The episode as NWS CLE wrote it up.
At the surface, a cold front drifted southeastward from the Upper MS River Valley to far-southwestern ON, far-western Lake Erie, and northwest OH between the early afternoon of the 23rd and late morning of the 24th as a low moved east-northeastward from central Lake Michigan to Georgian Bay. The cold front then advanced farther southeastward to eastern Lake Erie, northwest PA, and northeast OH by the early evening of the 24th as the low moved northeastward to southwestern QC. This cold front encountered a warm and humid sector along the northwestern flank of the Bermuda-Azores subtropical high pressure ridge. Along and ahead of the cold front, several rounds of multicell thunderstorms impacted northeast OH and generated damaging straight-line convective wind gusts. These storms occurred in an environment comprised of moderate effective bulk shear, MUCAPE, and DCAPE, respectively.
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 Jul 23, 12:42 PM EST, 2 hours 10 minutes earlier.
Area Forecast Discussion National Weather Service Cleveland OH 142 PM EDT Tue Jul 23 2024 .SYNOPSIS... Continued rain chances through mid-week under weak disturbances. A cold front will cross southeast Wednesday night into Thursday. High pressure builds overhead behind the front Friday and persists into the weekend. && .NEAR TERM /THROUGH WEDNESDAY/... 1:42 PM EDT Update... Forecast remains valid per latest trends in obs and model guidance. Isolated to scattered showers/thunderstorms amidst moderate effective bulk shear have developed since late this morning along the following lifting mechanisms: Ongoing lake breeze front, surface trough axis accompanying the shortwave trough mentioned in previous discussion, and mesoscale fronts stemming from differential diurnal heating. Expect this multicellular convection to persist through this early evening before likely dissipating thereafter as the boundary layer stabilizes via nocturnal cooling. The environment remains favorable for strong convective wind gusts. Please see discussion below for further details. Previous Discussion... Upper level trough remains situated over the Great Lakes region keeping unsettled weather in place through the near term period. Today will start off dry before a shortwave moving along the base of the upper trough enters this afternoon. This will kick off the development scattered showers and isolated thunderstorms mainly along a line from Mansfield-Cleveland-Erie and points south. Daytime heating will allow for MLCAPE values to rise into the 500-1000 J/kg range with roughly 600-800 J/kg of DCAPE and steep low level lapse rates. The threat for any "severe" storms remains low but a few stronger cells may be capable of producing strong wind gusts this afternoon and early evening. Showers and storms will diminish in coverage and intensity later this evening from west to east. We'll see a window of dry weather tonight and early Wednesday before the upper trough axis moves overhead through the day Wednesday. At the surface, low pressure over Quebec will drag a cold front southeast across northern Ohio Wednesday evening. Showers and thunderstorms along and ahead of the cold front will enter a favorable environment for strong to severe storms as daytime heating will lead to MLCAPE values to rise into the 1000-1500 J/kg range. Modest instability will be accompanied by 25-30 knots of 0-6 km bulk shear and steepening low level lapse rates. As such, SPC has placed our entire area and the eastern Great Lakes region in a Marginal Risk (Level 1/5) for Severe Weather in their Day 2 Convective Outlook with a primary hazard of damaging wind gusts. High temperatures each afternoon will rise into the low to mid 80s with overnight lows settling in the mid 60s Tuesday night. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/... By the time Wednesday night rolls in, cold front will be tracking through the CWA and continuing what looks to be the best chance for organized rainfall for the area. Once the cold front passes through, there will be a lag for the upper level trough axis swinging through the Great Lakes, with patchy PVA aloft, cooler low/mid level temperatures, and enough lingering layer moisture for post frontal showers. Column should dry out by 18Z Thursday, lastly in the far southeastern zones of the CWA, and forecast turns dry after that as high pressure builds into the lakes. Temperatures drop 5-8 degrees for Thursday and Friday from the Wednesday prefrontal values, and dewpoints by Friday will have dropped around 10 degrees. && .LONG TERM /SATURDAY THROUGH TUESDAY/... High pressure will slowly shift from the Great Lakes eastward off the mid Atlantic coast in the long term forecast period. This will translate to a gradual warming trend as the CWA gets into return southerly flow while upper level high pressure builds over the deep south region. Column remains on the dry side through at least the Sunday time frame, with low/mid level moisture making a comeback for the beginning of next work week, and thus a return of POPs. By then, could also see temperatures solidly in the upper 80s to around 90F for most places from Sunday onward, with dewpoints back into the 60s by this time as well. && .AVIATION /18Z Tuesday THROUGH Sunday/... Mainly VFR expected through 18Z/Wed as cyclonic WSW'erly to W'erly flow aloft and embedded disturbances affect our region. Simultaneously and at the surface, a weak trough lingers over/near the eastern Great Lakes and Upper OH Valley as a SE'ward-moving cold front approaches from the central Great Lakes and Upper MS Valley. Our regional surface winds are expected to be mainly SW'erly to W'erly around 5 to 10 knots. However, a lake breeze persists over Lake Erie and within several miles of the lake through ~00Z/Wed and will impact KERI and eventually KCLE. Scattered showers/thunderstorms persist through this early evening due, in part to the passage of the aforementioned disturbances aloft and attendant surface trough axes. Additional isolated showers/thunderstorms are possible during the rest of the TAF period, especially after 15Z/Wed. Brief MVFR/IFR and brief/erratic surface gusts up to 40 knots are possible with showers/storms. Outlook...Isolated to scattered showers/thunderstorms with non- VFR expected Wednesday afternoon through Thursday. Isolated showers/thunderstorms with non-VFR possible Sunday afternoon and evening. && .MARINE... Variable winds under 10kts become southwesterly tonight and Wednesday ahead of a cold front, increasing to 10-15kts by Wednesday afternoon. As the cold front moves through, winds then turn northwesterly 10-15kts and wave heights build to 1-3ft for the central and eastern basins of Lake Erie. With high pressure moving in for the end of the week, winds turn northeasterly 5-10kts Friday and Saturday with wave heights 1-2ft. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None.
