The National Weather Service issued an extreme heat warning for the week in metro Phoenix.
Meteorologist Sean Benedict predicted higher temperatures.
“So there’s a very high probability that it will be upgraded to a warning, especially for the Wednesday-Thursday timeframe when we see our highest temperatures, any time we're expecting temperatures to get near the record monthly temperature," he said.
Benedict says the later forecast includes a possibility of rain coming up.
"This high pressure setup, it’s a little bit more favorable for our typical monsoon setup so we do anticipate the moisture to try to start creeping up. And you will probably start to see some storms in the distance in the higher terrain," he said.
Temperatures are expected to climb to record territory Wednesday and Thursday in Phoenix. And an extreme heat warning remains in effect through Friday. National Weather Service meteorologist Ryan Worley says a massive heat dome sitting over the Southwest is to blame.
"Its position right now is really promoting these above-normal temperatures and really limiting any moisture that could keep us a little bit cooler," said Worley.
Worley says the heat dome covers most of the state. He expects temperatures in metro Phoenix will start to drop slightly this weekend, though they’ll still be in the 110 range.

2025 was the second-hottest year on record in Phoenix. And climate change made a number of other impacts on Arizona throughout last year. -
Arizona officials will begin reviewing recommendations to keep workers in the state safer in extreme heat after a task force submitted findings to the agency. -
We all know that Arizona is hot. Too hot, oftentimes, for workers to safely spend long periods working outdoors — or even indoors where there’s not good air conditioning or air flow. -
The calendar says it’s winter, but the weather says it’s spring. Even by Phoenix standards. -
Arizona has never had statewide regulations to protect workers from extreme heat. Neighboring California does have a workplace heat safety standard. A new study says California's policy saves lives.
