Cincinnati woke up today to thick, patchy fog and that familiar wall of summer humidity, with temperatures already in the low 70s before sunrise. Dense pockets of fog cut visibility in parts of the city, especially in some neighborhoods and along riverfront corridors, while motorists around and southeast of I-71 reported visibility that could shift from decent to dicey in a matter of seconds. The fog is expected to thin after sunrise, but it may still slow some early commuters.
Foggy Morning, Sunny Afternoon
By midmorning, the fog should lift and give way to mostly sunny skies and a hot, sticky afternoon. Today's high is forecast to land near 92°F, with heat index values pushing as high as 101°F. Southwest winds will stay on the light side, around 0 to 6 mph, which means the humidity is not going anywhere.
According to the National Weather Service, anyone working or playing outside this afternoon should plan on extra water breaks and some time in the shade.
Evening Thunderstorm Risk
The quieter skies will not necessarily last into the night. Showers and thunderstorms are more likely tonight into early tomorrow morning, with a chance of storms developing around 11 p.m. today and the highest coverage expected between about 2 a.m. and 5 a.m. tomorrow.
The overnight forecast carries an 80% chance of precipitation, with new rainfall amounts of roughly one half to three quarters of an inch possible. Some storms could pack damaging straight-line winds and occasional large hail. Forecasters expect the greatest severe threat to stay to the west, but any stronger cell could bring quick downpours and travel problems. It is a good night to cover or bring inside loose outdoor items before sunset.
Heat Relief and City Resources
With temperatures peaking in the low 90s and humidity running high, residents without air conditioning have options. Cooling centers and Cincinnati Recreation Commission facilities are open as a place to cool off. The City of Cincinnati maintains a list of cooling resources and recreation center locations, along with hours and access details.
If you rely on power-sensitive medical equipment, officials recommend having a plan in place now in case any of the storms lead to brief outages.
Commute Tips
Drivers should expect a slower morning commute where fog lingers and be ready for potential evening delays if storms fire up. Brief, heavy downpours can quickly slow traffic on I-71 and over the river crossings.
On the roads, slow down in low visibility, leave extra room for braking in heavy rain, and keep your phone charged if you are heading to outdoor evening events that could be disrupted by the late-night storm window.
