WILMINGTON, OH — A gray, calm morning hides what’s coming next: Ohio’s first measurable December snow. Clouds thicken across the Miami Valley and southern Ohio as a Winter Weather Advisory takes effect from 7 p.m. tonight to 10 a.m. Tuesday, with 2 to 4 inches of accumulation expected.
The National Weather Service in Wilmington warns of hazardous travel conditions developing this evening, especially along Interstates 70, 71, and 75, where falling snow and subfreezing pavement could quickly turn roads slick. Commuters should plan for delays and reduced visibility by late evening through the Tuesday morning drive.
Temperatures will hover in the mid-20s, allowing snow to stick easily. Winds from the east will shift northwest by dawn, ushering in drier air but keeping conditions cold and icy. Even after snowfall tapers Tuesday morning, patchy ice will remain a problem on bridges and side streets.
Tuesday brings calmer skies, though highs will barely reach the low 30s. The quiet won’t last — more snow chances return Friday into Saturday, part of a broader December pattern that’s signaling a colder, snowier start to winter across the Ohio Valley.
