What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tulsa, OK wrote its last area forecast discussion before this special weather statement went out at Aug 9, 3:51 AM CDT, 15 minutes earlier.

Area forecast discussion, Aug 9, 3:51 AM CDT, 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
351 AM CDT TUE AUG 9 2011

.DISCUSSION...
ONGOING THUNDERSTORMS ARE EXPECTED TO BE EAST AND SOUTH OF THE
FORECAST AREA SOON AFTER SUNRISE...AND WITH CLEARING SKIES
TEMPERATURES WILL WARM QUICKLY. EXPECTED AFTERNOON HEAT INDEX
FORECASTS ALIGN WELL WITH CURRENT EXCESSIVE HEAT WARNING AND WILL
CONTINUE THE SAME COUNTY CONFIGURATION...AND REMOVE THE HEAT WATCH
FOR FAR NORTHERN LOCATIONS. INCREASING UPSLOPE FLOW NORTH WILL
DEVELOP A STORM COMPLEX TO OUR NORTHWEST TONIGHT...WITH THIS
COMPLEX EXPANDING SOUTHEASTWARD OVERNIGHT AND CONTINUING INTO
WEDNESDAY. THE EXACT PLACEMENT AND TRACK OF THESE SYSTEMS IS
ALWAYS A CHALLENGE...WITH THE CURRENT PLAN BEING THAT NORTHERN
AREAS STAND A GOOD SHOT AT RAIN WITH THE RESULTANT CLOUD COVER AND
COOL OUTFLOW HOLDING TEMPS DOWN MARKEDLY ON WEDNESDAY. THE COOLING
POTENTIAL DROPS OFF CONSIDERABLY FURTHER SOUTH...AND TO THE POINT
WHERE 105 HEAT INDEX VALUES REMAIN LIKELY THUS AN EXCESSIVE HEAT
WATCH HAS BEEN POSTED FOR SOUTHERN LOCATIONS. THIS SCENARIO
CONTAINS CONSIDERABLE UNCERTAINTY HINGING ON THE OVERNIGHT STORM
COMPLEX.

THE OUTLFOW/COLD FRONTAL BOUNDARY WILL REMAIN IN THE AREA THURSDAY
AND ATTEMPT TO LIFT NORTHWARD FRIDAY...ALL THE WHILE REMAINING A
FOCUS FOR ADDITIONAL STORM CHANCES. TEMPERATURES WILL ALSO BE HELD
NEARER SEASONAL NORMALS THOUGH FAR SOUTHEAST OKLAHOMA MAY STRUGGLE
TO COOL OFF TOO MUCH. THE NEXT COLD FRONT ARRIVES SATURDAY WITH A
GOOD SHOT AT PUSHING THROUGH THE ENTIRE FORECAST AREA AND
PROVIDING A FEW DAYS OF COOLER TEMPS THROUGH THE WEEKEND. AS THIS
FRONTAL BOUNDARY RETURNS NORTHWARD...THE UPPER RIDGE WILL AGAIN BE
AMPLIFYING ACROSS THE CENTRAL U.S. AND THE RETURN TO ABOVE NORMAL
TEMPERATURES IS LIKELY.

...DANGEROUS WILDFIRE SITUATION THROUGH THE EVENING HOURS...
...RISK OF SEVERE STORMS THIS EVENING INTO THE OVERNIGHT HOURS...

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...NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS.
ONSET...THIS EVENING.

DANGEROUS HEAT.
RISK...SIGNIFICANT.
AREA...NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS.
ONSET...ONGOING.

SIGNIFICANT WINDS.
RISK...LIMITED.
AREA...EASTERN OKLAHOMA.
ONSET...ONGOING.

FIRE WEATHER DANGER.
RISK...SIGNIFICANT.
AREA...EASTERN OKLAHOMA NORTHWEST ARKANSAS.
ONSET...ONGOING.

DISCUSSION...
ONGOING FIRE SITUATION MAY BECOME CRITICAL THIS EVENING AS DEVELOPING
STRONG TO SEVERE THUNDERSTORMS PRODUCE OUTFLOW BOUNDARIES WITH WIND
GUSTS WELL IN EXCESS OF 40 MILES AN HOUR. RELATIVE HUMIDITY VALUES OF
20 TO 30 PERCENT AND ERRATIC WIND DIRECTIONS FROM THUNDERSTORMS MAY
MAKE FIRE SUPPRESSION NEARLY IMPOSSIBLE.

THE ATMOSPHERE IS WELL PRIMED BY EXCESSIVE HEAT AND DRY LOWER LEVELS
TO PRODUCE LOCAL DOWNBURST WINDS OF 70 MILES AN HOUR. HAIL WILL BE
A SECONDARY SEVERE THREAT.

A WEST TO EAST BOUNDARY FROM AROUND PONCA CITY TO TULSA TO AROUND
FAYETTEVILLE WILL LIFT SLOWLY NORTH THEN STALL AS AN IMPULSE MOVING
ACROSS THE REGION IGNITES THUNDERSTORMS. THOSE STORMS WILL BE MOST
NUMEROUS NEAR AND NORTH OF THE BOUNDARY OVER NORTHEAST OKLAHOMA AND
NORTHWEST ARKANSAS.

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

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

EXTENDED DISCUSSION...
DANGEROUSLY HOT AND HUMID CONDITIONS WILL PERSIST THROUGH MUCH OF
THE WEEK. THE FRONTAL BOUNDARY WILL REMAIN IN THE AREA WITH THE
POTENTIAL FOR MAINLY AFTERNOON THUNDERSTORMS. THERE COULD BE AN
ENHANCED SEVERE THREAT ON WEDNESDAY AS MODERATE INSTABILITY COMBINES
WITH STRONG WIND FIELDS ALOFT. THE STRONGER STORMS WOULD LIKELY
POSE A THREAT OF DAMAGING DOWNBURST WINDS. IN ADDITION...FIRE
WEATHER CONCERNS WILL REMAIN HIGH AS GENERALLY HOT AND DRY
CONDITIONS CONTINUE.
