Discussion:
High pressure near the Four Corners region has ushered a more humid airmass into Arizona today, as evidenced by the cloud buildups and isolated showers this morning. Expect a chance of high-based showers and thunderstorms through this evening. Some cloud buildups are possible again tomorrow, but the chance of thunderstorms will diminish as high pressure builds again to our west and north winds dry us out again. The thunderstorms today will be capable of gusty winds, locally heavy rain, and small hail. Storm motion will be generally towards the north at about 10 mph.
High pressure will build back over Arizona through Thursday for near record warmth once again, until another trough moves through the Great Basin and brings some breezes on Friday and slightly cooler temperatures for the weekend.
So far, this is the driest monsoon on record for Prescott according to the NWS (see attached weather image). We have two weeks to go until the official end of the monsoon season on Sept. 30.
Meanwhile, this is also turning out to be a record hurricane season (https://www.theverge.com/2020/9/18/21444296/tropical-storm-wilfred-2020-hurricane-season-greek-names).
