Morning Weather Forecast - 4/30/26

We're closing out the month of April warm! The high on Thursday in the Valley will be just over 90 degrees.

We'll end the month with a nice day around the state!

Today:

The forecast high for Thursday afternoon reaches 91 degrees in Phoenix. Around the Valley, a few passing clouds are likely later in the day. This is due to a storm system passing to our south throughout the late afternoon and night.

The rain associated with this system will fall short of the Valley. Instead, as it skirts Arizona through the night, it will bring scattered showers, potentially a stray thunderstorm, to parts of Pima, Santa Crus, and Cochise counties. A few showers may run up eastern Arizona, too. Any storms could produce gusty outflow winds that approach the southeast/east Valley.

This brings a low chance of patchy blowing dust tonight, as well. While not a guarantee, Pinal County and Gila County will have slightly better chances of a spot shower.

Friday and the Weekend:

The low departs quickly by Friday morning, but the backside rotation of the storm may help trigger an isolated shower or storm Friday afternoon over the High Country mountains and eastern Arizona. Still, the chance only sits between 10-20%. The Valley returns to full sunshine by Friday, when the forecast high remains in the low 90s around Phoenix.

By the weekend, a small ridge will build and push our forecast highs into the mid 90s to upper 90s. It will turn breezy to windy Sunday across Arizona.

Looking Ahead:

Next week, another approaching system will slide our forecast highs down to slightly below normal, in the 80s, in Phoenix.
