The skies over Ohio are forecasting trouble as a relentless weather pattern grips the area. According to the National Weather Service, "waves of low pressure will result in more rounds of showers and storms," which translates to a weekend of heavy rain and a potential for flooding across Columbus, Cincinnati, Wilmington, and the surrounding locales. A Flood Watch is already in effect, extending through Sunday morning as the region braces for what's likely to be a very wet and potentially hazardous stretch.
Thursday kicked off with showers and storms, particularly across the southeast, though a mid-morning taper was expected. However, conditions are poised to grow more tumultuous with the approach of a "shortwave in the southwest flow aloft" triggering renewed thunderstorm development later this afternoon, the boundary itself settling south of the Ohio River and with highs hovering between the upper 60s and low 70s. Despite the boundary's southward slide and cooler climes lending to lower instability, those in the far south should remain wary—the threat of severe weather persist,s albeit low.
Into the evening and adjacent Friday, the showers and storms are anticipated to increase in frequency, ushered in by another low-level jet convergence, as the forecast discussion from the NWS states, "Deep moist flow from the southwest will interactive with embedded shortwaves and low-level jets to result in several rounds of rainfall which could be heavy, resulting in flooding." The overnight temperatures are likewise expected to drop, especially to the north, with a range from mid-40s to mid-50s.
Looking ahead, Friday night through Saturday won't provide any respite as high chances for showers and storms continue, and the NWS warns there's "the threat for some strong to severe storms." As a wave of low-pressure skates by and another cold front pushes southeast into the region, that period could bring the heaviest widespread rainfall against the already saturated landscape. Temperatures will see-saw from the mid-60s northwest to the lower 80s southeast on Saturday, but by Sunday, a sharp downturn should be expected - dipping to mid-40s northwest, touching near 60 in the far southeast. Beyond the weekend, an upper-level trough promises to bring unusually cool temperatures and a mix of showers, perhaps even some late snowfalls, early into the following week.
For anyone flying in or out of Ohio, expect travel disruptions. "Periods of showers and thunderstorms will occur into Sunday morning," the NWS cautions, leading to "MVFR/IFR conditions from time to time." The aviation outlook portends a complex mix of MVFR and IFR ceilings swirling in moderate to heavy rain. Monitor National Weather Service forecasts for the most up-to-date information, including the potential for severe weather alerts.
