424 FXUS61 KCLE 242326 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 726 PM EDT Fri Jul 24 2026 .WHAT HAS CHANGED... No significant changes to the previous forecast. && .KEY MESSAGES... 1) Mostly dry conditions expected through Saturday with patchy dense fog possible overnight. 2) A series of troughs will traverse the region beginning on Sunday, bringing multiple rounds of showers and storms to the area through mid next week. Some storms may be strong to severe with the greatest chance of severe weather on Monday. && .DISCUSSION... KEY MESSAGE 1... As high pressure remains dominant over the area, the majority of the area should remain dry through Saturday. The exception to this may be across counties east of I-77 on Saturday as increased moisture pushes north over an area of weak isentropic lift. Any showers that do develop should remain light and short lived given weak forcing and the thunder potential remains minimal. Highs on Saturday will be a bit warmer, climbing into the low to mid 80s. During the overnight period tonight and Saturday night, patchy fog is possible especially south of US-30 where low level moisture will increase under an inversion. Confidence in the extent or density remains low due to some lingering clouds possible tonight. Overnight lows will drop into the upper 50s to mid 60s both nights. KEY MESSAGE 2... Beginning on Sunday, the dominant upper level ridge will begin to sink south across the Southern Plains which will allow a trough to dig over Great Lakes region. This upper level trough in conjunction with multiple mid-level shortwaves will provide synoptic energy to support periods of rainfall and thunderstorms through the middle of next week. Initially on Sunday, scattered showers and thunderstorms will be possible especially in the afternoon with the aide of daytime instability, but overall impacts should remain minimal. The greatest potential for severe weather will be on Monday as a moistening deep layer ahead of a cold front will push north across the area as a mid-level shortwave pushes east. Increased moisture coupled with daytime heating should result in adequate instability across the entire area. In addition, by Monday the area will be situated under the left exit region of the upper level jet, further enhancing lift and increasing deep layer sheer. These conditions should result in clusters of thunderstorms developing with some of them reaching strong to severe thresholds. There remains some uncertainty in the forecast this far out, especially with how any Sunday night precipitation may impact the forecast on Monday. If showers and clouds linger into Monday morning, there will likely be a diminished threat a bit given reduced instability. will have to closely monitor the evolution of model guidance over the next few days to get a better handle on storm potential Monday, but for now SPC has issued a Day 4 SWO with the entire area highlighted in 15%. && .AVIATION /00Z Saturday THROUGH Wednesday/... VFR conditions expected through the TAF period for a majority of terminals. There is potential for fog to develop from KMFD east through KYNG with the greatest confidence at KMFD and KCAK. Lingering cloud cover overnight may inhibit fog developing at KYNG, so opted to continue a TEMPO group for it. Any fog should dissipate by 12-13Z tomorrow morning. Winds will become light and variable overnight then predominately out of the west by mid-morning. A lake breeze is expected to impact KCLE and KERI tomorrow, shifting winds to be out of the north by 16-17Z. Outlook...Non-VFR possible with periodic showers and thunderstorms Sunday afternoon through Tuesday. && .MARINE... Overall marine weather conditions will be good on Lake Erie for this weekend. Northeasterly flow 10 to 15 knots will continue for this afternoon for the central and 10 knots less for the rest of the lake. Waves will be 1 to 2 feet in the central basin and a foot or less elsewhere through tonight. Winds will be light and variable 10 knots or less on Saturday with ideal boating conditions. Waves around a foot are expected Saturday into tomorrow night. Southwest flow returns Sunday through Monday around 10 knots. Southerly to southwesterly flow will increase 15 to 20 knots ahead of a cold front by Monday night and Tuesday morning. Behind the frontal passage Tuesday, winds will shift from the Northwest 10 to 20 knots and slightly higher waves. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None. MARINE...None. && $$ DISCUSSION...04 AVIATION...23 MARINE...77
