Columbus started today under clear skies and muggy air, with early temperatures lingering in the upper 60s to low 70s. The warm-up will be quick, with highs near 91°F expected today and readings climbing each day through the week into much hotter territory by midweek.

Afternoon Sizzle And Midweek Peak

Today stays mostly sunny with a light northeast breeze and an afternoon high around 91°F. The real heat ramps up tomorrow and Wednesday, with forecasts calling for about 94°F tomorrow and near 97°F on Wednesday. Heat indices could push toward 100°F, according to the National Weather Service Wilmington, so outdoor plans may feel a lot more punishing than the thermometer alone suggests.

How To Stay Cool

Humidity will rise through the day, with dew points climbing toward the 70°F range, which will make the afternoon feel extra sticky. If you do not have reliable air conditioning, the City of Columbus is operating cooling centers across town, with locations available on the city map or by calling 311, according to the City of Columbus. Bring water, keep an eye on pets and vulnerable neighbors, and try to avoid strenuous outdoor work during the hottest part of the day.

Showers, Commutes And What To Watch

Most of the week looks dry, which is good news for commuters and outdoor events, but there is a slight chance of afternoon storms late Friday and a better chance of scattered showers and thunderstorms over the weekend, with Saturday carrying the highest odds. Overnight temperatures will not offer much relief, holding in the low to mid-70s, so it is smart to schedule outdoor activities for the cooler mornings or evenings and keep hydration close at hand.
