Do NOT take I40 this time of year. You WILL run into severe weather. We were just at Kingman and Williams Az and couldn't get to the Petrifed Forest NP. Ridiculous winds and ice. Take I10 all the way to Alabama, then I65 to I85. You want to avoid Tennesse and Kentucky right now. I85 joins I95 at Richmond, Va. Best bet at this time; there aren't any viable better alternatives because of the weather. We are former NJ residents (over 30 years) and moved to Texas in 07; Hopewell near Princeton (there are 2 Hopewells in NJ). Good luck, take care.
