....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF
ARIZONA AND PORTIONS OF SURROUNDING STATES...

....SUMMARY...
Isolated strong to severe wind gusts remain possible across Arizona
and portions of surrounding states.

....Parts of the Southwest...
Several clusters of strong storms are ongoing this evening from
southeastern California and southern Nevada across Arizona.  The
storms are occurring within an environment largely featuring modest
instability, though greater CAPE (upwards of 2000 J/kg) is indicated
over ports of the California desert and adjacent Colorado River
Valley.

With moderate mid-level southerly flow across this area, on eastern
fringes of the upper low just off the California coast, a few
stronger/organized storms will remain possible locally this evening.
 Potential for strong/locally damaging winds will accompany the
strongest storms/bands of storms, with potential aided by the deep
surface-based mixed layer across this region.

...Goss.. 08/19/2023
