The NWS informs, "Temperatures as low as 33 degrees will likely result in frost formation."

This advisory is in effect until Sunday at 9 a.m.

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 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.
