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
Detroit, MI (KDTX), launched 00:00Z, 0.4 hours before the alert went out and 173 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 30, 3:46 PM EDT, 4 hours 37 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 246 PM EST WED APR 30 2003 FORECAST CHALLENGE WILL BE WARM FRONT LOCATION... CURRENTLY A WARM FRONT EXTENDS FROM LIMA OHIO TO PERU INDIANA TO PEORIA ILLINOIS. PROGRESS HAS BEEN SLOWLY NORTH. MCS THAT MOVED ACROSS NORTHERN INDIANA...SOUTHERN MICHIGAN AND NORTHWEST OHIO THIS MORNING HAS RETARDED NORTHWARD PROGRESS. TEMPERATURES SOUTH OF THE FRONT HAVE MOVED INTO THE UPPER 60S AND LOWER 70S BY NOON. THIS MORNING UPPER AIR CHARTS SHOW A 30KT 850MB JET STREAK OVER OKLAHOMA TO NORTHWEST ILLINOIS IS FEEDING CONVECTION OVER EASTERN IOWA AND NORTHWEST ILLINOIS. THIS AREA IS IN BETWEEN TWO 300MB JET STREAKS OUTTING IT IN AN AREA OF GOOD LIFT. THUNDERSTORM DEVELOPMENT IS QUITE LIKELY AND A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED FOR ALL OF OUR NORTHERN INDIANA COUNTIES UNTIL 6 PM EST. MODELS ARE NOT HANDLING THE MOVEMENT OF THE WARM FRONT WELL SO WILL SLOW ITS MOVEMENT. STILL EXPECT IT TO MOVE NORTH OF THE FORECAST AREA...BUT LATER THAN CURRENTLY THOUGHT SO WILL LOWER MIN TEMPERATURES OVER EXTREME SOUTHERN MICHIGAN AND FAR NORTHERN INDIANA. WILL RAISE LOW TEMPS A COUPLE OF DEGREES FOR THE SOUTHERN COUNTIES. CHANCE OF RAIN CONTINUES TO LOOK GOOD IN THAT THE FRONTAL BOUNDARY WILL NOT MOVE AS FAR NORTH AS INDICATED EARLIER. WILL KEEP LIKELY POPS OVERNIGHT NORTH AND CHANCE POPS SOUTH. ALL MODELS HAVE COLD FRONT SLOWLY MOVING THROUGH THURSDAY. COLD FRONT MOVEMENT SEEM REASONABLE SINCE THE SHORT WAVE TROF ASSOCIATED WITH THE SYSTEM SEEMS TO BE WEAKENING WHICH WOULD MAKE IT MORE DIFFICULT FOR THE FRONT TO MOVE THROUGH. CURRENT FORECAST STILL LOOKS GOOD FOR THURSDAY EXCEPT FOR THE NORTH WHERE MAXIMUM TEMPERATURE ARE TOO HIGH...WILL LOWER THEM A CATEGORY. FRONT WILL SLOWLY MOVE ACROSS THE AREA THURSDAY AFTERNOON. SHOWERS AND POSSIBLE THUNDERSTORMS CONTINUE CAN BE EXPECTED OVER THE AREA THURDAY AND SHOWERS THURSDAY NIGHT AND INTO FRIDAY AS THE FRONT HAS TROUBLE MOVING EAST. WILL KEEP LIKELY POPS ACROSS THE ENTIRE AREA THURSDAY AND CHANCE POPS THURSDAY NIGHT AND FRIDAY. FRONT FINALLY MOVES FAR ENOUGH EAST BY SATURDAY SO WILL KEEP SATURDAY DRY. FORECAST DISCUSSION FOR SATURDAY NIGHT THROUGH WEDNESDAY... SATURDAY NIGHT WILL START OUT WITH HIGH PRESSURE OVER THE AREA. THEN SUNDAY NIGHT A LOW PRESSURE SYSTEM WILL BEGIN TO MOVE INTO OUR COUNTY WARNING AREA (CWA). THEN MONDAY INTO EARLY TUESDAY THIS SYSTEM WILL BE MOVING THROUGH THE CWA WITH AN AREA OF HIGH PRESSURE BEGINNING TO MOVE IN TUESDAY NIGHT AND THIS WILL BE OVER THE CWA ON WEDNESDAY. LOOKS LIKE THE CHANCE FOR RAIN WILL START EARLY MONDAY MORNING. THE GEM HAS LOW CENTER SLIGHTLY NORTH OF MRFS POSITION FOR MONDAY...GFS LINES UP THE LOW MONDAY MORNING WITH AVN/MRF OVER IOWA. ECMWF HOLDS LOW MORE WESTERLY THAN MRF ON TUE. OVERALL IT APPEARS THAT THE GEM IS SLOWER WITH LOW THAN MRF/AVN. LOOKS LIKE THERE IS A BETTER CHANCE FOR RAIN/T-STORMS ON MONDAY THAN TUESDAY. CHANGED THESE TWO DAYS TO REFLECT THIS. TEMPERATURES FOR THE MOST PART LOOKED OK. .IWX... IN...NONE. MI...NONE. OH...NONE. GREG LAMBERTY
