I've got two months off from mid-March to mid-May this coming spring for a road trip. I'm driving down from Alaska and heading for warmer weather (trust me, no matter how cold it may be in the lower 48 it will still be warmer weather to me). But I'm having trouble figuring out what weather will be like around then on average in, well everywhere, but specifically California, Arizona, New Mexico, Utah, Colorado where I am loosely planning on spending the majority of my time. I can play with my departure dates as much as I want but I must be back in Fairbanks by the 25th of May at the absolute latest. Mostly I'll be sleeping in my car (not in AK or Canada when I head down to the states). That is what I did when I road tripped through Canada and northern USA last Sept/Oct/Nov so I'm used to sleeping out in the cold, but . . . Any suggestions on where to go, weather concerns, if I can find me some spring happening along the way and where.
