Arizona weather forecast: Milder conditions coming to the state
Morning Weather Forecast - 5/15/26
Happy Friday! Highs are dropping back into the 90s over the next several days in the Valley.
PHOENIX - Good news for the weekend! Our forecast includes a cool down and sunshine.
What to Expect:
The forecast high remains near 100 degrees for the next two days, as we sit between two ridges of warm air. One ridge sits well to our east, the other to our west over the Pacific.
The warm air that lingers over our state will eventually be bumped as more mild conditions settle into the region. This more mild period is the result of an upper-level storm system that will slide down the west, and stop just north of Arizona. As it approaches, it pushes cooler air southward and also increases the winds around the west and Southwest.
The forecast high drops to 94 by Sunday. Weekend winds are forecast to pick up with gusts of 30-45 mph in the High Country and 15-25 mph in the Valley and surrounding lower desert locations.
Looking Ahead:
Early next week, as the system slowly passes to our north, we'll continue to feel the effects on our temperatures. The forecast high drops to 92 in Phoenix on Monday and remains at 94 on Tuesday.
By Wednesday, ridging will return as the low exits to our Northeast. This means the forecast high will start to jump back up. Low triple digits are expected by mid-late next week.
The pattern still looks generally dry over the next week, with sunny to partly sunny sky conditions around Arizona.
