Nice color with some build-ups looking toward the Rincons at 6:45 am MST this morning.
Thunderstorms were widespread across central Arizona during the 24-hours ending at 7:03 am this morning (plot of detected CG flashes above from Atmo and Vaisala). There were eight reports of severe winds and hail in the Phoenix area yesterday afternoon.
Across the metro Tucson area the coverage of measurable rainfall was nearly 100% - above graphic shows rainfall reports from Mesowest for rain amounts ending at 7:30 am this morning. Here at the house we had only 0.02"; airport had a Trace; DM reported 0,15"; and Atmo had 0.08".
The morning TWC/TUS sounding (above) is a bit weird, but there is some lingering CAPE (not nearly so much as SPC analysis indicates). The 500 mb analysis (below) shows the cyclone centered out west of Tucson.
As the 500 low moves across southern Arizona today there will be a chance for some light showers; however, the WRF forecast runs at Atmo forecast that most rain/showers today will remain well northeast of our area. Graphic below shows 12 UTC WRF-RR forecast of precipitation amounts through midnight tonight.
