Summary

  • Phoenix enters five First Alert Weather Days with an Extreme Heat Warning in effect through Monday, and Saturday’s high is forecast to reach 116°F after 115°F on Friday.
  • A high-pressure system is driving temperatures 5-10 degrees above normal, while dewpoints in the 60s will push “feels like” readings even higher across the Valley.
  • Popular Phoenix hiking trails will close from 8 a.m. to 5 p.m. during the warning because of the dangerous heat.
  • Monday’s high is expected to ease to 106°F, but humidity could keep apparent temperatures near 111-113°F as storm chances rise to about 30%.
  • Most rain and thunderstorm activity should stay in Arizona’s mountain areas, though outflow boundaries could still bring some clouds or storms into the Valley.
