The storms last evening, and during the night, stayed mostly to the north and avoided almost all of the Tucson Metro area. The morning forecast from the WRF-NAM was quite good, even though I thought it had under-played the convection. Above is photo from the house looking north about 6 pm MST - considerable area of updraft apparent but storms held off on this side of the mountains. This morning at 5 am only 16 ALERT stations reported rainfall during past 24-hours (17% as compared to 60% coverage last Saturday night). The Catlinas sector of the ALERT network (below) has all but 2 of the mostly light rainfall reports. The plot of CGs through 5 am this morning (bottom) shows that most of rain was associated with a thunderstorm that moved north-northeastward away from the Catalinas. Looks like the main weather activity during the coming week will remain well north of Arizona.
