Columbus wakes up Tuesday, June 9, 2026, to muggy, mild air around 73°F at John Glenn Columbus International Airport, and the umbrella is not getting the day off. Showers and thunderstorms are expected to ramp up from late morning into the afternoon, with a high near 83°F and rain chances hanging on into the evening. Brief heavy downpours and gusty winds could slow commutes and cut visibility on area roads.
Afternoon Downpours Likely
Forecasts call for a chance of rain showers before 11 a.m. EDT, followed by increasing showers and thunderstorms through the afternoon, with activity peaking between about noon and 4 p.m. EDT. Most locations are expected to see between a tenth and a quarter of an inch of rain, but any stronger storm could deliver brief, heavier totals and gusty winds, so build extra time into afternoon errands and school or work pickups, according to the National Weather Service.
Late-Night Round Could Bring Heavier Bands
Yet another disturbance may pull together into a cluster of storms late tonight and overnight, with the southern parts of the metro area most likely to be in the path. Widespread flooding is not expected, but pockets of heavier rain are on the table, so residents should keep an eye on conditions before heading to evening events or setting out on overnight travel.
Midweek Heat And Humidity
After Tuesday’s rain, temperatures jump sharply on Wednesday and Thursday. Highs are forecast near 89°F on Wednesday and around 91°F on Thursday, with heat-index values pushing into the upper 90s to near 101°F. If you do not have reliable air conditioning, the City of Columbus offers guidance and cooling options, and outdoor plans are better saved for the cooler morning hours.
Plan Ahead
Secure lightweight outdoor items before storms roll through, and expect slower rush-hour travel with wet roads and reduced visibility. Do not attempt to drive through flooded roadways: turn around, don’t drown. Keep your phone charged, and check local forecasts along with any watches or warnings before heading out for evening plans.
