The episode as NWS IWX wrote it up.
A cold front moved through the region during the afternoon and evening hours with moderate instability in place ahead of the front. An upper level disturbance aided in enhancement of showers and thunderstorms that developed. Sporadic wind damage was reported across northwestern Ohio.
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 Aug 19, 3:35 PM EST, 1 hour 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 435 PM EDT TUE AUG 19 2014 .SYNOPSIS... ISSUED AT 430 PM EDT TUE AUG 19 2014 A WEAK COOL FRONT WILL TRACK ACROSS THE OHIO VALLEY TONIGHT. THIS WILL RESULT IN DIMINISHING COVERAGE TO SHOWERS AND THUNDERSTORMS THIS EVENING. A WEAK RIDGE OF HIGH PRESSURE WILL SETTLE INTO THE AREA...WITH JUST A LOW CHANCE OF AFTERNOON SHOWER OR THUNDERSTORM ACROSS SOUTHEAST LOWER MICHIGAN...FAR NORTHEAST INDIANA...AND NORTHWEST OHIO. LOW TEMPERATURES TONIGHT WILL DROP INTO MID 60S. HIGH TEMPERATURES ON WEDNESDAY WILL RANGE FROM THE UPPER 70S ACROSS CENTRAL LOWER MICHIGAN...TO THE LOWER TO MID 80S ACROSS CENTRAL INDIANA. && .SHORT TERM...(THIS EVENING THROUGH WEDNESDAY) ISSUED AT 430 PM EDT TUE AUG 19 2014 SHOWERS AND THUNDERSTORMS HAVE INCREASED IN COVERAGE ALONG WEAK COOL FRONTAL BOUNDARY. LARGE SCALE FORCING HAS ALSO BEEN AIDED BY A PAIR OF UPPER LEVEL DISTURBANCES...ONE MOVING INTO THE WESTERN GREAT LAKES...AND ANOTHER CONVECTIVELY ENHANCED VORT MAX WORKING EASTWARD OUT OF CENTRAL ILLINOIS. AN AXIS OF 1500-2500 SBCAPES EXISTS DOWNSTREAM OF STORMS...ALTHOUGH DEEP LAYER SHEAR PROFILES REMAIN SOMEWHAT ON THE MARGINAL SIDE IN THE 20 TO 30 KNOT RANGE SUGGESTING COLD POOL BALANCE MAY BE INCREASINGLY DIFFICULT TO ATTAIN. SOME LOW END SEVERE THREAT WILL EXIST OVER AT LEAST THE NEXT FEW HOURS INTO NORTHEAST INDIANA/NORTHWEST OHIO...MAINLY IN THE FORM OF ISOLATED DAMAGING WIND GUSTS. WITH MID/UPPER LEVEL FORCING LINGERING UPSTREAM ACROSS THE WESTERN GREAT LAKES...ADDITIONAL ISOLATED OR SCATTERED SHOWERS AND THUNDERSTORMS MAY STILL DEVELOP IN THE WAKE OF PRIMARY CONVECTION...BUT CURRENTLY NO SEVERE RISK IS ANTICIPATED WITH ANY POTENTIAL REDEVELOPMENT LATER THIS EVENING. WEAK GRADIENT AND LINGERING LOW LEVEL MOISTURE COULD PROMOTE SOME PATCHY FOG REDEVELOPMENT LATE TONIGHT...OR PERHAPS SOME PATCHY STRATUS. WILL OMIT FOG MENTION FROM THE FORECAST FOR NOW BUT LATE EVENING/EARLY OVERNIGHT TRENDS WILL NEED TO BE MONITORED. ON WEDNESDAY UPPER LOW WILL SLOWLY MEANDER EASTWARD ACROSS THE GREAT LAKES REGION...WITH A FEW WEAK VORT LOBES LIKELY ROTATING AROUND PARENT UPPER LOW INTO ESPECIALLY NORTHEAST PORTIONS OF THE AREA. WILL MAINTAIN SOME LOW POPS ACROSS THE NORTHEAST...AND SHOULD BE TIED TO PEAK HEATING HOURS. NO SIGNIFICANT CHANGE MADE TO TEMPS FOR TONIGHT/WEDNESDAY WITH LOWS IN THE LOWER TO MID 60S AND HIGHS IN THE LOWER TO MID 80S. && .LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY) ISSUED AT 430 PM EDT TUE AUG 19 2014 WARM AND MUGGY CONDITIONS STILL ON SCHEDULE FOR THE GREAT LAKES LATER THIS WEEK AS UPPER LOW EXITS EASTWARD AND RIDGE BUILDS DOWNSTREAM OF DIGGING NORTHERN ROCKIES TROUGH. PRECIP CHANCES AND TIMING REMAIN THE BIGGEST SOURCES OF UNCERTAINTY. WARM FRONT WILL BEGIN TO LIFT NORTH AS EARLY AS WEDNESDAY NIGHT AND THURSDAY MORNING WILL PROBABLY BE THE BEST CHANCE FOR WIDESPREAD PRECIP IN OUR CWA. 305K ISENTROPIC FIELDS SHOW GOOD SYSTEM RELATIVE CROSS-ISOBAR FLOW WITH A MODEST DEGREE OF MOISTURE ADVECTION AS WELL. THE PROBLEM IS THERE IS VERY LITTLE SUPPORT ALOFT GIVEN BUILDING LONGWAVE RIDGE. MIDLEVEL VORTICITY FIELDS SHOW JUST A WEAK AND HIGHLY SHEARED WAVE CASCADING OVER THE RIDGE. EXPECT SCT SHOWERS AND THUNDERSTORMS TO SPREAD FROM SOUTHWEST TO NORTHEAST EARLY THURSDAY MORNING BUT CONFIDENCE IN COVERAGE IS TOO LOW FOR LIKELY POPS AT THIS POINT. THE BIG QUESTION WILL BE HOW MUCH...IF ANY...CONVECTION DO WE SEE THURSDAY AFTERNOON. FORECAST SOUNDINGS INDICATE A HEALTHY CAPPING INVERSION MAY DEVELOP IMMEDIATELY BEHIND THE WARM FRONT. WHERE EXACTLY THE FRONT SETS UP...AND THE TIMING/COVERAGE OF MORNING PRECIP...WILL LIKELY DETERMINE THE LOCATION AND DEGREE OF AFTERNOON CONVECTION. FOR NOW...EXPECT THE BEST CHANCES IN OUR NORTHEAST ZONES. DECENT MIDLEVEL LAPSE RATES AND VERY MOIST ENVIRONMENT NEAR THE SURFACE GENERATES AROUND 2000 J/KG OF MLCAPE BY THURSDAY AFTERNOON ACCORDING TO THE LATEST GFS AND NAM. WITH 0-6KM SHEAR VALUES AT OR ABOVE 30 KTS...THERE WILL BE POTENTIAL FOR SEVERE WEATHER. IT IS A HIGHLY CONDITIONAL THREAT THOUGH...DEPENDENT ON EVOLUTION OF MORNING CLOUDS/PRECIP AND DEGREE OF FORCING LEFT IN OUR CWA. LOWER CHANCES FOR PRECIP EXPECTED FRIDAY AND SATURDAY AS THERMAL RIDGE PUSHES NORTHEAST AND CAP STRENGTHENS. GFS IS VERY AGGRESSIVE WITH CONVECTIVE QPF BUT ALSO HAS SURFACE DEWPOINTS NEAR 80F. SUSPECT A MORE REALISTIC SURFACE DEWPOINT IN THE LOW TO MID 70S WILL BE INSUFFICIENT TO BREAK THROUGH THE CAPPING INVERSION GIVEN LITTLE TO NO TRIGGER MECHANISM. KEPT JUST A SLIGHT CHANCE WITH DRY CONDITIONS EXPECTED SUNDAY AND MONDAY. AS PREVIOUSLY MENTIONED IT WILL BE VERY WARM THOUGH. COULD SEE THE HOTTEST CONDITIONS OF THE YEAR THIS WEEKEND. 850MB TEMPS CLIMB TO AROUND 20C...SUPPORTING HIGHS AROUND 90F. AND DEWPOINTS IN THE LOW TO MID 70S WOULD PUSH HEAT INDEX VALUES TO NEARLY 100F. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON) ISSUED AT 1253 PM EDT TUE AUG 19 2014 INCREASING LARGE SCALE SUPPORT IN TERMS OF A PAIR OF UPPER LEVEL DISTURBANCES TRACKING ACROSS THE REGION COMBINED WITH WEAK LOW LEVEL FRONT WILL ALLOW FOR INCREASING SHOWER/THUNDERSTORM COVERAGE ACROSS NORTHERN INDIANA EARLY THIS AFTERNOON. BEST CHANCES OF TSRA AT ONSET OF TAF VALID PERIOD WILL BE AT KSBN...WITH CHANCES INCREASING TO KFWA CLOSER TO THE 20-21Z TIMEFRAME. SOME OF THE STORMS MAY PRODUCE SOME GUSTY WINDS IN EXCESS OF 35 KNOTS. GREATEST THUNDERSTORM COVERAGE IS ANTICIPATED FOR THE 19Z-22Z TIMEFRAME AT KSBN AND FROM ROUGHLY 21Z-00Z AT KFWA. WEAKENING FRONTAL BOUNDARY...RESIDUAL LOW LEVEL MOISTURE...AND LIGHT GRADIENT WILL LIKELY PROMOTE PATCHY FOG/STRATUS DEVELOPMENT AGAIN OVERNIGHT AND HAVE TRENDED FORECAST TO MVFR CONDITIONS AFTER 06Z. DETAILS IN THIS REGARD WILL HAVE TO BE FINE TUNED IN UPCOMING FORECASTS. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
