That view is looking south into the teeth of the haboob . . or "big dust storm". The mountain range that marks the southern border of Phoenix has disappeared.
The sky becomes an ugly sort of brown as the visibility drops. But then, after these long dry months, comes the refreshing rain accompanied by some lightning, quite a bit of wind and wonderful thunder.
Today is forecast to be clear, sunny and hot again but the possibility of more rain exists from Wednesday though the end of the week. We can use it but at least now I can stop bitching about the lack of it.
