A dangerous heat wave is set to embrace much of the United States, with the National Weather Service warning of scorching temperatures and high humidity as we approach the Fourth of July weekend. The heat dome is expected to affect around 200 million people, bringing temperatures soaring between 90 to 100 degrees across the Midwest and East Coast. Several regions, including Minneapolis and South Bend, are bracing for extreme heat, with officials urging residents to prepare for potential health risks associated with the prolonged heat. Weather alerts have been issued across many states as meteorologists track the combination of two heat domes and anticipate severe thunderstorms alongside the rising temperatures. As we head into the holiday, expect the hottest days of the year and be prepared for the impacts of this significant weather pattern change.
