View of Catalinas at 06:00 am MST this morning showing both middle and high clouds.
Two weak outflows moved into southeastern Arizona during the early morning hours increasing low-level moisture so that PW values have inched up to around an inch.
Shown here are the 06 UTC WRF forecasts, from Atmo, of total precipitation through 11:00 am next Tuesday, the 22nd. The GFS version (above) remains mostly dry through the period, while the NAM version (below) is considerably wetter.
There is a weak inverted trough at 500 mb moving westward along the Borderlands today and perhaps increased storm activity that area will help increase chances for storms here in eastern Pima County.
