Morning Weather Forecast - 5/22/26
Memorial Day weekend in the Valley will be toasty, with highs near triple digits Friday through Monday.
PHOENIX - We're expecting slow warming to bring us to the low triple digits by the end of the weekend.
Friday and the Weekend:
The forecast high climbs to 97 degrees on Friday afternoon, which is perfectly average for the end of May. The warmer temperatures are accompanied by a few passing clouds over northern Arizona, and sunshine in the Valley. Winds will remain light to low-end breezy in northern Arizona, too.
The forecast high warms to 98 on Saturday in Phoenix and reaches 100 on Sunday. Both days will remain sunny and dry in the Phoenix metro. In northern Arizona, an isolated sprinkle is possible Saturday as afternoon heating lifts clouds over the higher terrain.
The better chance for showers to develop starts on Sunday. A few spot showers are possible in northern and eastern Arizona on Sunday afternoon. By Monday, an area of low pressure will approach Arizona from the Southwest. As this occurs, additional lift will help trigger showers and thunderstorms.
Memorial Day and Beyond:
For now, the best chance for storm activity appears to be over northern and eastern parts of the state with just a 10% chance of showers reaching the eastern or northern edge of the Valley. The forecast high caps in the mid 60s in Flagstaff, but near 100 in Phoenix on Memorial Day.
Behind that system, temperatures will slump back to the 90s through next week and potentially the following weekend.
