Odds are in your favor all across the gulf states. As for the road route 10 in La is never usable summer or winter.
We leave NJ on the 2nd. of Jan. I generally do not take on water until I am below the freeze line, NC/SC area. Last year spent the first night in a motel, SC, because 25 degrees and no water was a bit much.
Just look at the weather from Ma to SC a day or so before leaving and make a run for it.
