The episode as NWS IWX wrote it up.
A cluster of thunderstorms developed southwest of Chicago during the mid evening hours and moved rapidly east, taking on a bowing structure as it entered northwestern Indiana. Wind damage was reported across La Porte and St. Joseph counties before the line rapidly began weakening as it encountered a more stable air mass.
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 May 28, 5:25 PM CST, 3 hours 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 725 PM EDT TUE MAY 28 2013 .SYNOPSIS... ISSUED AT 715 PM EDT TUE MAY 28 2013 SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE TONIGHT INTO EARLY WEDNESDAY MORNING AS SEVERAL DISTURBANCES MOVE THROUGH THE REGION. A FEW OF THESE STORMS COULD BECOME STRONG TO SEVERE AS WELL AS PRODUCE SOME LOCALLY HEAVY RAINFALL. RAIN CHANCES ARE EXPECTED TO DECREASE DURING THE DAY ON WEDNESDAY AS HIGH PRESSURE BUILDS INTO THE OHIO VALLEY...MAKING FOR PARTLY CLOUDY SKIES AND WARMER TEMPERATURES ON WEDNESDAY INTO THURSDAY. && .SHORT TERM...(THIS EVENING THROUGH WEDNESDAY) ISSUED AT 343 PM EDT TUE MAY 28 2013 CONVECTION ASSOCIATED WITH EARLIER PASSING MCV IS NOW WELL NORTHEAST OF HERE. ATMOSPHERE JUST NOW STARTING TO DESTABILIZE WITH A FEW PEAKS OF SUN AND PERSISTENT SW FLOW PUSHING SURFACE TEMPS INTO THE MID/UPPER 70S AND DEWPOINTS INTO THE MID/UPPER 60S. HOWEVER...WITH A LACK OF FOCUSED LIFTING MECHANISM...CONVECTION HAS BEEN RATHER SPORADIC AND MAINLY TIED TO AREA OF SUBTLE LOW LEVEL CONVERGENCE. EXPECT THIS WILL CONTINUE TO BE THE CASE FOR THE NEXT FEW HOURS. LATEST VAD WIND PROFILE SHOWS A RESPECTABLE SPEED MAX ALOFT BUT SPC/RAP MESOANALYSIS SHOWS INSTABILITY STRUGGLING TO BUILD OVER OUR CWA AND SEVERE THREAT WILL THEREFORE REMAIN ISOLATED. ADDITIONAL CONVECTION EXPECTED OVER THE REGION LATER TONIGHT THOUGH. MASS ADJUSTMENT FROM MINNESOTA UPPER PV ANOMALY WILL FORCE A DECENT UPPER LEVEL JETLET TO FORM OVER THE GREAT LAKES TONIGHT. RIGHT ENTRANCE REGION DYNAMICS WILL LIKELY PROVIDE THE IMPETUS FOR ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS IN A WEAKLY UNSTABLE ENVIRONMENT. FURTHERMORE...ANOTHER CONVECTIVELY INDUCED SHORTWAVE CURRENTLY OVER THE PLAINS IS EXPECTED TO ADVECT INTO THE AREA TONIGHT AND AID VERTICAL ASCENT. NO SHORTAGE OF AVAILABLE MOISTURE EITHER WITH 40+ KT SOUTHWESTERLY LLJ CONTINUING TO PUMP HIGH THETA-E AIR INTO THE REGION. EXACT TIMING AND TRACK OF CONVECTION REMAINS UNCERTAIN THOUGH AND WILL DEPEND ON EVOLUTION OF VARIOUS OUTFLOW BOUNDARIES AND MESOSCALE MINUTIA DIFFICULT TO PINPOINT MORE THAN A FEW HOURS IN ADVANCE. LATEST HI-RES ARW AND SPC 4KM WRF SEEM TO HAVE THE BEST HANDLE ON CONVECTION THIS AFTERNOON AND SUGGEST CURRENT DIURNALLY DRIVEN STORMS WILL DISSIPATE AROUND SUNSET WITH A BRIEF LULL BEFORE SECOND WAVE ARRIVES AROUND 06Z. DESPITE GOOD WIND PROFILES...SEVERE WEATHER THREAT WILL DECREASE FURTHER WITH THE LOSS OF DAYTIME HEATING. HEAVY RAIN WILL BE THE MAIN THREAT IF/WHERE CONVECTION DOES OCCUR. MIDLEVEL RIDGING EXPECTED TO REBUILD OVER THE OHIO VALLEY TOMORROW IN RESPONSE TO DIGGING WESTERN CONUS TROUGH. WILL LIKELY STILL BE SOME ONGOING CONVECTION DURING THE MORNING BUT EXPECT A GRADUAL CLEARING TREND DURING THE AFTERNOON AS SUBSIDENCE SPREADS FROM SOUTH TO NORTH. THIS SHOULD ALSO ALLOW FOR A RATHER WARM AFTERNOON. PUSHED HIGH TEMPS UP A BIT TO MATCH WARMER MAV GUIDANCE WITH GENERALLY MID 80S EXPECTED. && .LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY) ISSUED AT 343 PM EDT TUE MAY 28 2013 POTENT SW ACRS THE CNTRL ROCKIES ON NOSE OF STG UPR JET STREAK NOSING IN OFF THE ERN PAC WILL DIG EWD BFR EJECTING INTO THE NRN PLAINS AND CLOSING OFF.
