PHOENIX — Dry, sunny, and quiet weather pattern this next week as high pressure builds over the desert southwest and brings a big warm-up to the Valley this week.
Daytime highs will top out in the mid-90s through midweek before climbing into the triple digits by Friday.
Overnight lows will drop into the low to mid-70s across the Valley each night.
Our forecast will stay sunny and dry all week, but we are tracking a couple of weak storm systems over the weekend and early next week that may bring a few isolated showers to the high country.
Slight chance of spotty showers and isolated thunderstorms will be in the forecasts across northern Arizona on Saturday and next Monday.
As the 2025 monsoon season comes to an end on September 30th, Phoenix will wrap up with 2.76 inches of rain, putting us more than a quarter of an inch above the average of 2.43 inches. The last time we had an above-normal monsoon was in 2021.
