What December feels like

December is one of the two snowiest months here and also when the inversion tends to settle in for the holidays. Temple Square goes up in lights, and the canyon traffic starts before dawn — the trick everyone learns is to be at the mouth ahead of the crowd rather than in it.

Winter is doing its thing: 12.1 in of snow in a typical December, with fresh snow on about 7 days. Nearly every night dips below freezing.
