FAIRFIELD COUNTY, Conn. -- The thick fog enveloping Fairfield County on Monday morning will give way to rapidly falling temperatures throughout the day and a deep freeze late Monday night, the National Weather Service warned.

A Dense Fog Advisory remained in place through the morning commute until 10 a.m. Monday across all of the tri-state area, the weather service said.

The dense fog was lowering visibility to a quarter mile or less, creating hazardous travel conditions. Drivers were cautioned to slow down, use low beams and leave plenty of distance ahead if a sudden stop is needed.

The rain and drizzle was expected to continue Monday morning after temperatures rose into the 40s and 50s before dawn.

But then the weather will do a complete about-face, with temperatures falling rapidly into the mid-30s by 5 p.m. and to single-digits by Monday night, the National Weather Service said.

A Wind Chill Advisory will be in effect from midnight until 6 p.m. Tuesday, Jan. 7, the weather service said, with dangerous wind chills expected across Fairfield County and the entire metro area.

The low temperature near 5 degrees combined with heavy winds will cause dangerous cold and wind chills as low as -15, the weather service said. Westerly winds will be 15 to 25 mph with gusts of up to 45 mph.

Prolonged exposure to bitter cold and wind could lead to frostbite and hypothermia. People should bundle up and wear hats and gloves when outdoors.

Temperatures on a sunny Tuesday will hit only about 10 degrees with strong winds and the Wind Chill Advisory continuing as the deep freeze returns to the area.

Tuesday night will be mostly clear, with a low of about 2 degrees and winds of 10 to 15 mph causing wind chills as low as -15.

Experts offer tips here on The Daily Voice on how to protect yourself from frostbite and hypothermia and how to recognize the symptoms of both.
