The episode as NWS IWX wrote it up.
A complex of thunderstorms bowed out across eastern Illinois and continued rapidly east and then southeast into portions of northern Indiana. Wind damage was reported in some locations of west central Indiana.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Northern Indiana wrote its last area forecast discussion before the first event at Jul 21, 6:53 AM EST, 2 hours 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 753 AM EDT MON JUL 21 2008 .AVIATION/UPDATE... IFR/LIFR CONDITIONS AT BOTH SITES EXPECTED TO QUICKLY IMPROVE OVER THE NEXT HOUR OR 2 AS STG MIXING GETS UNDERWAY...SO JUST A BRIEF MENTION IN TAFS. MAIN FOCUS THEN TURNS TO CONVECTIVE POTENTIAL TODAY. 2 AREAS OF STORMS NOW MOVING ACROSS PORTIONS OF CTRL AND NORTHERN ILLINOIS. FIRST CLUSTER IS AFFECTING THE BLOOMINGTON AND CHAMPAIGN AREAS AND WILL CONTINUE DROPPING SE AND POSES NO THREAT TO US. 2ND LARGER COMPLEX NOW MOVING THROUGH THE PEORIA AREA WILL NEED TO BE MONITORED. OVERALL TREND BASED ON THETA E GRADIENT SHOWS THIS AREA SHOULD BEGIN TO TURN MORE SE WITH TIME AND HOPEFULLY REMAIN AWAY FROM BOTH TAF SITES. WILL HANDLE WITH VCTS FOR NOW. CONVECTION CHANCES AHEAD OF THE SLOWLY MOVING COLD FRONT QUESTIONABLE AT THIS POINT WITH APPROACHING MCS SO WILL LEAVE OUT ANYTHING FOR NOW. && .PREV DISCUSSION... /ISSUED 358 AM EDT MON JUL 21 2008/ SHORT TERM... MONDAY THROUGH TUESDAY NIGHT... LATEST SFC ANALYSIS HAS FRONTAL WAVE OVER NORTHERN LOWER MICHIGAN WITH QUASI-STATIONARY BOUNDARY EXTENDING BACK THROUGH SOUTH CENTRAL WISCONSIN AND CENTRAL IOWA. LATEST IN A SERIES OF MCS MAKING ITS WAY THROUGH IOWA ATTM. THICKNESS AND THETAE PATTERN STILL INDICATING THIS SYSTEM WILL SINK SOUTH AS IT PROPAGATES TOWARD OUR AREA THIS MORNING...GIVING OUR SW CWA BEST CHANCE OF SEEING PRECIP. SFC FRONT EXPECTED TO SLOWING DRIFT SOUTH TODAY AND WILL SEE SOME UPPER SUPPORT AS SHORT WAVE MOVING THROUGH SOUTH DAKOTA ATTM WILL PUSH INTO THE GREAT LAKES REGION LATER TODAY. DESTABILIZATION OF AIRMASS AHEAD WILL BE KEY TO TRIGGER ANY NEW CONVECTION GIVEN LACK OF FORCING ALONG THE FRONT ITSELF. THIS IS FURTHER COMPLICATED BY ONGOING MCS...AS ANY OUTFLOW BOUNDARIES IT GENERATES MAY RE-ORIENT FOCUS FOR NEW CONVECTION THIS AFTERNOON. WILL KEEP ENTIRE CWA IN CHANCE POPS WITH HIGHER VALUES IN SOUTHERN TIER. COOLER AND LESS HUMID CONDITIONS EXPECTED TUESDAY AND TUESDAY NIGHT AS HIGH PRESSURE SETTLES INTO THE GREAT LAKES REGION. WENT CLOSE TO MOS GUIDANCE FOR HIGHS TODAY AS SOUTHERN CWA COULD SEE U80S AHEAD OF APPROACHING FRONT WITH MID 80S ELSEWHERE. BEH WAS LIMITED TO MID 70S YESTERDAY AND WITH NORTHERLY FLOW BEHIND FRONT SHOULD ONCE AGAIN SEE A LAKE INFLUENCE THERE. LONG TERM... WEDNESDAY THROUGH SUNDAY MEAN SYNOPTIC PATTERN THROUGH THE PERIOD WILL FEATURE TROUGHING OVER THE NE PACIFIC AND OVER ONTARIO/QUEBEC...WITH RIDGING OVER THE ROCKIES AND PLAIN STATES. LOCALLY THE REGION WILL BE IN A ZONE FAVORED FOR SFC RIDGING. ANOMALOUSLY DEEP UPPER LOW PRESSURE OVER THE EASTERN GREAT LAKES WILL SUPPORT NE FLOW INTO THE REGION AT THE SFC...BRINGING AT OR SLIGHTLY BELOW NORMAL TEMPERATURES WITH BELOW NORMAL RAINFALL. FORECAST MODELS AND MEAN ENSEMBLES SHARE RELATIVELY GOOD AGREEMENT THROUGH THE PERIOD...SAVE SOME DIFFERENCES ON TIMING OF A SW TROUGH IN THE FRI-SAT TIME PERIOD. THE ONLY OTHER CONCERN IS THE GENERAL BIAS THAT DETERMINISTIC MODELS SHARE WRT RIDGE BREAKDOWN IN CENTRAL CANADA AS WELL AS THE QUICK DEPARTURE OF THE SE CANADIAN UPPER TROUGH...ESPECIALLY GIVEN THE AMPLITUDE OF THE PROGGED RIDGE WHICH COULD VERY WELL SUPPORT A BLOCKING PATTERN. HENCE...HAVE FAVORED THE MEAN GFS ENSEMBLE SOLUTION WHICH PREFERS AN ANCHORED RIDGE OVER THE ROCKIES...WITH ONGOING MEAN TROUGHING ACROSS THE EASTERN THIRD OF THE CONUS. THIS BASICALLY SUPPORTS A RELATIVELY TRANQUIL PERIOD WITH MEAN SFC RIDGING OVER THE LOCAL REGION...AS THE EASTERN UPPER TROUGH CONTINUES TO BE REINFORCED BY SEVERAL DISTURBANCES IN NW FLOW...THE AFFECTS OF WHICH WILL LIKELY STAY WELL NE OF THE FA. THE ONLY SYSTEM TO HAVE ANY IMPACTS IN THE PRECIP DEPARTMENT WILL BE THE FRIDAY-SATURDAY SYSTEM...WHICH THE 00Z 21 GFS NOW BRINGS IN A DAY LATER. HOWEVER...EVEN THIS SYSTEM LOOKS UNIMPRESSIVE AT THIS TIME WITH THE MAIN LOBE OF PVA PASSING WELL NE OF THE FA. WILL LEAVE PRECIP CHANCES RIDE ON FRIDAY FOR NOW UNTIL BETTER SIGNALS ARE ESTABLISHED. OTHERWISE...HAVE LOWERED TEMPS ONE OR TWO DEGREES THROUGH MOST OF THE PERIOD GIVEN H85 TEMPS FALLING TO 11C WED. THIS INCLUDES AREAS NEAR LK MI WHERE A GENERALLY WEAK SFC PRESSURE GRADIENT WILL SUPPORT THE LAKE BREEZE CIRCULATION...ACTING TO INCREASE RIP CURRENT THREATS. ALSO LOWERED SFC DEWPOINTS GIVEN DRY NE FLOW/DEEP MIXING/AND DEPLETING SFC SOIL MOISTURE. WOULD NOT BE SURPRISED TO SEE DEWPOINTS FALL INTO THE UPPER 40S ACROSS THE NORTH BY MID WEEK...DEFINITELY ATYPICAL OF JULY IN THIS REGION. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE.
