The forecast for Friday is mostly clear and dry, with highs in the low 40s -- about 5 to 10 degrees below normal, the National Weather Service said.

It was 35 degrees by late morning at Long Island MacArthur Airport, though earlier temperatures of 20 to 30 degrees across much of the Island had prompted a special weather statement about possible black ice.

Clouds will move into the area later Friday, when precipitation comes into the forecast that could last most of the weekend, the service said.

Periods of rain, heavy at times, are expected Saturday, according to News 12 Long Island meteorologist Rich Hoffman. About a half-inch to an inch of rain is expected along with high temperatures near 48 degrees.

Overnight into Sunday, conditions will be mostly cloudy with some scattered showers, Hoffman said. There's a chance of more precipitation early Sunday, and with lows near 33, an early snow shower is possible.
