224 FXUS61 KCLE 251842 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 242 PM EDT Thu Sep 25 2025 .SYNOPSIS... The upper level trough is currently over the Great Lakes region and will be slowly moving eastward through Friday. High pressure will build in for the weekend with a weak cold front moving through Sunday. Early next week, high pressure will build in north of the Great Lakes. && .NEAR TERM /THROUGH FRIDAY/... 930 AM Update... Adjusted PoPs for this morning into the afternoon to account for current radar trends. PoPs have been more widespread in eastern Ohio and should taper off into the afternoon. We are starting off this morning with patchy to areas of fog and mist. There are some patchy dense fog as well. As of this discussion, it doesn't seem widespread enough for an advisory at this time. We will continue to issue SPS for some fog through sunrise but keep an eye on trends if a headline is needed. An upper level trough will continue to move slowly eastward across the Ohio Valley and eastern Great Lakes region today. At the surface, an area of low pressure near southern Ohio will track northeastward across the Upper Ohio Valley today. The highest POPs for today will be along our southeastern CWA or mainly along a line from Mount Vernon to Ashtabula eastward. Average QPF will range between a tenth to half an inch of rainfall today. The upper level trough will begin to push eastward away from the region by tonight. With recent rainfall and wet ground, patchy to areas of fog may be possible once again tonight. Weak high pressure will build into the region on Friday. Skies will clear from west to east across the area on Friday. High temperatures today will be in the lower to middle 70s. High temperatures on Friday will be in the middle to upper 70s. Overnight low temperatures will be in the middle 50s. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/... High pressure will move into the region over the weekend and bring quiet weather. An upper level low will slowly move from the southeastern U.S. to the Mid-Atlantic region this weekend. This upper level low may throw back some high and mid level clouds over the area from time to time this weekend. Otherwise, it should be fair weather conditions this weekend. High temperatures will range from the middle 70s to lower 80s this weekend. Overnight low temperatures will be in the lower to middle 50s. && .LONG TERM /MONDAY THROUGH THURSDAY/... An upper level ridge will develop over the Midwest and Great Lakes region by early next week. High pressure at the surface will keep the weather quiet and slightly above average temperatures. High temperatures will range from the middle 70s to lower 80s early next week. Overnight low temperatures will be in the lower to middle 50s. A backdoor cold front may slide across the eastern Great Lakes by the middle of next week with slightly cooler weather. The weather forecast looks to remain dry for the early and middle of next week. && .AVIATION /18Z Thursday THROUGH Tuesday/... A couple showers remain across the eastern half of the airspace this afternoon as the main low pressure system and residual trough continue to depart the region. The fog and low stratus from this morning has taken several hours to lift and has largely done so outside of far eastern Ohio. The trend for this afternoon will be continue lifting and scattering of the lowest ceilings to some scattered VFR cumulus across the region. For tonight, clearing conditions with light winds will allow for a low level inversion to setup with ample near surface moisture. This will be ideal for more fog and low stratus to form and with the support of the slow decay of fog and stratus this morning and various operational guidance, was aggressive in IFR and LIFR for the TAFs. A drier air mass will enter on Friday with high pressure entering from the southwest and the Friday trend will be to clearing and VFR. Outlook...VFR is expected Friday afternoon through Tuesday. && .MARINE... A low pressure system and associated surface front will continue to depart the region and allow for northwest flow to persist on the lake. Another trough moving through the Great Lakes will allow for slightly elevated west to northwest flow to continue on Friday. For Saturday, the lake will be between the trough to north and a low pressure system moving up the East Coast and southwest flow will overtake the lake. After that, high pressure will enter from the west for the second half of the weekend into next week and light flow will be expected on the lake with some variable direction depending on lake/land breezes. No marine hazards are expected at this time. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None.
