It won't be snow tough.

When the flakes start sneaking back as we sleep, Nassau and western Suffolk could get 1 to 2 inches at most, while the rest of Suffolk may see up to 3 inches, according to meteorologists from News 12 Long Island and the National Weather Service.

"Most of what accumulates will be on grassy surfaces and not roads," said News 12 meteorologist Bill Korbel. "Nothing really bad, but any snow this time of year is, while not unheard of, a bit unusual."

A mix of rain and snow Saturday will likely change to all snow late in the afternoon, he said.

Islip and points east will get most of the snow, expected to stop falling by 9 p.m., Korbel said.

Snow showers could fall as early as 2 a.m. Saturday, then appear on and off during the day time, ending before 8 p.m., said meteorologist Faye Barthold at the National Weather Service in Upton.

There won't even be a "brunt of the storm," she said. "It's not supposed to be a huge event," she said.

This late snow in early spring can be blamed one thing: "We still have unusually cold air," Barthold said.

Saturday's daytime high will be in the upper 30s or lower 40s, but night time lows will be in the lower to mid 20s, said.

That's about 10 to 15 degrees below normal, she said.

Barthold forecasts a sunny Sunday, with highs in the 40s, followed by nighttime lows in the upper 20s.
