Event Summary

A widespread and dangerous heat wave is building across the United States, with triple-digit highs expected in the Southwestern United States and Great Plains before spreading eastward under a dome of high pressure that could trap oppressive temperatures for a week or more. The heat dome is expected to affect as much as two-thirds of the continental US, with temperatures 15-25°F above normal. The United States — National Weather Service predicts over 90 local temperature records will be tied or broken. The heat wave has already killed more than two dozen people, including at least 29 in United States — New Jersey, 4 in United States — Chicago, and 1 in United States — Mississippi. Climate change is cited as a contributing factor, making heat waves more intense and longer-lasting. The El Niño–Southern Oscillation event is expected to become very strong by fall.
