Looks like we'll have to crank the heat again tonight. Temps are going to fall into the mid 40s in Memphis and mid to upper 30s east of Shelby. From Fayette and Marshall counties eastward, a frost advisory tonight means the plants may take a beating. May want to pull in anything you want to live.
The good news is temps get back into the 70s tomorrow, and will feel pretty good for the rest of the week.
