Arizona Weather Forecast: Above-average temperatures to persist
Morning Weather Forecast - 3/23/26
We're still expecting a rather hot week, but a cooldown is on the way.
PHOENIX - While temperatures won't be as brutal as last week, they'll still run well above average and pass records through this week.
What To Expect:
So far, there have been 5 records in a row, including reaching 105 degrees on Thursday, Friday, and Saturday. There are an additional 6 days ahead where we'll likely break records. This will complete an 11-day stretch of consecutive records set.
The ridge of high pressure that pushed us to 105 last week has since weakened to the south. However, a new ridge is building to the west and will slide over the southwest throughout the work week. As a result, the afternoon high temperatures will actually run slightly lower today compared to the days to follow. A few high clouds may pass the state between these two ridges, as well.
Temperatures:
The high reaches around 99 degrees in Phoenix on Monday. It will be mostly sunny and dry.
By Tuesday, the high returns to 100 degrees and reaches 101 degrees by Wednesday. Thursday and Friday are forecast to hit 102 degrees, the pinnacle of this round of warming.
Looking Ahead:
Starting this weekend, a slightly more mild push of air will approach from the West. This will help bring down our temperatures gradually. Highs slip back into the 90s over the weekend and 80s are possible by next week. In addition, some moisture may be able to enter the state, and there's at least a limited chance for showers between Sunday and Monday of next week.
