Seasonable temperatures will feel much colder Saturday as a windchill effect creeps over Long Island, local meteorologists said.

A northwesterly wind will be blowing from 15 to 20 mph with gusts to 30 mph, said Tim Morrin, a meteorologist with the weather service’s Upton bureau. Temperatures Saturday are expected to reach 48 degrees, on par with the normal temperature for this time of year at Long Island MacArthur Airport, Morrin said, but the winds will make it feel as if its in the 30s.

“For today, the good news is that we’ll have bright, bright sunny conditions,” Morrin said. “Temperatures are pretty much spot-on average, right where they should be for this date. But there will be a windchill effect today. It’s probably a good idea to layer some outer layers of clothing before going outside.”

Saturday night will be a clear, starry night, Morrin said, as temperatures drop below freezing and are expected to hit the 30 degree mark.

Justin Godynick, a meteorologist with News 12 Long Island, said a cold front cleared the way for high winds over the Island.

“Overnight, temperatures will be quite chilly, in the upper 30s,” Godynick said. “Stick the wind in with that and it feels like the mid-20s.”

Morrin said the high winds will diminish as the night wears on, “but we’ll still have a noticeable breeze.”

On Sunday, temperatures will drop about 5 degrees for a high around 43, Morrin said, but the winds will lessen significantly.

“We’ll still have the bright sunshine and even though temperatures will be a bit cooler than Saturday, the good news is the wind will be diminished so it won’t be as chilly,” Morrin said.

Dry conditions are expected to persist throughout the weekend, Morrin said.

But scattered showers and a possible snow shower could pop up on Monday, Godynick said. “But it’ll be way too warm for any accumulation,” he said, if snow does fall.

Tuesday “looks quiet and seasonable with a good amount of sunshine,” Godynick said. Wednesday into Thursday could possibly bring “a good soaking rain,” he said.

Looking into the long-range forecast starting about a week from now, Godynick said “we’re expecting the coldest air of the season for the next week or two as some Arctic air shifts in our direction.”

“It’ll be the first widespread cold snap in the whole continental U.S., really,” Godynick said.
