PHOENIX (3TV/CBS 5) -

The hottest temperatures of the year are in the forecast Monday through Wednesday as high pressure currently situated over New Mexico tracks westward into Arizona.

This set up will help suppress thunderstorm activity, limiting daily chances to the highest elevations.

Storms should be very isolated in nature.

An Excessive Heat Warning is in effect for the southern deserts, including Metro Phoenix Monday morning through Wednesday night at 8 p.m.

During this time, heat-related illnesses are likely for those who spend time outdoors without taking precautions like hydrating, taking frequent breaks in air conditioning an wearing light-colored, loose-fitting clothing.

In a tweet, the National Weather Service's Phoenix account warned residents to stay hydrated and take advantage of cooler indoor buildings.

"We can't stress enough that it will become dangerously hot early this week," the account tweeted.

By Thursday, steering flow begins to come out of the east.

This will allow some monsoon moisture back into the state and help drop temperatures. Storm chances return to the Valley by Friday.

On Monday, Phoenix broke the daily high-temperature record for July 23 with 115 degrees, beating the 2014 record of 114 degrees, according to the NWS.

Tuesday, Phoenix tied the record for daily high temperature for July 24 with 116 degrees.

In Phoenix, look for a high of 115 Wednesday.

Meanwhile, the Arizona Department of Environmental Quality extended an ozone high pollution advisory for the greater Phoenix area through Monday.

It means weather conditions combined with existing ozone levels are expected to result in local maximum eight-hour ozone concentrations that pose a health risk.

ADEQ officials say adverse health effects increase as air quality deteriorates.
