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

Springfield, MO (KSGF), launched 12:00Z, 11.6 hours before the alert went out and 42 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.

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 Springfield, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Oct 11, 2:20 PM CDT, 4 hours 13 minutes earlier.

Area forecast discussion, Oct 11, 2:20 PM CDT, 4 hours 13 minutes before

AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
220 PM CDT TUE OCT 11 2011

.DISCUSSION...

MODELS ARE IN GENERAL AGREEMENT ON THE OVERALL SYNOPTIC PATTERN
OVER THE NEXT THREE DAYS. SOME MUCH NEEDED RAINFALL COULD BE IN
THE OFFERING. EXPECT ON THE ORDER OF A QUARTER OF AN INCH OVER MOST
OF THE AREA THROUGH WEDNESDAY EVENING.

A MODERATE TO WEAK BROAD UPPER LEVEL TROUGH OVER THE PLAINS STATES
WILL CONTINUE TO TRACK EASTWARD INTO THE AREA THROUGH WEDNESDAY.
THIS FEATURE WILL BRING A RISK OF SHOWER ACTIVITY TO THE AREA.

MORE NOTABLY...A POTENT SPEED MAX...VIEWED ON THE ANIMATED WATER
VAPOR IMAGERY OVER THE PACIFIC NORTHWEST...WILL RAPIDLY CROSS THE
INTER-MOUNTAIN REGION AND APPROACH THE OZARKS WITH TIME. THIS
SYSTEM...ALONG WITH ITS ASSOCIATED SURFACE COLD FRONT...WILL BRING
THE BEST SHOT OF PRECIPITATION AND CONVECTIVE ACTIVITY TO THE
REGION WEDNESDAY AFTERNOON AND EVENING.

AT THIS POINT...DUE TO THE LACK OF LOW LEVEL WIND SHEAR...WE DO
NOT EXPECT ANY SIGNIFICANT CHANCE OF SEVERE WEATHER...HOWEVER...A
FEW ISOLATED STRONG TO MARGINALLY SEVERE STORMS CANNOT BE RULED OUT.

AFTER THE FRONTAL PASSAGE LATE WEDNESDAY...A BROAD UPPER LEVEL
RIDGE WILL BUILD BACK OVER THE DESERT SOUTHWEST KEEPING THE AREA IN
A DRY PATTERN. WARM TEMPERATURES WILL ALSO ACCOMPANY THIS SCENARIO
INTO EARLY NEXT WEEK. EVEN THOUGH THE RIDGE FLATTENS OUT SOMEWHAT
OVER THE WEEKEND...ANY SHORTWAVE ACTIVITY APPEARS TO REMAIN WELL TO
THE NORTH OF THE OZARKS THROUGH MONDAY.

PER GFS...WE MAY SEE A SECOND CHANCE OF RAIN ON TUESDAY AS A RIDGE
OVER THE WEST COAST STATES AMPLIFIES AND FLOW BECOMES MORE
MERIDIONAL. THE GFS SUGGESTS THAT A FAIRLY VIGOROUS SHORTWAVE
DIVING SOUTHWARD FORM CANADA COULD CREATE A ROUND OF SHOWERS AND
THUNDERSTORMS NEXT TUESDAY. THE ECMWF PORTRAYS A MORE ZONAL
PATTERN AND KEEPS THE STRONGEST SHORT WAVE SUPPORT AND MOST OF THE
PRECIPITATION TO OUR EAST. WE WILL JUST HAVE TO WAIT TO SEE IF
MODELS COME INTO PHASE ON THIS PATTERN FOR EARLY NEXT WEEK.

.AVIATION...
/ISSUED 1242 PM CDT TUE OCT 11 2011/

FOR THE 11/1800Z KSGF/KJLN/KBBG TAFS...A DISTURBANCE LIFTING NNE
THROUGH THE REGION TODAY IS PRODUCING AN AREA OF SHOWERS AND ISOLD
TSTMS. VFR CEILINGS...POSSIBLY BRIEFLY HIGH END MVFR AT TIMES WILL
OCCUR. ISOLATED VERY BRIEF HEAVIER SHOWERS WILL ALSO REDUCE
VISIBILITY TO THE MVFR AND EVEN IFR CATS ON A LOCALIZED BASIS
EARLY IN THE TAF PERIOD. AFTER 00Z...CONTINUED WITH THE PREVIOUS
FORECAST OF VFR CONDITIONS. PROGGED SOUNDINGS SHOW FAIRLY EXTENSIVE
MID LEVEL CLOUDS TONIGHT AHEAD OF AN APPROACHING COLD FRONT.
SHOWERS/ISOLD TSTMS WILL LIKELY BECOME MORE NUMEROUS LATE IN THE
TAF PERIOD AS THE FRONT MOVES INTO EASTERN KS.
