Arizona weather forecast: Roller-coaster ride of temps in Phoenix
Morning Weather Forecast - 4/7/26
Valley weather will be a roller-coaster ride this week, with highs in the 90s on Tuesday, and highs dropping back into the 80s by the weekend.
PHOENIX - After a nice break from the warmth on Monday, we're back to the 90s for the rest of the work week!
Today:
The forecast high climbs back to 93 in Phoenix on Tuesday afternoon. A ridge of high pressure will quickly climb across the southwest this week. While not nearly as strong as the ridging of March, it will push highs into the middle 90s by Wednesday.
The storm system that brought wet weather to the state on Monday will continue to shift eastward today. Along the eastern edge of Arizona, a few showers or a spot thunderstorm may fire off on Tuesday afternoon. Some clouds will build over the higher elevations by the afternoon, as well. Most of the state, however, will remain sunny.
The Rest of the Week:
Wednesday is forecast to reach 96 and Thursday will remain around 95. Both days are sunny in the Valley. By Friday, the forecast turns cloudier. The high temperature starts to slip, dropping to 90 in the afternoon. This change is due to an approaching low pressure system that will move over the Pacific, along the West Coast, and eventually cross California into Arizona. This low will bring an increased chance for scattered showers and thunderstorms. Winds will increase and temperatures will drop over the weekend, too.
This Weekend:
The forecast high is currently 86 on Saturday and 80 on Sunday. The chance for rain shifts from 20% in Phoenix on Saturday, 40% Saturday night into early Sunday morning, and 20% during the day Sunday. Rain chances are stronger in northern Arizona over the weekend.
