A quick look at this morning's charts by someone who defintely feels snakebit!-----------------------------------------------
The Tucson morning sounding (top) has perhaps a bit of CAPE and moisture values are up some across all of southern Arizona. Yuma has experienced at least a shallow surge of mT air since 4 am with the dewpoint rising 28F! The wind profile is actually pretty good, except for the continuing southeasterly winds in low-levels. Temperatures are quite cool in middle-levels.
----------------------------------------------
The 500 mb analysis from RAP (bottom) shows the large and amorphous high continuing over the Southwest and Mexico. There appear to be two lobes in the anticyclone this morning - one off toward the Four Corners and the other over southern California. There is a distinct, but weak, inverted trough across across northern Mexico and into southern Arizona.

After yesterday, I'd be hesitant to rule out isolated storms again this afternoon, given a number of favorable aspects noted above. I will certainly be interested in whether or not the variant WRF model runs indicate any chance of storms!
