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.
Even regions like the Midwest and Great Plains will feel it. Areas that usually see 40–60°F in March could surge into the 80s, creating a sudden and unnatural jump that many aren’t prepared for.
