Columbus is starting Sunday clear and cool near 48 degrees, but the day will quickly turn sunny and mild. Temperatures are expected to reach about 75 degrees by afternoon, giving outdoor plans a comfortable late-September backdrop before a wetter pattern arrives later in the week.

Sunny Stretch Starts Sunday

Sunday will stay dry under mostly sunny skies, with north winds increasing to 6 to 12 mph. Any river-valley fog should burn off shortly after daybreak, according to the National Weather Service, and no watches, warnings or advisories are posted for the area.

Warmth Builds Through Wednesday

Monday will be mostly sunny with a high near 74, followed by another sunny 75-degree day Tuesday. Wednesday looks a touch warmer, with mostly sunny skies and a high near 77 while rain chances remain close to zero.

The forecast marks a clear improvement from the cloudier and wetter setup outlined in an earlier Hoodline forecast. For now, Columbus gets several good days for walks, patios and outdoor errands before the atmosphere starts adding a little drama.

Rain Chances Return Thursday

Thursday could reach 79 degrees, with mostly cloudy skies and a 50% chance of showers after 8 p.m. Rain chances rise to about 50% Thursday night and Friday, when showers may affect outdoor plans.

Friday will be cooler, with a high near 72, and Saturday may bring showers, with a high near 66. The best stretch for dry outdoor plans runs from Sunday through Wednesday, while late-week events may need a backup plan.
