...WINDY TODAY WITH A MORE ACTIVE PATTERN SHAPING UP FOR EARLY NEXT
WEEK...

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...SOUTHEAST OKLAHOMA AND WEST CENTRAL ARKANSAS.

RISK...LIMITED.
AREA...NORTHEAST OKLAHOMA.
ONSET...ONGOING.

FIRE WEATHER DANGER.
RISK...ELEVATED.
AREA...NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS.
ONSET...ONGOING.

DISCUSSION...
BREEZY SOUTH WINDS WILL COMBINE WITH WARM TEMPERATURES AND LOW
AFTERNOON RELATIVE HUMIDITIES TO PRODUCE AN ELEVATED FIRE DANGER
TODAY FOR PARTS OF NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS.

IN ADDITION...ISOLATED THUNDERSTORMS WILL BE POSSIBLE ACROSS
PORTIONS OF SOUTHEAST OKLAHOMA AND WEST CENTRAL ARKANSAS THIS
AFTERNOON...MAINLY SOUTH OF A LINE FROM MCALESTER TO FORT SMITH.
WIDESPREAD SEVERE WEATHER IS NOT EXPECTED WITH THESE STORMS...BUT
THE PRESENCE OF AMPLE INSTABILITY MAKES LARGE HAIL AND DAMAGING
WINDS POSSIBLE WITH ANY STORMS THAT CAN DEVELOP.

BOTH THE FIRE DANGER AND THE SEVERE WEATHER THREAT WILL DECREASE
MID EVENING.

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

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.
SUNDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL...HEAVY RAIN POTENTIAL.
MONDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL...HEAVY RAIN POTENTIAL.
TUESDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.
WEDNESDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.
THURSDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.

EXTENDED DISCUSSION...
AN ACTIVE SOUTHWESTERLY UPPER FLOW PATTERN WILL DEVELOP OVER THE
WEEKEND AND PERSIST THROUGH NEXT WEEK. IMPROVING LOW-LEVEL
MOISTURE...COMBINED WITH NUMEROUS UPPER LEVEL DISTURBANCES AND A
NEARBY SURFACE BOUNDARY WILL RESULT IN PERIODIC CHANCES OF SHOWERS
AND THUNDERSTORMS MAINLY LATE THIS WEEKEND AND THROUGH MUCH OF NEXT
WEEK. THE BEST CHANCES FOR SIGNIFICANT RAINFALL APPEARS TO BE IN THE
MONDAY TO TUESDAY TIMEFRAME...WHEN 2 TO 4 INCHES OF RAIN WILL BE
POSSIBLE. SOME SEVERE WEATHER WILL BE POSSIBLE AS WELL...BUT THE
MAIN THREAT SHOULD BE HEAVY RAINFALL. WIDESPREAD RAINFALL AMOUNTS
OF THIS MAGNITUDE WILL LEAD TO AN INCREASED THREAT OF RIVER
FLOODING...WITH THE POSSIBILITY OF RIVERS RISING AND CRESTING
ABOVE FLOOD STAGE. THIS WOULD MOST LIKELY OCCUR FROM THE MIDDLE TO
LATTER PART OF NEXT WEEK.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
EMERGENCY MANAGERS SHOULD MONITOR THE LATEST FORECAST FOR THE
POSSIBILITY OF SEVERE WEATHER AND RIVER AND OVERLAND FLOODING
LATE IN THE WEEKEND AND INTO NEXT WEEK.
