Shifting the Heat
It's been a brutal start to summer, only "officially" two weeks old. June ended with a record-smashing heat wave from the Rockies to the Southeast, rewriting not only monthly, but all-time record highs in dozens of locations from Denver to Atlanta.
The graphic above depicts a shift in the upper-air wind flow we're expecting by early next week.
Namely, the dome of high pressure aloft, and, epicenter of the heat, will shift west into the Great Basin. Meanwhile, a dip in the jet stream will effectively erase the excessive heat from the Midwest and East for awhile.
The heat relief starts as soon as Saturday in the Upper Midwest. Highs should hold in the 70s or low 80s in the Dakotas, Minnesota, Wisconsin and northern Michigan, albeit accompanied with scattered thunderstorms.
The most significant change may be felt Monday in the most heat-weary belt from Kansas to the Ohio Valley. After days of triple-digit heat, Monday's highs may be held in the 80s or, at most, low 90s in Kansas City, St. Louis and Cincinnati.
These highs may not sound "cool", per se, but they're close to early July averages.
This pattern change may also bring another form of relief: rain
