Arizona weather forecast: Cooler temps and possible wet weather expected
Morning Weather Forecast - 3/31/26
We're expecting temperatures to continue dropping, but a warmup is expected, starting this weekend.
PHOENIX - Our weather pattern begins to shift throughout the day.
What To Expect:
A trough and storm system begins to run inland from the Pacific today. This system will move north of Arizona, and drag more mild air into our region. At the same time, a quick-moving cold front will clip by our state and help to increase our winds and cloud coverage. A round of wet weather is expected to pass through our state as the front approaches, too.
Today:
We'll begin to see increased showers and storms over parts of Northern, Western and eventually, Eastern Arizona. A few storms could pack steadier rain, lightning, and gusty winds.
Into the night, the rain will start to fill out over northwestern Arizona.
The forecast high Tuesday reaches 92 degrees with mostly cloudy conditions. Gusts 25-40 mph are forecast in Phoenix and 35-45 mph in Flagstaff today.
As a result of the strong gusts, a wind advisory is in place for much of Northern Arizona until 8 p.m. tonight.
Tomorrow:
By early Wednesday morning, a few showers may slice by the Valley and even down toward Southern Arizona. Quickly those will pass to the east and by late morning-midday tomorrow, the state will dry out.
The forecast high drops to the middle 80s in the Valley.
As the showers move by, the best chance for some rain or a thunderstorm will be along the foothills against the north/east part of the Valley. In Phoenix, the best window for showers will be between 4 and 8 a.m. The chance is limited, 10-20%, in the Valley.
It will continue to be breezy in the Valley and windy in the high Country on Wednesday and even Thursday.
Looking Further Ahead:
Temperatures in the upper 80s will last through Thursday and Friday before low 90s return Easter weekend.
