The freeze warning previously issued for this morning has been canceled.
Overnight temperatures are expected to drop to near or below zero in most areas overnight before climbing back above the freezing point Monday morning.
A frost advisory spanning the Tri-State goes into effect overnight. Tended plants should be protected or brought indoors by Sunday evening, said Environment Canada. That, in turn, will allow temperatures to plummet into the mid-30s and present the possibility for freezing or frost to develop, especially north of Lehigh Valley.
The frost advisory was issued for Southern Erie County, including Orchard Park and Springville, from midnight until 9 a.m. Monday.
To protect frost sensitive plants, cover them with layers of newspapers or blankets.
"There will be a risk of a frost and freeze where skies become clear and winds diminish through Thursday morning and perhaps Friday morning in some locations of the Northeast", according to AccuWeather Senior Meteorologist Alex Sosnowski. Even as the chill eases by midweek, highs in the 60s will still remain several degrees below normal.
The National Weather Service in Grand Rapids says temperatures will fall to 25 to 30 degrees tonight.
