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.

What happened

The episode as NWS IWX wrote it up.

Influenced by a highly unstable, but strongly capped atmosphere ahead of a frontal boundary moving out of Illinois, the combination of 3000 to 4000 j/kg surface based CAPE, mid-level lapse rates between 8 and 9 C/km and 0-6 km deep layer shear of 35 to 55 knots set the stage for rapid supercellular development. The convection transitioned to clusters of bowing segments as storms congealed producing an increased risk for high end damaging wind. Broad, but strong rotation established quickly in the initial storms, allowing for rapid production of hail, some exceeding gold ball size. Numerous funnel clouds were reported in the early stages of the event, indicating conditions were favorable for tornadic development. However, the development of tornadoes was severely limited due to just enough mixed layer inhibition in the lowest levels.

What forecasters said that day

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 12, 9:10 PM EST, 1 hour 17 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
1010 PM EDT WED JUN 12 2013

.SYNOPSIS...
ISSUED AT 250 PM EDT WED JUN 12 2013

A WARM FRONT HAS SETTLED ACROSS SOUTHERN MICHIGAN. SEVERAL
DISTURBANCES ARE EXPECTED TO RIDE ALONG THIS BOUNDARY...BRINGING
ONE OR MORE ROUNDS OF SHOWERS AND THUNDERSTORMS THROUGH THE
EVENING AND OVERNIGHT. THESE STORMS HAVE THE POTENTIAL TO PRODUCE
HEAVY RAINFALL AND SEVERE WEATHER. DRIER AND COOLER WEATHER WILL
SETTLE INTO THE REGION THURSDAY INTO FRIDAY.

&&

.UPDATE...
ISSUED AT 1009 PM EDT WED JUN 12 2013

SVR WIND/LARGE HAIL/ISO TORNADO THREAT INCREASES OVER THE NEXT SEVERAL
HOURS MAINLY SOUTH OF HWY 6 IN INDIANA/OHIO AS LARGE SCALE ASCENT
INCREASES IN ADVANCE OF AN APPROACHING MID LEVEL SHORTWAVE/60 KT
MID LVL SPEED MAX. DEEP LAYER SHEAR AND MLCAPE MORE THAN
SUFFICIENT FOR ROTATING STORMS AND EVENTUAL MCS
MAINTENANCE...ALONG WITH INCREASING LOW LEVEL INFLOW. ANY SVR WX
ACROSS NORTHERN ZONES WILL BE ISOLATED IN NATURE WITH LARGE HAIL
THE PRIMARY THREAT. OTHERWISE...THE GREATEST CHANCE FOR TRAINING
AND FLASH FLOODING WITH THESE CELLS WILL LIKELY BE NEAR THE HWY 30
CORRIDOR IN INDIANA AND OHIO. GRIDS HAVE BEEN UPDATED TO REFLECT
LATEST RADAR/HRRR TRENDS.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 427 PM EDT WED JUN 12 2013

SEVERE STORMS ARE EXPECTED BY EARLY TONIGHT. SEVERAL FACTORS ARE
COMING TOGETHER FOR A SIGNIFICANT OUTBREAK OF SEVERE STORMS AND
POSSIBLE TORNADOES WHICH IS REFLECTED IN THE SPC LATE MORNING
UPGRADE TO A HIGH RISK OVER NEARLY ALL OF THE FCST AREA. A STRONG
CAP WAS JUST BECOMING WEAK ENOUGH UPSTREAM FOR CONVECTION TO FIRE
ACROSS EAST IOWA IN AN INCREASINGLY VERY UNSTABLE AIRMASS.
LINCOLN/ILX 18Z SOUNDING SHOWED THE CAP HAD STRENGTHENED BETWEEN 12Z
AND 18Z...HELPING TO KEEP MOST STORMS AT BAY INTO MID AFTERNOON. SPC
SFC BASED LIFTED INDICIES OF -10 TO -12 WERE ALREADY OVER NRN
INDIANA. BULK SHEAR NEARLY OFF THE CHARTS WITH VALUES OF 55 KTS TO
75 KNOTS. ANOTHER INDICATOR OF THE EXTREME ENVIRONMENT WAS THE SPC
CRAVEN SIG SEVERE PARAMETER ON THE SPC WEB MESO ANALYSIS PAGE WITH
VALUES OF 60K TO OVER 120K WHERE THE SIGNIFICANT SVR THRESHOLD IS
ONLY 20K. SO A POWDER KEG IN THE ATMOSPHERE WAS OVER THE AREA. A SFC
LOW AND UPPER LEVEL TROF WILL MOVE EAST EARLY TONIGHT. EXPECT
EXPLOSIVE STORM DEVELOPMENT AS THE CAP CONTINUES TO ERODE AND THE
STORMS BECOME MORE ORGANIZED. THE ADVECTION OF AN UPSTREAM ELEVATED
LAYER ESPECIALLY 700/500 MB WITH LAPSE RATES APCHG 9C/KM WILL
FURTHER HELP KEEP AN EXTREMELY UNSTABLE AIRMASS OVER THE AREA AHEAD
OF THE STORMS THIS EVENING. LOW LEVEL MOISTURE FLUX WILL INCREASE AS
THE SFC LOW APPROACHES WITH THE UPPER LEVEL SHORT WAVE. HAVE ADDED A
FLASH FLOOD WATCH GIVEN THIS ENVIRONMENT AND PRECIP WATER VALUES
APPROACHING 2.0 INCHES. SOME OF THE AREA WAS STILL TRYING TO DRY OUT
FROM VERY HEAVY RAINS EARLIER IN THE MONTH WITH SOME AREAS RECEIVING
5 TO 6 INCHES OF RAIN. EXPECT THE STORMS TO ORGANIZE IN A SQUALL
LINE WITH WINDS BECOMING DAMAGING ACROSS MUCH OF THE AREA. CURRENT
THINKING IS MOST OF THE SEVERE STORM WILL OCCUR BEFORE
MIDNIGHT...ALTHOUGH HEAVY RAIN POTENTIAL SHOULD CONTINUE THROUGH THE
NIGHT. OTHERWISE...SUBSTANTIAL SUBSIDENCE BEHIND THE UPPER TROF
SHOULD ALLOW SKIES TO CLEAR BY LATE THURSDAY MORNING.

&&

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 427 PM EDT WED JUN 12 2013

FEW CHANGES TO LONG TERM PERIOD WITH FOCUS ON UPCOMING WEATHER EVENT
LATER TODAY.

UPPER LEVEL RIDGING WILL MOVE ACROSS THE AREA AT THE START OF THE
PERIOD...BUT WILL BE SLOWLY DAMPENED INTO THE START OF THE WEEKEND
AS AN UPPER LEVEL TROUGH MOVES ACROSS THE FAR NORTHERN PARTS OF THE
PLAINS.

THE AFOREMENTIONED TROUGH WILL ATTEMPT TO DIG INTO THE NORTHERN
GREAT LAKES WITH TIME THIS WEEKEND. A FRONTAL BOUNDARY WILL STALL
OUT OVER THE REGION FROM LATE SATURDAY INTO AS LATE AS MONDAY WITH
SEVERAL IMPULSES MOVING ALONG IT. THE POTENTIAL EXISTS FOR SEVERAL
ROUNDS OF THUNDERSTORMS TO EITHER DEVELOP OVER AREA OR MOVE IN FROM
THE WEST WITH THE MAIN WINDOW BEING SATURDAY NIGHT INTO SUNDAY.
POTENTIAL FOR BOTH SEVERE WEATHER AND HEAVY RAINFALL MAY
EXIST...ESPECIALLY AS MAIN WAVE ENTERS THE AREA SAT NGT INTO SUNDAY.
FURTHER DETAILS WILL BE ADDED IN LATER FORECASTS AS MODELS HOPEFULLY
COME INTO BETTER AGREEMENT. BY MONDAY NIGHT...DRY CONDITIONS SHOULD
PUSH BACK INTO THE REGION WITH SEASONABLE TEMPERATURES CONTINUING.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING) ISSUED
AT 710 PM EDT WED JUN 12 2013

A CLUSTER OF STORMS WERE DEVELOPING UPSTREAM ALONG A WEAK FRONT
WITH A FRONTOGENETIC SCENARIO GIVEN MARINE BOUNDARY/OLD FRONT TO
THE NORTH/NORTHEAST AND THETA E FLUX INCREASING TO THE SOUTHWEST.
THE APPROACH OF A SHORT WAVE WILL PROVIDE A VOLATILE SITUATION
WITH AN EVENTUAL DERECHO FORMING THIS EVENING. EXPECT WIND GUSTS
AT THE TERMINALS OF 45 TO 55 KNOTS...ALTHOUGH DEPENDING ON QLCS
SYSTEM ORGANIZATION...VELOCITIES COULD EXCEED 70 KNOTS. MORE
STORMS SHOULD CONTINUE TO FORM AS THE SFC LOW APPROACHES. THE
SEVERE WIND THREAT SHOULD DIMINISH BY 06Z...WITH RAIN/STORMS
ENDING BY 14Z AS SUBSIDENCE INCREASES BEHIND THE UPPER LEVEL TROF.

Event by event

8 thunderstorm wind, 6 tornado. Local standard time, as filed.

Tornado, Van Wert

When: June 12, 10:27 PM EST to 10:30 PM EST
Where: Van Wert County, 0.98 mi ESE of Willshire to 1.14 mi NNW of Willshire Osborn Arp
Rating: EF0
Path length: 0.64 mi
Path width: 80 yd
Reported by: NWS Storm Survey
Coordinates: 40.747, -84.802

A circulation touched down on the west side of Willshire, along State Road 81 near the Indiana/Ohio State Line. The tornado traveled southeast down Green Street to the intersection of Green Street and State Route 49. An eyewitness observed the funnel make contact with the ground in his yard, snap off two large trees and continue down the street. The survey revealed additional tree damage along the path. Another eyewitness observed condensation vortices being injected into the funnel as his garage was rolled off its foundation. A portion of a house roof was removed and thrown over a neighbor’s home. A total of 13 homes suffered varying degrees of damage. The circulation was on the ground less than 3 minutes with a maximum width of 80 yards and maximum wind speeds around 85 mph. The same storm continued into Mercer County and later produced another weak tornado.

Thunderstorm Wind, Putnam

When: June 12, 10:49 PM EST to 10:50 PM EST
Where: Putnam County, Continental
Measured: 60 kt (69 mph) estimated gust
Reported by: Emergency Manager
Coordinates: 41.100, -84.270

Emergency management officials reported structural damage around Continental.

Tornado, Henry

When: June 12, 10:55 PM EST to 10:56 PM EST
Where: Henry County, 3.33 mi ESE of New Bavaria to 3.35 mi ESE of New Bavaria
Rating: EF0
Path length: 0.04 mi
Path width: 25 yd
Reported by: NWS Storm Survey
Coordinates: 41.185, -84.109

Eyewitness reports and a National Weather Service Damage survey indicate a circulation quickly formed and touched down on the leading edge of a larger area of downburst winds along County Road Y, west of County Road 12A. The tornado caused some minor roof damage to a residence and snapped or uprooted several trees in the immediate area (DI: TH DOD: 3); some debarking of tree tops was observed. Wet ground likely aided uprooting of trees. Shortly after touchdown, the tornado became outflow dominant and quickly dissipated with debris being carried by straight line winds to the east. Maximum path length was 50 yards with a maximum width of 25 yards. Wind speeds were estimated at around 85 mph.

Tornado, Henry

When: June 12, 10:59 PM EST to 11:01 PM EST
Where: Henry County, 1.09 mi NNW of Hamler to 1.21 mi N of Hamler
Rating: EF1
Path length: 0.43 mi
Path width: 50 yd
Reported by: NWS Storm Survey
Coordinates: 41.245, -84.036

A NWS survey of damage north of Hamler indicated a circulation quickly intensified and touched down onto a barn, destroying it and throwing the debris to the northeast for nearly a half mile (DI: SBO DI: 6). Several large trees in the immediate area were snapped. An adjacent soybean field indicated a convergent wind pattern which continued towards a small grove of trees where the tornado dissipated. The maximum width was 50 yards with maximum wind speeds estimated at 95 mph.

Thunderstorm Wind, Henry

When: June 12, 10:59 PM EST to 11:00 PM EST
Where: Henry County, 1.68 mi NNE of Hamler
Measured: 70 kt (81 mph) estimated gust
Reported by: NWS Storm Survey
Coordinates: 41.252, -84.016

A NWS storm survey of damage at a farm indicated a combination of the remnant circulation of a tornado to the southwest of the site, as well as an anchoring failure, resulted in the collapse of a grain leg collapse and damage to several empty grain bins. The grain leg was anchored by a three point system, with the northeast side of the leg being unanchored. As the strong winds impacted an anchor on the southwest side, the leg began to buckle and shift, causing the bending of a large I-beam and the uplift of a cement block where an anchor was set to the northwest of the leg. The grain leg twisted and collapsed onto several bins. Given the failure of the anchoring, winds are estimated at around 80 mph.

Thunderstorm Wind, Henry

When: June 12, 10:59 PM EST to 11:00 PM EST
Where: Henry County, Hamler
Measured: 61 kt (70 mph) estimated gust
Reported by: NWS Storm Survey
Coordinates: 41.230, -84.030

Widespread tree and tree limb damage was noted in and around the town of Hamler by NWS officials while conducting surveys of tornado damage in the area. All damage within the town of Hamler was the result of straight line winds.

Thunderstorm Wind, Putnam

When: June 12, 11:00 PM EST to 11:01 PM EST
Where: Putnam County, North Creek
Measured: 60 kt (69 mph) estimated gust
Injuries: 1 direct, 0 indirect
Reported by: Law Enforcement
Coordinates: 41.150, -84.220

Law enforcement officials reported numerous trees and power lines down from North Creek to Leipsic. A mobile home was overturned on the south side of North Creek, with one person suffering minor injuries.

Tornado, Henry

When: June 12, 11:02 PM EST to 11:03 PM EST
Where: Henry County, 1.99 mi SE of Malinta to 2.01 mi SE of Malinta
Rating: EF1
Path length: 0.17 mi
Path width: 75 yd
Reported by: NWS Storm Survey
Coordinates: 41.298, -84.006

A NWS Storm survey indicated that a circulation rapidly touched down at a residence on the south side of County Road J. A detached garage suffered extensive damage, as well as an adjacent barn suffering total loss of its roof (DI: SBO, DOD: 4). The tornado continued northeast with debris from the residence impacting a two story home, causing the destruction of a porch, as well as a large hole punched into the west side of the upper story of the house (DI: FR12, DOD: 4). A large pine tree had the top half snapped off and then thrown roughly 50 feet to rest against other trees on the property. The tornado continued across a field into a small grove of trees, where the tornado likely became outflow dominant and dissipated. While damage to the second residence could indicate much stronger wind speeds, a maximum wind speed of 95 mph was estimated due to the impacts of larger debris from the point of touchdown. The maximum width of the tornado was around 75 yards.

Thunderstorm Wind, Henry

When: June 12, 11:02 PM EST to 11:03 PM EST
Where: Henry County, 1.94 mi S of Grelton
Measured: 70 kt (81 mph) estimated gust
Reported by: NWS Storm Survey
Coordinates: 41.302, -83.999

Several power poles were observed broken or pushed down along County Road 7, north of County Road J.

Tornado, Henry

When: June 12, 11:03 PM EST to 11:04 PM EST
Where: Henry County, 1.85 mi W of Mc Clure Arpt to 1.79 mi W of Mc Clure Arpt
Rating: EF0
Path length: 0.11 mi
Path width: 15 yd
Reported by: NWS Storm Survey
Coordinates: 41.298, -83.986

A NWS Storm survey of damage indicated that two weak and brief tornado occurred, separated by a quarter mile. A convergent, variable track pattern was noted in a wheat field. While the wheat was laid down, actual damage was minimal. The maximum width was 15 yards, with maximum winds of 70 mph.

Tornado, Henry

When: June 12, 11:03 PM EST to 11:04 PM EST
Where: Henry County, 2.06 mi S of Grelton to 1.9 mi SSE of Grelton
Rating: EF0
Path length: 0.25 mi
Path width: 15 yd
Reported by: NWS Storm Survey
Coordinates: 41.301, -83.992

A NWS Storm survey of damage indicated that two weak and brief tornado occurred within a quarter mile of each other. One of these touchdowns caused the collapse of barn doors as well as one of the walls to be blown out. Corn in an adjacent field indicated a brief convergent pattern. The maximum width was 15 yards with a maximum wind speed of 70 mph.

Thunderstorm Wind, Henry

When: June 12, 11:04 PM EST to 11:05 PM EST
Where: Henry County, 2.65 mi S of Westhope
Measured: 65 kt (75 mph) estimated gust
Reported by: Emergency Manager
Coordinates: 41.262, -83.921
