With the help of Jaleesa Lopez, 10, far right, her brother, Orlando Celaya, 1, sprays their brother, Marsaleno Oliver, 7, while cooling off in the splash pad at Catalina Park on July 23, 2018. Jessica Lopez, their mother, said the air-conditioning in the house broke down and she brought her kids to the splash pad to cool off. 

On this day 18 years ago, temperatures in Southeastern Arizona reached 111 degrees. Tucson hit 107 degrees.

Tucson might not break any records, but today's high temperatures are expected to come close, the National Weather Service says.

The service has previously said that the temperatures we've been experiencing are above normal for September.

Similar temperatures are expected to continue tomorrow.

Always remember: It's important to stay hydrated and protected from the sun.
