Wow, the high desert really doesn’t mess around when it comes to changing seasons. The atmosphere is thin and there aren’t any bodies of water to absorb and retain heat over time, so once the sun fades the temperature plummets. Last week we were still seeing temperatures in the high eighties and running the AC a bit each afternoon. Now the forecast shows highs in the sixties from here on out—a drop of twenty degrees practically overnight. There was a brief moment, just a few days as September became October, where we had all the windows open from dawn till dusk to let fresh warm air sweep through the house. Time to shut them again, layer up with a sweater, and turn on the heat at night.
