Get ready. Grab your longjohns out of the closet. See if you can find those winter gloves you stuck somewhere last March. The freeze is coming.

The National Weather Service early today issued a freeze warning for five Western New York counties – Erie, Niagara, Orleans, Genesee and Chautauqua – effective from 11 p.m. tonight to 9 a.m. Tuesday.

Forecasters are calling for overnight lows ranging from 25 to 30 degrees in those five counties.

Why aren’t two more inland counties, Wyoming and Cattaraugus, included? They’ve already had their first freeze.

The timing of the first freeze is pretty much hitting the historic average for most of Western New York.

National Weather Service meteorologist Jim Mitchell said that for the Buffalo area, including most of Erie County, the first freeze tends to fall between Oct. 22 and 29. The first freeze can be a little later for lakeshore areas, a little sooner for inland regions.

“We’re right on target,” Mitchell said.

Those temperatures will kill unprotected sensitive vegetation and bring an end to the growing season, officials warn. So residents in the affected areas are advised to protect such vegetation and either cover potted plants or bring them inside.

“Anybody who’s got anything outside, it most likely will be killed if it’s left outside,” Mitchell said of most of Western New York. “Nothing will survive tonight.”
