Arizona weather forecast: Cloudy, milder than normal conditions expected across the state
Morning Weather Forecast - 5/19/26
Our below-average highs continue as the Valley will top out near 91 degrees on Tuesday.
PHOENIX - After a lovely Monday, the forecast continues to bring pleasant conditions to the region.
Today:
The Valley capped at 87 degrees on Monday, and will warm just slightly more on Tuesday. The forecast high is around 91 degrees in Phoenix on Tuesday afternoon. Temperatures around the state will yet again sit fairly mild compared to normal. There will also be passing clouds around the state Tuesday into Wednesday, especially in southern and eastern Arizona.
The Rest of the Week:
The more mild temperatures are the result of another disturbance passing to the north today through Wednesday. This system will be followed by another, which will pass to our south, around Friday. This pattern continues to slow our warming, which allows for temperatures to remain fairly nice for this time of year.
The forecast high hits 94 on Wednesday and 96 on Thursday in the Valley. Each day will be sunny to mostly sunny. Over the next several days, some light to breezy winds are forecast for the state. Stronger winds will be possible in far eastern Arizona.
By the weekend, the forecast high returns to the upper 90s and low 100s. It will reach 97 Friday, 98 Saturday, and 100 Sunday.
Looking Further Ahead:
A possible additional system may make its way to Arizona by early next week. While too early for a high level of certainty, this could bring low shower/storm chances and moderated temperatures, again.
