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, 7.9 hours before the alert went out and 228 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, May 15, 2:30 PM CDT, 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
230 PM CDT TUE MAY 15 2007

.DISCUSSION...

CURRENTLY...SURFACE COLD FRONT LOCATED IN THE CWA ALONG A LINE FROM
ROLLA TO SEYMOUR TO JUST EAST OF CASSVILLE. AHEAD OF THE
FRONT...MARGINALLY SEVERE THUNDERSTORMS...VERY EFFICIENT RAIN
PRODUCERS ARE OCCURRING. BEHIND THE FRONT...CONDITIONS ARE
STABILIZING. ONE LAST AREA OF SHOWERS MOVING INTO SOUTHEAST KANSAS
AND WESTERN MISSOURI. ARE GETTING SOME CELLS DEVELOPING OVER NEWTON
AND MCDONALD COUNTIES AND HAVE ADDED SOME SLT CHC TSTMS TO THE
FORECAST THIS AFTERNOON. SINCE THE AREA IS MOVING INTO A WORKED OVER
ENVIRONMENT...DO NOT THINK THIS AREA WILL REDEVELOP MUCH AT ALL FROM
WHAT WE ARE SEEING NOW. WILL CONTINUE TO WATCH DEVELOPMENT OF THIS
AREA. IF WE GET ANY CLOUD BREAKS TO ALLOW SOME SURFACE
HEATING...FURTHER THUNDERSTORM DEVELOPMENT COULD OCCUR.

FRONT CONTINUES TO MOVE OFF TO THE EAST THIS EVENING AND ALL PRECIP
SHOULD END AFTER ABOUT 03Z. WITH SKIES CLEARING AND WINDS FAIRLY
LIGHT...COULD SEE SOME PATCHY FOG DEVELOPING AFTER ABOUT 09Z THROUGH
SUNRISE. MODEL SOUNDINGS SHOWING DRYING OF LOWER LEVELS...BUT
BELIEVE MODELS MAY BE TOO FAST BRINGING THIS DRY AIR INTO THE AREA.
SURFACE DEWPOINTS OVER EASTERN KANSAS STILL IN THE MID TO UPPER 50S.
DO NOT SEE LOWER DEWPOINTS UNTIL YOU GET INTO SOUTHERN NEBRASKA AND
WEST CENTRAL KANSAS CURRENTLY. SO WILL GO AHEAD AND MENTION PATCHY
DENSE FOG IN THE FORECAST FOR OVERNIGHT.

NORTHERLY FLOW ON TAP FOR WEDNESDAY AS UPPER LOW MOVES OFF INTO
NORTHERN INDIANA. EXPECTING LOW TO MID 70S FOR HIGHS WITH MOSTLY
SUNNY SKIES. LOOKS LIKE REST OF WEEK SHOULD BE DRY WITH A WARMING
TREND BY SATURDAY.

GCC

.AVIATION...

FOR THE 18Z TAFS...
COLD FRONT HAS MOVED THROUGH BOTH THE KJLN AND KSGF TERMINALS.
EXPECTING VFR CONDITIONS FOR BOTH LOCATION INTO THIS AFTERNOON
BEFORE BECOMING MVFR AROUND 22-01Z AS CEILINGS AND VISIBILITIES DROP
BEHIND THE FRONT. THIS WILL CONTINUE OVERNIGHT THROUGH EARLY
WEDNESDAY MORNING AS LOW LEVEL MOISTURE IMPACTS VISIBILITIES CAUSING
MVFR CONDITIONS AT BOTH TAF SITE AGAIN. VFR CONDITIONS WILL THEN
PREVAIL AFTER 11-12Z FOR THE REGION AS DRIER AIR MOVES INTO THE
REGION.
