Under the Dome of High Pressure
Temperatures are sizzling across the Plains while that part of the U.S. remains under a “dome” of high pressure. While not an impenetrable bubble that severs all contact with the outside world, a heat dome does “trap” hot air underneath it over the course of several days, often over a large area.
