Long Island forecast: Winter storm by Sunday evening but no accumulation

A winter storm will bring rain, possible coastal flooding and sleet to Long Island by Sunday evening, with rising temperatures preventing any buildup, according to the National Weather Service.

High winds are also expected Sunday evening, the weather service said.

Clouds will rise throughout the day with a high in the 30s after Long Islanders woke up Sunday morning to temperatures around 10 degrees. Wind chill overnight could cause it to feel as low as 10 again, according to the weather service.

The storm could start as wet snow, but will quickly turn to rain, said Dominic Ramunni, meteorologist with the weather service. No accumulation is expected as temperatures are expected to hover around 34 overnight.

A high wind warning is in effect for eastern Suffolk County from midnight to 10 a.m. Monday with winds of 30 to 40 mph and gusts of 60 mph.

“It might wake some people up while they’re sleeping tonight,” Ramunni said.

The Met Service issued a coastal flood warning from 7 a.m. to 1 p.m. Monday for northern Nassau and north-west Suffolk. Flooding is also forecast for the East End, particularly along Peconic Bay on the North Fork and southern Nassau, including areas that don’t normally experience flooding, the weather service said.

The bulk of the storm is expected to pass by Monday morning, although residual showers may remain, Ramunni said.

“We’ll rock and roll tonight and clean up tomorrow,” Ramunni said.

Temperatures soar into the 40s on Monday before another blow of cold air arrives on Tuesday.

Tuesday promises to be sunny with a high in the lower 30 degrees. Temperatures are warming up on Wednesday with a high in the mid-40s and Thursday’s high is expected to drop to just above freezing.

Then more cold air could keep temperatures in the 20s for Friday and Saturday, Ramunni said.
