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.

Area forecast discussion, Jul 13, 2:20 PM CDT, 4 hours 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
220 PM CDT FRI JUL 13 2012

.DISCUSSION...

CURRENTLY HAVE THE FORECAST AREA IN BETWEEN A COUPLE OF UPPER
LEVEL SHEAR AXIS...ONE TO THE SOUTHEAST OF THE AREA AND THE OTHER
NORTHWEST OF THE CWA. THE ONE TO THE SOUTHEAST OF THE AREA HAS
BEEN LESS ACTIVE THAN THE PAST COUPLE OF DAYS. THE NORTHWEST AXIS
ASSOCIATED WITH AN UPPER LEVEL SHORTWAVE HAS TRIGGERED A BAND OF
SCATTERED STORMS FROM EXTREME SOUTHEAST KANSAS TO NEAR CHICAGO IL.

NOT MUCH IN THE WAY OF BULK SHEAR TO ORGANIZE THESE STORMS HOWEVER
OUR THETA-E DIFFERENCES IN THE VICINITY OF THE STORMS IS FROM 25
TO 30 K SO WILL NEED TO MONITOR FOR DOWNDRAFT WINDS WITH THE
STRONGER STORMS. HAVE INCLUDED A LIMITED WIND RISK IN THE LATEST
HWO FOR THIS AFTERNOON. MOVEMENT OF THE STORMS WILL BE VERY SLOW
DUE TO THE LIGHT MID LEVEL WINDS AND VERY HEAVY RAINFALL WILL
OCCUR WHERE THE STORMS OCCUR. THE STORMS ARE EXPECTED TO DISSIPATE
BY THE EARLY TO MID EVENING WITH THE LOSS OF DAYTIME HEATING AND
DECREASED INSTABILITY.

UPPER LEVEL SHEAR AXIS TO THE NORTHWEST WILL MEANDER OF THE AREA
THROUGH SUNDAY NIGHT AND WILL LIKELY BRING DIURNAL CONVECTION
SIMILAR TO TODAY AHEAD OF THIS FEATURE WHICH WOULD BE MOST LIKELY
OVER THE SOUTHEAST HALF OF THE FORECAST AREA. MEANWHILE...UPPER
LEVEL RIDGE WILL ALSO BE BUILDING INTO THE AREA FROM THE WEST WITH
850 TEMPERATURES IN THE UPPER TEENS TO LOW 20S EXPECTED TO ADVECT
INTO THE AREA. WITH GENERALLY DRY CONDITIONS EXPECTED FOR THE
REMAINDER OF THE WEEK...HOT CONDITIONS WILL LIKELY RETURN...ALBEIT
NOT AS HOT AS THE PREVIOUS HEAT WAVE. STILL...HEAT INDEX VALUES OF
100 TO 105 WILL BE POSSIBLE FOR THE LATTER HALF OF NEXT WEEK.
