967 FXUS61 KCLE 081835 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 135 PM EST Mon Dec 8 2025 .SYNOPSIS... High pressure will move through the region today. A series of low pressure systems will move through the region for the middle of the week with a weaker low on Tuesday, followed by a stronger low on Wednesday. High pressure will briefly return for Thursday before more unsettled weather for the weekend. && .NEAR TERM /THROUGH TONIGHT/... Cold northerly flow ahead of high pressure has allowed for some clouds and light snow showers to develop with some lake effect off Lakes Huron and Erie. The amount of moisture in the region with the surface high approaching is very limited so any impacts are just some clouds and a couple flakes in the air but do not expect any accumulations this morning. For the daytime hours today into tonight, expecting dry weather across the region with high pressure in place. Temperatures will continue to be below normal with this surface high bringing more cold air to the region over a light snow pack. Temperatures tonight will be in the teens to upper single digits. With just some light winds, wind chills could be near to just below zero in spots. && .SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/... The middle of this week continues to appear active with a sequence of troughs and a pair of low pressure systems expected to move through the Great Lakes. For Tuesday, an initial shortwave will dig into the region and support a weaker low pressure system through the northern Great Lakes. The forecast area will be on the periphery of this system with a warm front passing through the area on Tuesday afternoon and evening. There will be some snow for NE Ohio and NW PA with the warm front with an inch or so possible in NW PA by Tuesday evening. For Tuesday night, the area will be in a warm advection pattern, as the next, stronger upper trough and low pressure enter for Wednesday. Precipitation will enter Tuesday night with this system and with some warmer temperatures in the 30s to lower 40s, expect a transition to rain for most of the forecast area with the onset of this system. Some snow may stick around NW PA, where another inch of snow could accumulate. On Wednesday afternoon, this system will pass to the east and extend a cold front across the area, allowing for rain to change to snow for all locations and some minor accumulations will be expected across the board. Some lake enhancement will allow for another inch or two of snow in NE OH/NW PA by Wednesday night. Another concern for the Tuesday night through Wednesday night period will be winds as a strong low level jet will move through the region with the low pressure system and cold front. Wind gusts as strong as 40-45 mph are possible on land and there is potential for a wind advisory, depending on the low pressure system track. For Thursday, there still is uncertainty on how much snow will be in the region behind these systems. The end track of the Wednesday system will determine how long a trough will remain over Lake Erie to allow for some lake enhanced snow into the eastern half of the area before high pressure and a low level ridge build into the region and allow for snow chances off Lake Erie to end. Will maintain a generic mix of PoPs across the area until these features can be resolved. Overall, not expecting too much snow for Thursday. && .LONG TERM /FRIDAY THROUGH SUNDAY/... The long term forecast will continue the cold and unsettled pattern that has been featured so far in December. There are some model disagreements on timing and strength of systems. However, in general, a low pressure system will move through the Great Lakes region on Friday, ushering another reinforcing shot of cold air across the local area while allowing for some widespread light snow. Behind this system, some component of a surface trough will set up over the region and allow for lake effect snow for Saturday and Sunday with the best chance for accumulations in the traditional areas of NE Ohio and NW PA. If some of the colder model solutions like the 00z GFS can be realized, there would be some potential for some significant lake effect snows in the Great Lakes region. However, there is too much spread in the guidance at this time to say anything more than that the lake effect machine will be going this weekend. && .AVIATION /18Z Monday THROUGH Saturday/... Generally expect VFR conditions through the TAF period, however low pressure will move east across the northern fringe of the local area on Tuesday, resulting in lower ceilings and possibly some light snow showers at KTOL and KCLE late in the TAF period. Ceilings will likely fall to low-end VFR from KCLE to KMFD and locations west with patches of MVFR ceilings/visibilities possible in light snow. Winds will be out of the east/northeast at 6 to 12 knots before becoming light and variable tonight. South/southwest winds will develop late tonight and increase to 10 to 16 knots with gusts to 25 knots by late morning/early Tuesday afternoon. Outlook...Non-VFR is expected with snow on Tuesday afternoon and Tuesday night which will gradually transition to rain by Wednesday morning. Rain will transition back over to periods of snow Wednesday evening through Saturday. Gusty winds are likely Tuesday and Wednesday. && .MARINE... Marine weather conditions on Lake Erie will be very unsettled and rough throughout this week, especially Tuesday through Wednesday night. High pressure is currently building over the Great Lakes region this morning. Winds are starting out from the Northeast 15 to 20 knots this morning with waves of 3 to 5 feet. There is a Small Craft Advisory through mid morning for the central and eastern nearshore marine zones. Winds and waves will relax later today becoming easterly 10 to 15 knots and 1 to 3 feet. Winds will become southerly tonight 10 to 15 knots and waves 1 to 3 feet. A low pressure system will track across the Upper Great Lakes region on Tuesday with an increasing southerly flow 15 to 30 knots and waves building 5 to 8 feet in the nearshore zones, higher in the open waters. Additional Small Craft Advisories will be likely on Tuesday. There is some potential of winds approaching Gales on Tuesday in the open water. Marine conditions will further deteriorate Tuesday night into Wednesday ahead of stronger low pressure system tracking through the Great Lakes region. Southwest Gales 35 to 40 knot increasing likely Tuesday night through Wednesday for most of the central and eastern basin of Lake Erie. Waves will further increase 8 to 14, if not higher in the open water Tuesday night into Wednesday. A strong cold front will switch the winds from the northwest 15 to 25 knots Wednesday night into Thursday and waves 4 to 8 feet. Additional SCA will likely be needed Wednesday night through Thursday. Another strong cold front will move across the lake Friday into Saturday with gusty northwest winds 15 to 30 knots and higher waves. Additional marine headlines will be likely late this week into the weekend. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None.
