Record Heat Dome Sweeps Nation, Issuing Extreme Weather Warnings Coast-to-Coast

Dangerous heat warnings are widespread across the United States, with record-breaking temperatures and a heat dome expected to settle over major cities. The National Weather Service reports that millions of Americans are under "major" or "extreme" heat risk as temperatures soar far above seasonal averages. The most severe weather conditions are anticipated in the Midwest and Northeast, with heat index warnings expected up to 107 degrees Fahrenheit in some areas. While records have been broken across the Northern Plains, heat advisories remain in place from California to the Upper Midwest through at least Wednesday. Health experts warn that the danger is heightened by the lack of overnight cooling, making the body unable to recover from daytime heat. Authorities urge residents to stay hydrated, avoid outdoor activity during the peak heat hours, and check on vulnerable family members, including the elderly. Beyond the heat, the region faces dangerous air quality due to smoke from hundreds of active wildfires. Scientists note that extreme heat events are becoming more intense and frequent due to human-caused climate change.
