Columbus is starting Sunday with clear skies, temperatures in the mid-30s and a freeze warning that will keep an early-morning chill in place. The payoff arrives later: sunshine, light winds and a high near 63 degrees.

Freeze Warning Runs Through 9 A.M.

The National Weather Service in Wilmington says the freeze warning remains in effect through 9 a.m. Sunday, with temperatures potentially falling as low as 30 degrees across central Ohio. The weather service warns that frost and freezing conditions could damage sensitive plants and unprotected outdoor plumbing.

Frost could linger into the morning before fading as the sun climbs. Winds will stay light from the southeast, and there is no rain in the forecast for Sunday.

Sunny Stretch Builds Through Thursday

Monday will bring another chilly start, with areas of frost possible between 7 and 9 a.m., followed by a sunny high near 67 degrees. Tuesday and Wednesday should reach about 69 degrees, while Thursday tops out near 70 under mostly sunny skies.

The warm afternoons will come with crisp nights, including lows near 38 degrees Sunday night and around 39 degrees Monday night. Overnight temperatures gradually moderate into the 40s later in the week, but the forecast stays dry through Saturday.

For Columbus residents, the practical move is simple: protect tender plants before heading into Sunday morning and expect a sharp difference between the cold start and the comfortable afternoon. After that, the forecast settles into a remarkably sunny run, with mild fall afternoons replacing the freeze-warning wake-up call.
