Morning dewpoints across southern Arizona are again quite high, however precipitable water amounts are down below an inch everywhere except far southeast corner of state.
Only slight changes from yesterday when thunderstorms occurred only in far southeast.
For the fourth straight day there was no precipitation recorded at any of the gauges in eastern Pima County.
Anticyclone remains to the south but may be inching closer since winds at Tucson are quite light below 500 mb. This change in the shear may help mountain towers break through the very hostile dry air that is present above 700 mb. Sounding indicates little or no CAPE will be present at lower elevations by afternoon.
Weakening 500 mb S/W moves across northern Arizona today, with little impact down south except perhaps for some warming of the middle-level temperatures. Surge of very moist low-level air continues up the GoC and this may become important once the anticyclone moves back into the southwest US.

But for today the dry out continues.
