Cooler Temperatures and Rain Expected in Arizona
US · Published Sep 22, 2026
Arizona is set to experience a significant weather shift this week as temperatures drop and rain chances increase.
After a high of 102°F (39°C) in Phoenix on Monday, a low-pressure system moving inland from California will bring cooler conditions and scattered rain to the region.

Impact & Risks

The primary risks this week include isolated flash flooding in eastern Arizona, particularly in areas prone to heavy downpours such as the White Mountains and Four Corners region. Residents in these areas should remain vigilant and monitor local weather updates. In Phoenix, increased humidity and potential rain may cause minor disruptions, but no severe weather is currently expected. Travelers should exercise caution in areas prone to flooding and avoid driving through flooded roadways.
