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 Wichita, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at May 6, 6:02 PM CDT, 1 hour 52 minutes earlier.

Area forecast discussion, May 6, 6:02 PM CDT, 1 hour 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
602 PM CDT SUN MAY 6 2012

.AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU

ISOLATED TO WIDELY SCATTERED THUNDERSTORMS WILL REMAIN POSSIBLE
ALONG AND EAST OF A SLOW MOVING COLD FRONT ACROSS SOUTHEAST
KANSAS. FOLLOWING THE FRONT...A PERIOD OF MVFR CIGS IS ANTICIPATED
THROUGH 10-15Z ACROSS CENTRAL AND SOUTH CENTRAL KANSAS POSSIBLY
LINGERING THROUGH EARLY AFTERNOON ACROSS SOUTHEAST KANSAS BEFORE
VFR RETURNS. MAINTAINED VCTS AT KCNU AFTER 05Z BUT CONFIDENCE IN
MORE WIDESPREAD THUNDERSTORM ACTIVITY REMAINS LOW.

MWM

&&

.PREV DISCUSSION... /ISSUED 349 PM CDT SUN MAY 6 2012/

DISCUSSION...

TONIGHT:
MORE QUESTIONS THAN ANSWERS ON FORECAST. STORMS JUST STARTING TO
DEVELOP AND SMALL SCALE AREA OF DEEP MIXING HAS RESULTED IN
DRYLINE WORKING INTO EXTREME SOUTH CENTRAL KS AHEAD OF FRONT. MADE
LAST MINUTE TWEAK TO GRIDS TO LOWER DEW POINTS FOR THIS.
PRECIPITATION SHOULD BE ON THE WANE FROM THE NORTHWEST DURING THE
NIGHT. GIVEN LESS THAN OPTIMAL WIND FIELD...SUSPECT SEVERE THREAT
WILL BE DURING THE EARLY EVENING WITH PRIMARILY ISOLATED DAMAGING WIND
GUSTS ON STORM COLLAPSE. GIVEN CURRENT WIND PROFILES...LARGE HAIL
APPEARS LESS LIKELY. LOCALLY HEAVY RAINFALL IS ALSO POSSIBLE.
SEVERE THUNDERSTORM WATCH IS COMING SHORTLY.

MON-WED:
FORECAST IS A BIT PROBLEMATIC THIS PERIOD. DESPITE FAIR AMOUNT OF
LOW LEVEL DRIER AIR ADVECTING INTO THE AREA AT THE START OF THE
PERIOD...FLOW ALOFT WITH AREA IN RIGHT REAR QUADRANT OF 300MB
SPEED MAXIMUM AND APPROACHING 500MB TROUGH SHOULD RESULT IN
SYNOPTIC SCALE LIFT. SUSPECT THERE WILL BE AT LEAST SCATTERED-
BROKEN MIDDLE AND HIGH CLOUDS DURING THE PERIOD. THIS COULD
SIGNIFICANTLY IMPACT TEMPERATURES...AND GIVEN INCREASING SUN
ANGLE...A QUICK SURGE IN TEMPERATURES IS POSSIBLE WITH A SHORT
BREAK IN THE CLOUDS. AND GIVEN THAT WE ARE NOT EXPECTING
WIDESPREAD SIGNIFICANT RAIFALL...EVAPORATION SHOULD NOT BE A BIG
FACTOR AT MOST LOCATIONS.

THU-SAT:
FRONTAL PASSAGE ON FRI NIGHT SHOULD BRING ANOTHER CHANCE OF RAIN
TO THE AREA. MODELS...ESPECIALLY ECMWF...HAVE STRUGGLED WITH LOW
LEVEL MOISTURE AND PRECIPITATION OVER THE PAST FEW RUNS. LATEST
ECMWF CAME IN QUITE A BIT DRIER THAN PREVIOUS RUN WHICH HAD BEEN
THE WETTEST OF THE PAST FEW. DOES APPEAR THAT SLIGHTLY COOLER AIR
WILL FILTER IN FOR THE WEEKEND. HOWEVER ABOVE NORMAL TEMPERATURES
APPEAR LIKELY FOR MOST OF THE PERIOD. -HOWERTON

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

WIDELY SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP AFTER 20Z ALONG
AND EAST OF A COLD FRONT THIS AFTERNOON WHILE SPREADING EASTWARD
THROUGH THE EVENING HOURS. MEANWHILE...AREAS OF POST-FRONTAL MVFR
CIGS WILL CONTINUE TO IMPACT PORTIONS OF CENTRAL KANSAS. GIVEN THE
SCATTERED NATURE OF THE THUNDERSTORMS...MAINTAINED VCTS AT KICT WHILE CARRYING
A PREVAILING GROUP AFTER 02Z AT KCNU WHERE CONFIDENCE IS HIGHEST.
GUSTY NORTH WINDS ARE ANTICIPATED BEHIND THE COLD FRONT WITH BRIEF GUSTS
TO 30 KNOTS POSSIBLE.
