264 FXUS61 KCLE 061648 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 1248 PM EDT Sun Sep 6 2026 .WHAT HAS CHANGED... No significant changes to the previous forecast. && .KEY MESSAGES... 1) Seasonable and mainly dry weather will continue into Tuesday. 2) A brief period of above average temperatures will arrive on Wednesday with showers and thunderstorms possible. && .DISCUSSION... KEY MESSAGE 1... High pressure will persist across the Great Lakes region through Labor Day Weekend, ushering in seasonable and less humid weather. Highs will reach the upper 70s to lower 80s with lows generally in the 50s, though some isolated 40s are possible, especially across the interior areas Sunday night into Monday morning. A few lake-enhanced showers are possible later this morning and afternoon, though coverage remains uncertain given the latest satellite imagery revealing large pockets of dry air across the region associated with the high pressure subsidence. KEY MESSAGE 2... A strong upper-level trough will move east through the Upper Great Lakes on Wednesday, ushering in strong warm air advection across the Lower Great Lakes and Midwest. A brief period of heat and humidity will return across the region as heat indices reach the low to mid-90s in some spots Wednesday afternoon. The latest guidance indicates a narrow region of instability developing across the area in the midst of seasonably-strong mid and upper-level flow which could be favorable for some stronger storms in the afternoon and evening, though there remains uncertainty on coverage. Cooler and less humid weather will return across the region Thursday into Friday as a cold front moves east through the area and high pressure returns. && .AVIATION /12Z Sunday THROUGH Thursday/... Some low VFR clouds have developed across the region with incoming high pressure into the region and cooler air over warm Lake Erie. There may be some intermittent ceilings around 3-5 kft but clouds should remain few/sct through the evening. Clouds will clear with the diurnal cycle ending. Clouds will return on Monday morning with cold air advection over the lake. Winds will largely be northeasterly through the period. A land breeze may develop tonight and allow for southeast flow at KERI. Outlook...Non-VFR possible with showers and storms on Wednesday and lingering into Thursday. && .MARINE... Choppy marine conditions (waves 2 to 3 feet at times) will continue in the afternoon and evening hours over the next couple of days as onshore flow becomes diurnally enhanced, resulting in northeast flow up to 15 knots in some instances. Flow will shift towards the southwest ahead of the next system on Wednesday, with winds increasing into the 15 to 25 knot range. Small Craft Advisories may be needed during this timeframe. Winds will then shift towards the west to northwest behind a cold front on Thursday, 10 to 15 knots. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None. MARINE...None. && $$ DISCUSSION...Kahn AVIATION...Sefcovic MARINE...Kahn
