Morning Weather Forecast - 5/12/26
An Extreme Heat Warning will be in effect for most of Tuesday in the Valley.
PHOENIX - Another day of high heat around the Valley and state.
Today:
The forecast highs remains well above average on Tuesday. Phoenix is forecast to hit an afternoon high of 106. The current record is 109 and the average high is around 93 degrees. It will be a mostly sunny day, but a few passing clouds are expected.
Dig deeper:
The dome of high pressure pushing temperatures well above normal is beginning to shift eastward. As this happens, a small amount of moisture is wrapping up and around the high in a clockwise motion. This is allowing just another moisture for scattered clouds and a low chance for a sprinkle to sneak into Arizona's forecast. Today, the low sprinkle chance remains over southern and eastern Arizona.
The Rest of the Week:
On Wednesday, there is an additional chance for an isolated shower or sprinkles over the higher elevations of northern Arizona. The forecast high drops to 101 in Phoenix by Wednesday with a partly sunny sky. By Thursday the high drops again, down to 99 degrees.
This Weekend:
Temperatures will remain near 100 degrees through the weekend and early next week, too.
Big picture view:
Rain chances will be hard to come by over the extended forecast. Instead, a typical warm pattern will grip the state into next week.
