Dangerous, record-setting heat to continue from the Midwest to Southeast
Millions of Americans from the Midwest to the Southeast hoping for some relief from record-setting high temperatures this week will need to wait a few more days before that occurs.
The National Weather Service says a dome of high-pressure building in the southeastern U.S. is expected to produce well-above-average to record-breaking temperatures across the region through at least Wednesday.
That will put nearly 115 million people at risk of heat-related illnesses on Tuesday.
As the life-threatening heat continues to build, the NWS has issued Excessive Heat Watches, Excessive Heat Warnings and Heat Advisories for nearly one-third of the U.S. population.

Heat Advisories stretch from Minnesota and the upper Midwest all the way to the Gulf Coast, Southeast and parts of the mid-Atlantic.
A large part of the Ohio Valley and areas of the upper and mid-Mississippi Valley are included in an Excessive Heat Warning. That includes the cities of St. Louis, Chicago and Columbus, Ohio. In addition, Excessive Heat Warnings are in effect in the Carolinas from Raleigh, North Carolina, into parts of northeastern South Carolina.
Excessive Heat Watches are also in effect for parts of southeastern Michigan and West Virginia.
