CINCINNATI, Ohio – Damp streets glisten under early Tuesday clouds as another wave of steady rain builds across southwest Ohio. Winds carry a cool edge through the Ohio River valley, setting up a gray, unsettled stretch before a drier — though chillier — Halloween weekend.
According to the National Weather Service in Wilmington, scattered showers will become steadier through Tuesday afternoon and persist into Wednesday. East winds between 10 and 20 mph will keep temperatures in the 50s, with patchy fog possible along the I-275 loop and low-lying areas near the Little Miami River. Drivers should expect slower commutes and occasional ponding in poor drainage spots.
Rain continues Wednesday with the heaviest activity expected from midday through evening, especially across Hamilton, Clermont, and Boone Counties. New rainfall amounts could reach a half inch in spots before tapering Thursday. As winds shift north, cooler and drier air will move in — a pattern change that will drop highs back into the low 50s by Thursday afternoon.
By Friday, skies clear and the chill settles in. Halloween night temperatures hover near 40°F, with a light breeze off the river making it feel a few degrees cooler. Trick-or-treaters should bundle up in layers under costumes, though the dry air will help keep streets clear and safe for festivities.
Looking ahead, the first weekend of November stays partly sunny but cool, with highs in the 50s and lows dipping near freezing in rural areas south of I-74. After all, a chilly November is lining up across the Ohio Valley.
