FAIRFIELD COUNTY, Conn. — After a dreary day, patchy dense fog will develop late Monday night across Fairfield County, potentially causing hazardous driving conditions through the Tuesday morning commute, the National Weather Service said.
A Dense Fog Advisory is in effect from midnight until noon Tuesday.
Visibilities will be a quarter-mile or less at times, which could make travel difficult.

There is also a chance of sprinkles or light rain overnight. More widespread rain is possible again throughout Tuesday with high temperatures near near 51 degrees. The chance of precipitation is 60 percent.
