[1:50 PM] The sky continues to be obscured by dispersed smoke which has filtered into the Ohio Valley from the west. This will continue to create a hazy shade to our summer sky and make stargazing particularly difficult. We should see the smoky skies improve by Thursday. pic.twitter.com/kl5wTyHKsC

Some states, such as Wisconsin and New York, were placed on Air Quality Alert due to the smoke.
As of Wednesday morning, the U.S. Environmental Protection Agency’s AirNow listed most of southwest Ohio’s air quality as moderate, but the Dayton area’s as unhealthy for sensitive groups. People with heart or lung disease, older adults are advised to shorten how long they active outdoors, chose less strenuous activities and wait to be active outside once the air quality improves, according to AirNow.
