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.

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 Oct 29, 9:08 AM CDT, 6 minutes earlier.

Area forecast discussion, Oct 29, 9:08 AM CDT, 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
908 AM CDT THU OCT 29 2009

...MESOSCALE UPDATE...

.DISCUSSION...
12Z KSGF/KFWD SOUNDINGS SAMPLED A CONSIDERABLE CAPPING INVERSION
IN PLACE EVEN WHEN MODIFIED FOR CURRENT OBSERVATIONS. THE ONGOING
LINE OF CONVECTION IS LIKELY ROOTED ABOVE THIS INVERSION WITH
MESONET WINDS ALSO SUGGESTING LIMITED INFLUENCE ON A BROAD SCALE
FROM THE PASSAGE OF CONVECTIVE LINE. THAT SAID...EARLIER MEASUREMENT
OF 62KT WINDS AT KSWO INDICATE POTENTIAL FOR ISOLATED AREAS OF
SEVERE WINDS CAPABLE FROM THE STRONGEST BOWING SEGMENTS. LOW LEVEL
SHEAR REMAINS VERY STRONG IN ADVANCE OF THE CONVECTIVE LINE AND
FURTHER SUPPORTS POTENTIAL FOR SEVERE WIND GUSTS. THE EVOLUTION OF
THE SOUTHERN EXTENT OF THE CONVECTIVE LINE CONTINUES REMAINS THE
POSSIBLE AREA FOR MORE WIDESPREAD SEVERE WEATHER POTENTIAL. LATEST
ANALYSIS SHOW CAP WEAKEST ACROSS SOUTH CENTRAL OKLAHOMA AND WELL
WITHIN FAVORABLE SHEAR ENVIRONMENT. ANY FURTHER CAP EROSION WOULD
YIELD STRONGER UPDRAFT POTENTIAL TO SUPPORT THE HIGH SHEAR
ENVIRONMENT.

JUST SOUTHEAST OF THE FOUR CORNER REGION AND WAS MOVING EAST AS WELL.
ELEVATED SHOWER AND THUNDERSTORM ACTIVITY HAS BEEN OCCURRING ACROSS THE
REGION NORTH OF THE WARM FRONT. DESPITE STRONG SHEAR IN PLACE...SEVERE
WEATHER OVERNIGHT HAS BEEN LIKELY PRECLUDED BY THE LACK OF
INSTABILITY. HOWEVER...SEVERE CHANCES WILL INCREASE AS THE DAY
PROGRESSES AS THE WARM FRONT LIFTS NORTH...AND THE COLD FRONT
MOVES EAST. WHILE SEVERE WEATHER POTENTIAL EXISTS AREAWIDE WITH
DAMAGING DOWNBURST WINDS THE LIKELY THREAT...SOUTHEAST OKLAHOMA
HAS SLIGHTLY IMPROVED CHANCES FOR SEVERE STORMS...INCLUDING
TORNADOES...AS THIS AREA WILL BE IN THE WARM SECTOR AND WILL
BENEFIT FROM HIGHEST INSTABILITY AND MAXIMIZED DIRECTIONAL SHEAR.
THE SEVERE WEATHER THREAT WILL SHIFT EAST THIS EVENING...WITH
OVERALL CHANCES FOR STORMS DECREASING AFTER MIDNIGHT AS THE COLD
FRONT ADVANCES THROUGH THE AREA.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
ACTIVATION OF THE REGIONAL SPOTTER NETWORK LIKELY.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
FRIDAY THROUGH WEDNESDAY...NO HAZARDS.

EXTENDED DISCUSSION...
A BENIGN WEATHER PATTERN WILL OVERTAKE THE AREA IN THE WAKE OF THE
SYSTEM CURRENTLY AFFECTING THE REGION. THUNDERSTORM CHANCES FOR
THIS OUTLOOKED PERIOD WILL BE MINIMAL.
