357 FXUS61 KCLE 151805 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 205 PM EDT Wed Oct 15 2025 .SYNOPSIS... High pressure will build across the region today and persist into Friday. A warm front will lift north across the area Friday night into Saturday ahead of a low pressure system. This system will extend a cold front east through the area on Sunday. && .NEAR TERM /THROUGH THURSDAY/... Outside of the potential for frost late tonight into Thursday morning, generally quiet weather is expected for the near term period as high pressure builds across the region. For this morning, beginning to see radar returns across portions of central and southern Michigan with the highest precipitation chances likely focused along the northern half of our area through sunrise. However, it may be difficult for much rain to reach the surface given upstream cloud decks remaining elevated around 9 to 10kft, in addition to mainly trace amounts of rainfall being reported at surface observation sites. Otherwise, high pressure will gradually build south and expand across the Great Lakes through Thursday, leading to seasonable temperatures in the low to mid-60s. Clear skies and light winds late tonight will result in low temperatures falling into the low to mid-30s across portions of Northeast Ohio and Northwest Pennsylvania where a Frost Advisory remains in effect. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... Active weather will become more likely for the short term period, particularly near the end of the period Saturday night. A more widespread threat for frost and potentially freeze conditions is likely Thursday night into Friday morning. High pressure will remain in control for Thursday night into Friday with clear skies and light winds resulting in low temperatures falling into the low to mid-30s, and perhaps even the upper 20s in some spots across Northwest Pennsylvania. Anticipate the frost/freeze potential will be more widespread compared to the previous night, with headlines likely needed west towards the I-71 corridor. Otherwise, a warm front will lift northeast through the area Friday night into Saturday which may result in scattered rain showers, particularly across the northern half of the area. Much of Saturday should stay dry ahead of the approaching system as increasing warm air advection results in well-above average temperatures in the upper 70s to near 80. By late Saturday night, widespread rain and perhaps a few isolated thunderstorms will begin to arrive from the west, aided by a modest south to southwest LLJ of around 35 knots as as a large upper- level trough moves east through the Upper Great Lakes. The recent suite of model guidance is perhaps a touch slower which could delay the heavier precipitation until late Sunday morning or early afternoon. && .LONG TERM /SUNDAY THROUGH TUESDAY/... Active weather will continue for at least the first half of the long term period as a cold front sweeps east through the area on Sunday. Additional moderate to heavy rainfall and perhaps a few isolated thunderstorms are most likely Sunday afternoon and evening, particularly along and east of the I-71 corridor. Will need to watch for a developing TROWAL Sunday night into Monday on the backside of a deepening low pressure in the vicinity of the Eastern Great Lakes, though uncertainty does begin to increase given the volatility of the upper-level pattern. High pressure will begin to build across the Tennessee Valley on Monday and may expand into at least the Lower Ohio Valley, though confidence is low on its northern extent. Another upper- level trough is expected to race east across the Upper Midwest and Great Lakes by Tuesday, though confidence remains low on any potential impacts across the area. Mainly seasonable weather is expected to continue for the long term period with highs in the low to mid-60s. && .AVIATION /18Z Wednesday THROUGH Monday/... Mainly VFR conditions will continue through the TAF period. A mid-level cloud deck is bringing 5-10,000 foot ceilings from CLE-CAK points west this afternoon, but will exit to the south- southwest this evening. There are scattered cumulus in the 2,000 to 3,000 foot range, with CLE and CAK potentially seeing transient broken MVFR ceilings from those clouds before 20z. Mainly clear conditions are then expected tonight into Thursday. Winds will remain out of the north-northwest at 8 to 12kt this afternoon, slackening slightly to <7kt overnight tonight. Winds kick back up to 6-12kt out of the north on Thursday. Outlook...Generally VFR is expected through Friday. Scattered showers with a warm front may bring limited non-VFR Friday night. Strong low pressure will track into the Great Lakes on Sunday, pushing a cold front across the local area. Non-VFR due to showers/thunderstorms and gusty winds are possible with this system, especially Sunday and Sunday night. && .MARINE... Mainly quiet marine conditions are expected over Lake Erie through Friday as high pressure currently over the Upper Great Lakes builds in on Thursday and remains in control through Friday evening. A push of 14-18kt north-northeast winds is expected this evening through early Thursday morning, building 2-4 foot waves in the central and eastern basins (1-3 foot west). Conditions will near Small Craft Advisory criteria in the central basin tonight. Will closely evaluate the updated wave forecast before sending the final marine products later this afternoon and evaluate if a brief advisory is needed, though potential for 4 foot or larger waves appears fairly brief and marginal, which likely will preclude the headline. Winds will diminish to under 15kt Thursday morning and remain under 15kt through Friday while shifting east and then south. A warm front will lift across the lake Friday night, allowing winds to increase out of the south-southeast to 10-20kt through Saturday. Winds increase further Saturday night into Sunday at 15-25kt ahead of an approaching cold front. This strong cold front crosses Sunday afternoon or evening as deepening low pressure tracks through the Great Lakes, shifting the winds out of the west or northwest. Model guidance varies wildly on how quickly the aforementioned low pressure deepens Sunday into Sunday night, with some disagreement on the track of the low too. Recent guidance has trended towards a stronger low tracking to our north and northeast, which would be a favorable trend for stronger winds over the lake, potentially reaching gales behind the front and departing low late Sunday or Sunday night. The current forecast has 20-30kt westerly winds behind the cold front through Sunday night before slackening slightly to 15-25kt Monday-Tuesday. Probabilities for peak sustained winds exceeding gale-force Sunday or Sunday night, per the most recent NBM v5.0, ranges from 10-30% in the western basin to 20-40% in the eastern basin and 40-60% in the central basin. Small Craft Advisories will be needed for all nearshore zones starting Saturday or Saturday night into early next week. Gale headlines may be needed for at least a portion of that window Sunday into Sunday night. If the wind direction remains primarily westerly, winds appear as if they`ll be strong enough to create low water issues in the western basin late Sunday into early Monday. && .CLE WATCHES/WARNINGS/ADVISORIES...
