Long Island Finally Gets Chilly Fall Weather— For Now

After a mostly mild start to the fall season, it may be time for Long Islanders to finally take those warm coats and scarves out of storage for good.

A cold air mass moved into the tri-state area overnight, which means it will finally start to feel like fall on Long Island.

"The coldest airmass of the Fall season so far will be ushered in tonight," the National Weather Service said Monday morning. "Frosty conditions are expected across far outlying areas as temperatures drop into the lower to mid 30s."

Temperatures will reach a high in the upper 50s.

A frost advisory was issued for parts of northern New Jersey, the Hudson Valley and Connecticut, though Long Island just missed out on that designation.

Tuesday will feature plenty of sunshine and weaker winds, but temperatures will still remain slightly below seasonable," the government forecasters said. "High pressure will remain over the region into mid-week, keeping conditions dry, with moderating temperatures."

By Wednesday, things will start to warm up again, with highs for the rest of the week in the low 70s and highs in the mid 50s.
