PHOENIX — Extreme heat is back in the Valley!
As high pressure intensifies over the Desert Southwest, temperatures are back above 110 degrees in the Valley.
Phoenix Sky Harbor topped out at 113 degrees today, putting us just one degree shy of the record set in 2022.
This extreme heat is increasing the risk of heat-related illnesses, so Excessive Heat Warnings are in effect until 8 p.m. Thursday. These heat alerts also extend into southern and southeastern Arizona, and into parts of northern and northwestern Arizona too.
With these heat alerts in effect, we are in ABC15 Weather Action mode as a reminder to take action to keep you and your family safe during this stretch of dangerously hot days.
Stay hydrated, limit your time outside between 10 a.m. and 6 p.m., wear light-colored, loose-fitting clothing, and watch for signs of heat-related illnesses like dizziness, changes in pulse and muscle cramps.
By Wednesday and Thursday, it will get so hot in the Valley that we will flirt with records!
Wednesday's forecast in Phoenix is now up to 113 degrees, which could tie the record set in 2022.
Thursday's forecast is 112 degrees, just shy of the record of 114 degrees set in 1936.
We are also tracking a storm system that could bring a few showers and thunderstorms to Arizona later this week.
The best chances will be in the higher terrain on Thursday and Friday, but there is a slight chance of isolated showers here in the Valley too on Thursday.
This storm system will also help to drop temperatures a few degrees as we end the week. But, as it clears out this weekend we're expected to top 110 degrees again in Phoenix on Saturday and Sunday.
Monsoon 2024 officially begins on Saturday, June 15th and the outlook this year has odds favoring another drier and hotter-than-normal season.
