Above is 8 pm MST regional radar (from NCAR RAL) showing heaviest storms already west of Tucson, out in central Pima County. Phoenix had a nice, widespread storm and rain event, not as severe as the forecast by early WRF-GFS. The Phoenix Rain Index for 24-hours ending at 07 UTC this morning is below. Heaviest amounts up there occurred a bit south of the metro area - the 12 UTC WRF-GFS forecast shifted the heaviest storms south into Pinal County. I would say that the models had a pretty good lock on the events of yesterday.
Here in the Tucson area coverage of rainfall was considerably up, as forecast by the early WRF (from 20% on Monday to 60% across the ALERT network yesterday). Heaviest amounts were again at higher elevations. A heavy storm moved by just to the southwest of here, leaving us with only 0.09" at the house. Two sites in the Catalinas had over an inch, as did Haystack Mountain, off to the south-southwest of Tucson. There were 12 sites with over half an inch. Below is a plot of stream flow at the USGS Rillito at Dodge gauge, showing a peak flow of 800 cfs during the night. This was the second morning this week that there was water running in the Rillito during my morning walk.
