Long Islanders are in for a roller-coaster ride as rain, sleet and snow will arrive early Saturday and last through the day, with temperatures dropping into the 20s before the skies clear and warmer weather arrives, the National Weather Service said.

The Island is in for some nasty weather, as a wind advisory will be in effect starting 11 a.m. Saturday and last through midnight Sunday with snow and sleet accumulations of less than one inch expected, the weather service said Friday afternoon.

The weather arriving on the Island on Saturday dwindles in comparison to the “bomb cyclone” snow that the National Weather Service said would threaten the Eastern Seaboard on Friday night into Saturday.

Instead, the Island is expected to see rain arriving around 4 a.m. Saturday with wind speeds starting between 5 to 8 mph, the weather service said. A mixture of rain and snow will start after 1 p.m. and with it, the wind increases to 24 to 29 mph.

Expect wind gusts approaching 50 mph in some areas, leading to the strong possibility of downed trees and wires, as well as for hazardous road conditions, the weather service said.

Wind chill values will make temperatures feel between 15 and 25 degrees Saturday, with winds growing in intensity as the day develops. Sleet could be heavy at times, the weather service said.

Temperatures will plummet throughout the day, falling to about 20 degrees by evening as the snow ends, the weather service said.

Strong winds will continue into Sunday, when the wind chill will make it feel like temperatures are in the single digits despite sunny skies. Temperatures could reach a high of 37.

A gale warning is in effect for all Long Island waters from 10 a.m. Saturday until 7 a.m. Sunday. East of Montauk, that warning will be in effect from 1 p.m. Saturday until 5 p.m. Sunday.

Monday will bring sunny skies and temperatures of around 50 degrees that will continue on Tuesday, the weather service said.
