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

Dodge City, (KDDC), launched 12:00Z, 11.8 hours before the alert went out and 148 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 22, 6:30 PM CDT, 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
630 PM CDT FRI JUL 22 2011

.AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
ISOLATED-SCATTERED THUNDERSTORMS LIKELY TO PERSIST THROUGH MID
EVENING ACROSS CENTRAL AND SOUTHWEST KS. WILL UTILIZE TEMPO TS AT
RSL WITH CB CLOUD GROUPS AT HUT AND SLN WHICH HAVE A LESSER
PROBABILITY OF A DIRECT HIT. GUSTY WINDS WILL BE THE MAIN CONCERN
NEAR ANY OF THESE STORMS. OTHERWISE...VFR CONDITIONS OUTSIDE OF
ANY STORMS TONIGHT INTO SATURDAY.

JMC

&&

.PREV DISCUSSION... /ISSUED 323 PM CDT FRI JUL 22 2011/

DISCUSSION...

TONIGHT:
ISOLATED CONVECTION WILL LIKELY PERSIST UNTIL AROUND SUNSET IN
CENTRAL KANSAS. OTHERWISE EXPECT DRY CONDITIONS AND MILD/WARM
TEMPERATURES.

SAT-SAT NIGHT:
WILL CONTINUE SMALL CHANCES FOR LATE AFTERNOON/EVENING
THUNDERSTORMS IN CENTRAL KS...AND THIS IS DEPENDENT ON CONVECTION
FRI NIGHT LEAVING ENOUGH OF A BOUNDARY TO INITIATE STORMS.
OTHERWISE NO REAL CHANGE IN TEMPERATURES/HEAT INDICES.

SUN-SUN NIGHT:
UNCLEAR WHY NAM/GFS HAVE BEEN SO AGRESSIVE BREAKING OUT CONVECTION
SUN AFTER/EVENING...GIVEN THAT HEIGHTS/TEMPERATURES ALOFT ARE NOT
CHANGING SIGNIFICANTLY. CHANCES DO APPEAR TO INCREASE A BIT SUN
NIGHT...WITH A 850MB BAROCLINIC ZONE CUTTING ACROSS NE KS. NE
SECTIONS OF FORECAST AREA COULD GET CLIPPED BY STORMS DURING THE
NIGHT...BUT WESTWARD EXTENT IS VERY QUESTIONABLE. GIVEN LATEST
TEMPERATURE/DEWPOINT FORECASTS...WILL EXTEND EXCESSIVE HEAT
WARNING ANOTHER DAY AREAWIDE.

MON-FRI:
GIVEN LITTLE IF ANY CHANGE IN FORECAST HEIGHTS THROUGHOUT THE
PERIOD...DO NOT ANTICIPATE ANY SIGNIFICANT RELIEF FROM ONGOING
HEAT WAVE...WITH TRIPLE DIGITS LIKELY OVER MOST OF THE AREA EACH
DAY. AFTERNOON HEAT INDICES WILL ALSO BE IN THE TRIPLE DIGITS EACH
DAY OVER MOST LOCATIONS...AND HEADLINES WILL LIKELY BE NEEDED.
THERE IS A CHANCE THAT OUTFLOW AND/OR FRONT WILL WORK INTO
CENTRAL KS LATE WEEK...BUT TIMING AND HOW FAR SOUTH BOUNDARY WILL
GO IS QUESTIONABLE. BEST ESTIMATE AT THIS TIME FOR PRECIPITATION
IN CENTRAL KS IS ON THU NIGHT. -HOWERTON

AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU

MAIN AVIATION FORECAST CONCERN IS THE CHANCES FOR THUNDERSTORMS IN
CENTRAL KANSAS THIS AFTERNOON.

VFR CONDITIONS ARE EXPECTED TO CONTINUE THROUGH THE FORECAST
PERIOD FOR ALL TAF SITES. THERE IS A CHANCE FOR THUNDERSTORMS THIS
AFTERNOON THAT COULD IMPACT KRSL AND KSLN. THE BEST CHANCE FOR
THESE ISOLATED STORMS WILL BE AT KRSL AND HAVE INCLUDED A CB GROUP
FOR THE AFTERNOON HOURS. CONFIDENCE WAS NOT HIGH ENOUGH TO INCLUDE
A FULL TEMPO OR FM GROUP AT THIS TIME. OTHERWISE...EXPECT
SOUTH TO SOUTHEASTERLY WINDS TO PREVAIL UNDER MOSTLY CLEAR SKIES.
