an unstable atmosphere and a upper level disturbance all set the stage for scattered to numerous thunderstorms across the area. While the majority remained below severe limits, a few severe events were reported.

The episode as NWS IWX wrote it up.
Several weak boundaries across northern Indiana...an unstable atmosphere and a upper level disturbance all set the stage for scattered to numerous thunderstorms across the area. While the majority remained below severe limits, a few severe events were reported. In addition, one of the stationary boundries from Allen county Indiana northeast to the Michigan/Indiana state line, was the focus for the redevelopment of convection and resulted in some areas of flooding.
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 Jun 3, 1:00 PM EST, 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 200 PM EDT SUN JUN 3 2007 .AVIATION... SEVERAL N-S ORIENTED LINES OF TSTMS HAVE DEVELOPED OVER NRN INDIANA EARLY THIS AFTN. ONE LINE CURRENTLY EXTENDING THROUGH FWA AND CONTG TO DVLP TO THE SOUTH SHOULD CONT TO AFFECT THE TERMINAL FOR THE NEXT 1-2HRS. VISIBLE STLT INDICATES A SMALL CLEAR SLOT WEST OF SBN WHICH SHOULD ALLOW FOR DESTABILIZATION FOR FURTHER DEVELOPMENT WHICH WILL AFFECT SBN THIS AFTN. CDFNT OVER ERN IL SHOULD MOVE ACROSS NRN INDIANA THIS EVE, SHIFTING WINDS TO WEST AND DECREASING CONVECTION. SECONDARY CDFNT WILL DROP SE ACROSS THE AREA ON MONDAY RESULTING IN WIND SHIFT TO NW WITH MORE SHOWERS AND TSTMS EXPECTED AS THIS MOVES THROUGH. THIS SHOULD TAKE PLACE VERY LATE IN THE TAF PERIOD OR MORE LIKELY JUST BEYOND, SO NO MENTION IN TAFS ATTM. && .SHORT TERM... TODAY AND TONIGHT MAIN FORECAST CHALLENGES WILL BE FORECAST HIGH TEMPS TODAY AND INTENSITY OF CONVECTION TODAY. OTHERWISE...FORECAST PRETTY MUCH ON TRACK PRECIP WISE...GIVEN AMPLE FORCING AVAILABLE FROM H5 VORTEX. CURRENT ANALYSIS REVEALS 20 TO 30 KNOT LL JET IN PLACE ACROSS WESTERN IN/EASTERN IL PER VWP/PROFILER/RUC ANALYSIS. THIS FEATURE COUPLED WITH RESIDUAL MID LEVEL WAVE HAS ALLOWED SHOWER/THUNDERSTORM DEVELOPMENT. WEAK INSTABILITY HAS LIMITED CONVECTIVE INTENSITY...WITH MAJORITY OF PRECIP IN THE FORM OF LIGHT TO MODERATE SHOWERS. THIS AREA OF PRECIP IS PROGGED TO CONTINUE NORTHEASTWARD INTO WESTERN ZONES THROUGH LATE MORNING. SHOULD SEE A DIMINISHING TREND AS LL JET WEAKENS AFTER SUNRISE. OTHERWISE...TEMPS WERE MAINLY IN THE UPPER 60S ACROSS THE FA WITH LIGHT TO CALM WINDS. PRECIP FOCUS WILL SHIFT TO SFC COLD FRONT THIS AFTERNOON. WRF AND GFS BOTH INDICATE GOOD CONVERGENCE ALONG AND AHEAD OF COLD FRONT THIS AFTERNOON. MEANWHILE BROAD LIFT FROM H5 VORTEX WILL INCREASE POTENTIAL INSTABILITY WITH AMPLE MID LEVEL DRY IN PLACE UPSTREAM GIVEN 00Z DVN SOUNDING. BIG QUESTION MARK WILL BE HOW MUCH DAYTIME HEATING WILL BE SEEN ACROSS FA BEFORE GOOD DYNAMICS FALL IN PLACE. SUNSHINE MAY BE LACKING TODAY DUE TO RESIDUAL CLOUD COVER FROM CURRENT UPSTREAM CONVECTION. THIS WILL ALSO HAVE AN IMPACT ON HIGHS TODAY. HAVE TRENDED TOWARD COOLER SOLUTION IN FORECAST...GIVEN WIDESPREAD CLOUD COVER IN PLACE. HOWEVER...IF SUNSHINE DOES BREAK OUT...SFC BASED CAPE VALUES WOULD EASILY CLIMB TO AOR 1500 J/KG. DEEP SHEAR WILL ALSO BE ON THE INCREASE AS ASSOCIATED UPPER JET STREAK ADVECTS INTO THE REGION...PRODUCING DEEP SHEAR VALUES AROUND 30-35 KNOTS...ESPECIALLY IN WESTERN ZONES. BOTTOM LINE...IF GOOD HEATING DOES OCCUR...SEVERE THREAT WOULD BE ELEVATED. HOWEVER...NOT THINKING ANYTHING WIDESPREAD. MAIN THREATS WOULD BE DAMAGING WIND AND LARGE HAIL. AGAIN HIGHS TODAY WILL BE STRONGLY DEPENDENT ON CLOUD COVER. CURRENT TEMPS IN GRIDS REFLECT PARTIAL CLEARING. TEMPS COULD EASILY SWAY 5-7 DEGREES EITHER WAY DEPENDING ON AMOUNT OF ISOLATION. RAIN SHOWER/ISOLATED THUNDER CHANCES WILL CONTINUE TONIGHT...ESPECIALLY IN NORTHERN PORTIONS OF FA. DRY SLOT WITH SUBSIDENCE BEHIND LEAD WAVE MAY CLEAR OUT SOUTHERN ZONES...HENCE HAVE LEFT LOWER POPS THERE. COOLER AIR WILL MOVE INTO THE FA TONIGHT. AMPLE LL MOISTURE IN PLACE WITH EXPECTED RAIN COMBINED WITH THIS COOLER AIR MAY LEAD TO AREAS OF FOG. HAVE NOT WORDED IN FORECAST YET...AS THERE IS QUESTIONS ON AMOUNT OF CLOUD COVER. .LONG TERM... MONDAY THROUGH SATURDAY UPPER LOW STILL EXPECTED TO DRIFT INTO OUR AREA BY MONDAY BEFORE OPENING UP AND LIFTING OUT ON TUESDAY. DECENT MID LEVEL LAPSE RATES UNDER CIRCULATION MONDAY WITH LOW LEVEL MOISTURE AND WEAK SHORT WAVES SHOULD LEAD TO SHOWER AND THUNDERSTORM DEVELOPMENT DURING THE DAY. BUMPED POPS INTO LIKELY CATEGORY. MODELS LINGER MOISTURE WITH SURFACE FRONT INTO MONDAY NIGHT SO HIGH CHANCE POPS THROUGH THIS PERIOD. LOW BEGINS TO EXIT ON TUE WITH SOME LINGERING MOISTURE ON BACK SIDE. PREVIOUS SHIFT ADDED POPS FOR TUE SO WILL CONTINUE THOUGH DRYING WORKING IN QUICKLY. MODELS MAY STILL BE A TAD FAST LIFTING LOW OUT. TEMPERATURES COOLER THROUGH THIS PERIOD AS WELL. CUT TEMPS SEVERAL DEGREES ON MONDAY...ESPECIALLY NORTHWEST WITH UPPER LOW OVER AREA AND FLOW INCREASING OFF OF COOLER LAKE MICHIGAN. NAM12 2M TEMPS STRUGGLE TO EVEN GET OUT OF THE 50S. HAVE DROPPED TO MID 60S CLOSER TO COOLER MOS FOR NOW. WILL ALSO MENTION RIP CURRENTS FOR LAKE MICHIGAN IN HWO FOR THIS PERIOD WITH RATHER STRONG NORTHWEST WINDS EXPECTED TO DEVELOP AND INCREASING WAVES. HIGH PRESSURE SETTLES OVER THE AREA FOR WED BEFORE RETURN FLOW QUICKLY SETS UP AND WARM FRONT MOVES THROUGH WED NIGHT. KEPT THIS PERIOD DRY FOR NOW AS MODELS INDICATE LIMITED MOISTURE. HOWEVER...WITH SUCH A STRONG FRONT AND TIGHTENING BAROCLINIC ZONE...WOULD EXPECT SOME PCPN TO DEVELOP ON NOSE OF INCREASING LOW LEVEL JET. BEST FOCUS CURRENTLY LOOKS TO BE TO OUR NORTHWEST BUT WILL MONITOR. THURSDAY STILL LOOKING VERY WARM AND CONTINUED TO STAY ABOVE MEX MOS AND RAISED TEMPS A FEW MORE DEGREES. ECMWF VERY WARM WITH +20C AT 850MB. HAVE DOUBTS AS TO THUNDERSTORM CHANCES GIVEN VERY WARM AIR ALOFT AND LACK OF TRIGGER TIL LATER IN THE DAY OR THU NIGHT WITH POSSIBLE APPROACH OF COLD FRONT. MODELS VARY IN TIMING AND GENERAL SOLUTIONS SO NO CHANGES AT THIS TIME. UNCERTAINTY CONTINUES REMAINDER OF EXTENDED WITH MODELS DIFFERING ON FRONTAL POSITION AND MOVEMENT SO NO CHANGES. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
