Published October 23, 2026 7:38 AM MST

Friday morning temperatures across Phoenix show most residents starting in the mid-to-upper 50s or low 60s. Wickenburg recorded upper 40s, while temperatures reached 59 degrees in Mesa, Phoenix-Mesa Gateway Airport, and Apache Junction.

Across the High Country, temperatures dipped lower, reaching 31 degrees at the Grand Canyon, 35 degrees in Flagstaff, 50 degrees in Sedona, 41 degrees in Prescott, 44 degrees in Kingman, and the upper 50s along the western border of Arizona.

What to Expect on Friday:

Satellite and radar loops indicate a calm morning compared to previous severe weather and expired tornado warnings. However, significant rainfall over the last 24 to 48 hours has created ongoing flooding risks along several creeks and rivers.

Oak Creek in the Sedona area is under a flood warning until 11 a.m. on Friday. A flood warning remains active until 3 a.m. on Saturday for the Little Colorado River stretching from Leupp through Winslow to Holbrook. Additionally, Cow Springs Wash and the Little Colorado River in northern Arizona remain under flood warnings until noon on Friday. Residents in low-lying areas should remain weather aware as swollen waterways overflow their banks.

This Weekend and Next Week:

Temperatures going into the weekend are expected to drop eight to nine degrees below seasonal averages. Friday high temperatures will reach the upper 70s to lower 80s in the low deserts, lower 60s in the Rim Country, mid-50s in Flagstaff, upper 50s at the Grand Canyon, and upper 70s to lower 80s along the western border.

Clear, sunny skies and upper 70s temperatures will continue through the weekend. Temperatures will gradually warm into the lower 80s on Monday, reaching the mid-to-upper 80s by the middle and end of next week.
