.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM.
NORTHWEST ARKANSAS TERMINALS WILL HAVE THE GREATEST CHANCE AT
SEEING SHOWERS AND THUNDERSTORMS OVERNIGHT...BUT OVERALL THE
CHANCES ARE LOWER THAN THE PREVIOUS FEW NIGHTS. MVFR CEILINGS WILL
BE LIKELY FOR A FEW HOURS LATE TONIGHT AND SATURDAY MORNING BEFORE
IMPROVING TO VFR BY SATURDAY AFTERNOON.

.PREV DISCUSSION... /ISSUED 246 PM CDT FRI AUG 9 2013/

DISCUSSION...
WEAK AND SOMEWHAT DIFFUSE FRONTAL BOUNDARY LOCATED ACROSS EAST-
CENTRAL OKLAHOMA EXTENDING INTO FAR NORTHWEST ARKANSAS THIS
AFTERNOON. SMALLER SCALE IMPULSE CURRENTLY MOVING INTO EASTERN
OKLAHOMA WITH ENHANCED CU FIELD. SOUTH OF BOUNDARY ATMOSPHERE HAS
BECOME MODERATELY UNSTABLE ACROSS SOUTHEAST OKLAHOMA AND NORTHWEST
ARKANSAS. MAX HEATING COMBINED WITH EASTWARD MOVING DISTURBANCE
SHOULD BE ENOUGH FOR SCATTERED THUNDERSTORM DEVELOPMENT THIS
AFTERNOON AND EVENING. THE STRONGER STORMS WILL BE CAPABLE OF
DAMAGING WINDS AND VERY HEAVY RAINFALL.

FLASH FLOOD GUIDANCE REMAINS LOW ACROSS MUCH OF EASTERN OKLAHOMA
AND NORTHWEST ARKANSAS FROM PREVIOUS RAINS. STILL SOME UNCERTAINTY
REGARDING MCS EVOLUTION INTO THE OVERNIGHT HOURS...HOWEVER GIVEN THE
HIGH RAINFALL RATES/SLOW STORM MOTIONS EXPECTED WITH ANY
THUNDERSTORM ACTIVITY HAVE DECIDED TO GO AHEAD AND ISSUE A FLASH
FLOOD WATCH FOR PORTIONS OF EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS TONIGHT. THUNDERSTORMS COULD LINGER INTO SATURDAY MORNING
ACROSS NORTHWEST ARKANSAS BEFORE STORMS SLOWLY WEAKEN.

ACTIVE WEATHER PATTERN WILL CONTINUE INTO NEXT WEEK WITH A
CONTINUED CHANCE FOR SHOWERS/THUNDERSTORMS. ANOTHER WEAK FRONTAL
BOUNDARY WILL MOVE INTO THE AREA DURING THE TUE/WED TIME FRAME
WITH A SERIES OF UPPER DISTURBANCES MOVING OUT OF THE CENTRAL
ROCKIES. THIS WILL AGAIN PROVIDE THE CHANCE FOR THUNDERSTORMS WITH
HEAVY RAIN THROUGH MID WEEK...WHICH COULD LEAD TO MORE FLOODING
PROBLEMS. HIGH PRESSURE TRIES TO BUILD INTO THE CENTRAL/SOUTHERN
PLAINS BEHIND FRONT BY LATE WEEK WITH DRIER AND MORE MILD
CONDITIONS.

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

.DAY ONE...THROUGH TONIGHT.

SEVERE THUNDERSTORM.
	RISK...ELEVATED.
	AREA...SOUTHEAST OKLAHOMA...WEST CENTRAL AND NORTHWEST OKLAHOMA .
	ONSET...ONGOING.

FLASH FLOOD.
	RISK...LIMITED.
	AREA...MUCH OF EASTERN OKLAHOMA...WEST CENTRAL AND NORTHWEST
               ARKANSAS.
	ONSET...ONGOING.

HEAVY RAIN.
	RISK...LIMITED.
	AREA...EASTERN OKLAHOMA...WEST CENTRAL AND NORTHWEST ARKANSAS.
	ONSET...ONGOING.

DANGEROUS HEAT.
	RISK...LIMITED.
	AREA...EXTREME SOUTHEAST OKLAHOMA.
	ONSET...ONGOING...BUT DIMINISHING AFTER SUNSET.

DISCUSSION...
SCATTERED THUNDERSTORMS HAVE DEVELOPED IN THE VICINITY OF A NEARLY
STATIONARY BOUNDARY LATE THIS AFTERNOON. AS A RESULT...STORMS
THIS AFTERNOON AND EVENING WILL BE CAPABLE OF DAMAGING WINDS AND
HAIL THAT DEVELOP ALONG AND SOUTH OF INTERSTATE 40...DUE TO HIGH
INSTABILITY IN THIS REGION. THE RISK OF SEVERE WEATHER WILL
CONTINUE PRIMARILY IN TO EARLY EVENING BEFORE DIMINISHING.

A FLASH FLOODING RISK CONTINUES WITH THE STORMS ACROSS THE REGION
THROUGH TONIGHT. HOWEVER...AREAS NEAR THE KANSAS
BORDER...AND ESPECIALLY FAR NORTHWEST ARKANSAS WHERE SOILS REMAIN
SATURATED IN PARTS OF BENTON AND CARROLL COUNTIES. ADDITIONAL
RAINFALL IN THOSE AREAS WILL QUICKLY AGGRAVATE ONGOING FLOODING
IN A MODERATE OR HEAVY DOWNPOUR. A FLASH FLOOD WATCH REMAINS IN
EFFECT FOR PARTS OF FAR NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS
AND HAS BEEN EXPANDED TO INCLUDE MORE OF EASTERN OKLAHOMA...AND
WEST CENTRAL ARKANSAS THROUGH EARLY TOMORROW MORNING.

ANOTHER OVERNIGHT THUNDERSTORM COMPLEX COULD DEVELOP AND MOVE
ACROSS PORTIONS OF EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.
MODERATE TO HEAVY RAINS COULD LEAD TO ADDITIONAL FLASH FLOODING
OVERNIGHT...WITH A LESSER RISK OF STRONG TO DAMAGING WINDS.

AFTERNOON HEAT INDEX VALUES OF 100 TO 105 DEGREES ARE POSSIBLE
ACROSS EXTREME SOUTHEAST OKLAHOMA TODAY...HOWEVER CONDITIONS WILL
IMPROVE SOME LATER THIS EVENING AFTER SUNSET.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
ACTIVATION OF THE REGIONAL SPOTTER NETWORK LIKELY.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY THROUGH MONDAY...THUNDERSTORM POTENTIAL...DANGEROUS HEAT POTENTIAL.
TUESDAY THROUGH THURSDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...
THUNDERSTORM CHANCES WILL CONTINUE OVER THE WEEKEND...AND THROUGH
MUCH OF NEXT WEEK. SEVERAL WEAK COLD FRONTS WILL PUSH SOUTHWARD INTO
THE REGION...AND REMAIN A FOCUS FOR THUNDERSTORMS. ALSO...THE
WEATHER PATTERN THROUGH THE CENTRAL PLAINS WILL SUPPORT REPEATED
THUNDERSTORM DEVELOPMENT...AS HIGH PRESSURE WILL REMAIN LOCATED
ACROSS THE SOUTHWESTERN STATES. A FEW HOT AND HUMID AFTERNOONS ARE
POSSIBLE OVER THE WEEKEND...WITH COOLER WEATHER PREVAILING FOR THE
FIRST PART OF THE NEXT WORK WEEK.
