A combination of a moist atmosphere, slow movement of convection and continued development of new convection resulted in heavy rainfall across much of northern Indiana. Radar estimated 2 to 5 inches of rain in many areas; however, localized flooding was reported in several areas and only isolated reports of flash flooding were received.

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 Sep 8, 12:13 PM EST, 3 hours 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 113 PM EDT SAT SEP 8 2007 .AVIATION...18Z TAFS HIGH END MVFR CIGS WILL LIKELY PREVAIL THIS AFTN AT FWA AS MOISTURE WILL CONTINUE TO OVERRIDE A SFC BDRY IN PLACE NEAR A LAF TO FDY LINE...JUST SOUTH OF THE FWA TERMINAL. CIGS NEAR 3KFT EXPECTED AT SBN THIS AFTERNOON...WILL CARRY A TEMPO BKN025 THROUGH 20Z TO ACCOUNT FOR MVFR CIGS NEARBY. THERE IS THE RISK FOR SCT CONVECTION THIS AFTN...BEST CHANCES BEING CLOSER TO THE FRONT AT FWA. WILL ADD A VCTS GROUP FOR FWA AND KEEP SBN DRY THROUGH 02Z. SHRA ACTIVITY IS EXPECTED LATE THIS EVENING INTO TONIGHT AS A CONVECTIVELY-INDUCED SHRTWV OVER SW MO WILL TRACK NEWD TOWARDS THE NRN OH VALLEY. THIS ALONG WITH A STRONG SHRTWV TRACKING THROUGH THE UPPER MIDWEST AND NRN LAKES WILL PROVIDE PLENTY OF DEEP LAYER MOISTURE AND LIFT FOR PRECIP TONIGHT. WILL ADD A -SHRA GROUP AFTER 03Z IN SBN AND SHRA IN FWA AFTER 02Z...ALONG WITH VCTS MENTION AT FWA WITH THE FRONT NEAR. SOME ELEVATED CONVECTION IS POSSIBLE IN SBN BUT WILL LEAVE THUNDER MENTION OUT FOR NOW. UPSTREAM OBS AND FCST SOUNDINGS INDICATE IFR AND LOW-END MVFR CIGS FOR TONIGHT INTO SUNDAY MORNING. WINDS SHOULD REMAIN BLO 10KTS THROUGH THE TAF PERIOD. && PREV DISCUSSION... SHORT TERM... MAIN ISSUE FOR SHORT TERM PERIOD WILL BE POSITION OF FRONTAL BOUNDARY. METARS SHOWING BOUNDARY PUSHING SE INTO CENTRAL IN EARLY THIS MORNING. EXPECT BOUNDARY TO LINGER TO THE S OF CWA AS ITS ASSOCIATED SFC LOW STRENGTHENS AND MOVES NE OVER SRN CANADA. A SHORT/WV WILL APPROACH FROM THE SW TODAY TRACKING OVER SRN IN INTO CENTRAL OH. THIS WAVE WILL CAUSE THE FRONTAL ZONE TO PUSH BACK NORTH INTO LOWER MI BY TONIGHT PROVIDING A TRIGGER FOR CONVECTION. WITH LIMITED INSTABILITY CAUSED BY CLOUD COVER AND ADJACENT STABLE AIR MASS JUST NORTH OF THE FRONT...EXPECT ANY THUNDERSTORMS TO REMAIN BLO SEVERE. WITH TRACK OF SHRT/WV THROUGH CENTRAL OH AIDED BY 30-35KT H85 LLJ TONIGHT...BELIEVE SE CWA WILL HAVE THE BEST SHOT FOR CONVECTIVE ACTIVITY. TEMPS EXPECTED TO BE PROBLEMATIC ONCE AGAIN WITH SKIES ACROSS THE NORTH LIKELY HAVING A PERIOD OF PARTLY SUNNY VS THE SOUTH WHICH MAY REMAIN MOSTLY CLOUDY MUCH OF THE DAY. EXPECTING HIGHS IN THE MID TO UPPER 70S ACROSS THE AREA. OVERNIGHT LOWS WILL THEN DROP OFF INTO THE LOW TO MID 60S AS MSTR INCREASING AGAIN AND EXPECTED RAINFALL ESPECIALLY SE. LONG TERM... WATER VAPOR IMAGERY CONTG TO SHOW SERIES OF SHRTWVS ALONG SRN PORTION OF BROAD MEAN TROF OVER CANADA AND TOPPING RIDGE IN ERN PACIFIC. STRONG SHRTWV WHICH AFFECTED OUR AREA TODAY WAS MOVG INTO THE LWR GRTLKS AND OH VALLEY WITH SUB-TROPICAL MOISTURE PLUME CONTG TO STREAM NE-ENE AHEAD OF IT. SFC CDFNT ASSOCIATED WITH THIS SHRTWV HAS BECOME PARALLEL TO MID LEVEL FLOW AND THUS SHOULD MAKE LITTLE ADDITIONAL SEWD PROGRESS. NEXT SHRTWV OF INTEREST OVER MT THIS MORNING AND IS FCST TO MOVE TO NRN MN BY 12Z SUNDAY. BACKING FLOW AHEAD OF THIS SYSTEM SHOULD RESULT IN SOME OVERRUNNING SHOWERS/TSTMS NORTH OF THE STALLED E-W BOUNDARY OVER CENTRAL INDIANA, WHILE SFC CDFNT ASSOCIATED WITH THIS SYSTEM SHOULD MOVE ACROSS THE CWA SUNDAY. NAM DEPICTION OF THESE EVENTS APPEARS MORE REASONABLE THAN GFS WHICH APPEARS TO BE TOO DEEP WITH LOW ALONG OLD BOUNDARY... PRBLY DUE TO CONVECTIVE FEEDBACK AND TOO WK WITH NRN STREAM SYSTEM... PSBLY AS A RESULT OF OVERDEVELOPING SRN STREAM SYSTEM LOW. NAM SOLUTION SUPPORTS GOING CHC OF TSTMS ACROSS ALL BUT FAR NW PORTION OF THE CWA THROUGH THE DAY SUNDAY WITH HIGHEST POPS SE CLOSEST TO STALLED OLD BOUNDARY AND WHERE FROPA WILL OCCUR LATEST IN THE DAY ALLOWING FOR BETTER DESTABILIZATION. HIGH PRESSURE RIDGE SHOULD BUILD INTO THE WRN GRTLKS REGION BEHIND THIS FRONT SUNDAY NIGHT PROVIDING FAIR WX. NEXT SHRTWV OF INTEREST OVER BRITISH COLUMBIA THIS MORNING IS EXPECTED TO DIG SE TO THE GRTLKS MON/MON NGT. ALTHOUGH THIS SYSTEM MAY PROVIDE SUFFICIENT MID LEVEL LIFT IN OUR AREA TO SUPPORT A FEW SHOWERS, APPEARS AIRMASS WILL BE STABLE ENOUGH BY THAT TIME TO PREVENT TSTMS AND HAVE THUS REMOVED MENTION FOR THIS PERIOD.
