574 FXUS61 KCLE 230526 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 1226 AM EST Sun Feb 23 2025 .SYNOPSIS... A ridge continues to build from the Tennessee Valley and central Appalachians through Sunday. Beginning Sunday night, the ridge exits slowly eastward before a cold front sweeps eastward across northern Ohio and northwest Pennsylvania on Tuesday. Behind the front, a narrow ridge builds eastward through Tuesday night. On Wednesday, this ridge should exit eastward as another cold front approaches from the Upper Midwest. && .NEAR TERM /THROUGH TODAY/... 9:30 PM Update... A mid/upper shortwave is entering eastern Lake Erie and will drop into the Mid Atlantic by morning. Very dry low-level air remains in place, so no precip is expected other than virga aloft, so kept the forecast dry overnight. Temps, dew points, and winds look good. 6:30 PM Update... The forecast continues to look reasonable this evening. The boundary layer has started to decouple with sunset, so winds will rapidly subside over the next hour, and expect generally SW winds of 5-10 knots the rest of the evening. Original Discussion... Aloft, W`erly to WNW`erly flow and embedded shortwave disturbances affect our region through Sunday night. Moist isentropic ascent preceding the shortwave trough axes will allow periodic mid/upper- level cloudiness to impact our region. At the surface, our CWA remains along the northern flank of a high pressure ridge. The core of this ridge is expected to remain in vicinity of the TN Valley and central Appalachians. Stabilizing subsidence and a rather dry low- level atmospheric column accompanying the surface ridge are expected to allow fair weather to persist in northern OH and NW PA. S`erly to SW`erly regional surface winds along the northern flank of the ridge will be associated with net low-level WAA and a gradual moderating trend in temperatures. Overnight lows are expected to reach the upper teens to lower 20`s around daybreak Sunday. During late Sunday afternoon, highs are expected to reach the 30`s as the aforementioned low-level WAA is complemented by peeks of sunshine and resulting daytime warming. Sunday night is expected to be milder. Lows should reach the mid to upper 20`s across northern OH and NW PA around daybreak Monday. && .SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/... Above-average temperatures are expected for the short term period with highs generally in the mid-40s for both Monday and Tuesday. A strong low pressure system will move east across Hudson Bay on Monday, with a tight pressure gradient resulting in elevated south to southwest wind gusts of 25 to 30 mph in the afternoon. A secondary upper-level trough axis will arrive Monday night into Tuesday which could result in a brief period of scattered to perhaps widespread rain showers, though amounts appear to be generally light - a tenth of an inch or less. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Above-average temperatures are favored to continue for the long term period with daily highs generally in the mid-40s. The warmest day appears to be Wednesday ahead of a series of systems to end the week, with highs approaching the lower 50s. The first system will arrive Wednesday evening and overnight, associated with an upper-level trough. Primarily rain is expected with this system, with amounts slightly higher than the Monday system earlier in the week, albeit still light overall - a quarter of an inch or less. Anticipate much of the current snowpack to have melted by the time this system arrives, but may still need to monitor area rivers for a low-end flood potential. Lingering upper- troughing may result in light precipitation Thursday and Thursday night, though confidence remains low on coverage. Finally, another upper-level trough will sweep east through the Upper Midwest and Great Lakes on Saturday, ushering in another round of unsettled weather. Precipitation type appears to be primarily rain, though can`t rule out some mixed snow. Once again, precipitation amounts appear to be on the lower end of the spectra with this system. && .AVIATION /06Z Sunday THROUGH Thursday/... Widespread VFR conditions will continue to persist through this period. Currently, scattered cloud decks of 10kft are being observed across the western terminals and the eastern terminals with much of the central areas reporting SKC. By this afternoon, a widespread cloud deck will build over the area, but maintain VFR heights and visibilities. Winds are expected to persist from the southwest at 5-10 knots for all terminals today before gaining a bit more southerly component this evening and weakening to around 5 knots. Outlook...Periodic rain showers with non-VFR possible Tuesday through Thursday. && .MARINE... Lake Erie is primarily ice-covered and thus Small Craft Advisory issuance remains suspended until further notice. No additional marine headlines are expected through the upcoming week. South to southwest winds may peak in the 20 to 25 knot range on Monday, and will need to monitor any significant breaks or shifts in the ice across Lake Erie. Otherwise, winds are expected to generally range in the 10 to 15 knot range for the rest of the period. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None.
