Long Island weather: Wind chill temperatures below zero Thursday

A wind chill advisory will be in effect from midnight until 10 a.m. Thursday, and there's a potential Thursday morning for a few Sound-effect flurries across the East End.

Wind chill temperatures were expected to sink to 10 to 15 degrees below zero Thursday, a day after a snow squall disrupted the evening commute and brought brief but tense moments of whiteout conditions.

Traffic on the Long Island Expressway crawled Wednesday as the squall dumped less than an inch of snow, which was whipped by wind gusts as high as 45 mph just before 5 p.m., creating whiteout conditions, meteorologists said.

The squall moved at about 40 to 45 mph and it was over in less than half an hour, but the snow was expected to create icy and black ice conditions overnight, said meteorologist Brian Ciemnecki at the National Weather Service's Upton office.

"It kind of came and went," Ciemnecki said. "The squall came through with an Arctic front and behind the front are the cold temperatures."

Nassau and Suffolk police said they had no reports of serious crashes and problems due to the weather.

But still, the cold and winds disrupted power supply to about 4,400 Long Islanders Wednesday and prompted PSEG Long Island and Long Island Rail Road crews to remain on alert.

The LIRR said waiting rooms will remain open round-the-clock through Friday. The LIRR warned riders to be cautious at stations and monitor train schedule changes.

Agency spokesman Chris McKniff said it is taking weather-related precautions through Friday, or whenever the bitter cold ends: ”We have prepositioned crews to be able to repair any weather-related issues, such as broken rails."

Airlines had warned travelers to check their flights if flying out of LaGuardia or Kennedy airports on Wednesday, especially for flights to the Midwest, where the deep freeze has been deadly. The Federal Aviation Administration Wednesday night reported average weather-related delays of 88 minutes at Kennedy and more than two hours at LaGuardia.

Temperatures were expected to fall overnight, and with a wind chill advisory in effect from midnight until 10 a.m. Thursday, Long Islanders might wish they could stay in bed.

Thursday's high is expected to be 17 degrees and the night time low is expected to be 7 degrees, the weather service said.

There’s also the potential Thursday morning for a few Sound-effect flurries across the East End, produced over Long Island Sound, News 12 Long Island meteorologist Pat Cavlin said.

While the normal daily highs and lows for January at MacArthur Airport are 38 to 39 degrees and 23 to 24 degrees, the month is certainly no stranger to biting cold days.

In fact, Monday last week, Martin Luther King Jr. Day, averaged out at 20 degrees below normal, with a 6-degree morning low and 14-degree high later in the day.

As for Friday, the first day of February, look for early morning lows of 6 degrees or so. Temperatures are expected to rise to the low 20s, with early morning lows Saturday in the midteens.

Temperatures recover by Saturday, Cavlin said, heading up to the low 30s, as Sunday and Monday are looking at the low to mid-40s.

“By next week,” he said, “we’ll be in the 50s with shower chances.”
