Cold(er) arctic air is going to filter into the Gulf Coast region late this weekend into early next week.
A trough is going to dig into the Central/Eastern part of the country tomorrow, bringing a cold front east across the entire Gulf Coast in tandem with it.
Some rain and storms will be likely along the front, but severe weather is unlikely; much colder air will push in behind it, dropping temperatures well below normal – likely by at least 4 to 8 degrees (Fahrenheit).
The coldest night/morning will be Sunday night going into Monday morning, with temperatures ranging from the mid to upper 30s to lower to mid 40s for most of the North- Central Gulf Coast. Lower 30s will be likely across Northern Mississippi and Alabama.
Thanksgiving Day
Model guidance has started advertising a upper-level cut-off low to develop over over Texas Wednesday, then slowly drift across the North-Central Gulf Coast Thursday and Friday, and for a surface low to develop in association with it.
If this were to occur, it would result in widespread rain and storms across the North-Central Gulf Coast from Wednesday through Friday. However, there is still some uncertainty. We will need to see if models stay consistent with this solution to become confident in it coming to fruition.
In regard to temperatures, there will be a gradual moderation starting Tuesday, and they should be at or near seasonal levels by Thanksgiving Day.
