346 FXUS61 KCLE 172040 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 340 PM EST Mon Nov 17 2025 .SYNOPSIS... A weak low pressure system will move east through the Ohio Valley on Tuesday, followed by high pressure for Wednesday into Thursday. Another low pressure system will track east through the Ohio Valley as a cold front drops south across the Great Lakes on Friday. High pressure will gradually build in from the west by Saturday. && .NEAR TERM /THROUGH TUESDAY NIGHT/... Main concern for the near term period will be the potential for a brief period of wintry precipitation, including snow and sleet, Tuesday morning, particularly across Northwest and North Ohio. A weakening low pressure system will track east through the Ohio Valley late tonight into Tuesday as high pressure gradually exits east towards the Mid-Atlantic. A modest southwest LLJ will increase warm air advection into the area Tuesday morning, overrunning a generally cold near-surface air mass across the region with temperatures hovering around freezing. Wet snow will initially be the primary precipitation mode, though a brief period of sleet is possible as snow transitions to rain from southwest to northeast through Tuesday morning. Depending on precipitation intensity, can`t rule out some slick spots for the morning commute. Precipitation will transition to all rain by early Tuesday afternoon. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... Main concern for the short term period will be the potential for widespread rain showers Thursday night as an upper-level trough slides east across the Upper Great Lakes region. This will be a "warm" system with rain being the sole precipitation type as temperatures will in the low to mid-50s. Otherwise, weak high pressure will lead to mainly quiet and dry weather on Wednesday, though residual cloud cover may stick around for much of the day, limiting highs to the 40s. && .LONG TERM /FRIDAY THROUGH MONDAY/... Apart from uncertainty on precipitation chances for Friday, the long term period appears mainly quiet as high pressure is favored to build across the Tennessee and Ohio Valleys by the weekend and perhaps into early next week. For Friday, a cold front is expected to sag south through the Great Lakes behind the Thursday night system and stall across the Ohio Valley. Another area of low pressure is expected to track east along this front on Friday, though the latest guidance suggests the best chances for rain will be along and south of the US-30 corridor. Seasonable temperatures in the upper 40s to 50s are expected for the long term period. && .AVIATION /18Z Monday THROUGH Saturday/... VFR to start with a clear sky in NW OH, and on the overcast side eastward into NW PA with lingering lake effect cloud cover. Low pressure development to the west of the area has clouds increasing and lowering tonight into Tuesday as it moves eastward, with a shield of precipitation working its way into the region. Precipitation onset after 12Z for FDY/TOL, where TOL could start with a rain/snow mix for an hour or two before transitioning to all rain. ALl other terminals start as and continue as rain through the forecast period. Ceilings lower to MVFR an hour or two after onset, with IFR possible later in the TAF in prolonged precipitation in ceilings and visibilities. For the ERI terminal, BKN-OVC deck FL040 expected through around 06Z tonight, a brief break with high clouds, and then lowering once again. Winds W to WNW gusting to 25kts at times, easing through the later evening hours with brief high pressure moving through, light and variable tonight, and then E to NE Tuesday under 10kts. Outlook...Non-VFR to continue into Tuesday night. Possible return of non-VFR Thursday night into Friday with the next cold front and low pressure passing to our south. && .MARINE... Winds diminish this evening and tonight with high pressure moving into the southern Great Lakes. Wave heights down to less than a foot later tonight into Tuesday. As low pressure moves south of Lake Erie, winds become northeasterly for Tuesday night into Wednesday at 10-20kts, with western basin wave heights increasing to 1-3ft. High pressure returns for Wednesday night into Thursday with wave heights less than a foot, then becoming southwesterly 10-20kts Thursday night. A cold front comes through Friday, winds become northwesterly 10-20kts, and wave heights 2-4ft from Avon Point eastward. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None.
