The episode as NWS CLE wrote it up.
A warm frontal boundary containing very moist air and dew points near 70 degrees lifted north across Ohio during the evening of June 4. Several mini-supercells developed and moved north from central Ohio producing little if any lightning. One of these storms produced a downburst in Wayne County southeast of Reedsburg. This downburst contained 80 to 90 mph winds and ripped off an extensive section of a barn roof. Minor damage to the roofs and walls of other buildings on the property was also sustained. Several power lines and poles were brought down by the storm.

NWS Cleveland, OH wrote its last area forecast discussion before the first event at Jun 4, 7:46 PM EST, 35 minutes earlier.
Area Forecast Discussion National Weather Service Cleveland OH 846 PM EDT SAT JUN 4 2016 .SYNOPSIS... Low pressure over the lower Ohio Vally will move north across the Great Lakes tonight. A cold front over the midwest will move east and cross the area Sunday morning. A trough of low pressure will drop across the lower Great Lakes on Monday. A deep trough aloft will linger over the eastern Great Lakes into mid week. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Not much instability to work with this evening with only 500 J/kg of ML CAPE just clipping our southern counties. Psuedo warm front with dewpoints approaching 70 degrees is also located in this area and storms in the south have been rotating amidst the broad sheer. These storms have otherwise just been producing heavy rain but will continue to monitor for any stronger rotation. LCL's are also low near 500 meters. Elsewhere have dropped back to just a slight chance of thunderstorms for tonight with most areas receiving some rain. Previous discussion... Plume of moisture and upward motion spreading northeast from the upper low in Texas will spread showers and embedded thunder across northwest Ohio. A second area of showers and thunderstorms will fill in across the mid Ohio Valley where it is getting unstable under the increasing low and mid level wind field as the jet expands northward into the area. The feeling here is that the severe threat should slide southeast of the forecast area based on the current mesomodel capes and shear although cannot rule out a strong storm or two in the southeast counties. There will be enough support aloft that showers and scattered thunderstorms will spread across the entire forecast area by early evening. The weakening cold front over the Mississippi Valley will continue east and will also provide additional upward motion later tonight as it gets into the forecast area. Difficult to tell where the front will be Sunday morning, perhaps I-71 by 12Z? The threat of showers will taper off with frontal passage. Lows tonight will be dictated mainly by the dew points, which will rise into the 60s with the showers and probably not drop off too much by daybreak except perhaps around the I-75 corridor. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/... All of the model show a surface trough dropping across the lower Great Lakes as the upper trough also moves east on Sunday. New showers and thunderstorms will develop. Not sure how fast... probably in the afternoon with the heating of the day and the surface trough. With the steepening lapse rates as it gets colder aloft there will almost certainly be thunder and cannot rule out the risk of severe storms. The limiting factor will be the amount of cloudiness that develops and amount of cape. Not a big enough risk at the moment to specifically high light it in the forecast. The trough aloft will wobble over the Great Lakes through the early part of the week with short waves dropping through the trough. Kind of tough to time each wave too far in advance. It looks like Monday could be between waves although it will be troughy enough for a small chance of showers. Highs Monday should still sneak into the mid 70s for most of the area. The next short wave may arrive Monday night but there tends to be less activity at night and will not forecast anything more than a chance/slight chance. && .LONG TERM /TUESDAY THROUGH SATURDAY/... The long term forecast begins with a large upper level trough set up over eastern Canada. This trough will extend a pair of shortwave troughs that will move through the area on Tuesday and Wednesday. These troughs will present nothing exciting except for some slight chance to chance pops for both days and temperatures a couple degrees below average. Some precipitation could linger on Wednesday in the snow belt region before completely drying out on Thursday. For Thursday through Saturday, the large trough over Canada will have only meandered eastward to the Canadian Maritimes, thus putting the region on the backside and in northwest flow aloft. The extended models are beginning to hint at a bit of ridging trying to develop for Thursday along with high pressure at the surface, allowing for at least one dry day in the long term and temperatures recovering a bit towards climatology. However, it looks as if there could be a chance for more showers and thunderstorms on Friday and Saturday in the NW flow pattern aloft. && .AVIATION /00Z Sunday THROUGH Thursday/... A line of light to moderate rain is just now moving into the Toledo and Findlay areas. This line will continue to push east across northern Ohio tonight ahead of a cold front. MVFR and brief IFR possible with the heavier showers. The most persistent showers will clear KERI by 10Z. Expecting MVFR CIGS to linger throught the overnight before drier air works in behind the front. The front will be getting into NWOH by 12Z, not clearing KERI until around 18Z. Expect wind to increase with and behind the front. Gusts could be as high as 25 knots, at times, across NWOH especially. Outlook...Areas of non-VFR Sunday in showers/thunderstorms. Non VFR possible Sunday night through Tuesday. && .MARINE... A warm front over central Ohio will move northward tonight, ahead of a developing area of low pressure over the western Great Lakes. Thus, easterly winds over Lake Erie will shift around to the south on Sunday morning and increase on Sunday afternoon. The developing low pressure system will move eastward on Sunday and deepen before moving northeast into Canada on Monday. With the departing low, winds on Lake Erie will shift from the south to the west and increase to 15 to 25 knots as colder air arrives. Waves will then build to 3 to 5 feet late Sunday into Monday with these west winds and a small craft advisory will probably be needed. Winds will generally decrease Monday night into Tuesday, but 10 to 20 knot winds from the west to northwest should continue through mid week. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None.
