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

.DAY ONE...TODAY AND TONIGHT.

SEVERE THUNDERSTORM.
RISK...LIMITED.
AREA...PRIMARILY EASTERN OKLAHOMA.
ONSET...LATE AFTERNOON THROUGH EARLY FRIDAY MORNING.

FLASH FLOOD.
RISK...LIMITED.
AREA...GENERALLY WEST OF A LINE FROM NOWATA TO MCALESTER.
ONSET...EVENING AND OVERNIGHT.

HEAVY RAIN.
RISK...LIMITED.
AREA...PRIMARILY EASTERN OKLAHOMA.
ONSET...ONGOING.

DISCUSSION...
SCATTERED THUNDERSTORMS ARE ONGOING THIS MORNING GENERALLY
SOUTHEAST OF INTERSTATE 44.  THESE STORMS WILL CONTINUE
EASTWARD AND LIKELY REMAIN BELOW SEVERE LIMITS...THOUGH PERIODS
OF GUSTY WINDS WILL BE POSSIBLE.  THUNDERSTORMS WILL AGAIN
DEVELOP ACROSS WESTERN OKLAHOMA AND SOUTHERN KANSAS LATER
THIS AFTERNOON AND SPREAD EASTWARD THROUGH THE OVERNIGHT HOURS.
SUFFICIENT INSTABILITY AND WIND SHEAR WILL EXIST FOR
THESE STORMS TO MAINTAIN SOME RISK OF SEVERE POTENTIAL INTO
EASTERN OKLAHOMA FROM THE LATE AFTERNOON THROUGH EARLY MORNING
HOURS ON FRIDAY.  AN INCREASING CONCERN IS THE EXPECTATION OF
ANOTHER ROUND OF HEAVY RAIN THROUGH TONIGHT.  WHILE THE EXACT
LOCATION OF THE HEAVIEST AMOUNTS IS UNCERTAIN...RECENT
RAINS WILL ALLOW FOR FLASH FLOODING TO DEVELOP RATHER QUICKLY.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
LOCAL SPOTTER ACTIVATION MAY BE NEEDED.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
FRIDAY THROUGH SUNDAY...SEVERE THUNDERSTORM POTENTIAL...HEAVY
RAIN POTENTIAL.
MONDAY...THUNDERSTORM POTENTIAL.
TUESDAY...NO HAZARDS.
WEDNESDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...
THE WEATHER PATTERN FROM FRIDAY THROUGH SUNDAY WILL SUPPORT
SEVERAL ROUNDS OF INTENSE THUNDERSTORMS ACROSS THE SOUTHERN
PLAINS.  SEVERE STORMS WILL DEVELOP ACROSS WESTERN OKLAHOMA
ON FRIDAY...AND SPREAD EASTWARD INTO PORTIONS OF EASTERN
OKLAHOMA FRIDAY EVENING AND OVERNIGHT.  SATURDAY APPEARS
TO THE BE A DAY OF WIDESPREAD SEVERE WEATHER ACROSS MUCH OF
THE CENTRAL AND SOUTHERN PLAINS...WITH SIGNIFICANT SEVERE
WEATHER LIKELY INCLUDING LONG TRACK TORNADOES.  THESE
STORMS HAVE POTENTIAL TO SPREAD INTO EASTERN OKLAHOMA AND
POSSIBLY WESTERN ARKANSAS.  SUNDAY WILL AGAIN BE A SEVERE
WEATHER DAY AS A COLD FRONT MOVES SLOWLY THROUGH THE AREA.
IN ADDITION TO THE SEVERE WEATHER POTENTIAL...SEVERAL ROUNDS
OF WIDESPREAD HEAVY RAINFALL ARE EXPECTED WHICH WILL MAKE
FLOODING LIKELY FOR PORTIONS OF THE AREA.

ANY WEEKEND PLANS NEED TO ACCOUNT FOR THE POTENTIAL FOR
SEVERE WEATHER.  THIS IS A POPULAR TIME FOR OUTDOOR FESTIVALS
AND THOSE EVENTS SHOULD TAKE EXTRA PRECAUTIONS TO ACCOUNT
FOR THE SEVERE WEATHER AND FLOODING POTENTIAL.
