Long Island is expected to get a light coating of snow Sunday night into Monday morning that could cause hazardous travel conditions, the National Weather Service said.

The total forecast snowfall is 1 to 2 inches for Long Island and New York City, with the heaviest accumulations on Long Island's South Shore. Snow-and-slush-covered roads could result in slippery travel as temperatures hover in the upper 20s and lower 30s, forecasters said.

Long Island is in for a pattern of thawing and freezing beginning Sunday and lasting much of this week. Temperatures will climb into the high 30s and low 40s during the day and dip just below freezing at night. forecasters said. 

Sunday will be mostly cloudy with a high in the upper 30s or low 40s.

At night, the temperature drops to the high 20s, "with some light snow coming in, late evening into the overnight," according to Bill Goodman, a meteorologist with the NWS in Upton. There will be "minor accumulations, about an inch in most places," he said, though "they may see just a light dusting out on the Forks."

That snow will end Monday as high temperatures reach 38. Tuesday will be a little warmer, about 43, under partly sunny skies, Goodman said.

After that, Goodman said, "we’re going to have a warm front that’s going to park to our south, with low pressure systems passing to the west." That will bring rain to the region Wednesday afternoon and night, and again a 60% to 70% chance of rain Thursday night into Friday.

That rain, and temperatures expected to reach the low 40s in the daytime Wednesday through Friday, should continue to melt the remaining snow.
