Overview
- High pressure keeps Phoenix in the 90s this week with temperatures running about 10 degrees above normal.
- A low-pressure system from the Pacific will change the pattern, with a second low reinforcing it as the setup moves inland.
- Rain probabilities focus on northern and eastern Arizona, while the Valley holds around a 10% chance of a passing shower.
- Temperatures will trend down into the 80s this weekend and toward the upper 70s by early next week, with Valley wind gusts near 25 mph.
- Phoenix Sky Harbor has logged 0.32 inches of rain so far in 2026, about 2.36 inches below average, which means brief showers would offer little relief from the ongoing dryness.
