Arizona weather forecast: Another day of record-breaking heat expected
Morning Weather Forecast - 3/20/26
Buckle up! Our stretch of triple-digit temperatures will last for some time yet.
PHOENIX - After shattering records around the state and region on Wednesday and Thursday, we'll do it again today.
What To Expect:
The strong ridge of high pressure atop the Southwest will continue to bump temperatures up all around the region. With the center of the high focused atop Arizona, we'll see our hottest temperatures of this heat wave through Saturday.
Today:
Today we'll reach an afternoon high of 106 in Phoenix. In Flagstaff, the high will yet again climb into the low-mid 80s-- which is around their July average high. It will remain sunny and dry, with low-end breezy conditions. Yet again today, record highs will fall across the state. In Phoenix, the current record high is 96 degrees, set in 2017.
This Weekend:
Saturday afternoon will climb to 105, and Sunday reaches 101. Both days will yet again set records for warmth in Phoenix.
The anomalously strong high pressure dome will weaken and slip to the southeast by Sunday. However, it's replaced quickly next week with a new ridge. This will continue to keep the Valley around 100 degrees through next week, with additional records falling daily.
Looking Further Ahead:
The forecast currently remains around 100 Monday and Tuesday, and 101 Wednesday and Thursday. Morning lows will stick in the upper 60s to low 70s.
For now, there's still no relief in sight as sunshine and heat prevail for the next 10 days.
