Rain! We had a light drizzle for a few minutes this morning. It was such a miracle that I went out and stood in it, to feel its delicious drops against my own skin and know that it was real!
Right now it's 2:30 P.M. and 69F, 8% humidity - didn't even make it to 70 today. Tonight we have a frost warning (!). Such a sudden and dramatic change is pretty typical. That is life in the desert: you burn one day and freeze the next.
