New England and other parts of the U.S. are experiencing record-breaking heat waves, with temperatures soaring into the 90s and above. Concord and Manchester, N.H., have recorded their longest heat waves ever, while Boston continues to endure extreme heat. Relief is expected as a cold front moves in, bringing cooler and drier air along with scattered thunderstorms. Similar patterns of heat followed by cooling trends and rain are reported in Baton Rouge, Indianapolis, Oklahoma, Memphis, Texas, Kentucky, and other regions. These areas are also experiencing heat advisories and warnings, with temperatures feeling as high as 110 degrees in some places. Long-term outlooks predict above-average temperatures into early fall, exacerbated by climate change, which continues to make summers hotter and longer.
