What causes a heat dome?

In short, a heat dome is created when an area of high pressure stays over the same area for days or even weeks, trapping very warm air underneath – rather like a lid on a pot. The jet stream is a core of strong winds high above the Earth’s surface that helps to develop and steer areas of low pressure around.
