PHOENIX — Our Extreme Heat Warning for the Valley has been extended through Wednesday and it will likely get extended again.
Temperatures are set to climb above 110 degrees every day this week with little overnight relief.
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.

While heat remains the big story, there's still some moisture around for monsoon storms.
The Valley could see some showers on Tuesday morning, with our next chance for spotty storms back in the forecast on Friday.
2026 Sky Harbor Rainfall to-date: 0.76" (-2.95" from average)
2026 Monsoon Rainfall to-date: 0.44" (-0.35" from average)
