Mostly a suppressed day, with some light storms on mountains. Dewpoints were running 30s to 40s over almost all of south-central and southeastern Arizona at 5 pm this afternoon. There were a few lightning strikes as close as off to the northeast of the Catalina at midafternoon. Safford had a heavy rainshower, gusts to 45 mph and a cool moist outflow a bit after 4 pm. This evening, right around Tucson, we're seeing mostly cumulus pancakeus, which fits the sounding shown above for 00 UTC - a tiny bit of CAPE right around 500 mb. Sounding is too dry by a bit more than 6 mm (compared to GPS PW) and the boundary layer probably has a well-mixed mixing ratio of about 4.5 g/kg. We'll see what morning brings!
