The episode as NWS CLE wrote it up.
Northern Ohio resided in the warm sector during the late morning through early evening of the 29th as a surface cold front approached slowly from the Upper Midwest and western Great Lakes. Simultaneously, the parent surface low drifted eastward from northeastern Manitoba into far-northern Ontario. The warm sector consisted of moderate to strong MUCAPE, moderate effective bulk shear, and primarily moderate to strong DCAPE in northern Ohio. As a squall line evolved generally eastward across northeast Ohio, it generated very isolated straight-line wind damage in Mahoning County during the early afternoon of the 29th. Later that day, a separate and outflow-dominant squall line generated scattered straight-line wind damage in northern Ohio as the squall line evolved generally eastward. A thunderstorm ahead of this squall line managed to produce a downburst in Medina County.
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 Cleveland, OH wrote its last area forecast discussion before the first event at Aug 29, 8:55 AM EST, 3 hours 11 minutes earlier.
Area Forecast Discussion National Weather Service Cleveland OH 955 AM EDT Mon Aug 29 2022 .SYNOPSIS... Showers and storms ahead of a series of cold fronts, the first coming through late tonight and early Tuesday, one later Tuesday evening, and then the last one Wednesday night. Dominant high pressure Thursday through the weekend. && .NEAR TERM /THROUGH TUESDAY/... Quite a challenging forecast for the next 18 hours or so with several rounds of convection possible through tonight. High res guidance does not have a good handle on convection that is spreading east across the area, but adjusted PoPs based on current radar trends and the few guidance members that had at least a slight handle on the current setup. There will likely be a lull in precip behind the initial round, with additional convection possibly blossoming this afternoon given the instability and moisture along with any boundaries left behind by morning convection. The highest PoPs are still after 00Z as a weakening MCS moves southeast towards the CWA - even then, some guidance members portray the MCS diving south to the west of the area or weakening with very little eastward progression. Reduced Pops slightly to account for this uncertainty and spread in guidance, but may need to increase precip chances once more if models begin to align later this morning and this afternoon. Any convection will rely heavily on mesoscale features. Nonetheless, instability still warrants at least a marginal threat of severe weather with damaging wind gusts and heavy rain being the primary threats. Original Discussion... Currently watching a complex of storms evolve and cycle over central Indiana with a north northeastward track towards the western zones of the CWA. CAMs indicating that this should be on the wane as it reaches the CWA over the next 3-6 hours despite a lobe of higher 850mb wind working into the area, and will be watching IR satellite imagery for signs of cloud top warming going forward. Southwest flow aloft becomes active ahead of the cold front approaching from the west. Low shear environment with the better dynamics further to the northwest, but enough instability and mid level dryness to give the region a wind threat. Dewpoints have crept up into the high 60s in the western zones to near 70F, and should continue to climb a couple more through the day. The real challenge of the forecast comes from timing the waves of convection rolling through without plastering the CWA with POPs until the cold front passes later tonight into Tuesday morning. Feel the ARW and Nest has a decent handle on it, but still show some differing solutions heading into tonight. Continued warm in the warm sector with a couple 90 degree readings possible, signaling that the waves of convection could be spelled by brief clearing and enough insolation that the max temperatures may not be affected by the activity. POPs on the wane after the first cold front passage, and should get another weaker one later in the day. But the fact that the first will not be a complete airmass changer, POPs will be much slower to exit as we wait for the significantly cooler and drier air to filter in. That said, will lose 6-10 degrees off the high temperature from the Monday readings. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... The cold front will push east away from the area Tuesday night, as a large scale upper low spins over Hudson Bay and surface ridging works east into the area. A secondary trough will rotate southeast through the lower Great Lakes before the ridge axis overspreads the area from the west Thursday and settles east of the area by Thursday night. Some lingering lake enhanced showers will be possible across the primary snowbelt of northeast OH and northwest PA Tuesday night into Wednesday before drying out. Another uptick in shower activity is possible with the secondary trough moving through Wednesday night, but dry conditions are then expected Thursday/Thursday night. Outside of far northeast OH/northwest PA, dry conditions are expected through the period. A brief cool down is expected Wednesday into Thursday with the trough moving through. By Thursday, highs will range from the upper 60s in northwest PA to the low/mid 70s elsewhere. Wednesday night and Thursday night will see lows in the low to mid 50s away from the lake and upper 50s to near 60 near the lake, with some outlying areas/typical cool spots dropping into the upper 40s Thursday night. && .LONG TERM /FRIDAY THROUGH SUNDAY/... Models in good agreement on the overall pattern evolution and local area impacts this weekend, as ridging becoming entrenched across the eastern CONUS. A longwave trough will try to settle southeast from central Canada into the Great Lakes Saturday into Sunday, but a stout Mid Atlantic-centered ridge will continue to influence the local area. Models try to bring a weakening front into the region from the north Sunday, with the upper pattern flattening to zonal flow. Have maintained a dry forecast for now on Sunday with overall weak forcing , but this may be the next appreciable chance for precip beyond the middle part of this week. && .AVIATION /12Z Monday THROUGH Friday/... Low confidence aviation forecast with convective chances off and on through the day. The challenge has been timing these features, and continue to use PROB30 to nail down the best windows of opportunity for TSRA, but this proving to be difficult, and even more so now with overnight convection that is reworking the atmosphere in NW OH. It should be expected that there will be windows of time free of convection, and AMDs are likely to accommodate ongoing and evolving thunderstorms. Some wind gusts will be possible in storms as already seen at FDY and 31kts. Outlook...Scattered showers/thunderstorms with non-VFR possible Tuesday. && .MARINE... Southwest winds will ramp up through the day as a warm front lifts northeast across the lake, with winds in the 10 to 20 kt range. Winds will slowly veer southwesterly late tonight and westerly into Tuesday before a strong cold front moves across the lake. Winds will become northwest 15-20 kts behind the front into Tuesday night which will likely necessitate a Small Craft Advisory for a good portion of the lake. Winds back southwesterly late Wednesday ahead of a secondary trough/cold front, which will cross the lake Wednesday night and bringing northerly flow in its wake. Lighter winds are expected Thursday as high pressure builds across the lake, with winds becoming southerly and increasing slightly into the weekend with the ridge axis shifting east.. && .CLE WATCHES/WARNINGS/ADVISORIES...
