Morning Weather Forecast - 5/21/26
Our gradual warming trend continues on Thursday in the Valley as we'll see a high right around normal at 96 degrees.
PHOENIX - Slow warming the next few days will eventually push us back to triple digits, but it doesn't last for long!
Today through the Weekend:
While our temperatures are warming up, the progression remains slow. The forecast high hits 96 degrees today in Phoenix. The average high is also 96 degrees, making today a perfectly normal day. It will remain sunny and dry across the state.
By Friday, a disturbance will pass to the south of Arizona. This doesn't bring us rain, but does keep the warming at bay. The forecast high climbs to 97 on Friday. By Saturday, the high is expected to hit 98 degrees. Again, it will remain sunny and dry. A few clouds will pass over northern Arizona.
This weekend there will be a very isolated chance for a shower over the higher terrain, but the state remains mostly dry. The high finally returns to 100 degrees on Sunday in the Valley. While a few showers may fire off in the afternoon over the northern/eastern high terrain, it will still be sunny and dry in Phoenix.
Next Week:
By Monday, a system will approach from the Southwest. This system brings a low chance for scattered showers/thunderstorms in northern and eastern Arizona. It will be difficult for showers to drift down the mountainsides into the Valley, but not impossible. As a result, there will be a 10% chance of showers in Phoenix.
This will help to yet again moderate our temperatures. The forecast high hits 100 on Memorial Day, but drops to 97 the following Tuesday and mid to lower 90s are possible late next week.
