Freeze Warnings and Frost Advisories for Saturday morning issued for all of WNY

Temperatures will fall into the 30s overnight, the first time since May 13th.

BUFFALO, N.Y. — With chilly temperatures, a clear sky and calm winds expected Friday night, frost could develop inland of both Lake Erie and Ontario by Saturday morning. 

The National Weather Service in Buffalo has issued both Frost Advisories and Freeze Warnings for all of Western New York. 

A Freeze Warning is in effect from Midnight to 8 a.m. Saturday for Cattaraugus and Allegany counties. A Freeze Warning is in effect from 1 a.m. to 8 a.m. Saturday for McKean and Potter counties. 

A Frost Advisory is in effect from Midnight to 8 a.m. Saturday for Niagara, Erie, Orleans, Genesee, Wyoming and Chautauqua counties.

Take time Friday evening to cover sensitive outdoor plants or take them inside, if possible. Temperatures are expected to drop into the low-mid 30s everywhere inland of the lakes. And it wouldn't be a bad idea to keep them covered Saturday, as temperatures will be back to nearly the same degree Sunday morning, allowing a second chance for frost development. 

This is will be first official frost of the season, even though Fall doesn't officially begin until 9:31 a.m. Tuesday, September 22nd. These cold weather alerts come two weeks earlier than 2019, though cooler temperatures such as these have arrived much earlier than September 18th. 

But as for Frost Advisories in particular, the National Weather Service in Buffalo says that this is the earliest Frost Advisory to be issued since at least 2001 when they began keeping record. The first frost season usually doesn't arrive until the first week of October.
