The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Norman, OK (KOUN), launched 12:00Z, 10.4 hours before the alert went out and 176 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jul 26, 2:59 PM CDT, 2 hours 24 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
259 PM CDT MON JUL 26 2010

.DISCUSSION...
CONVECTION...AND EVEN CUMULUS...HAS BEEN SLOWER TO APPEAR TODAY.
STILL BELIEVE THAT SCATTERED SHOWERS AND STORMS WILL BECOME A BIT
MORE NUMEROUS OVER THE NEXT FEW HOURS...WITH THE ACTIVITY
CONTINUING INTO THE EVENING BEFORE DISSIPATING. A MOIST AND
RELATIVELY UNCAPPED AIRMASS WILL REMAIN OVER THE AREA FOR THE NEXT
FEW DAYS CONTINUING THE POTENTIAL FOR DIURNAL CONVECTION. AS TIME
GOES ON...THE CONVECTION WILL TEND TO FOCUS OVER THE TERRAIN
FAVORED AREAS.

THE UPPER RIDGE TO OUR EAST WILL RETROGRADE BACK OVER THE AREA BY
THIS WEEKEND INTO EARLY NEXT WEEK WHICH WILL BRING AN END TO THE
CONVECTION AND AN INCREASE IN MAXIMUM TEMPERATURES. MUCH OF THE
AREA WILL LIKELY SEE TRIPLE DIGIT HEAT BY LATE IN THE WEEKEND INTO
EARLY NEXT WEEK.

THE NEW ECMWF CONTINUES TO RETROGRADE THE RIDGE EARLY NEXT WEEK
WHICH MAY RESULT IN A COLD FRONT MAKING IT INTO THE AREA JUST
BEYOND THE RANGE OF THIS FORECAST. WE WILL HAVE TO WAIT AND SEE ON
THIS.

HAVE NOT STRAYED FAR FROM GUIDANCE TEMPERATURES THE NEXT COUPLE
DAYS.

DISCUSSION...
SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS
AFTERNOON AS AN UPPER LEVEL LOW PRESSURE SYSTEM WOBBLES ACROSS
NORTH CENTRAL TEXAS. INSTABILITY AND UPPER WIND FIELDS ARE NOT
OVERLY IMPRESSIVE...BUT A FEW STORMS MAY PRODUCE WIND GUSTS TO
AROUND 50 MILES AN HOUR...ESPECIALLY ACROSS SOUTHEAST OKLAHOMA AND
WEST-CENTRAL ARKANSAS. LOCALLY HEAVY RAIN WILL ALSO BE A CONCERN
DUE TO THE SLOW MOVEMENT OF THE STORMS.  MOST OF THE THUNDERSTORM
ACTIVITY SHOULD DIMINISH DURING THE LATE EVENING HOURS WITH THE
LOSS OF HEATING.

MUCH OF EASTERN OKLAHOMA AND WEST CENTRAL ARKANSAS FOR THE REMAINDER

EXTENDED DISCUSSION...
A TROPICAL LIKE AIRMASS WILL REMAIN ACROSS THE REGION THIS WEEK...
SUPPORTING PERIODS OF MAINLY DIURNAL SHOWERS AND THUNDERSTORMS. AN
UPPER RIDGE WILL BUILD OVER THE SOUTHERN PLAINS TOWARDS THE END OF
THE WORK WEEK LIMITING THE CHANCES OF SHOWERS AND THUNDERSTORMS BY THE
WEEKEND.

THE HEAT WILL BECOME MORE OF A CONCERN OVER THE WEEKEND WITH TRIPLE
DIGIT TEMPERATURES POSSIBLE ACROSS PORTIONS OF EASTERN OKLAHOMA
AND WEST-CENTRAL ARKANSAS.
