Morning Weather Forecast - 6/29/26

Highs in the Valley will be below normal on Monday at around 103 degrees.

Windy conditions persist around the state today as temperatures remain below normal.

What to Expect This Week:

An area of low pressure continues to whirl to the north of Arizona with an associated trough driving mild air across our region. This pattern brings dry air and windy conditions to the state, as it keeps the temperatures down. While we will not see any chance of showers, we will continue to see gusty winds. Gusts of 15–25 mph are forecast in Phoenix and 30–40 mph in Flagstaff.

Unfortunately, gusts will remain in the 30–40 mph range around the Pocket Fire again today. The south/southwest wind flow will push smoke, at times dense, over Flagstaff and the surrounding area.

Winds will remain around the same intensity on Tuesday before gradually weakening between Wednesday and Thursday. As a result, there is another red flag warning over northeastern Arizona on Monday, and a fire weather watch for the same area on Tuesday.

Temperatures sit below normal today. The forecast high is 103 in Phoenix with a low of 77 degrees tonight. The comfortable temperatures stick around Tuesday and Wednesday with highs at 102 and 103, respectively. It will remain sunny and dry.

This Weekend:

Starting Thursday, the highs will slowly climb. We're expecting a high of 104 on Thursday and 106 on Friday in the Valley. By the weekend, Independence Day will reach 107 and Sunday hits 110. Sky conditions shift to a partly sunny sky between Thursday and Sunday.

Looking Further Ahead:

Next week, the forecast highs start to quickly rebound, with 110 and hotter expected between Sunday and at least mid-next week.
