PHOENIX — Our Extreme Heat Warning remains in effect through Monday evening.
Temperatures are set to climb to nearly 115 degrees, with little overnight relief as lows only fall into the 90s.
So, our ABC15 Weather Action Days continue as a reminder to take action to stay safe in this dangerous heat. Limit your time outside and drink plenty of water throughout the day. Bring your pets inside too, and never leave kids or pets in the car.
Heat like this is becoming more common as our climate changes, and one of the biggest drivers here in the Valley is the rapid growth of our urban heat island.
Chief Meteorologist Amber Sullins spoke with researchers at ASU who have identified another reason why overnight temperatures in Phoenix keep getting hotter year after year. They have found that heat is being transported overnight from the west and northwest Valley into Phoenix.
Watch the full interview here:
With little monsoon moisture in place, our Valley forecast looks dry through the weekend. We could still see a few thunderstorms across the high country in the heat of the day.
Monsoon moisture will increase heading into next week as high pressure shifts farther east. That will bring a slight chance of storms back to the Valley starting Tuesday.
2026 Sky Harbor Rainfall to-date: 0.78" (-3.07" from average)
2026 Monsoon Rainfall to-date: 0.46" (-0.47" from average)
