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 00:00Z, 6.8 hours before the alert went out and 157 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.

EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OKLAHOMA
853 PM CDT SAT AUG 2 2003

NOT MUCH GOING ON.  BOUNDARY WOULD APPEAR TO BE NEAR THE RED RIVER
BUT THERE IS NOT ANY ACTIVITY ALONG IT YET.  HAVE MY DOUBTS AS TO
WHETHER THERE EVER WILL BE...AT LEAST TONIGHT.  THE 18Z MESOETA DOES
NOT DEVELOP THE QPF IN THE SOUTH THAT THE 12Z RUN DID.  INSTEAD IT
CHOOSES TO HOLD OFF THE RAIN TIL TOMORROW AFTERNOON.  DO NOT THINK
IT WOULD BE WISE TO DROP POPS ALTOGETHER TONIGHT AND REALLY DO NOT
THINK CAN LIMIT THE POPS TO ANY ONE AREA LOOKING AT THE ACCAS OUT
THE WINDOW.  THUS...HAVE DECIDED TO BROADBRUSH 20 POPS EVERYWHERE
TONIGHT.  WITH ONLY A FEW CLOUDS AROUND HAVE ADJUSTED THE SKY GRIDS
SO IT WILL MAKE THE FORECAST SAY PARTLY CLOUDY EVEN IN THE SOUTHEAST.
UPDATE WILL BE OUT SHORTLY.

.TSA...
AR...NONE.
OK...NONE.
