Based on my amateur meteoroligist ;o) interpretation of the animation the CMC appears to be forecasting that dry air from a broad flow running west-east across Baja and Mexico will expand northward into Arizona. If you look at the 16-km Water Vapor animation at RAMSDIS (http://www.cira.colostate.edu/ramm/rmsdsol/main.html ), you'll see the dry air flow I'm referring to. It's already starting to make some headway into our neck of the woods er, desert. By Friday morning, I'm guessin' we'll see a pretty clear indication of whether or not that Pacific system will be pushed north and around Arizona by that dry air flow.
