Winter isn't done with Long Island yet, as an all-day snowfall is due to move in Wednesday, the National Weather Service said.

Tuesday's high in the low 50s will be dropping Tuesday night to right about the freezing mark, setting the stage for snow.

The latest forecast from the weather service calls for snowfall of anywhere from a half-inch to possibly two inches, starting about 7 a.m. Wednesday, going all day and tapering off by evening.

The snow will be wet and slushy, mixing with rain at times. But there still may be enough to make both commutes a bit slippery, the weather service said in a Tuesday evening advisory.

The weather service said there is also an outside chance for heavier snow.

"There is a low potential for a period of moderate to heavy snow banding for NYC/NJ metro and coast during the mid morning into mid afternoon. If that occurs, a quick 2 to 3" of snowfall with snow covered roads would be possible," the advisory said.

Thursday and Friday should be partly sunny with highs in the mid 40s, but Friday night, rain may arrive, forecasters said. The rain is expected to last through Saturday when the temperature goes up into the 50s, then drops to the 20s, turning the precipitation to snow for a short time.

Sunday looks to be sunny, with a high near 40 and next week looks like a warm-up, the weather service said.
