On Thursday at 1:12 a.m., the National Weather Service issued a freeze watch valid for Friday between 2 a.m. and 9 a.m. for Bucks County. The weather service describes, “Sub-freezing temperatures as low as 31 degrees possible.” “Frost and freeze conditions will kill crops and other sensitive vegetation,” comments the weather service. “Take steps now to protect tender plants from the cold.”
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.
According to the weather service, if a freeze warning or watch is issued for your area, there is little you can do to protect plants. If you can move your sensitive plants inside, do so because the freeze will likely kill them, depending on the severity of conditions.
