PHOENIX — It's a sizzling week in the Valley!

Phoenix has been just a degree or two shy of 110 over the past few days, but now temperatures will soar even more over Father's Day weekend.

Extreme Heat Warning are in effect for central and southern Arizona on Saturday, Sunday and Monday with another Extreme Heat Warning in effect for the Grand Canyon for areas below 4,000 feet in elevation on Saturday and Sunday, including Phantom Ranch and Havasupai Gardens.

Daily highs in the Valley are expected to hit 110 to 114 degrees and come within a degree or two of the daily records on Sunday and Monday.

Our average first 110-degree day is June 11th, so it's just that time of year when temperatures really start to sizzle.

With dangerous heat setting, Saturday, Sunday and Monday will be ABC15 Weather Action Days. This is a reminder to take action to keep you and your family safe in the heat.

Make sure to stay hydrated, limit your time outside during the hottest parts of the day (usually between 11 a.m. and 6 p.m.), and wear lightweight, light-colored clothing.

If you have to be outside during the heat of the day, take frequent breaks in the shade or inside to cool off, and don't forget the sunscreen.

Temperatures will drop a few degrees by Tuesday, but we'll likely hit 110 or hotter again toward the end of next week.

Monsoon 2025 officially begins on Sunday, June 15th, but we are still waiting for high pressure to set up east of the Four Corners and allow moisture to move in. So for now, our forecast will stay dry.
