Area forecast discussion, Aug 8, 6:25 PM CDT, 1 hour 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
625 PM CDT WED AUG 8 2012

...UPDATE...

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM.
SCATTERED STRONG TO SEVERE STORMS ALONG WITH MULTIPLE
OUTFLOW BOUNDARIES WILL CONTINUE TO RESULT IN ERRATIC
WIND DIRECTIONS AND SPEEDS FOR THE NEXT SEVERAL HOURS.
THUNDERSTORMS NEAR THE KMLC TAF SITE WILL GRADUALLY
DIMINISH AFTER 02Z...WITH ADDITIONAL STORMS POTENTIALLY
IMPACTING THE KFYV/KXNA SITES FROM THE NORTH BY 01-02Z.
EXPECT PERIODIC MVFR/IFR CONDITIONS IN AND NEAR STORMS.
MOST OF THE ACTIVITY SHOULD WEAKEN AFTER 06Z. A COLD
FRONT WILL MOVE THROUGH THE REGION THURSDAY MORNING
AND COULD RESULT IN A FEW LATE AFTERNOON STORMS FOR
KMLC/KFSM.

&&

.PREV DISCUSSION... /ISSUED 343 PM CDT WED AUG 8 2012/

DISCUSSION...
ONGOING CONVECTION WILL MAINTAIN A RISK OF DAMAGING DOWNBURST
WINDS ACROSS SE OK AND WESTERN AR INTO SUNSET...WITH ATTENTION
THEN TURNING TO EXPANDING CONVECTION ACROSS THE CENTRAL PLAINS.
THIS CONVECTION WILL BE FORCED BY A RESPECTABLE MID LEVEL WAVE FOR
EARLY AUGUST...AND LIKELY DEVELOP SOUTH AND EASTWARD AFTER SUNSET.
GIVEN THE DEEPLY MIXED AND NOT-YET OVERTURNED BOUNDARY LAYER IN
PLACE ACROSS NE OK...THE CONVECTION WILL HAVE A GOOD CHANCE OF
DEVELOPING INTO THE REGION. THE SOUTHWARD EXTENT SHOULD BE LIMITED
BY THE ONGOING CONVECTION AND ITS EFFECTS ON STABILIZING THE
BOUNDARY LAYER. THIS SCENARIO IS LARGELY SUPPORTED BY THE 18Z NAM
AND HRRR OUTPUT.

THE COLD FRONT ASSOCIATED WITH THE PASSING WAVE WILL MOVE INTO NE
OK BY SUNRISE THURSDAY...AND THROUGH MUCH OF THE FORECAST AREA BY
SUNSET THURSDAY. STORM CHANCES WILL RESIDE ALONG AND SOUTH OF THE
BOUNDARY PRIMARILY DURING THE AFTERNOON HOURS ON THURSDAY.
NOTICEABLY DRIER AND COOLER AIR WILL FOLLOW THE FRONT AND BRING
TEMPS NEAR NORMAL FRIDAY AND SATURDAY. RAINFALL FOOTPRINTS...OR
LACK THEREOF...MAY LARGELY AFFECT THE DEGREE OF COOLING GIVEN THE
VERY WARM GROUND TEMPS AND LACK OF CLOUD COVER BEHIND THE FRONT.

UPPER RIDGING WILL ATTEMPT TO EXPAND BACK EASTWARD OVER THE
WEEKEND...THOUGH IT LOOKS TO BE SUPPRESSED FURTHER SOUTH AND NOT
HAVE AS STRONG AS INFLUENCE AS RECENTLY. SOUTHERN PERIPHERY OF A
PASSING WAVE MAY SUPPORT PRECIP LATE SUNDAY INTO
MONDAY...OTHERWISE NO SIGNIFICANT PRECIP CHANCES ARE NOTED UNTIL
POSSIBLY JUST BEYOND THIS FORECAST TIME FRAME.

AREA...EASTERN OKLAHOMA AND PORTIONS OF NORTHWEST ARKANSAS.
ONSET...ONGOING.

DISCUSSION...
ONGOING THUNDERSTORMS ACROSS THE AREA THIS AFTERNOON HAVE BEEN
STRONG TO SEVERE AT TIMES... WITH SOME PRODUCING DAMAGING WINDS.
ADDITIONAL DEVELOPMENT WILL BE POSSIBLE INTO TONIGHT. A STRONG
UPPER WAVE WILL TRAVERSE THE EASTERN PORTION OF THE AREA AFTER
SUNSET WHICH WILL PROVIDE SUPPORT FOR ADDITIONAL DEVELOPMENT. THE
STRONGER STORMS WILL ALSO BE CAPABLE OF PRODUCING HEAVY
RAINFALL... WITH RATES UP TO 2 INCHES PER HOUR. THIS WILL CREATE A
DANGER FOR LOCALIZED FLASH FLOODING.

WHERE IT HAS NOT RAINED... DANGEROUS HEAT WILL CONTINUE. DANGEROUS
FIRE WEATHER CONDITIONS WILL ALSO CONTINUE IN THESE AREAS AS WELL.
THERE ARE ALREADY SEVERAL LARGE WILDFIRES ONGOING. ANY STORMS
CLOSE TO THESE MAY ACTUALLY HAMPER FIRE FIGHTING EFFORTS WITH
STRONG AND CHAOTIC OUTFLOW WINDS.

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

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
THURSDAY...THUNDERSTORM POTENTIAL...VERY HIGH FIRE WEATHER POTENTIAL...DANGEROUS HEAT POTENTIAL.
FRIDAY...VERY HIGH FIRE WEATHER POTENTIAL.
SATURDAY...NO HAZARDS.
SUNDAY...THUNDERSTORM POTENTIAL.
MONDAY...THUNDERSTORM POTENTIAL.
TUESDAY...VERY HIGH FIRE WEATHER POTENTIAL.

EXTENDED DISCUSSION...
NORTHWEST FLOW ALOFT WILL MAINTAIN A CHANCE FOR THUNDERSTORMS
THROUGH THE DAY THURSDAY... AS A COLD FRONT MOVES THROUGH THE
AREA. HIGH PRESSURE WILL BUILD BEHIND THE FRONT THURSDAY NIGHT AND
BRING DRY WEATHER ONCE AGAIN. THE DRIER CONDITIONS AND INCREASED
WINDS ASSOCIATED WITH THE FRONTAL PASSAGE WILL LEAD TO AN ELEVATED
THREAT OF RAPID FIRE SPREAD FOR THURSDAY AND FRIDAY. ANOTHER FRONT
WILL TRY TO MOVE INTO THE AREA ON SUNDAY... THEN STALL OUT. THAT
WILL PROVIDE A CHANCE OF THUNDERSTORMS SUNDAY THROUGH TUESDAY.
