8/23/2012 8:00 AM 1.16 M M M M I filed a sig weather report yesterday at 10:25 am when the heavy rain ended. Reporting period started with low clouds, looking more like a winter frontal system; embedded showers over mountains north and east of Tucson (Santa Catalinas and Santa Ritas). Thunder and gusty winds began at 8:32 am with first rain event (9:10 am to 12:15 pm); heavy rain periods 9:27-9:45 am and 9:54-10:08 am for a combined 22 minutes of heavy rainfall; rainfall amount of 1.05 inches. Literally filled buckets with water from gutter near porch, including a large garbage container. Thunder again with evening rain (9:15-10:30 pm); additional 0.11 inches of precip. Don't know if there were additional showers while I slept, however. Low clouds still present this morning, again looking more like winter; clouds attempting to build into convective cells; very humid, everything wet and soaked but little local ponding.
