Columbus woke up clear and chilly Tuesday morning, April 21, 2026, with temperatures around 39°F and patchy frost in low-lying spots. A Frost Advisory is in effect through 10 a.m., so tender plants left outside may be damaged. The cold start will not last long, though, with temperatures expected to jump quickly into the mid 70s and winds cranking up this afternoon.
Afternoon Winds Pick Up
South winds of 6–20 mph with gusts up to 30 mph are expected this afternoon, and the stronger gusts could rattle patio furniture and umbrellas. A tightening pressure gradient will lead to decent mixing and those gusts late in the day, so it is a good idea to secure loose items and use caution if you are driving larger vehicles. For background on the week’s sharp temperature swing, see our earlier look at how a local freeze hits before 80s return.
Tonight: Showers And Thunderstorms Possible
Scattered showers and a chance of thunderstorms are expected late Tuesday night, with the highest odds between about 11 p.m. and 2 a.m. Most of central Ohio should see only light rain, but a brief heavy downpour or an isolated gusty thunderstorm cannot be ruled out. Plan to move outdoor evening plans indoors if possible and keep an eye on radar if you will be on the road late.
Rest Of Week: Warm With Scattered Showers
Wednesday looks mild with a high near 74°F, and the warmest stretch arrives Thursday and Friday when highs push toward 80–82°F. Additional rounds of showers and a few thunderstorms are possible Friday night into Saturday, though widespread heavy rain is not expected at this time. If you have outdoor projects, Thursday morning currently offers the best shot at dry weather.
Gardening And Travel Tips
Gardeners should cover or bring sensitive plants inside through 10 a.m. Tuesday to avoid frost damage. Secure outdoor furniture ahead of the afternoon gusts, and be prepared for brief heavy rain and sudden wind gusts on late-night drives.
