The episode as NWS IWX wrote it up.
A supercell developed ahead of a cold front in Illinois and tracked east-southeast through Benton county into White county. This storm produced three tornadoes across Indiana, an EF0 in Eastern White County (which moved into Carroll County), an EF1 which started in eastern Carroll County and moved into Cass County, and a third, a stronger EF3 which formed near the Grissom Air Force base in Cass County and moved rapidly east into Miami County. Despite the tornadoes occurring during the overnight hours, no fatalities occurred.
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 5, 6:39 PM EST, 5 hours 1 minute earlier.

.AVIATION...
COMPLICATED AND BUSY TAF PD AS CONVECTION TO THE WEST GETS GOING
IN EARNEST OVER THE NEXT FEW HOURS. MAIN FOCUS FOR WIDESPREAD
DEVELOPMENT OVER EASTERN IOWA IS EXPECTED TO CONGEAL INTO AN MCS
WITH POTENTIAL FOR STRONG WINDS AND MARCH EAST. AHEAD OF
THIS...ADDNL DEVELOPMENT TAKING PLACE AS BOTH LLEVEL AND MID LEVEL
JET SUPPORT INCREASE ATOP AN UNSTABLE BOUNDARY LAYER. THIS
POTENTIALLY IMPACTS KSBN VERY SOON NEAR 00Z AND HAVE USED EARLY
TEMPO FOR THIS WINDOW...WHILE LATER TEMPO GROUP PRESENT BOTH
TERMINALS HANDLES EXPECTED PASSAGE OF BROAD AREA OF THUNDERSTORMS
OVERNIGHT. BEHIND THIS COMPLEX LINGERING SHRA AND MVFR CIGS ARE
EXPECTED WITH SLOW IMPROVEMENT ON SUNDAY. DIFFICULT TO GAUGE WHEN
LOW CIGS MAY RELEASE AS MODELS SHOW SHRINKING DEWPOINT DEPS WITH
COLD AIR ADVECTION SUNDAY MORNING...AND FOR NOW HAVE
OPTIMISTICALLY SCATTERED OUT KSBN BY EARLY AFTERNOON. WINDS
VEERING AROUND TO NW THROUGH THE NIGHT AS SFC WAVE RIDES ALONG
FRONTAL BOUNDARY WHICH PASSES TO OUR SOUTH LATE TONIGHT.

.PREV DISCUSSION... /ISSUED 232 PM EDT SAT JUN 5 2010/
SHORT TERM...
TONIGHT THROUGH SUNDAY NIGHT...
CONVECTION FROM EARLIER THIS MORNING AND RESULTING CLOUD SHIELD OVER
THE AREA HAS SHIFTED INSTABILITY AXIS AND FOCUS FOR CONVECTIVE
REDEVELOPMENT TO OUR SE SO FOCUS TURNS TO ARRIVAL OF BETTER SYNOPTIC
SCALE FORCING THIS EVENING AND RESULTING REDEVELOPMENT ALONG
APPROACHING FRONTAL WAVE. LARGE SCALE FORCING AT ALL LEVELS EXPECTED
THIS EVENING AS FRONTAL WAVE WILL BE ACCOMPANIED BY 50KT LLJ WHICH
WILL AID IN GOOD LOW LEVEL MOISTURE TRANSPORT...60-70KT MID LEVEL
SPEED MAX...AND ENHANCED UPPER LEVEL DIVERGENCE WITH UPPER JET OVER
GREAT LAKES REGION. ALL THESE INGREDIENTS WILL COMBINE WITH PW
APPROACHING 2 INCHES SO WILL CONTINUE WITH GOING FCST OF LIKELY POPS
AND MENTION OF HVY RAIN. TIMING IN GRIDS STILL ON TRACK AS FRONT
EXPECTED TO MOVE THROUGH THE AREA BY EARLY SUNDAY MORNING...WHICH
SHOULD CLEAR PRECIP OUT OF THE AREA BY MID MORNING. LINGERING CLOUD
COVER AND DECENT CAA BEHIND FRONT SUGGEST MODELS ON TRACK WITH MUCH
COOLER TEMPS SUNDAY...ESPECIALLY MICHIGAN COUNTIES WHERE MORE
EXTENSIVE CLOUD COVER IS EXPECTED. WEAK SFC RIDGING WILL BRING
COOLER DRIER AIRMASS INTO THE AREA SUNDAY NIGHT BRINGING LOWS BACK
DOWN INTO THE 50-55 DEG RANGE.
LONG TERM...
..MONDAY THROUGH SATURDAY...
A COUPLE SYSTEMS OF INTEREST TO WATCH IN THE LONG TERM PERIOD ALONG
WITH POTENTIAL SIGNIFICANT WARMING LATE IN THE PERIOD. GENERALLY
PREFER ECMWF BLENDED WITH CURRENT GRIDS FOR FORECAST DETAILS AND
CONSISTENCY. GFS IN AGREEMENT ON OVERALL PATTERN AS WELL WITH
DIFFERENCES IN TIMING OF FEATURES AS IT LOOKS MUCH FASTER THAN ECMWF
WITH TRANSITION OUT OF ZONAL FLOW PATTERN.
MID LEVEL FLOW WILL BE ZONAL ACROSS THE CONUS TO START THE PERIOD
BUT WILL TRANSITION TO MORE MERIDIONAL FLOW BY THE END OF THE PERIOD
WITH DEVELOPING TROUGH IN THE WESTERN CONUS AND RIDGING IN THE EAST.
THIS SHOULD LEAD TO GRADUAL WARMING OVER THE AREA WITH POTENTIAL FOR
TEMPERATURES INTO THE 90S BY NEXT WEEKEND IF CURRENT SOLUTIONS ARE
CORRECT.
HIGH PRESSURE WILL BE OVER THE AREA ON MONDAY WITH TEMPERATURES NEAR
OR JUST BELOW SEASONAL NORMALS. THIS HIGH WILL SLIDE TO THE EAST
MONDAY NIGHT WITH ANOTHER ROUND OF FAST MOVING WEAK SHORT WAVES AND
POTENTIAL MCS ACTIVITY WHICH COULD IMPACT OUR AREA TUESDAY INTO
WEDNESDAY. LOW LEVEL BAROCLINIC ZONE LOOKS TO BE ACROSS THE REGION
WITH WEAK SURFACE FRONT AND POSSIBLE SURFACE DEVELOPMENT TUE NIGHT
INTO WED. MUCH TOO EARLY FOR MANY FORECAST DETAILS WITH THIS
SCENARIO SO WILL CONTINUE WITH LOW CHANCE POPS THROUGH THIS PERIOD.
MEANWHILE...ENERGY OVER THE PACIFIC WILL HELP DEVELOP A CLOSED LOW
ALONG THE WESTERN CONUS WHICH WILL ALSO HELP TO CARVE OUT A WESTERN
CONUS TROUGH AND ALLOW HEIGHTS TO RISE OVER OUR AREA. ECMWF BRINGS A
WARM FRONT THROUGH THE REGION FRIDAY AFTERNOON INTO FRIDAY NIGHT
WITH POSSIBLE MCS DEVELOPMENT IN THE AREA. HAVE INCLUDED LOW CHANCE
POPS FOR WARM FRONT PASSAGE FRIDAY AFTN INTO FRI NIGHT. THIS SHOULD
ALSO HELP CAP THE REGION ON SAT WITH FRONT TO OUR NORTH AND STRONG
UPPER LEVEL RIDGE DEVELOPING SO REMAINED OPTIMISTICALLY DRY ON DAY 7
WITH VERY WARM TEMPS INTO THE UPPER 80S BUT 90S COULD EASILY OCCUR
WITH RIDGE AND FULL SUN.

BMLThe Northern Indiana radar (KIWX), 43 km away, was scanning. The volume nearest the first event began at 04:40 UTC.
5 thunderstorm wind, 4 tornado. Local standard time, as filed.
Emergency management officials reported trees and tree limbs down across the northwestern parts of the county.
Emergency management officials reported a large tree down at County Road 900 West and State Route 120.
Emergency management officials reported trees down in the area, with one onto a house.
A survey of damage in eastern White county revealed indications of a weak circulation touching down just south of County Road East 450 South, on County Road South 300 East. The circulation passed over a farm where tree damage occurred as it moved east. Skylights from a shed were blown towards the east with one being found behind a house. Damage was done to roofing of a new pole barn and several items were thrown into a field towards a grove of trees. The tornado began to intensify somewhat but remained over open fields until reaching the Stone Drive area on the west side of Lake Freeman where numerous trees (DI: TS, DOD: 3) were uprooted with some structure damage. The tornado then exited White County over Lake Freeman into Carroll County (see Storm Data for Indiana, Central). Maximum winds are estimated to range between 80 and 85 mph. Damage is estimated at $200,000 from a combination of cleanup of trees and structure damage.
Emergency management officials reported trees down in the Fremont area, one of which fell onto a house. No further damage details were provided.
This tornado developed in eastern Carroll County, Indiana, roughly four miles east-southeast of Burrows (see Storm Data for Indiana, Central) and moved into Cass County. The tornado initially was over open fields with its first impact at a residence where the western half of the roof was ripped off and the eastern half picked up and then dropped back down. Two residents were attempting to take shelter when the tornado hit. A gentleman suffered minor injuries (indirect) falling down a stairway into a basement seeking shelter. The tornado continued east-southeast over mainly open field again until it encountered a more populated area of structures along E County Road 900 S, east of S County Road 300 E. Several trees were damaged or uprooted in the area with the western half of a business being destroyed by the circulation. The circulation moved on to strike and roll a mobile home, destroying it (DI: SWMH DOD: 7). The second injury (direct) in the area occurred here where the resident was rolled with the mobile home. The female resident escaped with minor injuries. The circulation continued on causing some structure and tree damage before dissipating. The maximum width is estimated at 150 yards with a maximum wind speed estimated around 100 mph.
After a brief break, the supercell produced one more circulation which touched down just west of the Cass/Miami county line along South County Road 1000 East. Several yards in the area had trees uprooted and limbs down (DI: TH, DOD: 4). A few residences were impacted by the trees, causing mainly roof or window damage. The circulation then went into a dense grove of trees with the circulation briefly weakening before coming back out near the Grissom Air Reserve Base. A 200 foot section of security fence on the southwest corner of the base was blown down into the adjacent roadway and portions of the nearby field before crossing into Miami County. An Automated Weather Observation System recorded a 114 mph wind gust as the circulation passed through.
The tornado that entered this county exited the Grissom Air Reserve base on the Cass/Miami county line and continued east-southeast, crossing a small area of trees where signs of slight debarking was noted (DI: TH DOD: 5). The tornado continued on along to the 3000 block of County Road 900 South where the most substantial damage occurred to a one and one half story home. Only a few kitchen walls remains of the structure (DI: FR12, DOD 8) with one resident in the kitchen and one in the basement. Two other residences suffered extensive damage but remained intact. The tornado crossed US 31 and continued for a few more miles, causing some additional tree and structure damage including several buildings at a hog farm being destroyed. The tornado eventually dissipated east of Strawpike Road, north of East 1000 South in a field. A local newspaper article reported that a check that was originally located at the destroyed home was found nearly 50 miles away in Wells County in perfect condition. Total damage along the track of the tornado is estimated at $750,000.
A trained spotter reported tree limbs were blown down.
