Widespread Rains During Night
Towers building west end of Catalinas at a bit after 7:00 pm MST yesterday (above) and a dreary Finger Rock view below, a bit before 7:00 am this morning (August 1st).
Widespread rain events last night - one before midnight and one after. IR image above is of the second event, while CG flash plot below is for 24-hours ending at 7:00 am this morning. Coverage was apparently 100% again, with many sites receiving over an inch of rainfall. The ALERT data remain unreliable due to problems of some kind. Here at house we received only 0.47" and I'm estimating that most of that (0.30") likely fell before midnight.
The Rillito was running bank-to-bank during the night - almost 3500 cfs a bit after midnight.
We continue under the influence of a slowly evolving, weak subtropical inverted trough that extends northeastward from central Baja just to our west. there are one or two embedded MCVs within the overall IT. The 06 UTC GEFS plumes below continue this wet pattern for the next three days or so.
Finally, these two week-long time series illustrate just what a stormy period it has been. The T/Td series from Atmo above shows 5 very distinct outflow events. The wind series below for TUS indicates 4 of these events produced gusts right around 50 mph (note that the frequent gusts to 38 mph are due to instrument or processing problems).
Both June and July had really active final weeks - separated by a long period of boredom.
