The episode as NWS IWX wrote it up.
The edge of strong high pressure was situated over northwestern Ohio as a series of disturbances moved into the region. In addition, the remnants of a tropical system added to already abundant moisture to set the stage for isolated severe storms and several rounds of torrential rainfall for parts of northwestern Ohio. Rainfall rates of two to three inches per hour were common with the stronger cells, allowing 5 day rain totals in some areas to exceed eight inches. Widespread high water was reported in several counties, with the town of Kalida being cut off for a period of time as several creeks and rivers all exceeded their banks at the same time, closing all roads into the town.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
354 PM EDT MON JUN 15 2015
.SYNOPSIS...
ISSUED AT 348 PM EDT MON JUN 15 2015
A COLD FRONT OVER WISCONSIN IS EXPECTED TO MOVE SOUTHEAST ACROSS
THE AREA TONIGHT CAUSING SHOWERS AND THUNDERSTORMS WITH HEAVY
RAINFALL ACROSS THE AREA TONIGHT. THE FRONT WILL STALL OVER
CENTRAL INDIANA TUESDAY... CONFINING THE CHANCE OF SHOWERS TO
SOUTHERN PORTIONS OF OUR AREA AND THEN LIFT BACK NORTH ON
WEDNESDAY BRINGING MORE WIDESPREAD RAIN BACK TO THE AREA. LOWS
TONIGHT WILL BE IN THE MID TO UPPER 60S... WITH HIGHS ON TUESDAY
IN THE LOWER TO MIDDLE 80S.
&&
.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 348 PM EDT MON JUN 15 2015
FRONTAL BOUNDARY WHICH HAS BEEN STNRY FOR SOME TIME TO OUR NORTH
WAS BEGINNING TO MAKE SEWD PROGRESS TODAY IN RESPONSE TO A SHRTWV
MOVG ACROSS ONTARIO MERGING WITH SECOND SYSTEM LIFTING NE FROM THE
CENTRAL PLAINS. VERY MOIST AIRMASS IN PLACE OVER THE AREA WITH
PWATS AROUND 2" HAS DESTABILIZED IN THE WARM SECTOR TODAY ALLOWING
NUMEROUS TSTMS TO DEVELOP. SOME BACKBUILDING/TRAINING CELLS OCRG
ATTM AS SUGGESTED BY RAP 5-10KT UPWIND PROPAGATION VECTORS. LATEST
HRRR SUGGESTS SCT-NUMEROUS STORMS WILL CONT LATE THIS AFTN AHEAD
OF THE FRONT WITH MORE WIDESPREAD TSTMS FORMING ALONG THE FRONT
LATE THIS AFTN AND MOVG THROUGH OUR AREA OVERNIGHT. THUS... STILL
APPEARS TO BE A GOOD SETUP FOR EXCESSIVE RAINFALL ACROSS OUR AREA
SO FFA ISSUED EARLIER TODAY WILL CONT THROUGH LATE TONIGHT.
CDFNT EXPECTED TO MOVE INTO CENTRAL INDIANA BEFORE STALLING OUT ON
TUE. SOME LINGERING POST-FRONTAL SHOWERS PSBL IN THE MORNING AND WK
INSTABILITY MAY ALLOW A FEW MORE TO DEVELOP IN THE AFTN... BUT
OVERALL APPEARS TO BE A DAY TO DRY OUT.
WK CAA BEHIND THE FRONT SHOULD ALLOW TEMPS TO DROP INTO THE 60S
TONIGHT WITH MORE SUNSHINE AND DRY CONDITIONS ALLOWING HIGHS TO
REACH THE L-M80S ON TUE.
&&
.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 348 PM EDT MON JUN 15 2015
WET PATTERN AND FLOODING CONCERNS WILL CONTINUE INTO THE LONG
TERM PERIOD AS A CONSISTENT SUBTROPICAL MOISTURE FEED PUMPS PWAT
VALUES AOA 2.0" INTO THE CWA. ONLY DAY OF RELIEF IN THE LONG TERM
PERIOD MAY BE FRIDAY AS A HIGH PRESSURE CENTER SLIDES THROUGH THE
GREAT LAKES AND TRIES TO SLIDE OUR PESKY FRONTAL BOUNDARY
SOUTHWARD. SOME PRECIP IS STILL POSSIBLE NORTH OF THIS BOUNDARY ON
FRIDAY...BUT THE HIGHLY EFFICIENT WARM CLOUD PROCESSES WILL CEASE
NORTH OF THE FRONT. THE REMNANTS OF THE TROPICAL SYSTEM CURRENTLY
IN THE WESTERN GULF ADVECT INTO THE AREA OVER THE WEEKEND AND
RETURN THE MUGGY CONDITIONS TO THE SOUTHERN LAKES. BOTH THE GFS
AND ECMWF INDICATE THE TROPICAL SYSTEM MAY PHASE WITH A NORTHERN
STREAM WAVE AND DEVELOP A SUB 1000MB SURFACE REFLECTION IN THE
VICINITY OF THE GREAT LAKES. A DECENT WAVE MOVING THROUGH THE
GREAT LAKES MAY BE JUST WHAT WE NEED TO FINALLY SHUNT THIS FRONTAL
BOUNDARY WELL SOUTH OF OUR AREA AND USHER IN DRIER CONDITIONS.

MCDThe Northern Indiana radar (KIWX), 78 km away, was scanning. The volume nearest the first event began at 20:01 UTC.
4 thunderstorm wind, 4 flood, 2 flash flood. Local standard time, as filed.
Trained spotters reported several tree limbs roughly one foot in diameter blown down. Smaller branches were also noted blown down.
A trained spotter reported several eight to ten inch diameter tree limbs were blown down.
While overall rainfall amounts were not as significant as counties to the south of Putnam county, river and creek levels increased across mainly the southern portion of the county, causing several road closures due to high water. The most significant flooding occurred in the Kalida area, with a separate entry under Flash Flood outlining the details.
High water impacted many county and state routes at one point or another during the duration of the flood event. The Saint Marys river well exceeded its banks, especially in the town of Willshire, where flood waters impacted parts of the town for several days. Five to locally as much as eight inches of rain fell over mainly southern parts of the county onto already saturated ground.
While overall rainfall amounts were not as widespread as other adjacent counties, what rain did fall only added to rising river and creek levels from upstream rainfall. Numerous township, county and state roads were impacted by high water, forcing high water signage or in some cases closures. No rescues or property damage was reported. Damage estimates for any roads was not available.
At the peak of the event, several dozen roads were partially or completely impassable from flowing or standing water as runoff from the heavy rain overwhelmed local streams, creeks and rivers. Portions of several State routes were closed for an extended period of time with 6 to 12 inches of water flowing over them.
Torrential rainfall fell well south of the county across much of Allen county, Ohio which ran off into the Ottawa River. The runoff from this rainfall rapidly moved upstream into the county and caused a rapid increase in river and creek levels around the town of Kalida. High water impacted nearly the entire town, with some locations seeing several feet of flood water closer to the river edges. Of greater significance was that the high water levels caused flood waters to cover all of the state and U.S. routes that intersect within the town limits. This essentially cut the town off from the surrounding communities due to a combination of the high water on the road and travel of vehicles through the water causing wave action which increased local flooding issues.
Water rescue was needed on Piquad Road, between State Route 309 and Wapakoneta Road as the Ottawa River flooded the roadway. An unofficial report of 6.8 inches of rain was recorded since Friday afternoon.
A trained spotter estimated 50 to 60 mph wind gusts for at least 15 minutes.
Emergency management officials reported four power poles were snapped at the intersection of Flory and Independence Roads.
