AREA FORECAST DISCUSSION

552 AM CDT SAT MAR 19 2011

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM.

TSRA HAS BEEN INCREASING THIS MORNING NEAR BVO IN RESPONSE TO LLJ.
CHANCE EXISTS THRU MID TO LATE MORNING OF ADDITIONAL TSRA TO
AFFECT BVO/TUL/RVS...WITH GREATEST CHANCE AT BVO. WILL CARRY
PREVAILING VCTS MENTION AT BVO...WITH TEMPO GROUPS AT TUL/RVS.
OTRW...CIG FORECAST LOOKING MORE OPTIMISTIC THAN PREVIOUSLY...WITH
A RELATIVELY SHORT PERIOD OF MVFR CIGS EXPECTED AT TERMINALS AS
WINDS SHIFT TO A MORE SRLY DIRECTION TODAY.

.PREV DISCUSSION... /ISSUED 405 AM CDT SAT MAR 19 2011/

DISCUSSION...
SURFACE FRONTAL BOUNDARY LIES GENERALLY NEAR THE RED RIVER VALLEY
AND EXTENDS INTO SOUTHERN ARKANSAS. TIME LAPSE OF AREA RADAR VAD
WIND PROFILES SHOW A NOTICEABLE EROSION OF THE FRONTAL DEPTH
OVERNIGHT...AND THIS LENDS SUPPORT TO RECENT MODEL SOLUTIONS OF
ALLOWING THE WARM SECTOR AIRMASS TO REACH FURTHER INTO NE OK
TODAY. THE MORE COMPLEX TERRAIN OF NW ARKANSAS LIKELY LIMITED THE
IMPACT OF COOLER AIRMASS INITIALLY...BUT WILL ALSO SLOW THE RETURN
OF MUCH WARMER TEMPS. PRECIP CHANCES TODAY WILL BE HIGHEST NORTH
OF THE RETREATING WARM FRONT FRONT. LATEST DATA SUGGEST THE
ONGOING LIGHT SHOWERS ACROSS NE OK WILL CONTINUE INTO MID
MORNING...WITH RENEWED DEVELOPMENT NEARER THE SURFACE FRONT LATER
TODAY WHICH WOULD BE ACROSS FAR NORTHERN LOCATIONS OR POSSIBLY
EVEN NORTH OF THE FORECAST AREA. THESE STORMS COULD BECOME STRONG
TO POSSIBLY SEVERE WITH LARGE HAIL THE LIKELY IMPACT. TEMPERATURES
REMAIN MILD OVERNIGHT AS BREEZY SOUTHERLY WINDS ARE MAINTAINED
BENEATH A STRONG LOW LEVEL JET. ISOLATED OVERNIGHT CONVECTION IS
ALSO POSSIBLE NEARER THE LOW LEVEL JET CORE / WARM ADVECTION AXIS.

SEASONABLY WARM TEMPERATURES RETURN AREA WIDE ON SUNDAY WITH STRONG
SOUTHERLY WINDS AND DELAYED MOISTURE RETURN ALLOWING FOR
AGGRESSIVE WILDFIRE BEHAVIOR FOR ALL EASTERN OK / NW AR. BREEZY
CONDITIONS CONTINUE INTO MONDAY WITH A GRADUAL RISE IN DEWPOINTS
MAINTAINING MILD OVERNIGHT LOW TEMPS...WITH CONTINUED WARM DAYS
AHEAD OF THE NEXT COLD FRONT WHICH ARRIVES DURING THE DAY TUESDAY.

PRECIP CHANCES WITH THE TUESDAY/TUESDAY NIGHT FRONT APPEAR RATHER
LOW AS PRE-FRONTAL CAP STRENGTH WILL BE FORMIDABLE AND THE
STRONGER DYNAMICS ARE FOCUSED FURTHER NORTH. FRONTAL FORCING MAY
BE ENOUGH FOR ISOLATED SHOWERS AND STORMS...WITH THE FRONT
SWEEPING THROUGH THE AREA BY WEDNESDAY MORNING.

THE PATTERN ALOFT WILL SUPPORT FAST MOVING WAVES SWEEPING ACROSS
THE SOUTHERN TIER OF STATES FOR THE LATTER HALF OF THE WEEK. ONE
POSSIBLE WAVE MAY INTERACT WITH THE MID WEEK COLD FRONT AND BRING
A CHANCE OF PRECIP LATE THURSDAY INTO FRIDAY...BEFORE ALLOWING A
STRONGER PUSH OF THE COOLER SURFACE HIGH PRESSURE SOUTHWARD. THE
NEXT WAVE LOOKS TO IMPACT THE REGION JUST BEYOND THIS FORECAST
TIMEFRAME.

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

.DAY ONE...TODAY AND TONIGHT.

SEVERE THUNDERSTORM.
	RISK...ELEVATED.
	AREA...NORTH OF INTERSTATE 40.
	ONSET...ONGOING.

FLASH FLOOD.
	RISK...LIMITED.
	AREA...NORTH OF INTERSTATE 44.

	ONSET...ONGOING.

FIRE WEATHER DANGER.
	RISK...LIMITED.
	AREA...WEST OF HIGHWAY 75 IN SOUTHEAST OKLAHOMA.
	ONSET...LATE MORNING.

DISCUSSION...
THE FRONT THAT PASSED THROUGH THE AREA YESTERDAY WILL REMAIN
LARGELY STATIONARY THROUGH MOST OF THE DAY...AND WILL ALSO BEGIN
TO WEAKEN. THUNDERSTORMS WILL CONTINUE TO DEVELOP THIS MORNING TO
THE NORTH OF THE BOUNDARY ACROSS MAINLY NORTHEAST OKLAHOMA AND
NORTHWEST ARKANSAS...AS AN UPPER LEVEL DISTURBANCE MOVES ACROSS
THE REGION. WIDESPREAD SEVERE WEATHER IS NOT ANTICIPATED...BUT
SUFFICIENT INSTABILITY EXISTS FOR AN ISOLATED HAIL PRODUCING SEVERE
STORM. LOCALLY HEAVY RAINFALL WILL ALSO BE POSSIBLE WITH THE
HEAVIER STORMS. THE THUNDERSTORM THREAT WILL DIMINISH DURING THE
LATE AFTERNOON AND INTO THE OVERNIGHT HOURS.

WARMER AIR WILL BEGIN TO RETURN TO PORTIONS OF THE
AREA...ESPECIALLY SOUTHEAST OKLAHOMA. THIS WILL HELP FUEL A
LIMITED FIRE DANGER MAINLY ACROSS LOCATIONS ALONG AND WEST OF THE
HIGHWAY 75 CORRIDOR IN SOUTHEAST OKLAHOMA.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
LOCAL SPOTTER ACTIVATION MAY BE REQUIRED...BUT ACTIVATION OF THE
REGIONAL SPOTTER NETWORK IS NOT ANTICIPATED.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
SUNDAY AND MONDAY...VERY HIGH FIRE WEATHER POTENTIAL...HIGH WIND POTENTIAL.
TUESDAY...THUNDERSTORM POTENTIAL...VERY HIGH FIRE WEATHER POTENTIAL...
          HIGH WIND POTENTIAL.
WEDNESDAY...NO HAZARDS.
THURSDAY...THUNDERSTORM POTENTIAL.
FRIDAY...NO HAZARDS.

EXTENDED DISCUSSION...
WELL ABOVE NORMAL TEMPERATURES WILL AGAIN BE SEEN ACROSS ALL OF
EASTERN OKLAHOMA AND NORTHWEST ARKANSAS SUNDAY THROUGH TUESDAY.
SOUTH WINDS AT SUSTAINED SPEEDS OF 15 TO 25 MPH...AND GUSTS TO 35
MPH...WILL DEVELOP ON SUNDAY...AND WILL FUEL VERY HIGH FIRE DANGER
DURING THE AFTERNOON. MONDAY AND TUESDAY AFTERNOONS WILL ALSO
FEATURE SIMILAR WIND SPEEDS AND GUSTS...CONTINUING THE FIRE
DANGER INTO THESE DAYS.

A STRONG UPPER LEVEL DISTURBANCE WILL MOVE INTO THE CENTRAL PLAINS
DURING THE DAY TUESDAY...CAUSING SURFACE LOW PRESSURE TO DEVELOP.
THE ATTENDANT DRYLINE WILL MOVE THROUGH THE AREA TUESDAY
NIGHT...AND WILL RESULT IN A SMALL CHANCE OF SEVERE THUNDERSTORMS.
ANY SOUTHWARD SHIFT IN THE FORECAST TRACK OF THE SURFACE LOW WILL
INCREASE THE CHANCE OF SEVERE WEATHER IN THE AREA.

ANOTHER SMALL CHANCE OF THUNDERSTORMS EXISTS THURSDAY NIGHT AS A
FAST MOVING DISTURBANCE MOVES ACROSS THE AREA.
