The heat has been extraordinary in the southwest, but Prescott is often in a more favorable weather pattern than their gigantic neighbors to the southeast. How does that translate this time around?

At 753PM, PT, Prescott was reporting a temperature of 80 degrees with clear skies. Some monsoonal rain showers were appearing on radar west of town, and a brisk west wind likely represented outflow, especially given the southeasterly winds of similar magnitude in Kingman. Guidance suggests a stronger ridge tomorrow over the central Rockies, which will stifle the monsoon and lead to a hot dry day in Prescott.
Expect some weakening of the ridge and an amplification of the monsoon. Afternoon and evening thunderstorms will be most common in the higher terrain nearer the New Mexico border, but the coverage is expected to increase on Tuesday. Showers and storms are likely to crop up near Prescott, and it’s tough to leave it out of the forecast for Tuesday.

I should note that it is 20 degrees cooler in Prescott than it was in Phoenix. Some of it is surely the thunderstorm nearby, seen on radar below.
