881 FXUS61 KCLE 200457 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 1157 PM EST Wed Nov 19 2025 .SYNOPSIS... A ridge affects our region through tonight as the embedded high pressure center moves from the central Great Lakes toward the northeast United States. As the ridge exits eastward, a warm front will drift northeastward across our region on Thursday before a cold front sweeps eastward through our region on Friday. Behind the cold front, a ridge builds from the western Great Lakes and vicinity Friday night before settling over our area on Saturday. && .NEAR TERM /THROUGH THURSDAY NIGHT/... Aloft, subtle ridging builds from the western Great Lakes and vicinity before cresting E`ward across our CWA on Thursday. During Thursday night, the ridge begins to exit E`ward as a shortwave trough approaches from the Upper Midwest and vicinity, and another shortwave trough moves NE`ward over/near the southern and central Great Plains. At the surface, the ridge continues to affect our region tonight as the embedded high pressure center moves from the central Great Lakes to the northeast United States. On Thursday through Thursday night, the ridge will exit E`ward. In addition, a warm front will drift NE`ward across our region on Thursday. Low temperatures tonight are expected to reach mainly the mid 20`s to mid 30`s around daybreak Thursday. Weak or calm surface winds, sufficient low-level humidity, and cloud breaks should permit patchy radiation fog formation late this evening through daybreak Thursday, especially roughly along and south of a Findlay, OH to Meadville, PA line. Any fog is expected to dissipate by late morning on Thursday, following the onset of diurnal convective mixing of the boundary layer. On Thursday, low-level WAA ahead of and behind the warm front and peeks of sunshine should allow late afternoon highs to reach the upper 40`s to lower 50`s. During Thursday night, strengthening low-level WAA behind the warm front should be accompanied by lows reaching the mid 30`s to lower 40`s around midnight, followed by slight moderation in air temperatures by daybreak Friday. Primarily dry weather is expected as stabilizing subsidence accompanies the ridge. In addition, a rather dry atmospheric column at/near 5kft to 8kft MSL should contribute to a dry warm front passage. However, isolated to scattered rain showers are possible Thursday night, especially after midnight, over/near Lake Erie and northern OH due to the following: moist isentropic ascent ahead of the Upper Midwest shortwave trough axis; low-level frontogenetical deformation aloft/associated moist ascent over/near the OH Valley given the expected evolution of the weather pattern at the surface and aloft. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... W`erly to NW`erly flow aloft is expected through Friday night as multiple embedded shortwave trough axes move generally E`ward or SE`ward over our region. However, during the predawn hours of Saturday morning, a ridge should begin to build from the northern and central Great Plains. At the surface, a cold front should sweep generally E`ward through our region on Friday. Behind the front, a ridge should build from the Upper Midwest and western Great Lakes through Friday night. Low-level WAA and a few peeks of sunshine should allow Friday`s highs to reach the lower to mid 50`s before the cold front passage. Behind the cold front, low-level CAA should contribute to lows reaching the the lower 30`s to lower 40`s around daybreak Saturday. Moist isentropic ascent aloft, ahead of the cold front, and low-level convergence/moist ascent along the front should allow scattered rain showers to impact northern OH and NW PA on Friday. Precip associated with the upper-reaches of the front should exit our region generally from west to east Friday night. Sufficient CAA at the surface and aloft may allow rain to mix with or change to wet snow before precip ends by daybreak Saturday. Any snow accumulations are expected to be a trace. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... The ridge aloft should continue to build from the northern and central Great Plains and vicinity through Sunday night. At the surface, the ridge should continue to impact our region as the embedded high pressure center moves from the western Great Lakes toward the central Appalachians. Dry weather is expected as stabilizing subsidence accompanies the ridge. Intervals of sunshine amidst continued low-level CAA should be accompanied by late afternoon highs in the 40`s on Saturday. Given the projected track of the surface high pressure center, low-level WAA should impact our region Saturday night through Sunday night and allow a rather moisture-starved warm front to sweep N`ward through our CWA Saturday night. Overnight lows should reach mainly the mid 20`s to mid 30`s during the predawn hours of Sunday morning. Intervals of sunshine should contribute to highs in the upper 40`s to mid 50`s late Sunday afternoon. During Sunday night, lows should reach the lower 30`s to lower 40`s around daybreak Monday. On Monday, the aforementioned ridge aloft should crest E`ward over our region as the surface portion of the ridge exits E`ward. In addition, subtle shortwave troughs should ripple generally E`ward through the ridge aloft. Daytime highs should reach the 50`s. During Monday night through Wednesday, cyclonic SW`erly to W`erly flow aloft and shortwave disturbances should impact the Lake Erie region, Upper OH Valley, and vicinity. At the surface, net surface troughing should impact our region and a cold front associated with a stronger shortwave trough should sweep E`ward in our CWA Tuesday night through Wednesday. Overnight lows should reach mainly the mid 30`s to lower 40`s around daybreak Tuesday and Wednesday, respectively. Daytime highs should reach the 50`s on Tuesday and the mid 40`s to lower 50`s on Wednesday. Periods of showers are expected Monday through Wednesday due to the following: moist isentropic ascent ahead of shortwave trough axes; low-level convergence/moist ascent along surface trough axes and the cold front. The showers will primarily be in the form of rain. However, sufficient nocturnal cooling may allow rain to mix with or change briefly to wet snow in spots around daybreak Monday and Tuesday, respectively, especially in interior areas east of I-77. At this time, little or no snow accumulation is expected. && .AVIATION /06Z Thursday THROUGH Monday/... MVFR ceilings due to stratus are impacting the western 2/3rds of the area as of 5z, including TOL, FDY, MFD and CAK. Farther east is currently observing VFR, though the clear skies and light winds do pose a fog concern early this morning there. Generally expect the stratus to persist/expand east, with ceilings likely coming down a bit more through the early morning hours. This, along with potential for fog development where clearing took place Wednesday evening, leads to a risk of IFR or lower ceilings along with some vsby restrictions for a few hours centered around 12z at MFD, CAK, and YNG. Confidence in these conditions has increased enough to include in the TAF at these locations, with a lower risk (20-30%) at FDY. Stratus will linger through Thursday. ERI may continue to see intermittent MVFR ceilings overnight, though generally is expected to prevail VFR through the TAF period. Light east winds will shift south on Thursday at less than 7 knots. Outlook...Non-VFR conditions may return with rain Friday and Saturday. && .MARINE... Quiet weather conditions are expected on Lake Erie as high pressure moves eastward across the Great Lakes tonight towards the east coast by Thursday night. Southwest flow around 10-15 knots develops Thursday night into Friday before turning northwest and north behind a cold frontal passage on Friday. High pressure returns over the weekend will relatively quiet weather ensuing, though perhaps there may be a brief period of choppiness in the central basin Friday night with north flow of around 10-15 knots. && .CLE WATCHES/WARNINGS/ADVISORIES...
