Arizona weather forecast: Warm-up continues with triple-digit highs in Phoenix
Morning Weather Forecast - 6/2/26
The Valley's warm-up continues on Tuesday, with highs in the mid-100s.
PHOENIX - Our warm-up continues this week. A ridge of high pressure sits to our east, over Texas, for the next couple of days.
At the same time, an area of low pressure will take shape and run to the south of Arizona between Wednesday and Thursday. This combo helps guide humid, warm air across the south and Southwest, including in eastern Arizona. This brings the eastern edge of our state low shower and storm chances for the next few days.
Today:
On Tuesday afternoon, the forecast high reaches 105 degrees in Phoenix. It will be a mostly sunny day with light to low-end breezy conditions. In eastern Arizona, the chance for showers only hits 10-20% Tuesday afternoon. There is also the threat of dry lightning, which increases the fire risk for the area.
The Rest of the Week:
A bit more moisture will uptick our rain chances by Wednesday afternoon for the same general area of eastern Arizona, over the White Mountains and up the eastern portion of the Mogollon Rim. Temperatures continue to rise, with a forecast high of 106 Wednesday and 107 by Thursday in Phoenix.
Rain chances will yet again sit scattered on Thursday afternoon for the eastern part of our state. Yet again, a few storms could fire off over the higher terrain. Rain chances cut off by the weekend as the storm system to our south pulls away from us. Our temperatures remain warm, but will slip back to 106 Friday, 104 Saturday and 103 Sunday. It will be sunny to mostly sunny each day, too.
Looking Further Ahead:
Next week the triple digits stick around, but do not climb much – remaining near 105, again.
