MU's Elliott on the remainder of summer:
By the end of next week, the large, semi-permanent Jet Stream ridge that has been responsible for the recent stretch of brutal, record-breaking heat cross the southwestern United States may shift into the central U.S. and expand its grasp over most of the nation. If this comes to fruition, then a bonafide heat wave could occur during the last few days of July, and more extreme heat could be lurking in August. Odds favored the second half of this summer being much hotter than the first, and it certainly appears that that will indeed be the case.
