A Sunday Summer Storm; August in Arizona


Desert Weather is very unpredictable.  We were given two days of 70% chance of rain, and possibly heavy rain at that.  My total? 0.14″.  However, nearby, often following predictable geographic steering, heavy rains could be seen just miles away.  It is often as if the storms tend to follow the valleys after being triggered by mountains or other means of convergence. Once I was working at a home a few miles away, well about 8.  Every day there were heavy rains, the ground was saturated.  I’d call home; Is it raining there?  No.  By the time I was home up the hills; bone dry.  On some occasions, the opposite happens, where the hills have the buildup “locked” in overhead.  Then we can get big rains 1-2″ from quite a small rain shaft. (This stalled storm effect happened about 2 hours after this post was written–approx 1″ of rain in 20 min.  Largest hail dime size.)
