CoCoRaHS observers in Blue Ridge and Rabun Gap, Georgia, in the far northern part of the state commented on frost in their area overnight. Sunday night into Monday morning will probably be even a little colder than last night. The NWS has issued a series of frost advisories (light blue) and freeze warnings (dark blue) in the map below. So if you like in northern reaches of the Southeast, especially if you are in a mountainous area or valley with cold air drainage, you should protect your tender plants carefully.
I’ve include the NWS graphical forecast of low temperatures for the Peachtree City NWS office for tomorrow morning. If you are in a different area, you can go to your local office’s home page and look for Graphical Forecasts on the left menu. Frost is also likely Tuesday morning in the same locations.
