While the heart of the "cold air" is starting to exit northeast, the very dry air mass in place will take several days to do the same. That means we still have some chilly mornings ahead and the threat for frost, especially across east Alabama counties on Monday morning.
A frost advisory goes into in effect from 1am Monday through 8am for the following counties: Lamar, Marion, Fayette, Walker, Winston, Cullman, Blount, St. Clair, Etowah, Calhoun, Cherokee, Talladega, Cleburne, Clay and Randolph. Even if your location is not under an advisory, you still could see some patchy frost which means it's a good idea to protect sensitive outdoor plants.
Here's a look at the projected low temperatures. You'll notice the coldest air will be located across east Alabama.
The cold air mass isn't going to be hanging around much longer. It will slowly lift into Canada the rest of today.
The jet stream will move such that warmer air parked to the west slowly builds in this week and highs in the 80s will be likely by Thursday.
Next possible cold front? Maybe around the 27th
Next possible rain maker? Maybe around the 30th if a Gulf low truly develops and tracks our way
Have a great rest of the day,
