Mother Nature brought a winter storm with blizzard-like winds, freezing rain and even thundersnow to Long Island in the past week.

Now, forecasters say, she’s bringing back the high winds.

They will be strong enough that the National Weather Service issued a wind advisory, effective from 2 a.m. until 6 p.m. Monday.

The service said late Sunday night that the winds are the result of a powerful nor’easter moving through that could bring blizzard conditions for other parts of the Northeast. While Long Island won’t get the brunt of that storm, it will get the high winds, the service said.

Weather service meteorologist Tim Morrin said vehicles traveling on elevated roads and bridges during Monday’s commutes could be buffeted by winds gusts of up to 50 mph.

“Winds will start to noticeably increase” late Sunday night, said Morrin, who is based in Upton. Sunday night’s gusts were expected to reach 40 mph, he said.

In an 11:32 p.m. statement, the weather service also warned of black ice overnight Sunday night as temperatures dip toward freezing.

That statement said sustained winds Monday will be between 20 and 30 mph with gusts up to 50 mph and the strongest winds are expected to be between sunrise Monday and late Monday afternoon.

Although Monday will be partly sunny with a high temperature of 38 degrees, which is average for this time of year, Morrin said it will feel like it’s 20 to 25 degrees outside due to the wind chill.

Winds will diminish after 6 p.m. Monday to below the wind advisory level, but gusts are still expected to be in the 30 mph range.

On Sunday, Long Islanders saw an all-day wintry mix of freezing rain, sleet and snow — all this on the heels of Thursday’s snowstorm.

About 6/10ths of an inch of snow was recorded at MacArthur Airport in Islip Sunday, Morrin said.

Tuesday will be a very bright but chilly day when highs will be near 39 before clouds return overnight with lows around 30, forecasters said.

A mix of clouds and sun with the possibility of scattered snow showers is ahead on another breezy day on Wednesday, with highs near 40 expected and lows overnight around 28.

Expect a repeat of a mix of sun and clouds for Thursday, when highs will drop off slightly to near 38 and overnight lows will be around 27.
