@washingtonpost: More than half of the U.S. population is under excessive-heat warnings or heat advisories into the weekend, stretching from the beaches of Southern California to Maine’s south coast. A large percentage of the 170 million people under these heat alerts are concentrated from the central states to the Interstate 95 corridor of the Northeast, which is bracing for its hottest weather of the summer so far. On Thursday, some of the most brutal heat is focused in the central states. St. Louis is under an excessive-heat warning, with highs in the low 100s and heat indexes over 110 degrees expected. Minneapolis, also under a warning, is forecast to reach the upper 90s Thursday with heat indexes 10 degrees higher. #hotones #lorde #heatwave #firstwefeast #earth #seanevans
