Extreme Heat Wave Breaks Records Across Central U.S.

A heat dome is causing oppressive heat across the Midwest and South, with temperatures over 100 degrees affecting over 100 million people.
Numerous heat records have been tied or broken in cities like Chicago, Dallas, and Minneapolis, with heat indices approaching 120 degrees.
Overnight low temperatures are remaining dangerously high, giving little relief.
The heat wave is expected to continue through the week before shifting west and south on Friday.
Heat is the number one weather-related killer in the U.S., and people are advised to limit outdoor exposure and stay hydrated.
