Summer rains in the High Desert come up on humid afternoons when the heat is very high. Last week we had three days of it. Mornings are relatively cool, but the clouds becoming towering in the afternoon. Suddenly, they drop rain in very precise locations. Last year, when I was driving back from Phelan, I saw torrential rain on one side of the intersection of Pearblossom Highway & Largo Vista Road. The other side of the intersection was totally dry! Tuesday the rain came down pretty hard...but only for about 5 minutes, so we got only .02 of an inch.
