The National Weather Service issued another extreme heat warning for the Phoenix area Tuesday through Thursday.

According to Meteorologist Katherine Berislavich, temperatures are likely to peak around 113 degrees this week, with one key exception. Wednesday could hit 117 — enough to set a new daily record for July 9.

“This heat is going to be caused by a high pressure that is going to be strengthening over the region throughout the week. So that’s — we’re going to be drying out — and just really see that high strengthen and then will cause those temperatures to increase," Berislavich said.

Throughout the week, extreme heat warnings are in effect for 10 of Arizona’s 15 counties. Residents can call 211 for heat-related assistance.
