[vc_row][vc_column][vc_column_text css=””]The largest heat dome on the Earth right now is over Tennessee—larger than what is sitting over the Sahara Desert or Middle East. A heat dome is a weather event where a large area of high atmospheric pressure traps hot air over a region like a lid on a pot. Extreme heat caused the air to expand and rise high into the sky. Warm moisture from the Gulf of Mexico also feeds the high-pressure dome. The heat dome over Tennessee today has risen to 19,665 feet. Over the Sahara Desert, it is 19,491. See the other heat domes below and how we compare. We’ll continue experiencing high temperatures into the weekend with some relief coming next week. Stay hydrated if you spend time outside.
