Frosty, because it's arid, altitude is the main factor in temperatures in AZ. We're at 5,300 feet, so typical winter highs are 40's to low 50's, lows 19-29. We get 10" of precip every year, some of it as snow. I'd say current conditions are typical for us at this time of year, including snow.
It was somewhat warmer than usual here last summer--more 90 degree days than usual. Yuma's a regular furnace, as are all the low-lying cities in AZ. Our state deserves its reputation as a state where you can get four seasons in one day. Yesterday's state high was 75 in Chandler, 1 in Bellemont.

Just for comparison: we went on an Alaskan cruise last July. Temp never got out of the 40's in Alaska. It was 59 when our ship docked in Seattle. Then we flew to Phoenix--and walked out to 116.
