Wilmington, Ohio – Drivers in southwest Ohio should be prepared for reduced visibility from patchy fog before 9 a.m. Thursday, August 14. The National Weather Service (NWS) in Wilmington advises that fog may cause slowdowns on U.S. Route 68 and I-71 during the early morning hours. Once the fog clears, the region can expect mostly sunny skies and rising temperatures, with a high near 84°F.
While no storms are expected through at least Tuesday, the heat will steadily build through the coming days. By Friday, sunny conditions will continue with temperatures climbing to 87°F. The heat will intensify over the weekend, with highs reaching 88°F on Saturday and 89°F by Sunday. Although the skies will remain clear, prolonged exposure to direct sunlight could pose health risks. The NWS recommends staying hydrated, avoiding strenuous activity during peak afternoon heat, and checking on pets and vulnerable neighbors.
Saturday and Sunday nights will remain mild, with lows around 66–69°F, offering little overnight relief. The heat wave is expected to persist into Monday and Tuesday, with more sunshine and highs in the upper 80s. A slight chance of thunderstorms returns Tuesday afternoon, with a 30% chance of rain, although no major hazardous weather is currently expected.
