Significant Dry-Out



View of the Catalinas at 7:30 am MST this morning.

Plot of detected CG flashes for 24 hours ending at 0833 UTC this morning (from Atmo and Vaisala) shows limited activity in much of the metro area. However, both airport and DM reported thunderstorms. Precipitation reports (below - from MesoWest) show mostly light amounts for 24 hours ending at 8:00 am this morning - except around southern fringes of area shown. Here at the house we had a very brief shower that produced only 0.03"; Atmo and DM reported 0.21"; and the airport had 0.33".



This morning's TWC/TUS sounding above) continues to show some CAPE, although drier air is intruding from several directions. Forecast below (from the 06 UTC WRF-GFS) shows precipitation amounts through 06 UTC on September 29th. So much of the rest of September is likely to be very quiet weatherwise.
