Rain chances and cooler air

PHOENIX — A storm system is moving in and bringing wind, rain and cooler air to Arizona.

Here in the Valley, there is a slight chance of light rain showers tonight and a chance for more light to moderate showers on Tuesday morning.

Up north, a few sprinkles are possible tonight. Then, scattered showers and thunderstorms will fire up along the Mogollon Rim and into northeastern Arizona on Tuesday afternoon.

Breezes are picking up, too. Gusts here in the Valley could hit 20 to 25 mph.

With winds mainly out of the west-southwest, smoke from the Hazen Fire burning near Buckeye will continue to impact the West Valley and parts of Phoenix.

This storm is also bringing a lot of cooler air with it, dropping temperatures nearly 20 degrees in parts of our state.

Phoenix hit 98 degrees on Sunday and has so far only made it to 80 on Monday afternoon.

We’ll fall into the 60s overnight before climbing back up to 80 degrees on Tuesday afternoon.

High pressure will start to build in behind this storm, sending temperatures soaring into the 90s by Thursday and into the triple digits over Mother’s Day weekend.

2026 Sky Harbor Official Rainfall to date: 0.32″ (-2.48″ from average)
