Frost Advisory Issued for Saturday Morning

The first Frost Advisory of the spring growing season has been issued by the NWS Offices in Huntsville and Birmingham for Saturday morning.

All of Huntsville’s counties are included and the following counties in Birmingham’s area of responsibility:
Blount, Calhoun, Cherokee, Clay, Cleburne, Etowah, Fayette, Jefferson, Lamar, Marion, Randolph, St. Clair, Talladega, Walker and Winston. It is in effect from 3 a.m. until 7 a.m. CST Saturday morning.

Temperatures across the area will fall into the lower and middle 30s. Frost will form, which could harm tender vegetation.

Our frost advisories are part of a larger suite of frost advisories and freeze warnings across the Southeast.

Winter storm warnings are in effect for much of western North Carolina for Saturday night and Sunday morning for 4-5 inches of snow and some 6-8 inch accumulations above 5000 feet. The foothills and Piedmont of North Carolina will pick up 1-3 inches of snow.

SIDE NOTE
Did you ever wonder why the NWS doesn’t issue frost and freeze alerts during the middle of winter?

In the fall, the NWS Birmingham issues frost advisories and freeze watches/warnings until Thanksgiving or until the first significant freeze, whichever comes first. A significant freeze is defined as area wide temperatures of 28 degrees or colder.

In late winter, Birmingham starts issuing the frost and freeze products on March 15th. According to Jody Aaron: “Since we have had a warmer than typical winter and in many places the growing season has already begun, we will begin the program immediately with an impending frost or freeze by the weekend and an fairly widespread frost or freeze by the morning of March 15.”
