As temperatures dip down below freezing, melted snow is causing concern about black ice.
Meteorologist Ryan Hanrahan said temperatures are expected to drop into the 20s overnight, with wind chills in the single digits.
Puddles of snow melt are liable to re-freeze across the state, making for slick travel conditions.
Danbury Mayor Mark Boughton described Clapboard Ridge Road as a "black ice nightmare" and said the area is blocked off until state workers arrive to put down snowmelt.
