A frost advisory was released by the National Weather Service on Wednesday at 2:53 p.m. valid for Thursday between midnight and 8 a.m. The advisory is for Northern Saratoga, Northern Washington, Eastern Schenectady, Southern Saratoga, Eastern Albany, Western Rensselaer, Eastern Greene, Western Columbia, Eastern Ulster, Western Dutchess, Eastern Dutchess, Southeast Warren and Southern Washington.

The NWS adds to anticipate, “Temperatures as low as 31 degrees will result in frost formation.”

“Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered,” describes the NWS. “Take steps now to protect tender plants from the cold.”

Frost advisory – this is what it means

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 NWS, 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.
