The local office's own words before the first event, 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 the first event at Jun 16, 3:06 AM CST, 2 hours 22 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OK 406 AM CDT TUE JUN 16 2009 .DISCUSSION... HOT AND MAINLY DRY WEATHER WILL BE THE RULE THROUGHOUT THE SEVEN DAY FORECAST PERIOD. WARM FRONT HAS LIFTED NORTH OF THE AREA WHICH HAS KEPT THE MAIN FOCUS FOR CONVECTION TO THE NORTH AS WELL. WE ARE STARTING TO SEE SOME DEVELOPMENT ON THE SOUTH END OF THE COMPLEX IN SOUTHEAST KANSAS SO WILL GO WITH LOW POPS THIS MORNING FOR PARTS OF FAR NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS. ANY REDEVELOPMENT THIS AFTERNOON AND EVENING SHOULD REMAIN TO OUR NORTH AND NORTHEAST. A WEAK COLD FRONT IS STILL SLATED TO MOVE ACROSS THE AREA FRIDAY AND FRIDAY NIGHT. SCATTERED SHOWERS AND THUNDERSTORMS WILL LIKELY ACCOMPANY THIS FRONT AS IT PROGRESSES ACROSS THE AREA. ONLY VERY MINOR COOLING IS EXPECTED FOLLOWING THE FRONTAL PASSAGE. THE UPPER RIDGE IS STILL FORECAST TO RETROGRADE TO THE ROCKIES BY NEXT WEEK WHICH IS CLIMATOLOGICALLY A VERY HOT PATTERN FOR US. HIGHS IN THE MID TO UPPER 90S WITH LOWS IN THE MID TO UPPER 70S WILL BE COMMON BY THE END OF THE FORECAST PERIOD AND FOR SEVERAL DAYS BEYOND THE WAY IT APPEARS AT THIS TIME. CANNOT RULE OUT 100 DEGREES IN SOME PLACES SOMETIME NEXT WEEK BUT SINCE THE MOST RECENT 100 DAY IN JUNE IN TULSA WAS IN 1994...IT IS DIFFICULT TO FORECAST READINGS THAT WARM THIS FAR EAST THIS EARLY IN THE SEASON. DID NOT STRAY FAR FROM GUIDANCE TEMPERATURES THE NEXT COUPLE DAYS. && .PRELIMINARY POINT TEMPS/POPS...
