Temperatures are expected to remain high in certain regions. A heat dome is the cause of this sweltering weather, which may lead to severe storms and flooding. Overnight lows will be higher than average, potentially breaking records.

Some areas have already experienced extremely hot days, with the heat index making it feel even hotter. The heat dome's effects will be felt across a wide area, bringing warm weather to parts of the country.

Further information about the heat dome and its impact is available from Meteorologist Tyler Ory, CNN.
