Cincinnati woke up under a thin veil of fog Thursday morning, with readings in the mid-50s at Lunken Field. The gray start will not last long, forecasters say the fog should burn off by mid-morning, letting bright sun send temperatures into the mid-to-upper 80s this afternoon.
Afternoon Heat And Light Winds
According to the National Weather Service Wilmington, today’s high should land near 86°F with barely-there south winds around 0 to 5 mph. Skies stay mostly clear tonight with a low near 62°F. Friday looks like a near repeat, with highs in the mid-80s as a weak ridge keeps things dry through the rest of the workweek.
Air Quality Alert Through Tonight
An Air Quality Alert is posted until midnight EDT for Butler, Clermont, Hamilton, and Warren counties in Ohio, Boone, Campbell, and Kenton counties in Kentucky, and Dearborn County in Indiana. Ozone levels may approach unhealthy standards, so people with lung or heart conditions, older adults, children, and outdoor workers are urged to limit long stretches of outdoor activity and shift what they can indoors. Officials also recommend refueling vehicles after 8 p.m., avoiding idling and holding off on gas-powered lawn work. The Southwest Ohio Air Quality Agency has full guidance and hourly AQI updates.
Weekend Thunder Chances
Return flow from the southwest will crank up the humidity this weekend, making showers and thunderstorms more likely by Saturday afternoon, June 6, 2026. There is a slight chance after 2 p.m., with coverage increasing Saturday night into Sunday, June 7, 2026. Most storms are expected to be garden-variety summer pop-ups with brief heavy downpours and lightning, although the exact timing and coverage are still uncertain.
Plan Accordingly
Morning fog could slow a few early commutes but should clear before the mid-morning rush, leaving heat as the main story for the rest of the day. If you have respiratory or heart issues, take the Air Quality Alert seriously, avoid strenuous outdoor activity this afternoon and evening, and review yesterday’s sun-soaked setup for more context. Keep an eye on updates from the National Weather Service as the weekend storm timing comes into better focus.
