Drizzly spring weather could turn into snow flurries late Saturday night and Sunday morning across Long Island, the National Weather Service said.
An intensifying low-pressure system bringing an arctic cold front will send temperatures into the low- to mid-30s as the high-wind warning sets in around midnight, said Carlie Buccola, a meteorologist at the Weather Service’s Upton bureau.
Sustained winds will be 30 to 40 mph with gusts of up to 60 mph, while the snow for Long Island will be a coating to less than an inch, expected to fall between 2 a.m. and 8 a.m.
“Trees and power lines could be downed, bringing scattered power outages. There could be difficulty driving, especially high-profile vehicles like 18-wheeler trucks. You’ll definitely feel the wind gusts as you’re driving,” Buccola said. “If you already put out your lawn furniture, you might want to take it back inside or secure it.”
The threshold for a high-wind warning to go into effect is when sustained winds are expected to top 40 mph, or with gusts of 58 mph or more. No flood watches have been issued, she said.
“The really cold temperatures, those are going to be below average for this time of year, but you can’t rule out snow in April for this area,” Buccola said.
The high winds are expected to last for hours through Sunday morning before they start to taper off in the afternoon, with the warning set to expire at 2 p.m.
The high temperature for the Island is 42 for Sunday; by Monday, it will be back up to 50, Buccola said. Precipitation in the form of rain could come back Wednesday into Thursday.
“It doesn’t look like until toward the end of the week when it’ll start to get nice out again,” Buccola said.
