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, 11.7 hours before the alert went out and 227 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 19, 2:36 PM CDT, 4 hours 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
236 PM CDT TUE JUL 19 2005

.DISCUSSION...
MAIN FORECAST PROBLEMS IN THE SHORT TERM INVOLVE PRECIP CHANCES
THIS EVENING AND AGAIN WED AFTERNOON...AND RISING TEMPS THROUGH
THE END OF THE WEEK. THE AREA WILL REMAIN UNDER THE WANING
INFLUENCE OF SHEAR AXIS THROUGH WED. SCATTERED CONVECTION HAS
DEVELOPED IN ASSOCIATION WITH THIS FEATURE THIS AFTERNOON...AND HAS
BEEN ENHANCED OVER FAR NE OKLAHOMA BY OUTFLOW BOUNDARY FROM
MORNING STORM COMPLEX OVER SE KANSAS. OUTSIDE CHANCE OF A NEAR
SEVERE DOWNBURST WIND GUST BEFORE ACTIVITY DIES AFTER SUNSET.

SHEAR AXIS INFLUENCE WILL DIMINISH WITH TIME AS UPPER RIDGE
BEGINS TO TAKE OVER. PRECIP CHANCES CONFINED TO FAR EASTERN
SECTIONS WED AFTERNOON. TEMPS WILL BE ON THE RISE GRADUALLY
THROUGH THE REST OF THE WEEK AS HEIGHTS BUILD...WITH PRECIP
CHANCES BECOMING NEGLIGIBLE FROM THU ON. POSSIBILITY OF A WEAK
EASTERLY WAVE AFFECTING FAR SE OKLAHOMA BY THE WEEKEND...BUT WILL
NOT INCLUDE ANY PRECIP IN THE FORECAST.

AS RIDGE TAKES HOLD EXPECT TEMPS TO CLIMB AND SHOULD SEE HOTTEST
TEMPS OF THE SEASON BY WEEKS END. MAV GUIDANCE HAS BEEN WARMING US
UP TOO FAST OVER THE LAST SEVERAL DAYS AND WILL STICK WITH TREND
OF UNDERCUTTING MAV HIGH TEMPS FOR NOW. WILL BE INTERESTING TO SEE
IF THIS TREND CHANGES LATER IN THE WEEK AS THINGS DRY OUT.
