Hundreds of heat records set across U.S. this week

A severe heat wave is sweeping across the Midwest and East Coast, breaking heat records in over 280 locations across the US. Nearly 130 million people are under extreme heat warnings or heat advisories, with temperatures expected to remain high until Friday. A "heat dome" is driving the extreme conditions, trapping warm and humid air over vast areas. Springfield, Ohio set an all-time heat record of 104 degrees, while other locations such as Bumfield Lake, Massachusetts, and Lebanon, New Hampshire also broke records. New daily heat records were set in at least 50 cities in the Eastern US on Tuesday alone. Cities such as New York City, Baltimore, and Newark also experienced record-breaking temperatures. Heat advisories remain in place in over a dozen states, including North Carolina, Illinois, and Pennsylvania. The prolonged and intense heat wave is expected to continue until Friday, posing a risk to millions of people. The extreme heat can also impact infrastructure and daily life, with some schools even considering "heat days" instead of snow days. The heat wave is expected to continue into the weekend, with no relief in sight.
