Arizona weather forecast: Wildfire smoke causes hazy skies
Evening weather forecast - 8/10/25
An extreme heat warning continues through Tuesday for the Valley and Thursday for the high country.
PHOENIX - It is a cloudy and hazy Sunday evening in the Valley. Wildfire smoke from California has been trapped under clouds, leading to low visibility and unhealthy air quality. Skies are expected to stay hazy/smokey for the next few days, thanks to a shift in the upper-level wind pattern.
Hazy skies in Arizona due to California wildfires
The air quality is taking a bad turn in the Valley and those hazy skies aren't from fires in Arizona.

Showers and thunderstorms are making their way southeast across the mountain terrain, and rain will come to an end overnight. We may see a light shower in the northeast Valley this evening, and there is a possibility for a morning shower in the Valley Monday. Temperatures will fall into the upper 80s overnight.
The week ahead:
Monday will be a hot day, with highs around 110 in the Valley. Extreme heat warnings are in effect for the Valley until 8 PM Tuesday, since temperatures will stay around 110 degrees for most of the week. Skies will be mostly sunny, but hazy. Isolated showers and thunderstorms will be possible during the afternoon in Rim country and the White Mountains.
The Valley will see a better chance of rain by Thursday, Friday and Saturday.
