(NBC) – A “major heatwave” is expected to bake two-thirds of the nation through this weekend, with forecasters calling for temperatures to soar across much of the central and eastern U.S., the National Weather Service said. Many in those areas could see the hottest temperatures of the year, thanks to a large dome of high pressure that will send temperatures climbing in the coming days, the weather service said. Already on Tuesday night, an estimated 34 million people were under heat advisories and another 21
million were under excessive heat warnings, according to the weather service. The affected areas stretched from Texas to much of the Plains. The East Coast is feeling the heat, too, with advisories issued from South Carolina to New Jersey. Although he didn’t declare a heat emergency, Boston’s mayor on Tuesday warned residents to prepare for the heat and take precautions for temperatures expected to be between 85 and 97 degrees, with the hottest forecast on Saturday. With the humidity, it could feel as hot as 105 degrees, the mayor’s office said. FULL REPORT
