Strange ride to work. Last week, heck even yesterday, it was cold. That is, cold for L.A. Upper 30s, lower 40s f. This morning, a Santa Ana wind was developing (blowing down from the north/north east). It's a dry warm air mass because the air is friction heated by going up and over the mountains, and from the air molecules rubbing against each other. By the house, it was in the upper 40s, but when I reached a major intersection, the temperature shot up, like I was standing next to an open oven set to 300f. Crossing the street, the temp dipped again. It kept doing this all the way to work. Wild swings in temperature block by block. And the winds got stronger as I crossed across the valley floor.
Must have been 75 degrees on the way home, with a great tailwind.
