Lawrence woke up to a fog today.
Mike Akulow, a forecaster with the National Weather Service in Topeka, said the fog started developing about midnight and spread as temperatures cooled.
Fog is caused when the air cools close to the ground and humidity is high.
Lawrence and the eastern third of the state were under a dense fog advisory this morning. Akulow expected that the advisory, which was in effect for the eastern side of the Kansas Turnpike from Wichita to Topeka, would be lifted by late this morning. The fog also reached into the Manhattan and Junction City areas.
"Visibility is going up with the higher temperatures," Akulow said.
However, Wichita still had zero visibility at 10:30 a.m. today.
Neither Lawrence nor Douglas County law officers reported any fog-related accidents this morning.
