FIRE WARNING
OKLAHOMA DEPARTMENT OF EMERGENCY MANAGEMENT
RELAYED BY NATIONAL WEATHER SERVICE TULSA OK
639 PM CDT SAT AUG 4 2012
THE FOLLOWING MESSAGE IS TRANSMITTED AT THE REQUEST OF THE
OKLAHOMA DEPARTMENT OF EMERGENCY MANAGEMENT.
EVACUATIONS ARE NOW BEING ORDER FOR ALL OF THE COMMUNITY OF
MANNFORD OKLAHOMA AND SURROUNDING AREAS.
A WILDFIRE HAS CONTINUED TO SPREAD UNCONTROLLED TO THE NORTHEAST
AND THE LEADING EDGE OF THE FIRE WAS ON THE VERGE OF ENTERING MANNFORD.
PEOPLE SHOULD EVACUATE TO THE UNITED METHODIST CHURCH IN
SAND SPRINGS AT 101 WEST 38TH STREET.
SPECIAL NOTE... A FRONT AND THUNDERSTORM OUTFLOWS ARE MOVING
TOWARD THE MANNFORD AREA. WIND SHIFTS TO THE WEST AND NORTHWEST
ARE EXPECTED TO OCCUR BETWEEN 830 PM AND 10 PM. STRONG GUSTS WILL
OCCUR WITH ANY THUNDERSTORMS THAT AFFECT THE AREA. WINDS WILL GUST
INTO THE 20S BRIEFLY WITH THE FRONT BEFORE EASING AND BECOMING
NORTHERLY. THESE WINDS WILL RESULT IN ERRATIC FIRE BEHAVIOR AND
TURN IN THE FIRES MOTION TO THE SOUTHEAST AND THEN SOUTH.
With the record breaking temperatures down there, the fire risk is very high and there is a fire warning in effect for the county mentioned above which is beside the county that holds the city of Tulsa. Its weird to see out of control fires there, I don't remember hearing about them in the plains but I think OK had them in 2011. You can see smoke on satellite imagery too.

VALID 041700Z - 051200Z
...CRITICAL FIRE WEATHER AREA FOR NERN-CNTRL-SWRN OK / PARTS OF THE
TX LOW ROLLING PLAINS...
...CRITICAL FIRE WEATHER AREA FOR W-CNTRL NV / SIERRA NEVADA /
PORTIONS OF NRN CA...
...NERN-CNTRL-SWRN OK / PARTS OF THE TX LOW ROLLING PLAINS...
THE ONGOING FORECAST IS ON TRACK. AS SUCH...NO MAJOR CHANGES HAVE
BEEN MADE TO THE CRITICAL AREA DELINEATION OR ACCOMPANYING FORECAST
CONDITIONS PER MORNING OBSERVATIONS AND THE LATEST SHORT-TERM MODEL
GUIDANCE.
IT IS NOTED THAT HIGH-BASED THUNDERSTORMS MAY DEVELOP ON AN ISOLATED
BASIS THIS AFTERNOON IN ASSOCIATION WITH THE FRONT. GIVEN THE
ANTICIPATED FRONTAL POSITION THIS AFTERNOON...AND PER CONSENSUS
AMONGST CONVECTION-ALLOWING MODEL GUIDANCE...THE GREATEST CHANCE FOR
ISOLATED THUNDERSTORMS WILL OCCUR ALONG AND NORTH OF A LINE LYING
FROM COLLINGSWORTH COUNTY TX TO OKLAHOMA COUNTY OK TO ADAIR COUNTY
OK. FORECAST SOUNDINGS INDICATE DEEP INVERTED-VEE THERMODYNAMIC
PROFILES ASSOCIATED WITH LARGE SFC TEMPERATURE-DEWPOINT
SPREADS...WHICH WILL SUPPORT STRONG/ERRATIC OUTFLOW WINDS WITH THE
STORMS. ALONG WITH THE POTENTIAL FOR LIGHTNING-INDUCED IGNITIONS --
ESPECIALLY OVER THE PERIPHERAL AREAS OF RAIN CORES -- THE STRONG
OUTFLOW WINDS MAY CONTRIBUTE TO THE SPREAD OF ANY FIRES.
...W-CNTRL NV / SIERRA NEVADA / PORTIONS OF NRN CA...
NO CHANGES HAVE BEEN MADE TO THE ONGOING FORECAST.
..COHEN.. 08/04/2012
.PREV DISCUSSION... /ISSUED 0242 AM CDT SAT AUG 04 2012/
...SYNOPSIS...
EARLY MORNING SATELLITE IMAGERY SHOWS A PERSISTENT MID-UPPER LEVEL
ANTICYCLONE LOCATED ACROSS THE S-CNTRL STATES. THIS FEATURE WILL
REMAIN NEARLY STATIONARY AS A VIGOROUS UPPER TROUGH MOVES ACROSS THE
UPPER MIDWEST. IN THE LOW LEVELS...A COLD FRONT MOVING SWD OVER THE
CNTRL PLAINS WILL OVERTAKE A TSTM GENERATED OUTFLOW BOUNDARY
--ORIENTED FROM THE TX PANHANDLE INTO SERN KS-- AND PUSH SWD THRU
MUCH OF OK BY DAYBREAK SUNDAY. CRITICAL FIRE WEATHER CONDITIONS ARE
FORECAST OVER A LARGE PORTION OF OK AND A PART OF NWRN TX. FARTHER
W...AN UPPER TROUGH SITUATED OFF THE CA COAST WILL SLOWLY MIGRATE
NWD ALONG THE CNTRL-NRN CA COAST. MONSOONAL MOISTURE WILL ADVECT
NWWD FROM THE DESERT SW AND INTERACT WITH THE APPROACHING UPPER
TROUGH...LEADING TO A CRITICAL DRY TSTM RISK OVER PORTIONS OF WRN
NV/SIERRA NEVADA/NRN CA.
...NERN-CNTRL-SWRN OK / PARTS OF THE TX LOW ROLLING PLAINS...
VERY HOT RECORD-BREAKING TEMPS ARE EXPECTED ACROSS THIS AREA AGAIN
TO THE S OF A FRIDAY NIGHT TSTM GENERATED BOUNDARY DELINEATING
HISTORICALLY HIGH TEMPS VS. COOLER AND LESS FIRE RECEPTIVE
CONDITIONS TO ITS N. WRF-BASED MODEL GUIDANCE SHOWS SUSTAINED SWLY
WINDS APPROACHING 20 MPH /GUSTS 25-30 MPH/...SUPPORTED BY AVERAGE
SPEEDS IN SURFACE-3000 FT AVERAGE FLOW. RH IN THE 10-20 PERCENT
RANGE IS EXPECTED AS TEMPS SOAR INTO THE 105-115 RANGE. OF
PARTICULAR CONCERN ARE MODEL SOUNDING PROFILES DEPICTING NOT ONLY
VERY STEEP LOW LEVEL LAPSE RATES...BUT MODERATE POTENTIAL CONVECTIVE
INSTABILITY. THIS WILL ACT TO PROMOTE EXTREME FIRE BEHAVIOR WITH
ANY PLUME DOMINATED FIRES...GIVEN THE PRECONDITIONING PERIOD OF
HISTORIC HEAT AND EXTREME DROUGHT. A WIND SHIFT WILL ACCOMPANY THE
SWD MOVING COLD FRONT AS WINDS VEER FROM SWLY TO NLY AND TIMED NEAR
THE I-44 CORRIDOR AROUND 03-05Z.
...W-CNTRL NV / SIERRA NEVADA / PORTIONS OF NRN CA...
MODELS ARE IN GOOD AGREEMENT REGARDING THE POTENTIAL FOR SCATTERED
DRY TSTMS AND SPREADING FROM S TO N. THE 00Z REV RAOB SHOWED THE NW
EXTENSION OF MID-LEVEL MONSOONAL MOISTURE AND THIS MOISTURE WILL
CONTINUE TO MOVE INTO THE REGION WITH TIME. CONCURRENTLY...AN UPPER
DISTURBANCE WITH A LOBE OF ASCENT WILL PIVOT ACROSS THE REGION
WITHIN A VERY STEEP LAPSE RATE ENVIRONMENT. THE GREATEST
CONCENTRATION FOR TSTM ACTIVITY WILL BE NEAR AND S OF THE I-80
VICINITY DURING THE 20-06Z PERIOD AND LATER ACROSS NRN CA DURING THE
03-12Z PERIOD.

Some pics and today's events. Over 120 buildings and homes destroyed and a fire that devastated the town of Luther might have been deliberately set.
