Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS IWX wrote it up.
A cold front moved slowly through the area during the early evening hours. While overall instability was modest, strong wind fields were in place. An area of storms developed in far eastern Indiana and tracked northeast into Paulding county. This area produced sporadic damage across the county before weakening.
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 Apr 7, 6:42 PM EST, 24 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 742 PM EDT WED APR 7 2010 .UPDATE... WATCH HAS BEEN CANCELLED A BIT AHEAD OF SCHEDULE. MAIN LINE OF SHOWERS AND STORMS HAS EXITED THE WATCH AREA. SOME REFLECTIVITY SIGNATURES OF HIGHER WIND POTENTIAL BUT NOTHING HAS BEEN MAKING IT TO THE GROUND IN AREA OF CAPPING STILL BEING NOTED ACROSS EASTERN SECTIONS. LINE WILL CONTINUE TO PROGRESS EAST AND MAY HAVE SOME STRONGER WINDS GUSTS HERE AND THERE BUT MAIN ISSUE WILL BE THE HEAVY RAIN AT TIMES. HAVE UPDATED GRIDS TO KEEP CAT POPS THE REMAINDER OF THE EVENING ALONG AND EAST OF THE LINE...BUT IF TRENDS CONTINUE WILL NEED ANOTHER UPDATE TO TONE THINGS DOWN FURTHER. WEST OF THE LINE...SCT SHOWERS HAVE BEEN TRYING TO STAY TOGETHER. LITTLE OR NO LIGHTNING HAS BEEN NOTED IN THIS AREA WHICH HAS BEEN QUITE WORKED OVER AND IN AN INCREASINGLY STABLE AIRMASS. COLD FRONT IS WORKING ACROSS EASTERN ILLINOIS AND WILL BE THE LAST CHANCE FOR ANY ACTIVITY TO FORM FOR WESTERN AREAS. FOR NOW HAVE OPTED TO GO WITH SCT SHOWERS GIVEN COVERAGE ATTM AND HOLD THROUGH THE EVENING. AS WITH EASTERN AREAS...UPDATE MAY BE NEEDED IN A FEW HOURS BUT WANTED TO AT LEAST CLEAN GRIDS UP SOMEWHAT WITH DROPPING OF THE WATCH. && .AVIATION /00Z TAFS/... LOW PRESSURE SLIGHTLY FURTHER NE SINCE LAST ISSUANCE BUT MAKING A HEADING TOWARDS NORTHWEST INDIANA. RAIN SHOWERS WITH EMBEDDED THUNDERSTORMS CONTINUE TO MOVE THROUGH THE AREA THIS EVENING AND AFFECT THE TERMINALS...HOWEVER...THE MAIN ISSUE THIS PD WILL BE CIGS. BEHIND THE COLD FRONT AND IN THE DRY SLOT...PARTLY TO MOSTLY CLEAR SKIES ARE BEING REPORTED. EXPECT THIS TO MAKE A BRIEF APPEARANCE AT KSBN AND A LONGER STAY AT KFWA UNTIL LOW PRES MOVES FURTHER TO THE NE WHERE FLOW WILL THEN VEER AND BECOME NW. LL FLOW AT THAT TIME WILL FINALLY ALLOW THE IFR CIGS SEEN ACROSS PORTIONS OF ILLINOIS TODAY TO MOVE INTO KSBN OVERNIGHT. WILL NEED TO MONITOR LATER FORECAST AS FAR AS TIMING OF LOW CIGS AS CONFIDENCE AT THIS POINT IS RATHER LOW WITH SLOW MOVEMENT OF LOW PRES AND MODELS NOT HANDLING THE LOW CIGS ACROSS THE TERMINALS TODAY VERY WELL AT ALL. WILL MONITOR FOG TRENDS FOR ADDITION TO TAFS...BUT LOW OVERALL CONFIDENCE GIVEN MARGINAL WINDS UPSTREAM. && .PREV DISCUSSION... /ISSUED 242 PM EDT WED APR 7 2010/ SHORT TERM.../TONIGHT THROUGH THURSDAY NIGHT/ SFC LOW OVER WEST CENTRAL IL WITH A STNRY FRONT EXTENDING NE FROM THE LOW INTO SE MI. LOW EXPECTED TO TRACK NE ALONG THE STNRY FRONT ACROSS OUR CWA TONIGHT. CLOUDS AND OUTFLOW FROM BANDS OF SHOWERS/TSTMS HAVE LIMITED HEATING ACROSS MUCH OF OUR AREA TODAY...HWVR AS THE LOW APPROACHES LATE THIS AFTN WK INSTABILITY WITH MUCAPES 500-1000J/KG SHOULD ADVECT INTO THE AREA WHICH SHOULD BE SUFFICIENT FOR TSTMS TO CONT TO DVLP LATE THIS AFTN/EVE. WK INSTABILITY AND RATHER SMALL MID LEVEL LAPSE RATES ARE THE MAIN LIMITING FACTORS FOR SVR STORMS THIS AFTN/EVE. HWVR, 70KT 0-6KM SHEAR EVIDENT ON WOLCOTT PROFILER SUGGESTS THERE IS STILL A POTENTIAL FOR SOME STORMS WITH LARGE HAIL/DAMAGING WINDS...ESPCLY S-SE PORTION OF CWA WHERE GREATEST INSTABILITY IS EXPECTED. ALSO WITH STNRY FRONT OVER THE AREA PROVIDING A BOUNDARY TO ENHANCE STORM INFLOW ALONG WITH BACKING FLOW AND INCRSG 0-3KM HELICITY EVIDENT ON WOLCOTT PROFILER, A THREAT FOR LOW TOPPED SUPERCELLS AND TORNADOES EXISTS...HENCE RECENTLY ISSUED TORNADO WATCH FOR SW PORTION OF CWA. AS LOW MOVES NE OF THE AREA LATE TONIGHT, CAA WILL OVERSPREAD THE ENTIRE CWA AND BRING AN END TO THE TSTM THREAT. COLD/MOIST CYCLONIC FLOW...AIDED BY DEEP MID LEVEL TROF PASSAGE SHOULD RESULT IN AT LEAST SCT SHOWER COVERAGE ACROSS THE AREA ON THU. TEMPS WILL BE BLO NORMAL WITH HIGHS RANGING FROM THE L40S NW TO L50S SE AND A BRISK NW WIND OVER THE ENTIRE AREA. 1000-850MB MODEL THICKNESS FCSTS SUGGESTS IT WILL BE COLD ENOUGH FOR SNOW ACROSS NW PORTION OF THE CWA ON THU/THU EVE...HWVR MOISTURE IS EXPECTED TO BE MAINLY BLO DGZ... SO EXPECT PRECIP WILL MAINLY BE RAIN... THOUGH SOME SLEET IN HEAVIER SHOWERS NOT OUT OF THE QUESTION. SCT SHOWERS SHOULD END THU NGT AS MID LEVEL TROF MOVES EAST OF THE AREA AND DIURNAL HEATING WANES. CONSIDERABLE CLOUDINESS AND BOUNDARY LAYER MIXING SHOULD CONT OVERNIGHT SO LEANED TOWARD THE WARMER MOS TEMPS FOR LOWS THU NGT. LONG TERM...FRIDAY THROUGH WEDNESDAY ONLY MINOR TWEAKS TO THE FCST GIVEN RELATIVELY GOOD RUN TO RUN MODEL CONSISTENCY. FRIDAY WILL FEATURE DRY CONDITIONS AND DECREASING CLOUDS IN RESPONSE TO LARGE SCALE SUBSIDENCE / 12 HR 120M 7-5H HEIGHT RISES...AS INITIAL FULL LATITUDE TROUGH PIVOTS EAST OF THE REGION WITH NW FLOW ALOFT. STILL RATHER COOL THERMAL PROFILES ON FRI ON BACKSIDE OF UPPER TROUGH...WITH MODELS AGREEING ON 85T NEAR -5C BY 18Z FRI. MIXING FROM THERE WOULD YIELD MID/UPPER 40S FOR HIGHS...WHICH IS A GOOD 5-8 DEGREES COOLER THAN INHERITED FCST HIGHS. AS A RESULT...TRENDED HIGHS DOWN 1-3 DEGREES FOR NOW WHICH MATCHES UP WELL WITH LATEST MEXMOS. ABOVE NORMAL TEMPS AND DRY CONDITIONS ARE EXPECTED THIS WEEKEND INTO MUCH OF NEXT WEEK AS SFC-85H RIDGE SETS UP OVER THE SOUTHEAST US IN RESPONSE TO UPSTREAM TROUGHINESS ACROSS WESTERN NOAM. ONLY SLIGHT CONCERN FOR ANY SHRAS WOULD BE SUN INTO MON MORNING. UPPER VORTEX NEAR THE ALEUTIANS/GULF OF ALASKA WILL SINK SEWD INTO WESTERN CANADA LATE THIS WEEK. SHRTWV ENERGY EMANATING OUT OF THIS WILL TRACK INTO THE NRN LAKES...DRAGGING A FRONTAL BOUNDARY SWD INTO AT LEAST THE CENTRAL GREAT LAKES BY SUN/MON. WILL STAY DRY DURING THIS TIME GIVEN LACK OF ANY APPRECIABLE GOMEX MOISTURE RETURN AND BULK OF MODEL GUIDANCE KEEPING THIS BOUNDARY NORTH OF THE FA.

3 thunderstorm wind. Local standard time, as filed.
Emergency management officials reported west facing barn doors were blown into the barn with north facing doors blown out. Damage was estimated at $10,000.
Emergency management officials reported that damage was observed along a roughly half mile long path. The damage started near the intersection of county highway C-105 and U.S. 24. Two mobile homes that were attached together, were flipped over, destroying it. As the wind continued east a pole barn next to the mobile home was destroyed. Along U.S. 24, several trees were uprooted in two separate residences. Two homes suffered roof damage as well. The damage ended just across the Maumee River where several large broken tree limbs were found along the river bank. The combined damage is estimated at $100,000.
Law enforcement officials reported trees and power lines down across mainly the southern parts of the county. Damage is estimated at $20,000.
