A watch is not expected given the localized/sporadic nature of the severe risk. DISCUSSION...Isolated thunderstorms are developing along the Mogollon Rim and far south-central AZ this afternoon, where temperatures have warmed into the 105-110 F range amid upper 50s dewpoints. The resulting deep boundary layer/steep low-level lapse rates -- characterized by an inverted-V thermodynamic profile -- will support dry microburts with severe-outflow potential with any stronger updrafts that develop. Weak deep-layer shear should generally limit updraft longevity/organization, and the overall coverage of severe storms is expected to remain too minimal for a watch. ...Weinman/Bunting.. 07/17/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!7qW1dq0f9gqCmUCvYzw6s9ShTT2hwEPwlXjPLl9FC2SoBy2JJGrnZhf_DZ8UA57EPUq9HjC_1= ikr_qz64vH_4ImUuB8$ for graphic product...
