CINCINNATI, OH – A quiet, golden sunrise spreads across the Ohio River Valley this Monday morning, wrapping the region in calm before the chill. After a warm and steady start to the week, the National Weather Service in Wilmington warns that a first frost could arrive late Thursday into early Friday — a sign that autumn’s easy days are numbered.
Today stays mostly sunny and mild, with highs near 65 °F across Cincinnati and northern Kentucky. Winds remain light, but subtle shifts in air mass begin tonight as temperatures dip into the upper 40s and clouds drift in from the west. A weak disturbance could trigger a brief sprinkle before dawn Tuesday, though most areas stay dry.
By Tuesday afternoon, sunshine returns and highs climb near 67 °F. West winds will freshen, gusting up to 25 mph and ushering in noticeably drier air. From there, a cooling trend begins to tighten its hold — highs drop back into the upper 50s to low 60s by midweek, and lows tumble into the 30s late Wednesday night.
The biggest change arrives Thursday night into Friday morning, when clear skies and calm winds could allow frost to form across rural and low-lying areas. Gardeners should cover sensitive plants, and drivers should expect frosted windshields during early commutes.
The weekend looks brighter, with sunshine and highs near 60 °F. Still, this pattern signals the Ohio Valley’s first flirtation with winter — a gentle warning before stronger cold snaps arrive as Halloween week approaches.
