What December feels like
Winter arrives properly and the town handles it — plows out early, snow tires on everything, chains in the trunk for the drive up to Snowbowl. Storms can close I-17 and I-40 for stretches; if you are driving up from the desert, check ADOT before you leave rather than after.
Winter is doing its thing: 18.5 in of snow in a typical December, with fresh snow on about 6 days. Nearly every night dips below freezing.
