The episode as NWS IWX wrote it up.
A warm front worked north towards Lower Michigan during the evening hours of the 5th. Storms were initially slow to organize, but quickly intensified and became super-cellular. One of these storms tracked into Fulton County and quickly spawned a tornado north of Liberty Center. The tornado remained on the ground for roughly 7 miles producing damage along its track before dissipating near the Fulton/Lucas county line.
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 4, 10:08 PM EST, 1 hour 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 1108 PM EDT FRI JUN 4 2010 .UPDATE... WILL BE DROPPING THE REMAINDER OF THE WATCH ONCE ACTIVITY HAS CLEARED THE FAR SOUTHERN COUNTIES. STORMS ARE WEAKENING AS WE SPEAK AND ARE LIKELY NO LONGER SEVERE BUT WILL WAIT FOR THEM TO CLEAR THE AREA. WILL MAINTAIN 30 TO 40 POPS INTO THE OVERNIGHT HOURS. UNSTABLE ATMOSPHERE STILL IN PLACE ACROSS MUCH OF THE AREA SO HIT AND MISS SHOWERS AND STORMS STILL EXPECTED. FOCUS WILL TURN TO THE WEST LATER TONIGHT INTO SATURDAY. SCATTERED SHOWERS AND STORMS CONTINUE TO FIRE ACROSS PORTIONS OF ILLINOIS INTO MISSOURI. SPC MESOANALYSIS PAGE SHOWS STRONG SFC THETA E ADVECTION AND CONVERGENCE FROM NORTHERN NEBRASKA TO SOUTHERN IOWA WITH LLJ FEEDING INTO THESE AREAS. QUESTIONS REMAIN AS TO WHETHER NEW ACTIVITY WILL FIRE IN THIS AREA OR IF SHOWERS AND STORMS ACROSS NORTHERN NEBRASKA WILL MOVE INTO THE BETTER MSTR FEED AND INTENSIFY. THINGS TO BE MONITORED OVERNIGHT. && .PREV DISCUSSION... /ISSUED 745 PM EDT FRI JUN 4 2010/ AVIATION... DIFFICULT AVIATION FORECAST WITH RESPECT TO CONVECTIVE CHANCES AT TAF SITES THIS PERIOD. SHORT WAVE PASSING THROUGH THE GREAT LAKES GENERATING SCATTERED CONVECTION ALL AROUND THE AREA BUT NO IMMEDIATE IMPACTS AT TAF LOCATIONS. KFWA LOOKS TO HAVE BEST CHANCE AT TSRA LATER THIS EVENING BUT EVEN THAT MAY BE A GLANCING BLOW AS RADAR SHOWS CONVECTION IN NORTHWEST INDIANA SLIDING SOUTHEAST AT CURRENT TIME. INCLUDED A TEMPO GROUP FOR THIS PASSAGE. MODELS RATHER AGGRESSIVE WITH DEVELOPING A STRONG MESOSCALE CONVECTIVE COMPLEX UPSTREAM TONIGHT AND RIDING IT EAST INTO OUR AREA SATURDAY. PROBLEM LIES WITH RATHER POOR HANDLING OF CURRENT CONVECTION TO OUR SOUTHWEST WHICH APPEARS FURTHER SOUTH THAN MODEL FORECASTS. WILL KEEP A CB MENTION AT KSBN TOMORROW AND A VCTS AT KFWA BUT CONFIDENCE LOW UNTIL WE SEE HOW THINGS DEVELOP UPSTREAM OVERNIGHT. COULD CERTAINLY BE A PROLONGED WINDOW OF MODERATE TO HEAVY RAIN WITH TSRA AND MVFR TO IFR CIGS WITH THIS CONVECTIVE COMPLEX BUT LOCATION REMAINS TOO UNCERTAIN FOR GREATER WX IN TAFS AT THIS TIME. SHORT TERM... TONIGHT THROUGH SATURDAY NIGHT... SFC FRONTAL BOUNDARY WITH MULTIPLE WAVES TO IMPACT THE AREA IN THE SHORT TERM. FIRST ROUND ALREADY INITIATING IN EXTREME SE CWA AS BOUNDARY LAYER QUICKLY DESTABILIZING. VIS SAT DEPICTING CONVERGENT BOUNDARY WITH ENHANCED CU FIELD FROM FDY TO AOH TO MIE. MID LEVEL SUPPORT MAKING ITS WAY ACROSS CENTRAL GREAT LAKES AS WELL WITH KGRR VWP INDICATING MODEST 50KT SPEED MAX AT 500MB. NORTHWARD PUSH OF SFC FRONTAL BOUNDARY EXPECTED TO CARRY THIS FEATURE JUST NORTH OF THE CWA RESULTING IN INC LOW LEVEL MOISTURE AND CONTINUED DESTABILIZATION...BUT ALSO LEAVING LIMITED FORCING AND FOCUS FOR CONVECTION THIS EVENING. AS A RESULT...PLAN TO LEAVE POPS IN CHANCE RANGE FOR TONIGHT AS FOCUS THEN SHIFTS TOWARD ARRIVAL OF NEXT WAVE RIDING ALONG THE BOUNDARY SATURDAY MORNING. LOW LEVEL FORCING TO ORGANIZE BACK IN CENTRAL PLAINS OVERNIGHT IN SUPPORT OF NOCTURNAL MCS DEVELOPMENT AS STRONG MOISTURE TRANSPORT AIDED BY 50+KT LLJ NOSES INTO SOUTHERN IA OVERNIGHT. EVOLUTION OF THIS FEATURE TO GO A LONG WAY IN DETERMINING OUTCOME OF SENSIBLE WEATHER FOR OUR AREA ON SATURDAY. MODEL INDICATIONS ATTM POINT TOWARD AN EASTWARD PROPAGATING MCS AS IT RIDES ALONG 850-300MB THICKNESS RIDGE INTO OUR WESTERN CWA. WILL REWORK MORNING WX GRIDS ACCORDINGLY TO ACCOUNT FOR THIS...BUMPING UP TO LIKELY IN WESTERN HALF. LOW LEVEL FORCING TO MAINTAIN INTO SATURDAY AS LLJ PUSHES INTO NORTHERN ILLINOIS BY 18Z. THIS WILL BE ACCOMPANIED BY SFC FRONTAL WAVE AND LENDS SUPPORT TO A REGENERATIVE MCS TYPE PATTERN. COMBINE THIS WITH PW PROGGED TO BE IN THE 1.5-2.0 INCH RANGE AND POTENTIAL FOR HEAVY RAIN CERTAINLY IN PLAY SATURDAY AFTN/EVENING. TEMPS THROUGH THE PERIOD APPEAR ON TRACK AND ONLY MINOR ADJUSTMENTS MADE. LONG TERM.../SUNDAY THROUGH THURSDAY/... ON SUNDAY SFC LOW WILL BE MOVING AWAY TO THE EAST YET STILL PULLING COLD FRONT/INVERTED TROUGH BEHIND INTO THE AREA EARLY. 12Z NAM/9Z SREF FASTEST CLEARING THE CWA WITH 12Z GFS/ECMWF SLOWER AND MAINTAINING SHRA IN THE EAST EARLY. WITH MIXED GUIDANCE WILL RETAIN EARLY SUNDAY CHC POP FOR EASTERN AREAS AFTER WHICH COOLER DRIER AIR OVERSPREADS THE REGION AS ZONAL FLOW ALOFT BUCKLES SOMEWHAT INTO MILD TROUGHING OVER THE GREAT LAKES. NAM12/GFS ALSO TRY TO FIRE SOME LIGHT SHRA AS WEAK MID LEVEL SHRTWV DROPS THROUGH NW FLOW BUT GIVEN DRY AIR PERMEATING LOWER LEVELS WILL CONTINUE TO RIDE DRY GRID AT THIS TIME. QUIETER PERIOD THEN APPEARS IN STORE THOUGH SIGNIFICANT MODEL DIFFERENCES ARE BEGINNING TO APPEAR. OP GFS HOLDS ON TO STRONGER RIDGING OVER THE PLAINS KEEPING A STEEPER AND COOLER NW FLOW ALOFT OVER THE REGION...WHILE THE ECMWF REMAINS MORE ZONAL FLOW. BOTH DEVELOP MCS ACTIVITY UPSTREAM TUESDAY AND BRING IT EASTWARD...BUT THE MORE AMPLIFIED GFS ROLLS THIS ACTIVITY SOUTH OF THE CWA. AGAIN CHC POPS ARE REASONABLE THOUGH IF CURRENT GFS/GFS ENSEMBLE MEAN TIMING REMAINS CONSISTENT A FORWARD ADJUSTMENT IN TIME COULD BE NEEDED.. LATE PERIOD GFS THEN PROGRESSES ITS EARLIER AMPLIFICATION DOWNSTREAM WHILE THE ECMWF INTENSIFIES RIDGE CENTERED ALONG GULF COAST. IN BOTH CASES THIS FORESHADOWS A WARMING TREND THOUGH WITH THE MED RANGE MODELS DIFFERING IN THE MECHANISM WILL REMAIN CONSERVATIVE WITH LATE PD TEMPS INCREASING INTO THE LOW 80S&& && .IWX WATCHES/WARNINGS/ADVISORIES...

EVENT NUMBER IWX1000634
FISHERThe Cincinnati radar (KILN), 148 km away, was scanning. The volume nearest the first event began at 05:00 UTC.
2 thunderstorm wind, 1 tornado. Local standard time, as filed.
A local newspaper reported a large tree fell onto a house and garage in the 600 block of Nixon Avenue in Lima. No information was provided in terms of damage to the structures.
Law enforcement officials reported a tree being blown down onto a vehicle. No damage estimates were available.
The tornado touched down along Highway 109 just north of County Road A and moved northeast, impacting several homes, trees and power lines. Several homes were severely damaged or destroyed (DI:FR12 DOD: 8). However, improper anchoring of some of the homes resulted in a failure on all walls, resulting in their destruction. Several trees were uprooted or damaged, including through the Maumee State Forest. The tornado ended near the Fulton/Lucas county line. The maximum width of the tornado was around 700 yards with maximum wind speeds estimated around 130 mph. Damage is estimated at $500,000.
