Heat to bounce back quickly over north-central US into early week
While all-time record highs were set in Southern California to end the week, sweltering conditions will continue to make a comeback in the north-central United States through early week.
Millions of people in the region will not be able to get to enjoy an extended stretch of cooler and less humid air.
"Heat and humidity are forecast to build from west to east across the Plains through Sunday and the Mississippi Valley early this week," AccuWeather Long-Range Meteorologist Max Vido said.
Highs in the 90s have surged back across the High Plains to start the weekend and will continue to expand toward the upper and mid-Mississippi River into Monday.
With humidity also increasing, the heat will help to fuel severe weather across the far northern Plains this weekend. The strongest thunderstorms will be capable of producing damaging winds, hail and flooding downpours.
Later Sunday, severe weather will threaten Aberdeen, South Dakota, to Duluth, Minnesota.
Highs are projected to be in the lower to middle 90s F in Omaha, Nebraska; Des Moines, Iowa; and St. Louis and Kansas City, Missouri; most days this week.
Highs will be within a few degrees of 90 F in Fargo, North Dakota, and Minneapolis.
Farther east, high temperatures will trend upward through the 80s to near 90 F in Chicago, Detroit, Indianapolis, Cincinnati and Cleveland to start the week.
While many may think that these temperatures are typical for the middle of July, they are projected to be 4-8 degrees above average in many cases.
Later in July, there is the potential for another re-arrangement of the hot versus cool air across the U.S.
"It is possible that more substantial cooling develops over the Midwest past the middle month," said AccuWeather Lead Long-Range Meteorologist Paul Pastelok.
Pastelok points to the likelihood of a typhoon curving away from eastern Asia this week.
"When typhoons do this, they usually create buckles in the jet stream that allow cooler air to plunge southward from Canada and into the North Central and/or Northeastern states a week later," Pastelok said.
