Nothing On Horizon

Few clouds drifting over the Catalinas this morning, as our summer of discontent continues.

Another extremely suppressed day yesterday, with only a couple of isolated thunderstorms far to our southeast (detected CG flashes from Atmo and Vaisala above for 24-hours ending at 1:00 am MST this morning).

The morning sounding from TWC (above) is marked by deep westerly winds and just a sliver of CAPE. The PW continues right around an inch. We remain under the influence of the western U.S. trough at 500 mb (12 UTC analysis below from SPC), while the main anticyclone is way off over central Texas. All of this is just beyond printable words.

Very little change forecast through the coming week, as the 500 anticyclone shifts toward northeastern New Mexico (forecast above from 06 UTC GFS, valid at noon on Friday the 14th). Total precipitation forecast (below from same run) through the same period below, keeps Arizona almost rain free.
