Clear skies over the Catalinas this morning, after heavy storms moved across the east parts of the metro last evening. Plot of detected CG flashes (from Atmo and Vaisala - below) is for 24 hours ending at 0743 UTC (12:43 am MST). Note the red and orange clusters over eastern edge of Pima County.
Radar from 7:39 pm shows the two storm cells which moved from north to south. ALERT reports (below) indicate locally heavy amounts - one site had nearly three inches of rain. The Rillito was running again this morning.
At 500 mb this morning the anticyclone is in a nasty position to our west, near Yuma. The ridge extends northward into western Canada, and there are several embedded, weak troughs. The morning sounding from TUS/TWC (below) is still moist with some CAPE, but with apparent subsidence below 250 mb putting a strong cap on things at 500 mb.
Forecast from the 06 UTC GEFS runs shows PW crashing during next 24 hours, but recovering fairly quickly - this is caused by a forecast disturbance approaching the south end of Baja by end of the week. The plumes for QPF at the airport rebound abruptly for the weekend, but with a huge spread of almost two inches. Meanwhile we'll have a bit of drying, but with temperatures rebounding into the 105 to 110 F range. Note that the NWS has an excessive heat warning issued for tomorrow.
