Few Showers Around


Some cloud color over the Catalinas before sunrise this morning.


There was very limited thunderstorm activity over Pima County yesterday - plot above shows detected CG flashes for 24-hours ending at 12 UTC this morning. The airport did report thunder during the mid-afternoon, as well as 0.04" of rain. Nothing here.

The Alert network sites (below for north and south portions) indicated scattered, mostly light amounts over the mountains and southern portion.




Yet another morning sounding with limited moisture below 700 mb (above), some CAPE, and mostly light and variable winds aloft. We really need a feature that will move some low-level moisture up the GoC - as per: an MCS into the middle GoC, a TS near the south end of Baja, or an inverted trough (IT) moving west across northern Mexico.

The forecast for precipitation through midnight tonight (below, from 12 UTC WRF-RR) looks very dismal.
