Pouring concrete with cold weather coming

I'm getting my concrete driveway and sidewalks replaced this week. I live in Metairie.
The contractor is going to tear out and form on Tuesday and Wednesday and has scheduled the concrete company to deliver the concrete early Thursday AM.
The current forecast calls for temps in the 50s on Thursday, with the low temp of 30 on Friday morning.
Will these conditions allow the concrete to properly set?
School me on concrete pouring in cold temps. I Googled but all I can find is info on pouring concrete in places up North where the temps are a lot colder and the below freezing duration is a lot longer.

You’re good. Rain is the only thing that would be an issue but that’s just for the initial set up time.

Don’t let them strip forms the next day. Wait a couple days.

You'll be more than fine pouring concrete when temps are in the 40's and above. Soil temps in Louisiana are still in the mid 50's.
As long he doesn't pour in the middle of a thunderstorm or right before and leaves it uncovered a 4-6" slab (driveway and sidewalk) will be fine. You'll be able to walk on it within hours with temps in the 60's.
The main thing I would watch out for and talk with the contractor on is weather Thursday.

Pouring concrete with cold weather
as long as its above freezing you are ok, the issue is how fast or slow it dries on you. if it dries too fast it will crack. in cold weather its often low humidity so it dries faster and needs more watering to prevent cracking. so double up how many times a day and how long you wet the slab down, to account for the faster drying times

Concrete can be a bit weaker when poured in the winter. Cold weather slows down the chemical reaction of concrete and it takes longer to set up and cure. Concrete creates it's own heat with the chemical reaction so low 30s is not generally a big problem but not ideal either.
You need to consider covering it to help hold in the heat so the chemical reactions can take place over a longer period of time. Longer bonding chains = higher strength.

Ask your concrete guy to add some sugar as it's coming down the chute. He's going to act surprised at first, but only because it's a trade secret.

It will cure slower but should stay warm enough, especially since it will be in contact with the earth. Leave the forms for as long as possible (I'd recommend at least 3 days).
Around BR the only time we have issues is for elevated decks and then it has to stay at 40 or below for 3 days. Most of the time contractors will reschedule because they would have to enclose the structure (which is just structure at this point) and bring in heaters under the metal deck.

When I poured the slab for my home in January it had to be postponed because of below freezing temps. Concrete contractor wouldn’t pour in freezing temps.

Wet ground from heavy rains, fairly cold temps, not a lot of sun over last few days leading up to your pour then pouring concrete that morning with below freezing temps over night could create a problem. I wouldn’t chance it

Poured a 10x12 today! Only window I had. Supposed be in the teens tomorrow night. Will cover with plastic and hay tomorrow and see how it goes.

I saw a driveway being poured yesterday and I wondered about it with the low getting down to 4 tonight here in north MS
