What forecasters said that day

The local office's own words before this severe thunderstorm warning 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 severe thunderstorm warning went out at Jul 23, 4:18 PM CDT, 1 hour 2 minutes earlier.

Area forecast discussion, Jul 23, 4:18 PM CDT, 1 hour 2 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
418 PM CDT WED JUL 23 2014

.DISCUSSION...
CONVECTIVE COMPLEX CONTINUES TO MOVE SOUTH AND SOUTHWEST AND WILL
EXIT OUR FORECAST AREA BY AROUND 00Z. NUMEROUS REPORTS OF DAMAGING
WINDS HAVE BEEN RECEIVED WITH THESE STORMS. WILL CANCEL THE HEAT
ADVISORY A FEW HOURS EARLY AS STORM OUTFLOW HAS COOLED THE AIRMASS.

THE HEAT WILL BEGIN TO BUILD BACK THURSDAY AND ESPECIALLY
FRIDAY AND HEAT HEADLINES WILL ALMOST CERTAINLY BE REQUIRED AGAIN
BY FRIDAY INTO THE WEEKEND. TRIPLE DIGIT HEAT IS LIKELY IN PARTS
OF NORTHEAST OKLAHOMA FRIDAY AND WILL EXPAND SOMEWHAT SATURDAY.
THE NAM12 IS ESPECIALLY HOT AND IF IT VERIFIES...EVEN THESE
FORECAST NUMBERS WILL BE SEVERAL DEGREES TOO COOL.

RELIEF IS ON THE WAY BY EARLY NEXT WEEK AS AN UPPER TROF DEVELOPS
OVER THE GREAT LAKES REGION AND DRIVES A COLD FRONT SOUTH ACROSS
OUR AREA. WILL CARRY LOW POPS SUNDAY NIGHT AND MONDAY AS THIS
FRONT MOVES THROUGH.

THE UPPER TROF WILL REMAIN IN PLACE MOST IF NOT ALL OF NEXT WEEK
SO TEMPERATURES WILL REMAIN WELL BELOW NORMAL FOR AN EXTENDED
PERIOD OF TIME. UPPER DISTURBANCES MOVING DOWN THE WESTERN SIDE OF
THE TROF WILL ALSO RESULT IN PERIODIC RAIN CHANCES NEXT WEEK.

STAYED CLOSE TO GUIDANCE TEMPERATURES THE NEXT COUPLE DAYS.
