Many in Butler County were greeted with thick fog when they left their homes early Friday.
At one point- around 7 a.m.- visibility was reduced to less than a quarter-of-a-mile in some spots.
The fog should burn off by 10 a.m., according to the National Weather Service, and lead way to another hot, summer, humid day.
Temperatures are expected to get into the upper 80s, with dewpoints well into the 60s.
