On Wednesday at 2:15 a.m. a freeze watch was released by the National Weather Service valid from Thursday 11 p.m. until Friday 9 a.m. for McKean County.

The weather service adds, "Sub-freezing temperatures as low as the lower 20s possible Thursday night."

"Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing," states the weather service. "Those with agricultural interests should protect sensitive vegetation."

What to do if there is a freeze watch or warning

Freeze warnings are issued from May to October (but can be extended if necessary), when low temperatures are expected to be 29-32 degrees. If there is a potential for temperatures to fall into these thresholds, a freeze watch may be issued a few days ahead of time.
