We Come To Honor Dean, Not Bury Him

As former Hurricane Dean falls apart, it gets harder and harder to tell where its influence is.

Big thunderstorms are occurring near Nogales, AZ, and farther south right now. Those are influenced by Dean's moisture.

Dean will be in charge of AZ weather on the weekend, albeit in a hard-to-discern way, through the influence of moisture.

The center of circulation is heading NNW, up the west coast of Baja, oddly enough, with the 700 mb circulation finally surrendering on Monday off the coast of Monterey, CA. Nevertheless, AZ is downwind of the moisture plume at all times this weekend, so thunderstorms should be pretty active there.
