND SUNDAY...SEVERE THUNDERSTORM AND HEAVY RAIN POTENTIAL.
MONDAY THROUGH THURSDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...
SEVERAL ROUNDS OF WIDESPREAD SHOWERS AND THUNDERSTORMS WILL BE
LIKELY SATURDAY AND SUNDAY. HEAVY RAIN...FLASH FLOODING...AND
MAIN STEM RIVER FLOODING WILL AGAIN IMPACT MUCH OF EASTERN OKLAHOMA
AND WESTERN ARKANSAS. A FLASH FLOOD WATCH REMAINS IN EFFECT FOR
ALL OF EASTERN OKLAHOMA THROUGH SUNDAY NIGHT...INCLUDING NORTHWEST
ARKANSAS SUNDAY AND SUNDAY NIGHT. ALTHOUGH A LIMITED THREAT FOR
SEVERE WEATHER WILL BE POSSIBLE BY SUNDAY...THIS WILL LIKELY BE
SECONDARY TO THE MUCH LARGER THREAT OF FLASH FLOODING.

THIS HEAVY RAINFALL WILL ALSO COINCIDE WITH THE HOLIDAY WEEKEND.
THE FLASH FLOODING POTENTIAL WILL POSE A HEIGHTENED THREAT TO
THOSE THAT PLAN OUTDOOR ACTIVITIES. UPDATED FORECASTS SHOULD BE
CLOSELY FOLLOWED AND PERSONS SHOULD BE READY TO TAKE ACTION SHOULD
FLOOD WARNINGS BE ISSUED FOR YOUR AREA. THIS IS ESPECIALLY TRUE
FOR THOSE PLANNING TO SPEND TIME NEAR AREA RIVERS AND LAKES AND
OTHER FLOOD PRONE AREAS WHERE LIFE THREATENING FLASH FLOODING
COULD DEVELOP.

THE CHANCE FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO NEXT WEEK
AS A MOIST AIR-MASS REMAINS IN PLACE. MULTIPLE ROUNDS OF RAIN WILL BE
POSSIBLE AS SEVERAL UPPER LEVEL DISTURBANCES TRAVERSE THE AREA.
ANY ADDITIONAL HEAVY RAINFALL WILL LIKELY LEAD TO ADDITIONAL FLASH
FLOODING.
