The extreme heat wears on with our Excessive Heat Warning still in effect until 8 p.m. Thursday.

We broke a record yesterday at Phoenix Sky Harbor topping out at 113 degrees, two degrees above the old record of 111 set in 1999.


The record breaking heat will continue all week long! Here's a breakdown of what we expect:

Tuesday - Low 90 (Record 90), High 115 (Record 112)

Wednesday - Low 90 (Record 90), High 116 (Record 115)

Thursday - Low 91 (Record 89), High 112 (Record 112)

Friday - Low 89 (Record 87), High 110 (Record 114)

So, we are going to be adding to our tally of 110+ degree days which is already at 23 this year. On average, we see 18 110+ degree days a year. The record is 32 days at 110+ set back in 2007.

Heat this intense puts extra stress on a person's body and can lead to heat-related illness or even death. Make sure you check on elderly neighbors and protect infants from the extreme heat too; these groups are the most vulnerable to heat related illness.

The Excessive Heat Warning also extends west into Yuma, Lake Havasu, Bullhead City and Kingman.

A few locations north of the Valley below 4,000 feet will also be under an Excessive Heat Warning from 10 a.m. until 8 p.m. today. This will include places like Camp Verde and Cottonwood.

Slight chances for isolated storms at 10-20% are still in the forecast for the Mogollon Rim and southeast Arizona for the next couple of days but we are looking dry in the Valley until Friday. At that point, our monsoon ridge will be centered near the Four Corners allowing more moisture to stream in giving us a 10% chance of isolated storms in the Valley.

Our forecast is looking dry again as we finish out the weekend and head into next week and temperatures won't be quite as hot. By this weekend, we will drop off to 108 in Phoenix, still putting us several degrees above normal.
