The National Weather Service in Cleveland has issued a detailed forecast discussion for the coming days, as a stubborn cold front and weak low-pressure system will finally release its grip on the Ohio Valley. Following a soggy Thursday, the weather is expected to dry out, with Friday bringing much cooler temperatures, a welcome change after a wet and warmer spell.
According to the NWS forecast, "The area is in the midst of a pattern change that will result in a wet Thursday, followed by a drying and well below normal Friday." As the front clears out by late afternoon, temperatures are set to hover around the 70-degree mark today. The forecast includes a 100% chance of precipitation across a significant portion of the area, with some potential for thunder embedded in the rainfall through early afternoon. After a week and a half of warmer nights, lows are expected to dip below 60 degrees for the first time.
As we move into Friday, high pressure is forecasted to build from the north, paving the way for generally dry conditions. The NWS outlook for the weekend maintains this dry trend with high temperatures in the mid-70s to lower 80s, offering a cooler respite. "High pressure will remain across the region for the short term forecast period on the back side of an upper trough anchored over the eastern CONUS," the NWS articulated in their discussion.
Looking ahead to next week's weather patterns, some rain chances may reemerge as high pressure shifts east and moist, humid air begins to infiltrate the region. "By Tuesday, an upper trough will swing through the Great Lakes region and could be a source for shower and storm development for the middle of the week," the NWS added, noting that the threat of severe weather is currently deemed low given the mild upper jet strength and unremarkable placement. As it stands, expect the possible return of widespread 80s after the exit of the cold air.
The marine forecast is particularly cautionary, with rough conditions expected across Lake Erie, especially from the Islands eastward. "Recreational boating and swimming is strongly discouraged on Lake Erie today and tonight," the NWS warns, highlighting that brisk northeast winds will make for dangerous conditions. Those Small Craft Advisories and Rip Current Statements aren't lifting anytime soon, but by Friday evening, some improvement can be expected.
