According to the UGA Extension Viticulture Blog, Pam Knox, UGA Extension climatologist, said the nights of Oct. 2-4 could see temperatures in the 30s across the Southern Appalachians and into northern Georgia and Alabama.
She said while most places won’t have temperatures that get down to freezing, areas that are frost pockets and prone to frost could freeze. A second outbreak could also happen the second week of October.
It’s still a ways off, so the predictions are likely to change somewhat in strength and timing, but something to keep an eye on if you have tender plants that could be impacted by the cold air.
