963 FXUS61 KCLE 301131 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 631 AM EST Tue Dec 30 2025 .SYNOPSIS... A surface trough will linger across the Great Lakes region today into Wednesday before an area of low pressure moves through the eastern Great Lakes on Wednesday. The low will drag a cold front southeast across the region Wednesday night into Thursday. High pressure begins to build into the region on Friday and persist into the weekend. && .NEAR TERM /THROUGH WEDNESDAY/... TLDR: Biggest change to the forecast on this shift was to make some adjustments to the winter weather headlines, both in severity and in time. The Winter Weather Advisories for Summit, Portage, and Trumbull Counties remain unchanged and will expire at 1 PM today as lake effect showers ease. Elsewhere, expanded the Lake Effect Snow Warning to include Ashtabula, Lake, and Northern Erie (PA) Counties where confidence in warning amounts of snow are the highest. Maintained the Winter Weather Advisory for Cuyahoga County given lower confidence in 6+ inches of snowfall with the next round of lake effect snow. The Advisory for Cuyahoga County and the Lake Effect Snow Warning for the Ohio Counties (Geauga, Lake, Ashtabula) are now in effect through 7 AM Thursday. The Lake Effect Snow Warning for Northwest Pennsylvania is in effect through 7 PM Thursday. Persistent areawide lake effect snow showers are expected to last through late this morning/early this afternoon before becoming focused over the primary Snowbelt as winds back westerly. Additional snowfall accumulations with the lingering lake effect snow through this afternoon will generally range between 1 and 3 inches across Northeast Ohio and 3 to 5 inches across Northwest Pennsylvania. Blowing and drifting snow will continue to be a concern through this afternoon as snow ratios remain in the 18:1 to 20:1 range and northwesterly winds continue to gust to 25-30 MPH. Anticipate for winds to ease through the day today as they turn westerly to southwesterly. There will be a very brief window this evening where the ongoing lake effect snow showers diminish ahead of another impactful period of lake effect snow sets up across the region tonight and lasts through Thursday. The initial redevelopment of lake effect snow will remain hugged against the Lake Erie lakeshore tonight under westerly mean layer flow. Simultaneously, a weak clipper system will push east across the region overnight tonight bringing 1-2" of snowfall across much of the region. However, higher snowfall amounts of 3-6" will be possible along the lakeshore where the initial lake effect band sets up. Lake effect snowfall continues on Wednesday but will quickly ramp up in coverage and intensity Wednesday afternoon/evening as a strong upper trough and surface cold front push south across the local area. Expect widespread snowfall and continued lake effect snowfall to impact the region Wednesday evening. Increasing winds ahead of and with the crossing trough axis will increase the potential for snow squalls Wednesday evening, particularly across Northeast Ohio and Northwest Pennsylvania. The timing is less than ideal given the holiday evening and hazardous travel conditions possible NYE night. Plan accordingly. Highs in the mid 20s this afternoon will rise a few degrees to the upper 20s on Wednesday. Lows tonight fall into the upper teens with wind chills in the single digits. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/... Lake effect snowfall will continue overnight Wednesday into Thursday morning before gradually tapering off through the Thursday evening as low levels dry out. Another upper level shortwave may clip extreme northeast portions of the forecast area on Thursday night into Friday which may reinvigorate lake effect snow showers. However, there remains a bit of uncertainty given the approaching ridge of high pressure and dry air across the region. Much cooler Wednesday night behind the crossing cold front with lows dropping into the single digits to low tens and wind chill values near zero Thursday morning. Highs on Thursday settle in the lower 20s with lows in the teens and single digit wind chills likely Thursday night. Slightly warmer by Friday with highs in the upper 20s though overnight lows in the teens are expected. && .LONG TERM /SATURDAY THROUGH MONDAY/... Quieter weather expected this weekend under high pressure. Models continue to hint at a weak low pressure system moving east across the Great Lakes region Sunday night into Monday. This low could lead to another window of lake effect snow across the Snowbelt to begin the first full week of 2026. Highs in the upper 20s to low 30s and overnight lows in the upper teens to lower 20s through the long term. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... Lake effect snow showers will continue through much of the TAF period for the majority of the sites. A few sites may have breaks in the snow throughout the day as a brief lull occurs and conditions may improve to VFR. Ceilings currently are MVFR across the region and are expected to continue through the TAF period. The main driver for category changes will the visibility within the snow bands throughout the day. Another round of widespread snow showers are expected this evening as a low pressure system enters from the northwest. Visibilities will likely drop down to IFR across all sites, but can't rule out dropping to LIFR at times during heavier snow bands. Am not expecting any sites to recover out of MVFR visibilites during this TAF period. Westerly winds have begun to settle around the region with sustained winds of 10-15 knots and gusts around 20 knots. The exception being sites along the lake shore to including KERI which will stay gusting up towards 30 knots through 00Z tonight. Outlook...Non-VFR conditions are expected across the region due to lake effect clouds and snow through Thursday. && .MARINE... Gale Warnings continue across Lake Erie today, though conditions will be improving with winds and waves diminishing from west to east. The warnings will should be allow to expire in the open waters and downgraded in the nearshore at their respective times but can be adjusted as needed should conditions improve quick enough. That being said, after this evening winds will generally be out of the west to southwest at 15-25 knots through Friday. There will be points of elevated winds in the central and eastern basins as a cold front and trough traverse the lake Wednesday evening through Thursday morning though should stay below gales. Waves will stay elevated as well being between 8-15 feet in the central and eastern basins and 4-7 feet west of the islands through this evening. Waves won't begin to subside east of the islands until Friday evening when the winds begin to weaken across the lake. Quieter marine conditions are expected to start the weekend as high pressure builds into the region from the west. && .CLE WATCHES/WARNINGS/ADVISORIES...
