PHOENIX — An excessive heat warning will run through Friday for the metro Phoenix area as temperatures are expected to exceed 110 degrees.

The warning goes into effect starting at 10 a.m. on Wednesday and lasts through 8 p.m. on Friday.

The expected high temperature on Wednesday is 110 degrees, followed by 112 degrees on Thursday and Friday, according to the National Weather Service.

While the excessive heat warning is expected to expire on Friday night, it appears the hot temperatures will remain in the forecast through the weekend.

The mercury is expected to reach 107 degrees on Saturday, followed by a high temperature of 106 degrees on Sunday.

Storm chances are back in the forecast as the weekend comes to a close with a 20% chance of showers and thunderstorms on Sunday night.

Chances for a storm increase to 40% on Monday night.

The string of hot weather follows what has been a cooler than usual month for the Valley, driven by a wet monsoon season.

Temperatures in the Valley have surpassed the normal high only eight times so far in August, as opposed to 15 days below average, according to the National Weather Service.

Five days with temperatures at least 10 degrees below normal were also recorded.

Phoenix through Aug. 21 has had 17 days of measurable rainfall, the second-most during that time span, according to the National Weather Service.

When accounting for the entire monsoon, which comes to a close on Sept. 30, the days of measurable rainfall so far this season is tied for 14th-best.

It has been a welcome sight for Valley residents this summer after last year when August was the hottest month ever recorded in Phoenix history, as the average temperature over the course of the month was 99.1 degrees.

We want to hear from you.
