Outlook

As very hot temperatures persist this week, be aware that an Excessive Heat Warning is in effect for the lower elevations of Yavapai, Coconino, and Navajo counties. All warnings will last through at least Saturday, June 19th. Temperatures in the Excessive Heat Warning areas will range from 100-116 during this period.

Very hot temperatures will continue through Friday before a slow cool down heading into next week as high pressure weakens and shifts to the south. Enough moisture has made it’s way into Arizona for the development of isolated afternoon and evening thunderstorms through Saturday. Brief heavy downpours, cloud-to-ground lightning and gusty winds to 45 mph will be possible.
