The episode as NWS CLE wrote it up.
A mid/upper-level trough lingered over the Great Lakes and Middle to Upper OH Valley during the afternoon of the 23rd through early evening of the 25th as embedded shortwave disturbances traversed northern OH generally from west to east. Multiple surface trough axes associated with the disturbances moved generally eastward across northern OH. Low-level convergence and associated ascent along surface trough axes acted as a focus for scattered thunderstorm development during the early evening of the 23rd. These multicell thunderstorms generated isolated straight-line convective wind damage as they persisted northeastward and encountered moderate MUCAPE and marginally-moderate effective bulk shear. Low-level convergence and associated ascent along a Lake Erie lake breeze front generated scattered thunderstorms in the Cleveland metro area during the afternoon of the 25th. The pulse thunderstorms produced isolated severe hail and straight-line convective wind damage as they persisted generally southward and encountered strong MUCAPE and weak to marginally-moderate effective bulk shear.

Area Forecast Discussion National Weather Service Cleveland OH 406 PM EDT Sun Jul 23 2023 .SYNOPSIS... An upper trough will move east across the area this evening before surface high pressure builds into the area later tonight. Surface high pressure will linger over the area through the week with a few shortwave troughs moving over the region. && .NEAR TERM /THROUGH MONDAY NIGHT/... Scattered convection continues to persist across the region, mainly across northwest Ohio and along the Lake Erie shore in northeast Ohio. Some of the cells over the past two hours have pulsed up to appreciable levels to produce some gusty winds and perhaps some hail. Around 1000 j/kg MLCAPE currently present across the area with steep low level lapse rates allowing for quick developing/short duration convection. Overall, storms are not expected to be strong to severe given the lack of deep layer bulk shear marginal mid level lapse rates. Coverage should expand a bit eastward over the next several hours as an upper shortwave works east towards the lower Great Lakes. Instability is expected to weaken diurnally this evening and would expect shower/storm coverage to diminish aside from some lingering shower activity coincident with the vort max moving over the region tonight. Broad upper troughing will remain over the region tonight through Monday night with some weak surface high pressure building into the area. Some diurnally driven convection possible on Monday, but the better support for convection may remain south of the area. Went with slight chance/low chance pops similar to the previous forecast. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... Cyclonic W'erly to NW'erly mid/upper-level flow and embedded shortwave disturbances are expected to impact our CWA during this period. At the surface, we should be located along the northern flank of a high pressure ridge centered in vicinity of the southern Appalachians. Simultaneously, multiple and subtle surface trough axes should accompany the shortwave disturbances and traverse our region generally from west to east. Net low-level warm and moist air advection from the Gulf of Mexico will contribute to a warming trend in our CWA as humidity increases. Sufficient daytime heating of surrounding land and a relatively-weak synoptic MSLP gradient should allow a lake breeze to occur within about five miles of all of Lake Erie during the late morning through early evening hours on Tuesday and within about five miles of the lake from northeastern Cuyahoga County to Erie County, PA during the late morning through early evening on Wednesday. Overnight lows should reach mainly the 60's around daybreak Wednesday morning and mainly the mid 60's to lower 70's around daybreak Thursday morning. Late afternoon highs should reach the 80's to 90F on Tuesday and the mid 80's to lower 90's on Wednesday. The coolest highs are expected within the lake breeze. Of note, normal lows are in the lower to mid 60's and normal highs are in the lower to mid 80's this time of year. Isolated to scattered and periodic rain showers/thunderstorms are possible, especially during the afternoon through early evening hours of the short-term period, since daytime heating of the humid boundary layer should yield moderate to perhaps strong CAPE and non-excessive CIN for parcels rooted in that layer. Low-level convergence and associated ascent along the expected lake breeze front and surface trough axes should act as a focus for shower/storm formation. However, odds favor fair weather on Tuesday when the stabilizing surface ridge may exert greater influence in our CWA. && .LONG TERM /THURSDAY THROUGH SUNDAY/... W'erly to NW'erly mid/upper-level flow is expected to remain cyclonic over our CWA during the long-term period. Additional shortwave disturbances embedded in the flow aloft are forecast to impact our region. At the surface, a high pressure ridge is expected to remain centered near the southern Appalachians and influence our region before a cold front drifts SE'ward across our CWA on Friday and/or Saturday. Another high pressure ridge should build from the Canadian Prairies and north-central United States behind the front. However, subtle surface trough axes accompanying the shortwave disturbances will continue to move generally E'ward through our region. Periodic and isolated to scattered showers/thunderstorms remain possible amidst sufficient atmospheric moisture and instability, especially on Friday into Saturday with the approach and eventual passage of the cold front. Continued low-level warm and moist air advection ahead of the cold front will contribute to unusual warmth and continued increase in humidity on Thursday through Friday. Late afternoon highs are forecast to reach mainly the lower to mid 90's on both days. Overnight lows should reach only the lower to mid 70's in most locations around daybreak Friday morning. Somewhat cooler readings are expected Friday night through Sunday due to low-level CAA behind the eventual cold front passage, fairly abundant cloud cover, and the wet-bulb effect associated with periodic precip. Overnight lows should reach mainly the 60's around daybreak on Saturday and Sunday mornings. Daily highs should reach mainly the upper 70's to mid 80's this upcoming weekend. && .AVIATION /18Z Sunday THROUGH Friday/... Mainly VFR conditions through the period with the primary focus being iso/sct SHRA/TSRA ongoing across northwest OH at the onset of this period. Coverage will be fairly scattered with limited lightning, with only enough confidence for TEMPO TSRA mentions at KTOL/KFDY for a few hours early in the period. A brief MVFR/IFR reduction cannot be ruled out with any storm that impacts a terminal. Otherwise, some VCTS mentions at KMFD/KCLE through 00Z where more uncertainty/confidence in thunder resides. SHRA/TSRA activity should wane after 00Z, with VFR expected through the end of the period. Southwest winds will become light overnight, increasing again out of the west near the end of the period. Northwest winds possible with a brief lake breeze early in the period at KERI. Outlook...Non-VFR possible in isolated to scattered afternoon/evening showers and thunderstorms Monday through Thursday. The highest chance for showers and thunderstorms appears to be late Tuesday evening and overnight. && .MARINE... Primarily southerly to southwesterly winds around 5 to 15 knots are expected through Friday as a ridge lingers over Lake Erie and the parent high pressure center moves from near the Lower MS Valley toward the southern Appalachians. However, a daily lake breeze should impact all nearshore zones during the late morning through early evening hours on Monday and Tuesday, and nearshore zones from roughly Cleveland to Ripley on Wednesday. Waves trend mainly 3 feet or less. Occasional 4 footers are possible on Friday when predominantly southwesterly winds may freshen toward 20 knots and a cold front approaches the lake from the northwest. && .CLE WATCHES/WARNINGS/ADVISORIES...
