954 FXUS61 KCLE 290546 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 146 AM EDT Wed Apr 29 2026 .WHAT HAS CHANGED... No major changes made to the forecast with this morning update. && .KEY MESSAGES... 1) Dreary Wednesday in store for the area as widespread rain showers move northeast across the area. No thunder expected, but localized heavy rainfall across southeastern counties possible. 2) Below average temperatures arrive today and stick around through the weekend. Low confidence lake enhanced rain showers possible and the potential for frost/freeze returns. && .DISCUSSION... KEY MESSAGE 1... Tonight, a cold front has pushed east of the area, stalling just west of the Appalachians. This boundary is providing a path for a low developing over the Tennessee Valley which is expected to track northeast towards New England today. Given the placement of this low, the entire CWA is expected to remain on the cold side of the low, ultimately limiting any instability potential today for thunderstorms to occur. Cannot rule out a few rumbles across the southeastern tier of counties, but confidence is too low to include in the forecast at this point. However, a potent shortwave pushing east will enhance synoptic support for widespread rain showers to occur across the CWA beginning this morning and lingering for much of today. The axis of highest rainfall totals will be across the southeastern tier of counties where up to 1" of rainfall is possible. Not expecting any flooding concerns at this point, but will monitor conditions as the day progresses. These showers should taper from west to east this evening into the early overnight hours as the aforementioned low and upper level support drift east. KEY MESSAGE 2... On Thursday and Friday, a surface trough will linger over the area, allowing for a much cooler Canadian airmass to begin to usher in across the area. This will ultimately lead to much cooler, below average temperatures through Friday with highs in the low to mid 50s and overnight lows dropping into the 30s. As this colder airmass pushes south over warming lakes, there is a potential for enough lake induced instability to develop to result in isolated light rain showers across the area. Confidence remains low at this point, especially in the location of any of these showers. Unfortunately, with this set-up, much of Thursday and Friday will be at least partly cloudy, lending to some cold and dreary days. On Saturday, a high pressure system will begin to build southeast across the area allowing for any shower potential to diminish and some clearing in sky coverage. Temperatures however will remain below normal on Saturday, slightly warming on Sunday into the upper 50s to low 60s. Sunday will mark the transition towards gradual warming once again towards normal. With the overnight lows expected to dip into the low to mid 30s, will have to continue to monitor for the potential of frost/freeze, especially on Thursday, Friday, and Saturday nights. && .AVIATION /06Z Wednesday THROUGH Sunday/... VFR on the font end of the TAF, but low pressure moving northeastward brings widespread showers/rain to the region after approximately 10Z this morning. Expect ceilings to lower to MVFR/IFR, depending on terminal, in precipitation that will last 4 to 8 hours for the most part. Winds to increase slightly this afternoon as low pressure strengthens as it nears the region, with gusts to 20kts possible this afternoon. Ceilings that were IFR should lift to MVFR late in the TAF period as precipitation exits to the northeast. Outlook...Non-VFR possible in showers Friday morning. && .MARINE... Winds and waves across Lake Erie have continued to subside this afternoon into the evening and drop below Small Craft criteria. Overnight, winds will become light at less than 10 knots across the lake and veer to be out of the north. By tomorrow evening, winds will increase slightly to 10-15 knots out of the north-northwest. Waves will build as a response to around 3 feet in the near shore with the on shore winds. Through the end of the week, quiet marine conditions are expected with winds varying between north to northwest at 5-10 knots and waves being less than 3 feet. Over the weekend, winds should back to be out of the west at 10-20 knots as high pressure moves to the south of the region. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None. MARINE...None. && $$ DISCUSSION...04 AVIATION...26 MARINE...23
