Alabama will warm up a bit today, but it will remain very cold, with highs only expected to make it into the 30s for the northern half of the state. South Alabama is forecast to climb into the 40s (today’s forecast highs are at the top of this post).

Tonight will be very cold, but not as cold as Wednesday. Here are tonight’s forecast low temperatures:

Thursday’s highs will be a bit warmer than today, but the warmup will only be short-lived.

The weather service is expecting another shot of arctic air to arrive in Alabama starting on Thursday night. Wintry precipitation isn’t expected to be a big issue with this system, but it will send temperatures back into really cold territory this weekend.

Here are the forecast highs for Friday:

Low temperatures by Saturday morning could wind up in the single digits again in parts of Alabama:

Sunday will also have really cold low temperatures, but the weather service expects a warmup to begin on Monday, when highs are forecast to be back in the 40s and 50s across the state. Here are the forecast highs for Monday:

The warmup is expected to continue into next week.
