Not Much

Light showers over the Catalinas early yesterday afternoon. These showers produced rainfall, very slight amounts, at 4 of the 93 ALERT stations in Pima County and that was that.

Slow dry out at low elevations continues with PW values down around an inch. Soundings indicate no CAPE at low elevations. At 500 mb a weak cutoff is embedded within the larger western US anticyclone, and is over New Mexico and northeastern Arizona. This is bringing northerly flow and cooler middle-level temperatures across the eastern half of state. With warm surface temperatures this afternoon, we can expect some more high-based Cbs over the mountains and dry, gusty winds at low elevations. Some cirrus streaming in from the Pacific, but not much of great interest on the horizon.

September continues much like August. There has been measurable rain here at the house on only 5 days since July 22nd.
