Here is some information.
Eli Jacks, a meteorologist at the National Weather Service tells the Associated Press a heat dome is a kind of perfect storm of sizzling summer weather exacerbated by relatively cloudless skies and the higher angle of the sun in the summer. "When a high pressure system develops in the upper atmosphere, the air below it sinks and compresses because there's more weight on top, causing temperatures in the lower atmosphere to heat up," he tells the news agency. "The dome of high pressure also pushes the jet stream and its drier, cooler air, farther north — it's now well into Canada — while hot, humid air from the Gulf of Mexico circulates clockwise around the dome, traveling farther inland than normal."

Combined with generally clear skies and the sun's higher summertime angle, "it gets really hot," Jacks said.
The formation of the dome also explains why conditions in, say, North Dakota aren't much different this week than in Houston. The big difference is that people in Houston are accustomed to hot weather. Those in the north are not.
