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, 5.7 hours before the alert went out and 84 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, Oct 8, 11:37 AM CDT, 1 hour 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1137 AM CDT MON OCT 8 2007

.DISCUSSION...

THE COLD FRONT CONTINUES TO MAKE DECENT HEADWAY ACROSS THE
REGION...CURRENTLY EXTENDING FROM JUST WEST OF VICHY TO JUST WEST
OF BRANSON. A VERY NARROW...BROKEN BAND OF CONVECTION CONTINUES TO
LINE UP ALONG/JUST BEHIND THE SURFACE FRONT. A SLIGHTLY LESS
NARROW BAND OF POST FRONTAL RAIN EXTENDS FROM NEAR WARSAW THROUGH
ANDERSON. THE MOVEMENT OF THIS SYSTEM MIMICS THE 4KM WRF QUITE
WELL AND HAVE FOLLOWED ITS LEAD ACCORDINGLY FOR THE REST OF TODAY.

RAINFALL HAS ALREADY MOVED OUT OF THE VICINITY OF THE MO/KS BORDER
AND WILL MAINTAIN A DRY AFTERNOON HERE. PERIODS OF SHRA/TSRA WILL
CONTINUE FROM THE LAKE OZARK/VICHY AREA SOUTHWESTWARD THROUGH THE
SPRINGFIELD AND BRANSON AREAS THROUGH ABOUT MID AFTERNOON. POINTS
EASTWARD CAN EXPECT PERIODS OF SHRA/TSRA FOR MOST OF THE AFTERNOON.

TEMPERATURES WILL BE A LITTLE TRICKY TODAY GIVEN CLOUD
COVERAGE/RAIN. HIGHS SHOULD BE REACHED OVER THE EASTERN OZARKS
WITHIN THE HOUR...THEN FALL OFF INTO THE LOWER 70S AFTER RAINFALL
SPREADS OVER THE AREA. HIGHS HAVE ALREADY BEEN REACHED FROM THE
LAKE OZARK/VICHY AREA BACK THROUGH SPRINGFIELD AND BRANSON. SOME
RECOVERY IS EXPECTED AFTER THE RAIN MOVES OUT OF THE AREA...BUT
TEMPS SHOULD STAY IN THE 70S FOR THE MOST PART. OVER WESTERN
ZONES...TEMPS HAVE BEEN THWARTED DUE TO EARLY CLOUDS/RAIN...
HOWEVER SOME CLEARING IS EXPECTED AND TEMPS SHOULD BE ABLE TO EDGE
BACK INTO THE LOWER 70S.

WILL CONTINUE TO MONITOR HOURLY TRENDS AND TWEAK AS NEEDED.
RAINFALL SHOULD BE OUT OF THE EASTERN OZARKS BY SUNSET.
