Columbus is waking up warm and sticky this Wednesday, July 8, with John Glenn Columbus International Airport clocking clear skies, a temperature near 68°F, and a dew point close to 66°F, which makes the air feel downright muggy. Patchy fog is expected to cut visibility during the early commute before the sun goes to work and clears it out. From there, the city is set to heat up fast, with afternoon highs climbing into the low 90s under mostly sunny skies and light winds.
Foggy Mornings, Hot Afternoons
Localized fog is likely between about 7 and 8 a.m., especially near river valleys and in lower-lying neighborhoods, so drivers should be ready for some quick shifts in visibility. Once that lifts, look for partly sunny conditions for the rest of the day. Humidity will keep it feeling sticky even as the thermometer hits around 90–91°F, and with winds staying light, there will not be much of a breeze to cut the heat. The National Weather Service is calling for an overnight low near 71°F in the Columbus area.
Late-Week Rain And Local Flood Risk
A larger system is on track to move in from Thursday into the weekend, bringing rounds of showers and thunderstorms that could stick around and reintroduce a localized flooding threat. The heaviest rain totals are expected to land south of I-70 but may still clip Columbus. Coverage of a late-June flood-watch setup highlighted how similar patterns can produce ponding on poorly drained streets around the city. If you have outdoor plans from Thursday night through Friday, you will want to build in some flexibility for brief heavy downpours and shifting timing.
Timing And What To Expect
The National Weather Service currently shows only a slight chance of storms Thursday afternoon. Showers and thunderstorms become likely after 2 a.m. Thursday night, with a precipitation chance around 60 percent, jumping to about a 90 percent chance on Friday. Forecast guidance calls for new rainfall amounts between a quarter and a half inch, with the heaviest rain still favored farther south. Even so, slow-moving or training storms over the same spots could quickly stack up higher local totals and lead to brief street or basement flooding. It is worth keeping an eye on any watches or warnings issued by the National Weather Service.
For now, early commuters should be ready for reduced visibility in fog, and anyone with late-week errands or events should plan around the potential for sudden downpours. Do not drive through standing water, and give yourself extra travel time on Friday if the storms line up with your route. If you are organizing outdoor gatherings, consider an indoor backup or a rain date, and check back for updates if flood watches or warnings are posted.
