Assuming you mean AR (Arkansas) and not AK (Alaska).
Weather here in TX will be generally warm days and cold to cool nights and the possibility of rain. UQ in the 40* range will likely be OK, but 30* just in case, and tarps a very good idea.
I'm not familiar with Davey Crockett or Angelina, but Sam Houston NF has some very nice spots along the Lone Star Hiking Trail, but you should check for current state of closures of portions of the trail
There is a nice car camping area at Parking Lot #8 with good hiking along the Four Notch Loop. We just got back from a four day trip out there.
You can also camp anywhere on trail. Section 1 also has some nice camping areas on it, and by the time you get here, it should be open all the way to Stubblefield Lake.
