We're thinking about spending December and part of January in southern California. What kind of weather can we generally expect that time of year traveling from Florida to Borrego Springs and back?
Between San Antonio, TX and Tucson, AZ, there will be a possibility of brief snow/sleet storms that are usually fast moving but make for slick roads for a day or so. Just pay attention to weather reports. you will probably sail right through with no trouble at all.
