802 FXUS61 KCLE 292318 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 718 PM EDT Fri Aug 29 2025 .SYNOPSIS... High pressure will continue to build across the Great Lakes region through the weekend before building east towards the Northeast early next week. Low pressure will drag a cold front east across the region towards the end of next week. && .NEAR TERM /THROUGH SATURDAY/... Cool and quiet weather expected as an upper-level low lingers over Quebec while high pressure builds over the Great Lakes at the surface. Chilly tonight with overnight lows dropping into the mid 40s areawide. Can`t rule out some overnight lows dipping near or below 40 degrees across sheltered valleys and typically cooler areas. A weak synoptic MSLP gradient accompanying the surface ridge and sufficient nocturnal cooling of surface air over land surrounding ~72F Lake Erie will permit land breeze development after midnight tonight and especially around daybreak Saturday. Localized river valley steam fog formation is expected and patchy radiation fog formation is possible after midnight tonight, especially along and east of I-71. Fog will dissipate by mid-morning, following the onset of diurnal convective mixing of the boundary layer. Dry weather continues Saturday with high temperatures in the upper 60s to lower 70s. Lows on Saturday night will settle in the mid to upper 40s. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/... Surface high pressure builds towards the Northeast through the short term with continued dry weather expected. Temperatures will rise a few degrees through the forecast period as the high builds east. Highs in the low to mid 70s Sunday will climb into the upper 70s by Monday. && .LONG TERM /TUESDAY THROUGH FRIDAY/... Surface high pressure continues to build east out of the Great Lakes region early next week. Rain chances return to the region mid-week as low pressure approaches from the west. The low will drag a cold front east across the local area on Thursday with another round of chilly temperatures expected behind the front. High temperatures in the upper 70s to near 80 degrees Tuesday afternoon will fall into the mid 60s by Thursday. && .AVIATION /18Z Friday THROUGH Wednesday/... NW`erly flow aloft persists as a low wobbles E`ward across southern QC to northern ME and a ridge builds from the northern Great Plains. At the surface, the ridge remains centered over the western Great Lakes and continues to build into northern OH and NW PA. A weak MSLP gradient accompanying the ridge will allow our regional surface winds to trend light and variable. However, a primarily SE`erly to S`erly land breeze around 5 knots should develop along and very near Lake Erie during the ~08Z/Sat to ~13Z/Sat time period, including at KERI. Fair weather and primarily VFR are expected through the TAF period. However, localized river valley steam fog should impact northern OH and NW PA between ~08Z/Sat and ~13Z/Sat. Patchy radiation fog is possible during the same time period, especially east of I-71, including at/near KCAK and KYNG. Visibility should vary between MVFR and LIFR due to variable fog density. Note: scattered to widespread lake-effect stratocumuli with bases near 5kft AGL are expected to stream generally SE`ward or S`ward from Lake Erie during the TAF period. These low clouds will impact KCLE/KCAK/KYNG/KERI and may impact KMFD at times. Outlook...Localized fog with non-VFR is possible around daybreak Sunday. Otherwise VFR are expected through this Tuesday. On Wednesday, isolated to scattered rain showers and thunderstorms with non-VFR should occur. && .MARINE... While a waterspout cannot be completely ruled out this evening as a weak surface trough drops across Lake Erie, the concern is fairly low overall given a relatively dry airmass and shallow convective cloud depths. Otherwise, marine conditions will be fairly tranquil for the foreseeable future with high pressure building in tonight and remaining the primary weather feature controlling our wind speed/direction through the first half of next week. Northerly winds through tonight will shift more east to northeast Saturday through Monday, then southeast Tuesday and Wednesday. Speeds will generally be <15kt the next several days. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None. MARINE...None. && $$ SYNOPSIS...13 NEAR TERM...13/Jaszka SHORT TERM...13 LONG TERM...13 AVIATION...Jaszka MARINE...Sullivan
