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

Lincoln, IL (KILX), launched 12:00Z, 10.7 hours before the alert went out and 226 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 INDIANAPOLIS IN
225 PM EST TUE JAN 8 2008

.DISCUSSION...UPPR PATTERN TO REMAIN PROGRESSIVE ACRS THE AREA FOR
THE NEXT FEW DAYS AS SYS CURRENTLY OVR THE SRN PLAINS MOVES RAPIDLY
NEWD ACRS THE LOCAL AREA THIS EVEN. THE NEXT DISTURBANCE OFF THE
PACIFIC NW CST IS XPCTD TO MOVE INTO THE MIDWEST BY THURS EVEN.
MODELS IN GOOD AGREEMENT WITH THE MAIN DETAILS. FCST FOCUS CENTERS
ON POPS.

IN THE NR TERM...WAVY CDFNT CURRENTLY ABOUT HALF WAY THRU IL WITH A
DVLPG SFC WV LOCATED OVR SERN MO. MODEL DATA SUGGEST THIS WV SHOULD
MOV NEWD INTO THE NW SECTIONS OF IND TOWARDS 09/00Z...WITH CD FROPA
IN THE 09/00Z-09/05Z TIME FRAME. MOST OF THE SFC INSTABILITY IN THE
LOCAL AREA HAS BEEN ERASED WITH WIDESPREAD PCPN. AS THE SFC WV
PASSES ACRS IL BY LT AFT...SOME SFC BASED INSTABILITY MAY BE ABLE TO
SNEAK BACK INTO THE SRN AREAS...HOWEVER MODELS SEEM TO HAVE
OVER-ESTIMATED SFC INSTABILITY UP TO THIS PT. SHEAR VALUES LOOK VRY
HI PRIOR TO FROPA...WITH BOTH A 50KT 850MB JET AXIS AND A 100KT
500MB JET AXIS BOTH CROSSING OVR THE AREA EARLY THIS EVENING. SVR
THREAT STILL PSBL AHEAD OF FROPA WITH ANY SFC BASED CONVECTION THAT
DVLPS. SOME CONCERN WITH HVY RAIN THREAT AS WELL GIVEN THAT
PRECIPITABLE WATERS ARE WELL ABV NORMAL...BUT GIVEN THE SPEED OF SYS
AND THE SHORT DURATION OF THE MOST SIG LIFT...DON/T THINK ANY
HEADLINES WL NEED TO BE EXTENDED. PCPN SHOULD SHUT OFF RATHER
QUICKLY AFT FROPA...BUT SOME LT PCPN PSBL AFT MIDNIGHT WITH MODELS
HINTING AT A WK DEFORMATION ZONE PASSING THRU LTR TONIGHT. PARTIAL
THICKNESSES SUGGESTING THE THREAT OF A CHANGE OVER TO SNOW HAS
DIMINISHED.

IMPRVG CONDS XPCTD WED/WED NIGHT IN THE WAKE OF DEPARTING SYS. NEXT
SYS BEGINS TO AFFECT THE AREA BY THURS...SO WL ADD CHC POPS AT THAT
TIME. PARTIAL THICKNESSES SUGGEST RAIN MOST LIKELY PCPN TYPE AT THIS
PT.

LO LVL THICKNESSES SUGGEST THE NGM MOS GUIDANCE COOL BIAS
CONTINUES...WITH THE GUIDANCE PSBLY ON THE ORDER OF 5-8 DEGS TO
COOL. AS A RESULT...WL BUMP UP THE NUMBERS IN THE WED-THURS TIME
PD.

.AVIATION DISCUSSION...FOR THE 18Z TAFS.
LATEST RADAR TRENDS SHOW SHRA ACRS MUCH OF CENTRAL INDIANA PUSHING
NE. PCPN APPEARS TO BE THINNING OUT ON THE WESTERN EDGE...AND THIS
SHUD ALLOW US TO START THE LAF AND HUF TAFS WITH VCSH. SWATH OF PCPN
OVR SRN IL SHUD KEEP IND AND BMG WET FOR AT LEAST THE FIRST FEW HRS
OF THE  TAF PERIOD WITH MVFR CONDITIONS.

STRONG NEGATIVE TILTED UPPER WAVE WL PUSH THROUGH INDIANA TONIGHT
ALONG WITH A CD FRONT AND ANOTHER ROUND OF PCPN IS EXPECTED THIS
EVENING AFT 23Z-01Z. ISOLATED TSRA AND BRIEF HEAVY RAINS WL BE
POSSIBLE  RESULTING IN BRIEF IFR CONDITIONS...BUT UNTIL WE CAN SEE
THINGS COMING WL JUST USE MVFR CONDITIONS IN THE TAFS FOR NOW.

AS THE CD FRONT DEPARTS LATE TONIGHT TIME SECTIONS ACRS THE AREA
SUGGEST THE COLUMN DRYING OUT CONSIDERABLY RESULTING IN A RETURN
