Frost advisory for part of Pennsylvania for Friday

A frost advisory was issued by the National Weather Service on Thursday at 4:18 p.m. valid for Friday between 2 a.m. and 8 a.m. for Southern Centre, Southern Clinton and Southern Lycoming as well as Huntingdon, Perry, Cumberland and Adams counties.

The weather service adds, "Temperatures falling to the mid 30s will result in frost formation."

"Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered," adds the weather service. "Cover or bring inside any plants you wish to keep growing."

What to do if there is a frost advisory Frost advisories are issued from May to October (but can be extended if necessary) when temperatures, winds, and sky cover are favorable for frost development. This is most likely to happen when the temperature is 36 degrees or less. In some cases, the frost is severe enough to end the growing season and is then referred to as a 'killing frost'.

According to the weather service, if a frost advisory is issued for your area, cover up sensitive plants before the sun sets so that it can help retain heat near the plants, or move the plants indoors for the night, if possible.
