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, 11.1 hours before the alert went out and 219 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...CORRECTED FOR ISSUANCE TIME
NATIONAL WEATHER SERVICE SPRINGFIELD MO
334 PM CDT TUE MAY 25 2004

.DISCUSSION

SHORT TERM (THIS AFTERNOON - THURSDAY)...
A STALLED OUT COLD FRONT WILL BE THE PRIMARY FOCUS FOR ACTIVE
WEATHER TONIGHT.  PER PROFILER NETWORK...CONVECTION THAT DEVELOPED
TODAY WAS MAINLY ALONG THE 850 MB MASS CONVERGENCE ZONE...NORTH OF
THE SURFACE FRONT.  THE SURFACE FRONT CAN BE SEEN ON RADAR EXTENDING
FROM EXTREME SOUTHWEST MISSOURI...BASICALLY ALONG THE INTERSTATE 44
CORRIDOR UP TO ST LOUIS.  MASS CONVERGENCE ALONG WITH ISENTROPIC
UPSLOPE UP THE BAROCLINIC ZONE WILL ALLOW SHOWERS AND THUNDERSTORMS
TO CONTINUE THROUGH MUCH OF TONIGHT.  THE THREAT FOR SEVERE WEATHER
ALSO CONTINUES...ESPECIALLY OVER SOUTH CENTRAL MISSOURI WHERE 100 MB
MIXED LAYER CAPES ARE EXCEEDING 2500 J/KG.  STORMS THAT FIRE IN THIS
ENVIRONMENT SHOULD BECOME SEVERE WITH LARGE HAIL AND FLOODING
BECOMING THE PRIMARY HAZARDS.  WILL ADJUST POP GRIDS TO THE LIKELY
CATEGORY FOR TONIGHT ACROSS THE ENTIRE CWA.

FOR TOMORROW...NOT A WHOLE LOT WILL CHANGE WITH SCATTERED SHOWERS
AND THUNDERSTORMS CONTINUING OVER THE SAME AREAS AS TONIGHTS
ACTIVITY WILL SET UP.  WILL CONTINUE THE FLOOD WATCH FOR AREAS ALONG
AND NORTH OF A LINE FROM FORT SCOTT KANSAS TO SALEM MISSOURI.

BY THURSDAY...THE ETA BRINGS SOUTHERLY WINDS BACK INTO THE AREA AND
SOMEWHAT WASHES OUT THE FRONT.  THE GFS SEEMS A LITTLE MORE
REASONABLE WITH THIS SOLUTION KEEPING THE BOUNDARY ACROSS THE CWA
INTO THE WEEKEND.

LONG TERM (FRIDAY - MONDAY)...
GFS CONTINUES TO INDICATE THE MEANDERING OF A QUASI-STATIONARY
BOUNDARY THROUGH CENTRAL AND SOUTHERN MISSOURI INTO THE WEEKEND.
THEREFORE...AREA INTERESTS CAN EXPECT MORE ACTIVE WEATHER.  THIS
FEATURE WILL BE THE FOCUS FOR BOTH DIURNAL AND NOCTURNAL CONVECTION
ON A DAILY BASIS.

BOTH MRF AND THE GFS ARE CONSISTENT WITH SURGING THE FRONT NORTH OF
THE REGION BY SATURDAY OR SUNDAY...IN RESPONSE TO DEEPENING LOW
PRESSURE LEE OF THE ROCKIES.  THIS WILL ULTIMATELY WARM TEMPERATURES
UP AND LESSEN PRECIPITATION CHANCES.

CRAMER

&&

.AVIATION...
FRONTAL BOUNDARY WILL CONTINUE TO SLOWLY SAG SOUTH TONIGHT. FRONT
HAS ALREADY MADE IT THROUGH JOPLIN WHERE POST FRONTAL IFR CONDITIONS
ARE OCCURRING THIS AFTERNOON. EXPECT THUNDERSTORMS TO BECOME MORE
NUMEROUS AT KSGF AND KJLN AS FRONTAL BOUNDARY CONTINUES TO SAG SOUTH
AND LOW LEVEL MOISTURE RIDES UP AND OVER IT THIS EVENING.
THUNDERSTORMS SHOULD CONTINUE WELL INTO THE MORNING HOURS WEDNESDAY.

DSA

.SGF WATCHES/WARNINGS/ADVISORIES...
MO...FLOOD WATCH THROUGH WEDNESDAY AFTERNOON NORTH OF A LINE FROM
NEVADA TO SALEM.
KS...FLOOD WATCH THROUGH WEDNESDAY AFTERNOON FOR BOURBON COUNTY.
