View of Catalinas above from 05:00 pm MST yesterday, just before storms moved into central metro area.
Visible satellite image from 06:30 am this morning (below) shows widespread, heavy cloud cover over much of the Southwest. How long will it persist later today?
Plot of detected CG flashes (above, for 24-hours ending at 02:00 am this morning - from Atmo and Vaisala) indicates considerable thunderstorm activity from Santa Cruz County north across eastern Pima and into Pinal County, yesterday afternoon and evening
ALERT map of rain reports (below, for 24-hours ending at 07:00 am this morning) shows essentially 100% areal coverage of thunderstorm rains across northeast half of network. Other amounts: Atmo 0.31"; TUS 0.23"; here 0.20; and DM 0.14". Heaviest rains stayed mostly over the mountains north and east.
At 500 mb this morning (12 UTC large-scale analysis above) indicates inverted trough persisting from central GoC into western New Mexico. A piece of this trough, or a large MCV, moved northward across the Tucson metro area early this morning.
Below is the 12 UTC TWC sounding plot (ignore CAPE analyses which over-play CAPE) shows a typical onion-shaped sounding that follows storms and rain, with dry low-levels below 600 mb. There will likely be small CAPE this afternoon, if we get some sunshine and heating, plus lift through the inversion above BL - which are the big question marks for today. Maximum temperatures will also possibly be damped by the clouds and yesterday's rains. The usual scenario for this type situation brings a down-day for today.
