Friday, June 5, 2026, started out clear and muggy in Cincinnati, with the airport sensor reading about 59°F (15°C) early this morning. Sunshine is expected to rule the afternoon, pushing highs to around 86°F with light southerly breezes and a warm, sticky feel. Tonight stays mild near 68°F. If you are heading out early, plan on extra water and a light layer, since the humidity will make it feel warmer than the thermometer says.
Afternoon Heat, Comfortable Evenings
Most of today should be mostly sunny with that high near 86°F and southerly winds around 1 to 10 mph, so it will be warm but not especially breezy. Skies turn partly cloudy overnight, and temperatures settle near 68°F. Evening plans should be fine, with conditions on the warm and muggy side but short of oppressive.
Storm Chances This Weekend
Forecasters say scattered showers and thunderstorms are possible late tonight and through the weekend, with the first real shot arriving Saturday, June 6, as daytime heating helps to fire up a few late day storms. The better chances come Saturday night into early Sunday, with rain chances around 40 percent Saturday night. Sunday, June 7, is the likeliest day for more widespread showers and thunderstorms at about 60 percent coverage. Some storms Saturday could become strong, with damaging wind as the main concern in any severe cells, though isolated hail or a brief tornado cannot be completely ruled out. For more details, see the National Weather Service forecast.
Air Quality Alert
The Southwest Ohio Air Quality Agency issued an Air Quality Alert on Thursday, June 4, for Butler, Clermont, Hamilton, and Warren counties and surrounding areas, warning that ozone levels "may approach or exceed unhealthy standards." Children, older adults, and people with lung disease are advised to limit prolonged outdoor exertion today. To help cut ozone levels, the agency suggests carpooling, avoiding unnecessary idling, refueling after 8 p.m., and pushing off gas-powered yard work.

Plan Ahead
If you have outdoor events lined up this weekend, it is worth having a backup plan. Mornings and midday hours look like the safest bets for staying dry, while afternoon heating on June 6 and 7 could pop up spotty storms. Commuters should keep an eye on late-day radar for downpours and lightning, as heavier cells may lead to slick roads and minor delays. Anyone with asthma, heart disease, or other respiratory issues should keep strenuous outdoor activity to a minimum today while the air quality alert is in effect.
What To Watch Next Week
Next week is shaping up to be more of the same, with humidity creeping higher and repeat chances for afternoon and evening storms. Highs are forecast to climb back into the upper 80s and possibly the low 90s by Thursday, June 11. For the earlier take and context on this pattern, see our May 30 update, earlier take on this pattern. Keep checking the forecast and air quality updates before locking in any long outdoor plans.
