Long Island weather: Winter weather advisory for Suffolk

Winter gear remains a must for at least a week, and the National Weather Service predicts Long Island will see a few inches of snow Saturday.

There is the potential for more record-setting lows as the cold snap that started the day after Christmas keeps temperatures 20 degrees below average.

“It’s getting progressively colder,” said Joe Pollina, a National Weather Service meteorologist based in Upton.

The 2 to 4 inches of snow Suffolk could see Saturday likely will not require much shoveling.

The weather service’s winter weather advisory for the eastern county runs from 10 a.m. to 10 p.m. That “means periods of snow will cause primarily travel difficulties” so drivers are urged to use caution, it said.

Nassau should only get 1 to 3 inches, the service said.

The high Saturday will be a warmer 27 degrees and the low 16.

Sunday brings the chance of setting another record, while the wind chill will range from minus 6 to minus 10, said Pollina.

The thermometer should rise to 19 in Islip, which would break the 1976 record of 22, Pollina said.

New Year’s Eve on Sunday will be particularly brutal for anyone celebrating outside. With lows from 5 to 10 degrees that night, meteorologists say it could make for one of the coldest ball drops in Times Square. On Long Island the low should be around 9 degrees, with wind gusts up to 29 mph, the weather service said.

The high on New Year’s Day is forecast at 18 degrees, below the previous record of 25 set in 2009, Pollina said.

Warming centers have been made available in both Suffolk and Nassau counties to help people who may need assistance in escaping the dangerously cold weather.

There is an upside, however, to all the heavy winter boots, sweaters and coats — especially for post-holiday dieters. To make up for the extra weight, the U.S. Army boosts its provisions for soldiers who are out in the cold — at least 10 percent, by some estimates.
