Cincinnati woke up muggy and murky today, July 19, with patchy fog and mist trimming visibility near Lunken Field. Early temperatures hovered around 72°F, and humidity sat in the mid 90s, keeping things sticky before sunrise. Low clouds are expected to thin through midmorning as the sun breaks out and readings climb into the upper 80s by late afternoon.

Afternoon Outlook

By this afternoon, expect mostly sunny skies and a high near 87°F, with a light north breeze around 2 to 6 mph. Smoke drifting south from distant wildfires could leave the sky looking hazy and may knock visibility down at times. People with breathing problems should take it easy outdoors, according to the National Weather Service.

Air Quality And Health

An Air Quality Alert remains in effect through tomorrow night for parts of the region. Residents with asthma, COPD, heart disease, and older adults are advised to limit prolonged outdoor exertion until conditions improve. For hourly AQI readings and local guidance, check the Southwest Ohio Air Quality Agency.

Storms Tuesday

A stronger cold front is set to move through on Tuesday, July 21, pushing the high to around 90°F and bringing a high chance of showers and thunderstorms during the day. Widespread storms are likely and could bring gusts up to about 22 mph and locally heavy rain in the range of roughly a half to three-quarters of an inch. A few storms could reach brief severe levels, according to the National Weather Service.

What To Expect And How To Prepare

Morning fog may slow river-valley commutes, so allow a little extra time if you are heading out early. Smoky haze this afternoon could make outdoor exercise uncomfortable for sensitive groups, so consider rescheduling strenuous activity or moving it indoors. Keep water and shade handy as temperatures climb later in the day, and have a backup plan to delay or move outdoor events on Tuesday if thunderstorms line up with your schedule. Be sure to monitor local forecasts and air quality updates before you head outside.
