FAIRFIELD COUNTY, Conn. -- With rain and freezing rain moving into Fairfield County early Thursday evening, the National Weather Service warned of dense fog forming overnight.
A Dense Fog Advisory will be in effect from midnight until 10 a.m. Friday, as rain and freezing rain continue to fall into the morning commute, the weather service said.
Visibility will be limited to a quarter mile or less across southern Connecticut, the Hudson River Valley, New York City, Long Island and northern New Jersey with the widespread dense fog.
The dense fog will make travel difficult overnight and through the Friday morning commute. Motorists are advised to slow down, use low-beam headlights and leave plenty of distance ahead in case a sudden stop is needed.
As a warm front moves northeast toward the area, southeast winds will transport mild, moist air across the colder waters of the Atlantic Ocean and over the deep snowpack, the National Weather Service said.
This will cause dense fog to form after midnight. It will lift after sunrise when the warm front passes through the area.
Rain will continue early Friday, possibly mixing with freezing drizzle before 10 a.m. Showers will continue through the day with thunderstorms possible. High temperatures will be near 50. The storms could produce gusty winds and heavy rain. Up to a half-inch of rain could fall.
The rain will melt more snow and could lead to huge puddles and flooding due to the heavy snowpack and icepack from this winter's frequent snowstorms.
More melting will occur Saturday with highs near 50 and mostly sunny skies.
Sunday brings a chance of afternoon showers and evening snow.
