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, 10.2 hours before the alert went out and 169 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
NATIONAL WEATHER SERVICE TULSA OKLAHOMA
312 AM CDT SAT JUL 3 2004

COMPLEX OF STORMS ONCE AGAIN ROLLING TO THE SOUTH ACROSS THE AREA
THIS MORNING.  COMPLEX EXPECTED TO WEAKEN OR MOVE OUT OF THE AREA BY
AROUND MIDDAY.  A FEW MARGINALLY SEVERE STORMS THIS MORNING...BUT
THE MAIN CONCERN IS HEAVY RAIN.  WILL CONTINUE FLASH FLOOD WATCH
THIS MORNING IN COUNTIES WHERE BLANKET WARNING WAS ISSUED EARLIER
DURING THE NIGHT.

MAIN UPPER LOW EVIDENT IN SATL LOOP THIS MORNING OVER NORTHERN MO.
SYSTEM WILL CONTINUE LIFTING TOWARD THE GREAT LAKES REGION TODAY
WHICH SHOULD BRING SOME QUIETER WEATHER TO THE AREA FOR A DAY OR
TWO.  STILL SOME DISAGREEMENT AMONG THE MODELS CONCERNING IMPULSES
THAT TRACK THROUGH THE PLAINS OVER THE NEXT 48 HOURS.  THINKING IS
THAT ANY ADDITONAL COMPLEXES THE NEXT FEW NIGHTS WILL REMAIN
GENERALLY TO THE NORTH OF THE AREA WITH THE POTENTIAL TO BRUSH
NORTHERN OR NORTHEASTERN AREAS.

MODELS DO AGREE ON BRINGING NEXT FRONTAL SYSTEM DOWN INTO THE AREA
DURING THE TUESDAY TIMEFRAME AND HANGING THE SYSTEM OVER THE AREA
INTO WEDNESDAY/WEDNESDAY NIGHT. WILL INCREASE POPS AGAIN THROUGH
THAT PERIOD.
