Long Island forecast: A damp, foggy night with a mix of rain and snow ahead

After a foggy and damp Wednesday night, rain is forecast for Long Island on Thursday before snow, sleet and ice join the mix Friday, the National Weather Service said.

A dense fog advisory remains in effect for Nassau and Suffolk counties until 10 a.m. Thursday, according to the weather service. Visibililty could drop to a quarter mile or less, the advisory said.

The low Wednesday night will drop to 36 degrees with patchy fog and a 30% chance of rain, forecasters said.

"A cold front will move through late Thursday night into Friday with quickly falling temperatures behind it. Rain Thursday night will change to a wintry mix from northwest to southeast, with several hours of freezing rain, sleet, and snow," the weather service said.

In an update later Wednesday, the weather service warned of "dangerous travel conditions … where ice accretes during both the morning and evening commute on Friday." Sleet could mean less ice but flooding is possible because of melting snow combined with rain, according to the update.

Long Island may see between 1.37 inches to 1.41 inches of precipitation through Saturday, the weather service said.

Thursday's daytime high will be near 47, the weather service said. The chance of precipitation is 60%.

Rain, possibly mixed with freezing rain, is predicted for Friday before 3 p.m., followed by sleet, possibly mixed with freezing rain, forecasters said. The temperature will fall to around 30 by 5 p.m. with a north wind 7 to 10 mph and gusts as high as 21 mph. The chance of precipitation is 100%, the weather service said. Little or no ice accumulation expected and new sleet accumulation of less than a half inch possible.

Friday night will have freezing rain, possibly mixed with snow showers and sleet before midnight, then a chance of snow showers and freezing rain between midnight and 1 a.m. The low will be around 18 and the chance of precipitation is 80%. Little or no ice accumulation is expected and new snow and sleet accumulation of less than a half inch possible, the weather service said.
