Temp wise Feb/Mar should be good. But the weather on our deserts is a******shoot at best. One day it can be 90, the next 30. We have had snow in March...so you just never know.
I think I would probably push for more like Mar/Apr. May will be getting into the 90's pretty steadily without much chance of occasional cold weather.
We typically leave the desert and head for the Oregon coast in mid May as by that time it's starting to get serious about 100 degrees.
Hope this helps
