The National Weather Service has issued a Flash Flood Watch for northern Arizona again today, but this watch does not include the Prescott area. Nevertheless, the atmosphere remains weakly unstable and extremely moist. Showers and thunderstorms will be likely again today, especially as a large band of showers pushes north into Yavapai County from southern Arizona this afternoon as evident in radar imagery (http://www.atmos.washington.edu/weather/radar_az.php). In advance of this approaching band of showers, thunderstorms have been triggering to the west of Prescott, but additional cells could trigger in the Prescott area as well.
Starting tomorrow, low pressure off the California coast will usher some southwest winds across northern Arizona, which will cause drier and more stable air to flow across the state. Expect a diminished probability of thunderstorms Tues. – Thurs., but nevertheless, there will still be a slight chance of thunderstorms each day. Starting Friday and through the weekend, we will return to a moderate monsoon pattern, with a chance of showers and thunderstorms each afternoon – evening (though probably not as active as it has been these past couple of weeks).
