Big Rain In Southern Arizona

I just sent this to Deborah, who lives in Ahwatukee, in the southern Phoenix metro area:

Hard to believe! 0.83 inches of rain at Ahwatukee in the last 24 hours! Really, for late May, among the driest months of the year, that is unprecedented! I was watching that big rain blow-up last night on the Internet, from Ajo streaming northeastwards into the Phoenix metro area, and it made me very happy!

Indeed, some places are recording records (from the NWS Tucson office):
