The heat that first gripped California, Nevada, and Arizona is now marching east. States like Texas, Kansas, Missouri, Illinois, and even the Dakotas are next in line, turning what should be mild spring days into something far more extreme.
A heat dome acts like a lid in the atmosphere. High pressure traps hot air near the ground, blocks clouds from forming, and allows the sun to beat down without relief—intensifying every hour people spend outside.
In places like Texas and Nevada, temperatures are expected to climb to or exceed 100°F, shattering records that have stood for decades. It’s not just heat—it’s history being rewritten in real time.
