Excessive heat warning set for Thursday, Friday in Valley as temperatures could reach 113 degrees
PHOENIX — A work week that started with cleanup from a strong monsoon storm is expected to end with sweltering temperatures as an excessive heat warning was issued for metro Phoenix.
The excessive heat warning goes into effect Thursday at 11 a.m. and runs until Friday at 8 p.m., with temperatures forecast to rise above 110 degrees each day, according to the National Weather Service.
The high is expected to be 112 degrees on Thursday and increase slightly to 113 degrees on Friday.
High temperatures are then forecast to dip to 108 degrees on Saturday and 104 degrees on Sunday.
The monsoon season may also provide some relief over the weekend as there is a 20% chance for storms on Saturday night that increases to 40% by Sunday night.
The last excessive heat warning in metro Phoenix came on Saturday, but storms that evening and on Sunday night cooled off the Valley.
It doesn’t appear storms will lower the temperatures this time as rain is not forecast for Thursday or Friday.
The Salvation Army will activate 11 heat relief stations around the Valley from 11 a.m. to 5 p.m. on Thursday and Friday. Locations can be found on the organization’s website.
As has been the case throughout the summer, Phoenix will close Camelback Mountain’s Echo and Cholla trails and all trails associated with Piestewa Peak Trailhead from 11 a.m. to 5 p.m. while the excessive heat warning is in effect to reduce deaths and injuries as well as protect rescue personnel.
