Clear, cold weather for Wednesday lighting ceremonies in Flanders, Rockefeller Center

If you’re planning to watch the holiday lighting ceremony Wednesday at The Big Duck in Flanders — or the tree lighting at Rockefeller Center, 77 miles to the west — you’re going to need to bundle up.

The National Weather Service is calling for a high temperature Wednesday of 40 degrees in Manhattan and 38 degrees in Flanders.

Overnight temperatures late Wednesday into Thursday will dip into the low 30s — and, in Flanders, maybe even into the high 20s — forecasters said. And wind chills from gusty breezes will make it feel even colder.

The good news? No rain, no snow, no sleet, no hail.

The weather service is calling for sunny skies through Thursday before possible rain Friday. But temperatures fluctuate during the week, ranging from Monday's high in the low 50s to a high in the upper 30s Tuesday and Wednesday, and then back into the upper 40s Thursday and 54 degrees Friday.

And you can expect steady, gusty winds Tuesday and Wednesday, the weather service said.

The weather service has issued a small-craft advisory for all Long Island waters, including Long Island Sound and all South Shore inlets and bays, until 6 a.m. Tuesday.

A gale warning is also in effect for all Atlantic Ocean waters from Sandy Hook, New Jersey, to Montauk Point from 10 a.m. Tuesday until 4 a.m. on Wednesday, the weather service said.
