Long Island weather: Snow could come Wednesday

Long Islanders can expect a sunny Sunday and a rainy Monday before a coastal storm moves in, possibly bringing heavy snow, forecasters said.

Mostly clear weather and temperatures in the 50s are forecast for Sunday before colder temperatures start Monday, according to the National Weather Service.

"For Long Island [on Monday], it looks to be primarily rain. Temperatures should be warm enough. We have highs in the lower 40s," said Faye Morrone, a meteorologist with the weather service in Upton. "In terms of accumulation, we have no snow in the forecast for Long Island. You’d have to go north and west of the city for any accumulation potential."

Tuesday will be mostly sunny, with highs in the upper 30s, the weather service said.

Things could turn around Wednesday, however, when a winter storm is expected to come, though Morrone said Saturday it is too far out to predict a specific amount of snow.

"It’s really too early to tell at this point," she said. "But it’s definitely something to keep an eye on."

The weather service issued a hazardous weather outlook Saturday afternoon, noting the region could see "a significant coastal storm" that could bring heavy snow and/or rain Wednesday and Wednesday night with blustery winds. Coastal flooding is also possible.

The storm track will determine, the weather service said, "if we are looking at a heavy snow event for the entire area, heavy snow for coastal plain and light snow event interior, or a heavy interior snow with snow to rain [on the] coast."

Highs are expected to be in the upper 30s on Wednesday, the weather service said.

Snow may continue — with a 30% chance Thursday. The temperature high will be near 38 degrees. Friday will be mostly sunny with a high near 38 degrees, too.
