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, 9.1 hours before the alert went out and 161 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, Apr 11, 3:50 PM EDT, 1 hour 14 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 350 PM EDT WED APR 11 2007 .DISCUSSION...SFC ANALYSIS SHOWS A WARM FRONT OVR ERN IL EXTENDING SOUTH INTO SW IND. SFC LOW PRES OVR SE IA WILL CONTINUE TO MOVE TO THE NE WITH A N-S ORIENTED COLD FRONT FCST TO MOVE EAST ACRS THE AREA TONIGHT. VIS SAT IMAGERY SHOWS EXPANDED AREA OF BROKEN CLEARING MOVING INTO WRN IND AT 19Z. SCTD THUNDERSTORMS ARE DEVELOPING IN MARGINALLY UNSTABLE WARM SECTOR BOTH ALONG THE WARM FRONT AND IN THE WARM SECTOR IMMEDIATELY AHEAD OF THE COLD FRONT. SOMEWHAT STRONG SFC HEATING COMMENCING ACRS ERN IL ALONG WITH INCREASING LOW LEVEL MOISTURE PER 50+ DEG DWPTS. MAIN FORECAST CHALLENGE TDY WL BE PCPN. MODELS REMAIN IN PRETTY GOOD AGREEMENT FOR TONIGHT AND TOMORROW SO THEREFORE WILL USE A BLEND. UPPER AIR ANALYSIS SHOWS CENTRAL IND LOCATED IN LEFT EXIT REGION OF CYCLONICALLY CURVED 250MB JET STREAK. EXPECTING SCTD SHOWERS AND THUNDERSTORMS TO DEVELOP ACRS AREA LATE THIS AFTERNOON AND INTO THE EVENING HOURS. COOL MID LEVEL TEMPS BELOW -20 DEG CELSIUS MOVING IN OVERTOP LOW LEVEL MOISTENING AND STEEPENING LAPSE RATES. AS 500MB SPEED MAX OF 100KTS CONTINUES TO MOVE TOWARD THE REGION...STRENGTHENING WIND FIELDS IN COMBO WITH MARGINALLY UNSTABLE ATMS SHOULD YIELD THE POSSIBILITY OF SOME ORGANIZED THUNDERSTORMS. THE STRONGEST AND MOST PERSISTENT STORMS ARE CAPABLE OF SEVERE WEATHER MAINLY IN THE FORM OF LARGE HAIL. THE STORMS SHOULD GRADUALLY MOVE TO THE EAST AND NORTH DURING THE EVENING HOURS. TEMPS TONIGHT SHOULD FALL INTO THE 30S. MODELS CONSISTENT IN SHOWING A LINGERING CHANCE OF PRECIP THURSDAY. MODEL SOUNDINGS INDICATING A POSSIBILITY OF SNOW SHOWERS MIXED WITH RAIN...ESPECIALLY IN THE NORTHERN AREAS THURSDAY. WHILE THE NEAR SURFACE LAYER SHOULD REMAIN ABOVE FREEZING...COLD AIR ALOFT WITH 850MB TEMPS AROUND -5 TO -6 DEG C WOULD BE SUPPORTIVE OF SUCH A SCENARIO. NOT EXPCTING MUCH RECOVERY IN TEMPS ON THURSDAY AS LOW CLOUDS REMAIN IN AREA AS INDIANA RECEIVES WRAP AROUND CLOUDS FROM DEPARTING SYSTEM. && .LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/... THURSDAY NIGHT...MODEL SOUNDINGS SHOW A MOIST LOW LEVEL ALONG WITH A WEAL INVERSION THROUGH MOST OF THE OVERNIGHT SO WILL GO A LITTLE MORE PESSIMISTIC WITH CLOUD COVER THURS NIGHT. THAT SAID WILL GO A DEGREE OR TWO WARMER WITH LOWS TO ACCOUNT FOR THE CLOUD COVER. NO PRECIP IS EXPECTED AS THE UPPER SYSTEM PULLS OFF TO THE NE BY LATE THURS NIGHT. FRIDAY...MODELS HAVE BEEN TRENDING SLOWER AND FARTHER SOUTH WITH THE UPCOMING WEEKEND SYSTEM. THIS WILL TRANSLATE INTO SLOWER TIMING FOR PRECIP AS WELL. HAVE CONFINED POPS TO THE VERY FAR SW CORNER OF THE CWA ON FRI MORNING. KEPT THE INDY METRO AREA AND NORTH DRY UNTIL AFTER 00Z. KEPT THE TERRE HAUTE AREA DRY UNTIL 21Z. AFTER 00Z LIKELY FOR THE MAJORITY OF THE CWA. AS THE SFC LOW MOVES NE FROM ARKANSAS TO TN/KY IT WEAKENS SOMEWHAT. 850-500MB FRONTOGENESIS ALSO WEAKENS. WOULD EXPECT THE HEAVIEST PRECIP TO FALL IN THE SOUTHERN CWA IN THE 00Z-12Z TIMEFRAME WITH LESSER AMOUNTS NORTH OF INTERSTATE 70. FOR TEMPS FRI NIGHT HAVE GONE WARMER WITH LOWS AS CLOUD COVER WILL PREVENT A SIGNIFICANT DROP IN TEMPS. SATURDAY...WITH THE FARTHER SOUTH SOLUTION OF THE ECMWF/GFS/NAM AND ENSEMBLES TEMPS MAY BE A LITTLE WARMER. THE NW 1/3 OF THE CWA MAY SEE SOME SNOW MIXED IN AS BUFKIT SOUNDINGS SHOW A POSSIBILITY. AT THIS TIME WILL LEAVE IT AS ALL RAIN AS ITS STILL FAR ENOUGH OUT IN TIME FOR EVEN A SLIGHT CHANGE TO KEEP PTYPE ALL RAIN THAT DAY. BY SATURDAY NIGHT THE SFC LOW WILL CONTINUE TO PULL OFF TO THE EAST AND HAVE TAPERED POPS OFF FROM WEST TO EAST. SUNDAY THROUGH WEDNESDAY...STRONG RIDGING SETS UP ACROSS THE MIDDLE OF THE COUNTRY THROUGH THIS TIME PD. TEMPS WILL FINALLY MODERATE CLOSER TO NORMAL TEMPS BY MON/TUES NEXT WEEK. && .AVIATION...DISCUSSION FOR 18Z TAFS. LOW PRESSURE WL MV THRU NW OF THE SITES DURING THE PD AND DRAG A CD FNT THRU INDIANA BY AROUND 0Z. MID LEVEL DRY SLOT WILL WORK ITS WAY INTO REGION THIS AFTERNOON ALONG WITH INCREASING LIFT ASSOC WITH UPPER LEVEL SYSTEM AND COLD FRONT. WIDELY SCATTERED SHOWERS ACROSS AREA WILL GIVE WAY TO SCATTERED THUNDERSTORMS IN THE 1930Z TO 0100Z PERIOD. HAVE GONE WITH VCTS TO CONVEY COVERAGE UNCERTAINTY AT THIS POINT AND MAY NEED TO MAKE AMENDMENTS FOR SPECIFIC TIMING. IFR CIGS AND VISBYS WILL OCCUR AHEAD OF THE SCATTERED THUNDERSTORMS EXPCT TO DVLP. EXPECTING A BRIEF WINDOW THIS EVENING OUTSIDE OF PRECIP TO HAVE MVFR CONDS AS LOW LEVEL CIGS MIX OUT AND VISBYS IMPROVE. IFR CONDS EXPTD TO RETURN AROUND 05Z FROM WRAP AROUND LOW LEVEL CLOUDS ASSOC WITH HIGHER RH AIR. && .IND WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM/AVIATION...SMITH/SH LONG TERM...SALLY
