MOST ACCURATE FORECAST: Cooler and drier air moving in

Cooler and drier air moving in - for now
Posted
and last updated

PHOENIX — Showers and thunderstorms will continue across northern Arizona today as an upper-level low moves through the Four Corners.

Here in the Valley, our forecast is drying out as cooler air settles in.

Temperatures will dip into the low to mid 80s Thursday and Friday, bringing a nice cooldown to wrap up the week.

By the weekend, high pressure returns and our temperatures will climb again, with highs back in the low 90s before Halloween.

On average, Phoenix sees its last 90-degree day around October 30, but we’ve had 90s stretch as late as mid-November, so it’s still possible we’re not done just yet.

2025 Sky Harbor Official Rainfall to date: 7.49" (+1.72" from average)

Monsoon 2025 Sky Harbor Official Rainfall: 2.76" (+0.33" from average)
