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

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 Jun 12, 3:35 PM CDT, 7 hours 22 minutes earlier.

Area forecast discussion, Jun 12, 3:35 PM CDT, 7 hours 22 minutes before

AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
335 PM CDT WED JUN 12 2002

WENT AHEAD AND ISSUED FLOOD WATCH FOR ALL OF THE FORECAST AREA
THROUGH NOON THURSDAY. STILL A LITTLE TOO MUCH UNCERTAINTY NOW TO
TRY PINNING DOWN TRACK OF MCS ACTIVITY TONIGHT. UPDATED ZONES WILL
BE OUT SHORTLY.

(PREVIOUS DISCUSSION ATTACHED)

MAIN FORECAST ISSUES ARE HEAVY RAIN AND SEVERE POTENTIAL FOR
TONIGHT...AND WHETHER OR NOT TO EXTEND AREAL COVERAGE OF FLOOD WATCH
FOR TONIGHT.

LATEST RADAR SHOWS NORTHERN PORTION OF SECONDARY MCS OVER SOUTHWEST
COUNTIES THIS AFTERNOON. ALSO SEE A FEW STORMS POPPING UP ALONG OUR
WESTERN BORDER AND OVER SOUTH CENTRAL MO. MORNING CONVECTION HAS
LAID OUT SEVERAL OUTFLOW BOUNDARIES. THE MOST OBVIOUS ONE EXTENDS
ACROS NORTHEAST OK TO WEST CENTRAL AR. OTHER MORE SUBTLE BOUNDARIES
EXTEND BETWEEN OSAGE BEACH AND FORT WOOD...AND OVER SOUTHEAST KS.
DEWPOINT TEMPERATURES ARE IN THE LOWER TO MIDDLE 70S WITH A FEW MID
TO UPPER 60S IN RAIN COOLED AIR NEAR JOPLIN. MAIN UPPER LEVEL
SUPPORT FOR CURRENT MCS IS EXITING EASTERN COUNTIES AT THIS TIME.

AT LEAST FOR THE REST OF THE AFTERNOON AND INTO EARLY
EVENING...EXPECT SCATTERED STORMS WITH HEAVY RAINFALL TO FIRE UP
JUST ABOUT ANYWHERE IN THE FORECAST AREA...AS BREAKS IN
CLOUDS...ESPECIALLY OVER EASTERN SECTIONS...HAVE AIDED
DESTABILIZATION...AND PRECIPITABLE WATER VALUES REMAIN OVER 1.7
INCHES.

POTENTIAL FOR HEAVY RAIN CONTINUES TONIGHT WITH AN MCS OR TWO
DEVELOPING SOMEWHERE IN THE CENTRAL PLAINS THIS EVENING AND MOVING
EAST AROUND UPPER RIDGE. BASED ON LATEST SATELLITE TRENDS AND MODEL
DATA...THERE COULD BE TWO COMPLEXES AFFECTING THE AREA TONIGHT. ONE
WHICH WILL DEVELOP OVER NORTHERN KS/SOUTHERN NE AND CLIP CENTRAL
MO...AND ANOTHER DEVELOPING OVER SOUTHWEST KS/NORTHERN OK AND MOVING
OVER ALREADY SATURATED SOUTH/WEST EDGE OF THE CWA. ALREADY HAVE A
FLOOD WATCH GOING FOR THE WESTERN TWO TIER OF COUNTIES AND MAY
SPREAD WATCH EASTWARD ACROSS THE REST OF THE FORECAST AREA FOR
TONIGHT AND THURSDAY MORNING.

SURFACE FRONT STILL HUNG UP OVER NORTHWEST MO/SOUTHEAST NE WILL MOVE
ACROSS OUR AREA TOMORROW...WITH COOLER AN DRIER CONDITIONS THROUGH
SATURDAY.

WENT AHEAD AND PUT POPS IN FOR SUNDAY AND MONDAY. OVERALL TREND HAS
BEEN TO SHIFT UPPER TROUGH WESTWARD...PUTTING OUR AREA UNDER MORE
CYCLONIC FLOW. AVN ALSO HINTS AT POSSIBLE DUAL JET STRUCTURE
FAVORABLE FOR GOOD LIFT OVER THE AREA. ONLY QUESTION WILL BE WHETHER
OR NOT ENOUGH MOISTURE MAKES IT BACK THIS FAR NORTH.

FCSTID = 17/MMT

.SGF...
MO...FLOOD WATCH NOON THURSDAY FOR ZONES
MOZ055>058...MOZ066>071...MOZ077>083...MOZ088>098...MOZ101>106.

KS...FLOOD WATCH NOON THURSDAY FOR ZONES KSZ073...KSZ097...KSZ101.
