I am soliciting advice for a trip from Bass Lake, IN located about 60 miles SW of South Bend to Phoenix, AZ in early February.
Specifically I am wondering what weather conditions can be expectd in Amarillo, or other cities locatd in the northern part of OK, TX, NM and AZ. Mapsource is outing me via I-55 to I-44 (St. Louis) to 1-40 (Oaklahoma City) through Albuquerque, NM to I-17 9Flagstaff, AZ) and south to Phoenix.

I know the weather can turn bad anywhere along there but what are the normal temps.

Any info would be greatly appreciated.
