Alabama will face yet another night of freezing temperatures tonight, and freeze warnings will be in effect for the entire state.

High temperatures today (Sunday) are only expected to make it into the 40s for a large part of Alabama:

Tonight could be the coldest of this spring cold snap, and some spots in north Alabama could see temperatures in the low 20s by Monday morning.

Monday marks the first day of astronomical spring with the equinox (at 4:24 p.m.), but it will feel more like winter for much of Alabama with highs expected to reach only the 50s statewide.

More cold is expected on Monday night into Tuesday morning, but it may not be quite as chilly as tonight is expected to be:

But there’s good news. After Tuesday a warming trend will begin, and most of Alabama could be back in the 80s by Thursday.

Here’s a glimpse of Thursday’s high temperatures:
