More Storms Late In Day Yesterday
View of Catalinas this morning (above) shows some buildups northeast of the mountains. There was a second round of thunderstorms over parts of the metro area late yesterday afternoon and evening - some reports of small hail with these storms. Here at house we received an additional 0.14" bringing event total to 0.21" (more than entire month of October produced).
The radar/gauge rainfall estimates below (from FCDMC) are for 24-hours ending at 7:00 am MST this morning - yellows just over an inch and greens over a quarter of an inch. The storms yesterday tended to stay at low elevations - note max areas up Avra Valley and I-10 toward Phoenix and the heavy swath up the San Pedro River north of Benson.
ALERT amounts for the entire event (above) and weather.graphics CG flash density(below) for entire event, which was quite active for November.
The morning sounding from TWC on campus (skewT plot below from SPC) continues to exhibit considerable CAPE, due to the cold temperatures up to about 400 mb (observed -17 C at 500 mb). No 06 UTC WRF forecasts from Atmo, but earlier forecasts and this morning's NWS NAM indicate rapid warming in midlevels as the 500 mb low currently to our west moves northeastward. Showers and storms may linger briefly this morning but main activity shifts to our north and east.
