Near-Record Heat Possible Sunday in Phoenix After Brief Cooldown

A rebuilding high-pressure ridge drives a quick rebound, with late-week rain prospects still uncertain.

Overview

  • Valley highs hold in the mid-80s through Saturday, with overnight lows in the mid-50s to low 60s.
  • Temperatures are forecast to reach about 88–89 degrees Sunday and remain in the upper 80s Monday, challenging Phoenix’s Nov. 9 daily record of 88 set in 2005.
  • The weekend stays sunny and dry statewide, with generally calm winds in the Valley and occasional breezes in northern Arizona.
  • Prescribed burns near Flagstaff and the Verde Valley may produce localized smoke, according to FOX 10 forecasters.
  • Forecasters expect a modest cooldown by midweek, while a possible Pacific storm late next week is still uncertain and could bring rain if it tracks into Arizona.
