From Houston to Denver this is a much more direct route and it avoids all mountain passes and most of the high elevation found on a route that takes you to I25 in New Mexico. It is also much shorter. This is US 287 all the way from Houston into Denver. You are less likely to find winter-y weather on this route. Its highest elevation is about 5500' out east of Denver. Note US 287 and I 45 are the same highway on this route in Texas and US 287 and I 70 are the same highway on the this route in Colorado. US 287 is a multi lane highway from Fort Worth to the Colorado state line where it turns into a good wide 2 lane highway. It is the choice of commercial carriers so it carries a lot of truck traffic. I've traveled this route several times and haven't found traffic to be much of a problem once you are out of Houston. You might want to explore ways to go around Fort Worth or alternatively go through during mid day or after 7 PM.
Good Suggestion - the Map - for you to do anytime the weather window is available. Understand the Snow has been a very slight issue this year - BUT - that does not mean you are good to Go, anytime, only when you are sure you have a Clear Weather Window to travel.
I have traveled this route in the winter with Zero Issue - but I have seen the weather hit this route with not only Snow but also Ice!
IMHO this is the easiest and likely the earliest Route to Consider.
