A heat dome is expected to bring sweltering conditions to parts of the US this week, affecting World Cup games. The heat index temperatures will combine air temperature with humidity, potentially reaching triple-digits in some areas.

This heat wave will impact World Cup host cities with open-air stadiums, including those on the East Coast. The extreme heat may pose a danger to players and fans attending the games.

Further details about the heat dome and its effects on the World Cup are available from NBC 5 Dallas-Fort Worth, including comments from a meteorologist about the significance of the heat wave.
