As Columbus, Cincinnati, and Wilmington brace for another scorching day, folks might want to keep their fans on and water bottles handy. The National Weather Service has forecasted unseasonably warm and humid conditions to persist through Friday, August 30th, before a cold front ushers in cooler, drier air come Sunday. National Weather Service also predicts isolated to scattered storms today, with more widespread showers and storms expected Saturday.
According to NWS, today's heat could be undercut by various factors, including storm development, which is expected to be more widespread than Thursday's. With storms in the early stages, focused across parts of Northern Kentucky and the Tri-State areas into south-central Ohio by mid-afternoon, and moving northeast into central Ohio near or east of I-71 by late afternoon, this could hinder the heat index from reaching predicted highs. Despite temperatures soaring into the mid to upper 90s, "heat index values will be approximately the same as the temps themselves, with dewpoints in the lower to mid-60s," National Weather Service forecasts. Rather than issuing a warning, they've released a Special Weather Statement advising locals to anticipate heat indices in the mid to upper 90s by late afternoon.
As folks seek respite in the cool of their homes tonight, the weather service alerts that the intermittent showers and thunderstorms are expected to continue, poised to increase in strength on Saturday morning from the north/northwest. While severe storms seem unlikely due to a lack of favorable atmospheric conditions, the NWS cautions that there is still "a nonzero" chance of isolated damaging wind occurrences. Any wrath from the skies should be tempered by recent dry spells and a presumed progressive storm movement, keeping flooding concerns on the down low. However, certain locales might still receive one to two inches of rain, particularly near or south of the Ohio River.
Looking past the weekend, the National Weather Service provides a glimmer of respite as the troubling front is expected to take its leave Saturday night, making room for a dry Sunday with a modest northwest flow. The ensuing cooler and drier air mass, trailing behind with some reluctance at the ground level, will dip temperatures to more agreeable mid-to-upper 70s to start the week. As the parched earth yearns for moisture, the continued forecast of dry conditions hints no reprieve for areas caught in drought's tight grip however, as the new week wades in, a gradual warm-up is expected to wistfully blow in, setting daytime highs back into the middle 80s by mid-week.
Pilots navigating the Ohio skies might face some visibility and wind irregularities associated with the afternoon's forecasted showers and thunderstorms. The aviation sector will operate against a backdrop of predominant VFR conditions, with moments of concern where amendments to flight operations may be warranted, especially between 18Z and 23Z for airports like CVG, LUK, CMH, and LCK. As these transient celestial dramas unfold, watch for on-the-fly adjustments as necessary, keeping an eye on the sky, as NWS advises.
