Windchill advisory in effect overnight, with 'dangerously cold' temperatures, forecasters say

A windchill advisory issued by the National Weather Service is in effect until 8 a.m. Thursday as forecasters warned of "dangerous" cold hitting Long Island.

The temperature at Long Island MacArthur Airport was 11 degrees just after 9 p.m. -- and the wind chill was minus 8.

Brian Ciemnecki, meteorologist at the service's Upton office, said there's a shot at a daily record low temperature Thursday, most likely in the wee morning hours.

"We're calling for a record low of 5 degrees," he said, which would surpass the previous mark of 7 in 2014.

Indeed, the dip is similar to a period last January when five records related to cold temperatures were broken at the airport within the first eight days of the month, according to weather service data.

On Wednesday the cold air combined with strong, shifting winds out of the northwest, from 17 to 25 mph with gusts up to 36 mph, to produce the deep freeze. Gusting winds Wednesday evening at LaGuardia and Kennedy airports were causing delays on arrivals, officials said.
