The Antelope Valley is high Mojave Desert. Since it is a desert, it can be easy to have the cold weather and the precipitation happen on different days. This year they happened the same day, Thanksgiving!
Ever been to the California Poppy Preserve in spring when the wildflowers are going full tilt? This is what the Poppy Preserve looked like yesterday afternoon, under about four inches of fresh snow!
And of course, when it snows, play with snow!
Drive carefully and enjoy the rare (at least for low-altitude parts of California) White Thanksgiving!
