Searing Heat Threatens Grids, Health Over Nearly Half the US

Nearly half the US will wilt under hot, sticky conditions through the bulk of the week as temperatures and humidity soar from Chicago to New York City and New Orleans, boosting power demand and raising health risks.

Heat advisories and extreme heat warnings stretch from Nebraska to Long Island and from New Hampshire to northeast Texas. Monday’s high in Central Park is forecast to reach 96F (36C), but with humidity it will feel closer to 100F or more. Chicago will likely reach 91F and feel closer to 102F, the National Weather Service said.
