Tue-Mon, July 19-25th Heat Wave Update #3

​(8:30PM Tuesday - 7/19/22) As has been the case much of this summer, a large ridge is expected to flex across the Inter-Mountain West, Plains and Southeast once again, this week on through this weekend, and perhaps into portions of next week. As has been the case several times this summer, hot and humid conditions are expected to expand into portions of the region and state as a product of this ridge, bringing another heat wave to the state and region during this time.
