The wx will be nice, especially in AZ. highs in the 60's to low 70's in the day, in the 30-40 range at night. High on my list of places to go are Sedona, Vegas and Havasu. California wx may not be quite as nice. More prone to storms, but generally still good. Lots of neat places to go. Be sure to make it down to my home town, San Diego, alot to see and do here. Catalina island is pretty neat, as is Big Bear airport in the mountains east of LA. Both airports usually require special checkouts, so it can be expensive. Chino airport, east of LA is a haven for warbirds in various states of repair, good museum also. Up North is Santa Barbara, a nice sea side tourist community. If you venture farther north, visit Pismo Beach. The name escapes me now, but there is a nice(and short) airport almost on the beach next to it. Monterey a bit further up the coast is nice also. Pebble beach is there if you like to chase the little white ball around. The aquarium is a must see. San Fran is great. Dont know much about GA ops up there . Across from SFO at the base od the Sierras is a neat little airport named pine mountain lake, its been a few years, so I may not be exact on the name. If you are daring, hop the Sierras and go to Mammoth airport. The natural hot springs are really nice as is the town.
You should have a great time, only wish I had the time to do it also
