A ‘heat dome’ is sweeping across the US this weekend, bringing prolonged sweltering temperatures, expected to reach 15 to 25 degrees Fahrenheit above what’s normal for this time of the year.
A ‘heat dome’ occurs when high pressure traps hot air underneath it and usually lasts a number of days. Combined with high humidity, heat indices are forecast to soar - the highest indices are predicted to be felt across the Corn Belt and Midwest, topping 110 degrees Fahrenheit (43 Celsius).
