An upper low was located over the northern Great Lakes. While no distinct fronts or waves were noted, enough instability and shear was in place across the region to allow for isolated thunderstorm development.

The episode as NWS IWX wrote it up.
An upper low was located over the northern Great Lakes. While no distinct fronts or waves were noted, enough instability and shear was in place across the region to allow for isolated thunderstorm development. The majority of these storms produced brief, heavy rainfall and gusty winds. Isolated wind damage was reported in Jay County with some flash flooding across portions of Wabash counties where storms continued to train over the same areas for a few hours.
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 2, 2:23 PM EST, 1 hour 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 323 PM EDT TUE JUL 2 2013 .SYNOPSIS... ISSUED AT 202 PM EDT TUE JUL 2 2013 LOW PRESSURE OVER THE OHIO VALLEY IS EXPECTED TO MOVE SLOWLY NORTH OVER THE NEXT COUPLE OF DAYS. THIS SYSTEM WILL CAUSE SHOWERS AND A FEW THUNDERSTORMS IN OUR AREA THIS EVENING... WITH SHOWERS BECOMING LESS NUMEROUS ON WEDNESDAY. TEMPERATURES WILL BE ON THE COOL SIDE FOR MID-SUMMER WITH HIGHS ONLY EXPECTED IN THE 70S TODAY... WARMING SLIGHTLY ON WEDNESDAY. A STRONG HIGH PRESSURE SYSTEM CENTERED OFF THE MID ATLANTIC COAST WILL INFLUENCE OUR WEATHER LATER THIS WEEK... CAUSING A RETURN TO SOUTHERLY WIND FLOW WHICH WILL BRING WARMER AND MORE HUMID AIR INTO THE AREA. THIS MAY ALSO RESULT IN A FEW AFTERNOON AND EVENING THUNDERSTORMS IN OUR AREA LATE THIS WEEK. && .SHORT TERM...(THIS EVENING THROUGH WEDNESDAY) ISSUED AT 321 PM EDT TUE JUL 2 2013 CLUSTER OF MORNING SHOWERS ASSOCIATED WITH TROUGH AXIS HAS SHIFTED TO THE NW CORNER OF THE CWA DUE TO STRENGTHENING OF HIGH PRESSURE ALONG THE ATLANTIC COAST. DIURNAL HEATING IN CONJUNCTION WITH NORTHWARD SHIFT OF OHIO VALLEY LOW HAS RENEWED THE POSSIBILITY FOR SCATTERED SHOWER AND THUNDERSTORM DEVELOPMENT THIS AFTERNOON. A FEW SHOWERS ARE BEGINNING TO POP UP ON REGIONAL RADAR ALONG THE SURFACE BOUNDARY/TEMPERATURE GRADIENT DRAPED ACROSS CENTRAL INDIANA. STRONGER 0-6KM SHEAR OF 30+ KTS IS SPILLING INTO THE EASTERN PORTIONS OF THE CWA WITH THE WESTERN SURGE OF THE ATLANTIC HIGH PRESSURE RIDGE. CONTINUED CLOUD COVER WILL LIMIT HIGH TEMPERATURES TO THE LOW TO MID 70S THIS AFTERNOON AND HAS KEPT INSTABILITY FROM BECOMING OVERLY ROBUST...BUT WEAK TO MODERATE INSTABILITY COMBINED WITH SUFFICIENT SHEAR COULD RESULT IN THE DEVELOPMENT OF A STRONG TO SEVERE CELL IN THE SOUTHEASTERN PORTION OF THE CWA IN THE VICINITY OF A SURFACE BOUNDARY LATER THIS AFTERNOON. SHOWERS AND THUNDERSTORMS COULD CONTINUE INTO THE EARLY PART OF THE OVERNIGHT HOURS AS MODERATE ISENTROPIC LIFT WILL BE POSSIBLE TO THE NORTHEAST OF THE SURFACE LOW...WITH THE GREATEST AREA OF ASCENT OVER THE NORTHWEST CORNER OF THE CWA. BY THE EARLY MORNING HOURS WEDNESDAY LOW TEMPERATURES ARE EXPECTED TO DROP TO NEAR DEWPOINT LEVELS IN THE LOW TO MID 60S CREATING THE POTENTIAL FOR PATCHY FOG DEVELOPMENT. CURRENTLY THERE IS A SLIGHT CHANCE OF SHOWERS AND STORMS LINGERING THROUGH WEDNESDAY MORNING...BUT BEST CHANCE FOR PRECIP APPEARS TO BE TOWARDS THE PEAK HEATING HOURS WHEN DIURNALLY DRIVEN STORM DEVELOPMENT WILL BE POSSIBLE. STRONGER SOUTHERLY FLOW WILL ALLOW WARMER AIR TO ADVECT INTO THE REGION TOMORROW...WITH HIGHS TOPPING OUT IN THE UPPER 70S TO LOW 80S. && .LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY) ISSUED AT 321 PM EDT TUE JUL 2 2013 MODELS IN REASONABLE AGREEMENT EARLY ON WITH LARGE SCALE FEATURES BUT CONTINUE TO DIFFER IN TIMING AND PLACEMENT OF SMALLER SCALE DETAILS AND RESULTING SENSIBLE WEATHER. BLOCKING UPPER LEVEL PATTERN WILL PERSIST INTO THE BEGINNING OF THE FORECAST PERIOD. CLOSED LOW OVER THE MID MS VALLY WILL OPEN UP AND SLOWLY RETROGRADE IN RESPONSE TO BERMUDA HIGH OVER THE ATLANTIC STRENGTHENING AND EXPANDING WESTWARD. WHILE THIS WILL SHIFT THE FORCING ASSOCIATED WITH THE UPPER LOW WEST OF OUR AREA...IT WILL HAVE THE UNFORTUNATE SIDE EFFECT OF ALSO SHIFTING THE FLOW OF GULF MOISTURE CURRENTLY STREAMING UP ALONG THE EASTERN SEABOARD WESTWARD TOWARD OUR REGION. THIS IS WHERE MODELS DIVERGE IN TIMING AND PLACEMENT AND MAKE PINPOINTING OPPORTUNITIES FOR A DRY FCST PROBLEMATIC. TO VARYING DEGREES MODELS INDICATING FLOW OF DEEP LAYER MOISTURE FROM THE GULF WORKING ITS WAY UP INTO THE REGION AS PATTERN RETROGRADES. BUT LACKING ANY DISCERNIBLE SFC FEATURE TO AID IN FOCUSING PRECIP DEVELOPMENT LEAVES MUCH UNCERTAINTY AND LITTLE MODEL AGREEMENT IN TIMING AND PLACEMENT. WILL THEREFORE RELUCTANTLY LEAVE AT LEAST SLIGHT CHANCE IN FCST UNTIL MORE DEFINABLE WINDOW OF DRY FCST PRESENTS ITSELF. NORTHERN STREAM ZONAL FLOW ATTEMPTS TO WORK DOWN INTO THE REGION BY THE END OF THE FCST PERIOD AND WILL HAVE A SFC FRONTAL BOUNDARY APPROACHING THE AREA AND WITH IT A BETTER CHANCE FOR SHOWERS AND THUNDERSTORMS. INCREASING SOUTHERLY FLOW WILL BRING MORE HUMID CONDITIONS GOING INTO THE WEEKEND AND WILL HAVE LOWS IN THE U60S TO NEAR 70 WHILE HIGHS WILL BE GETTING BACK CLOSE TO NORMAL. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z WEDNESDAY MORNING) ISSUED AT 150 PM EDT TUE JUL 2 2013 A FEW SHOWERS ASSOCIATED A LOW PRESSURE SYSTEM CENTERED OVER THE OHIO VALLEY ARE MAKING THEIR WAY OUT OF THE REGION THIS AFTERNOON. EXPECT CIGS TO RAISE TO MVFR LEVELS LATER TODAY AS DECK OF LOW CLOUDS PUSHES OFF TO THE NW. A FEW SHRA AND TS COULD REDEVELOP THIS EVENING WITH HEATING INCREASING THROUGH BREAKS CLOUD COVER. FOG COULD DEVELOP BY TOMORROW AS TEMPERATURES DECREASE WITHIN A MOIST BOUNDARY LAYER...CREATING OCCASIONAL IFR VISIBILITIES AROUND 06Z WEDNESDAY. VISIBILITIES SHOULD IMPROVE BY 12Z TOMORROW WITH CIGS REMAINING WITHIN THE MVFR CATEGORY. WINDS ARE EXPECTED TO LIGHTEN THROUGH THE EVENING AND TURN MORE SOUTHERLY BY WEDNESDAY AFTERNOON. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
