As the Ohio Valley braces for wetter weather, the National Weather Service in Wilmington has issued a forecast predicting that light rain will continue mainly south of the Ohio River, gradually tapering off this morning and leading to drier conditions across much of the Columbus and Cincinnati areas today. The rain is set to return in full force on Wednesday and persist through Thursday, accompanied by a dip in temperatures that will persist until the week's end, according to a statement from the National Weather Service.
For those caught beneath the blanket of clouds, expect highs ranging from the mid to upper 50s; however, those basking in more sunshine might see the mercury hit around 60 degrees. The weather shift comes courtesy of an upper-level low pressure system strengthening over the Plains, then migrating into the Lower Mississippi Valley on Wednesday, according to the forecast discussion published early Tuesday morning by the National Weather Service in Wilmington, Ohio and despite the widespread anticipation of rain and cooler air, dry patches are expected to linger through tonight, especially more toward northern communities.
By Wednesday evening and through the bulk of Thursday, steady rain is anticipated to enfold the region with the most consistent and potentially heaviest downpours projected near and south of the Ohio River, and along the east side of the Interstate 71 corridor. The NWS Forecast Discussion notes, "Frontogenetical forcing amidst a saturated profile will promote the maintenance of a cohesive band of steady rain," which may introduce at least 1 inch of rainfall in those areas, while drier zones to the northwest could see significantly less.
Tail-end forecasts indicate a reprieve following the persistent rainfall, with Thursday night through Friday expected to showcase mixed sun and clouds and slightly more agreeable temperatures, albeit below the seasonal norm. Looking onward, another system is slated to skirt through over the weekend, posing for additional cloud cover and potentially light rain showers, prolonging this period of below-average temperatures remarked in the forecast discussion from the National Weather Service, as a constant reminder of autumn's cool embrace—unwavering and increasingly felt across the eastern United States.
