CHICAGO — Anyone in the Chicago area looking out a window or trying to hail a cab Tuesday is probably having a hard time.
A Dense Fog Advisory was issued for Cook and Lake Counties Tuesday that began around 2:40 p.m. and is expected to linger into mid-to-late-Wednesday morning, around 11 a.m., according to Ricky Castro, a spokesman for the National Weather Service.

"There's a lot of moisture and high humidity," Castro said. "When that kind of pushes up against that marine air mass, fog oftentimes can be the result."

Karen Pride, a spokeswoman with the Chicago Department of Aviation, said despite the fog, "there have been normal operations throughout the day," and was unaware of any flight cancellations. Pride said flights that are canceled or rescheduled are up to the indivdual airlines.
