Will you drive I40 or try and go through the NP?? I40 is usually OK but it can be hit or miss depending on temps and precipitation. Also a possibility of black ice if it is cold and heavy frost sets in. Driving through the NP can be trickier with more curves, steeper grades and some of the roads never see the sun.
Best advice is to monitor weather and make a decision. Check highway driving conditions on internet.
