The heat wave that hit the Valley this week will take a break just in time for the Arizona State University commencement ceremony Monday.
“As we transition into our summer, this might be our last ‘hurrah,’ ” said National Weather Service meteorologist Andrew Deemer.
A low-pressure system moving out of the north Pacific Ocean will push through Phoenix starting Sunday. Temperatures will fall to the mid-70s and stay there until about Wednesday, according to the National Weather Service.
There will be some wind and could be some rain. Wind gusts will be as high as 50 mph and there is a small chance of rain Tuesday, Deemer said.
Arizona has been under a ridge of high pressure pretty common for this time of year. Phoenix beat a record temperature Friday when it hit a high of 108 degrees. The record was 105 degrees in 1989.
The coming 40-degree drop is not unheard of for this time of year, but it doesn’t happen often, Deemer said.
According to Deemer, heat has been arriving in the Phoenix area earlier in recent years. The typical 100-degree day has historically been May 2.
“We’re not too far off that,” Deemer said.
There could also be some improvement by Graduation Day in the gray, hazy air that sat over the Phoenix area Saturday. But it’s expected to get worse before it gets better.
According to the Arizona Department of Environmental Quality’s website, the ozone level on Saturday was 74. It’s expected to increase to 80 on Sunday, but on Monday and Tuesday Phoenix will see a moderate drop to 67.
It will remain at the moderate level. Unusually sensitive people should not spend much time outside.
