A heat dome has settled over a large swath of the Southwest, bringing triple-digit temperatures to millions of Americans.
“Widespread highs of 100F+ can be expected across the southern High Plains and Southwest, with higher temperatures possible over Arizona,” an alert from the NWS said.
Cities across Southern and Central Arizona are already seeing sky-high temperatures, and are expected to see the worst of the heat in the middle of this week, NPR reported. Arizona is supposed to be hot during the summer, but this week’s temperatures are alarmingly high. “The high temperature this afternoon at Phoenix Sky Harbor Airport was 112°, which is five degrees above normal,” Phoenix’s NWS station tweeted yesterday.
Very hot temperatures will continue through all of next week with the worst of the heat starting the middle of next week. Make sure to practice heat safety when heading outdoors. #azwx #cawx pic.twitter.com/yrfwC8Fa1T

Nearby Texas isn’t going to be spared, either. Communities that had to sweat it out during a June heat wave that strained the state’s grid are in for another round. Southern Texas is expected to see heat indices over 110 degrees Fahrenheit (43.3 Celsius), according to the NWS alert.
South Florida is also going to experience sweltering heat this week. The combination of high temperatures and high humidity over the region will also bring heat indices up to around 105 degrees Fahrenheit (40 Celsius). The heat advisory over that part of the state is expected to last until this Wednesday.
“Dangerous conditions are possible if citizens are unable to find relief in air-conditioned buildings,” the NWS alert warned.
