Even though the situation was marginal yesterday, the nasty capping inversion moved away and some storms developed at low elevations late in the day. View above at 5:52 pm MST shows Cbs and developing towers to the north. My photo below at 7:17 pm shows rain shaft to the north-northwest of here.
Radar at 8:04 pm and CG flash density for 12-hours ending at 7:00 am this morning both show the storm activity focused over Catalinas and northwest metro area.
The ALERT rainfall for 24-hours ending 7:00 am this morning (above) indicates 24 sites with measurable amounts (0.04" or greater). The airport had a 0.01" and DM had a Trace. Radar indicates that heaviest rainfall may have occurred in the data void north of downtown toward Limberlost, since heavy radar echoes were nearly stationary over that area. Here at the house we had several periods after 6:45 pm with gusty winds of 30 to 40 mph, a bright lightning show, and then a brief period of heavy rain just after dark - total here was 0.32".
Finally, the observed 00 UTC sounding from TWC is shown below - compare to the forecast sounding from the midnight WRF-NAM shown in previous post, which was quite accurate.
