It just keeps getting HOTTER across America…..
In addition to its magnitude, which will be dangerous for some, the heat will be notable for its longevity. Phoenix, for example, has already logged 10 days in a row at or above 110 degrees — the seventh-longest streak on record — and the forecast calls for highs in the 111-to-117-degree range until further notice. That could catapult the heat-prone city into its longest ever streak above that level.
The heat will be dry yet punishing in the Southeast, while the south-central U.S. and southern Plains will contend with humidity drawn in from the Gulf of Mexico. That will overlap with the hot temperatures to push heat indexes — measures of how hot it feels, taking into account temperature and humidity — into hazardous territory.
