Arizona Weather Update: Expect Warmer Temperatures This Week

Phoenix experienced a cooler, cloudier Monday with a high near 87°F. This followed near-record warmth Sunday and a record-warm morning low of 78°F Monday.

A disturbance crossing Arizona caused the brief cool down. It produced widespread rain in higher terrain, with the heaviest totals along the Mogollon Rim.

Short-term forecast

Rain will clear from west to east Monday night. Most of the state should see sunshine Tuesday morning.

Winds will be breezy in the Valley Monday evening and overnight. Conditions are expected to be calmer on Tuesday.

Isolated showers are possible Tuesday afternoon in far eastern Arizona. Areas to watch include Window Rock and St. Johns.

In this Arizona weather update residents should expect warmer temperatures this week as a ridge builds. Temperatures rebound above average on Tuesday.

Extended outlook

The ridge will keep daytime readings roughly ten degrees above normal through Friday. Skies will be mostly dry and mainly sunny during that stretch.

Storm systems are forecast to return this weekend. Scattered rain is likely across Arizona, including the Valley Saturday and Sunday.
