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, 3.4 hours before the alert went out and 224 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
NATIONAL WEATHER SERVICE ST LOUIS MO
445 AM CST WED NOV 29 2006
.DISCUSSION...
...MAJOR WINTER STORM WILL BEGIN TO AFFECT REGION TONIGHT...
MODEL GUIDANCE HAS COME INTO BETTER AGREEMENT ON LARGE SCALE
FEATURES CONCERNING THE COLD FRONT AND DEVELOPING WINTER STORM
SCENARIO...BUT STILL EXHIBIT SOME DIFFERENCES IN THE DETAILS.
COLD FRONT CURRENTLY EXTENDS FROM NEAR PLEASANT HILL TO KIRKSVILLE
WITH SHOWERS AND THUNDERSTORMS DEVELOPING ALONG AND AHEAD OF THE
FRONT.
STILL BELIEVE NAM IS BEST MODEL TO FOLLOW WHEN FOCUSING ON
THERMODYNAMICS OF THE LOWEST LEVELS OF THE ATMOSPHERE AND HAVE
THEREFORE FOLLOWED ITS TIMING OF THE FRONT AND FREEZING LINE ACROSS
THE CWA AS WELL AS TURNOVER TO SNOW.
THE COLD FRONT WILL CONTINUE TO MOVE SOUTHEAST ACROSS THE CWA DURING
THE NEXT 24 HOURS...USHERING IN THE COLDEST AIR OF THE SEASON. RAIN
WILL BEGIN TO FREEZE ON ELEVATED SURFACES ACROSS NORTHWEST SECTIONS
OF THE CWA AS EARLY AS THIS EVENING WITH FREEZING RAIN BECOMING
LIKELY ACROSS PARTS OF CENTRAL MISSOURI AFTER MIDNIGHT.
FREEZING LINE TO MOVE THROUGH ST. LOUIS METRO AREA AROUND 8 AM ON
THURSDAY WITH THE ENTIRE CWA BELOW FREEZING BY THE LATE AFTERNOON.
AS THE COLD AIR DEEPENS...THE RAIN WILL BEGIN TO MIX WITH SLEET AND
EVENTUALLY TURN TO ALL SNOW BY THURSDAY EVENING. SIGNIFICANT ICE
ACCUMULATIONS...ESPECIALLY ON ELEVATED SURFACES SUCH AS TREES AND
POWERLINES WILL LIKELY OCCUR ACROSS CENTRAL AND EASTERN MISSOURI AS
WELL AS WEST CENTRAL ILLINOIS.
ALL MODELS AGREE THAT A STRONG SHORTWAVE ROUNDING THE BASE OF THE
LARGE SCALE TROF WILL INDUCE CYCLOGENESIS ALONG THE FRONTAL BOUNDARY
WITH A CLASSIC DEFORMATION ZONE SETTING UP ALONG OR JUST NORTH OF
THE I-44 CORRIDOR THURSDAY NIGHT. BUFKIT REVEALS ELEVATED CAPE AND
THEREFORE THE CHANCE OF THUNDERSNOW. HAVE FORECASTED SNOW TOTALS
UP TO 10 INCHES IN A BAND THAT LIES JUST NORTH OF I-44 IN MISSOURI
AND I-70 IN ILLINOIS. WOULD NOT BE SURPRISED TO SEE SOME LOCATIONS
RECEIVE MORE THAN A FOOT IF THUNDER OCCURS.
PLAN ON EXTENDING THE WINTER STORM WATCH FOR TONIGHT TO INCLUDE
CENTRAL MISSOURI...OTHERWISE WILL LET DAYSHIFT GET ONE MORE MODEL
RUN UNDER THERE BELT BEFORE ISSUING WINTER STORM WARNINGS.
WINTER STORM EXITS REGION FRIDAY MORNING WITH COLD TEMPERATURES LEFT
IN ITS WAKE. LOOK FOR SINGLE DIGIT READINGS SATURDAY MORNING AS HIGH
PRESSURE OVER A FRESH SNOW PACK RESULTS IN FAVORABLE RADIATIONAL
COOLING.
CVKING
&&
.AVIATION...
FOR THE 12Z TAFS...
AN ARCTIC COLD FRONT EXTENDED FROM NORTHEAST IA ACROSS WESTERN MO
INTO THE TX PANHANDLE EARLY THIS MORNING...NEAR A DBQ-IRK-PNC LINE.
THE FRONT WILL CONTINUE TO SAG SLOWLY SOUTHEASTWARD DURING THE
PERIOD. MOST OF THE CONVECTION CONTINUED FROM WEST CENTRAL INTO
NORTHEAST MO. THE SHOWERS/SCATTERED THUNDERSTORMS WERE MOVING TO THE
NORTHEAST. THREE HOURLY SURFACE PRESSURE CHANGE MAP INDICATED A 4 MB
RISE CENTER OVER SOUTHEAST NEB. COLD FRONT WAS MOVING FASTER THAN
THE PREVIOUS MODEL GUIDANCE. THE LATEST NAM GUIDANCE ON BUFKIT
SOUNDINGS INDICATED THE RAIN WOULD CHANGE TO FREEZING RAIN AT UIN
AROUND 09Z TONIGHT AND AT COU AROUND 10Z TONIGHT. THE 00Z RUN OF THE
NAM CHANGED DROPPED THE TEMP TO FREEZING 2 TO 3 HOURS SOONER.
WIDESPREAD IFR CONDITIONS WILL DEVELOP BEHIND THE FRONT AS IT SLIDES
ACROSS THE AREA.
