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, May 23, 2:48 PM CDT, 1 hour 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
248 PM CDT SUN MAY 23 2004

...MESOSCALE CONVECTIVE DISCUSSION...

.DISCUSSION...

FAIRLY STRONG SURFACE LOW (999MB) CONTINUES TO LIFT NORTHEAST INTO
SOUTHERN WISCONSIN WITH A TROUGH/WEAK DRYLINE STRETCHING SOUTHWEST
FROM THE LOW THROUGH UIN TO NEAR PPF AS OF 19Z. ACROSS OUR CWA WINDS
HAVE ALREADY VEERED TO AROUND 220-230 AHEAD OF THE TROUGH...WHICH IS
MINIMIZING LOW LEVEL CONVERGENCE ALONG THE BOUNDARY. SPECIAL LOCAL
18Z SOUNDING CONTINUED TO SHOW A STRONG CAPPING INVERSION WITH
MLCINH WELL IN EXCESS OF NEARLY 200 J/KG.

STRONGER LOW LEVEL CONVERGENCE AND IN ALL LIKELIHOOD WEAKER CINH HAS
ALLOWED FOR CONVECTION TO BEGIN TO FIRE ALONG THE BOUNDARY FROM
CENTRAL MISSOURI NORTHWARD INTO NE MO...HOWEVER THUS FAR UPDRAFTS
HAVE BEEN STRUGGLING TO SUSTAIN THEMSELVES (PROBABLY DUE IN PART TO
THE RELATIVELY WEAK LL CONV). A BIT OF CLEARING AHEAD OF THE LINE
MAY ALLOW FOR A MORE DESTABILIZATION OVER OUR NORTHEASTERN MOST
COUNTIES...SO IT ISNT OUT THE QUESTION THAT A COUPLE OF THE STORMS
MAY YET BECOME MORE ORGANIZED BEFORE THE AFTERNOON IS OVER.

IF UPDRAFTS DO BECOME MORE ORGANIZED THEN THE STRONG (ALBEIT
UNIDIRECTIONAL) SHEAR COMBINED WITH MODERATE INSTABILITY WOULD BE
ENOUGH OR ONE OR TWO SEVERE THUNDERSTORMS OVER NORTHEASTERN
PORTIONS OF OUR CWA. PRIMARY THREAT WOULD LIKELY BE LARGE HAIL AND
POSSIBLY LOCALLY DAMAGING WINDS. TORNADO THREAT APPEARS TO BE VERY
LOW THIS FAR SOUTH WITH WINDS ALREADY SO BACKED.

.SGF WATCHES/WARNINGS/ADVISORIES...
MO...NONE.
KS...NONE.
