It's a cold and blustery Monday on Long Island, and light snow's likely on the way, forecasters say.
A fast-moving clipper system pushes into the Northeast starting late Monday, bringing wind-whipped cold and possibly 1 to 2 inches of snow Tuesday, the National Weather Service in Upton said.
High winds on Monday already were causing delays on arrivals at LaGuardia and Kennedy airports, according to the Federal Aviation Administration. Winds at Kennedy and LaGuardia were gusting into the 30-mph range by midafternoon, according to the weather service.
The wind chill was in the mid 20s at both airports as of 3 p.m.
Afterward, an arctic air mass moves in, followed by another clipper low from the north on Friday.
The result is cold air settling in for the week, with temperatures ranging from the mid teens to low 20s. Wednesday is expected to be the coldest day in the stretch, with nighttime lows in single digits.
Wind chill values throughout the week will make temperatures seem even colder.
Nassau County officials said Monday they are preparing for the winter chill and snow with a brine operation on main roads, bridges and overpasses.
The county's Department of Public Works will brine in two phases, starting with roads at 2 p.m. Monday, followed by bridges and overpasses at 4 a.m. Tuesday.
The county also will have 90 snow trucks ready to go, with 16,000 tons of salt on hand.
County Executive Edward Mangano also issued a winter safety checklist, designed to guide residents on ways to cope with the expected winter freeze. Tips can be found at www.nassaucountyny.gov.
Monday's forecast calls for dry conditions, partly sunny skies and highs in the mid 30s, with a blustery west wind 22 to 26 mph gusting at times to 36 mph.
Light snow enters the picture Tuesday, as increasing clouds drop daytime lows to the mid 20s. Wind chill values again play a role; expect it to feel like between 10 and 15 degrees, as a northwest wind blows from 9 to 18 mph.
The service said snow is likely, mainly after noon; chance of precipitation is 70 percent. The Upton office forecasts 1 to 2 inches of snow likely to fall between noon and 9 p.m. Tuesday.
Snow showers are possible Wednesday and Thursday, with chance of precipitation ranging from 20 percent to 30 percent.
By Thursday night, conditions dry but the cold remains until the start of the weekend.
Skies turn sunny and clear and temperatures rise into the low 30s starting Friday, the service said.
