An October heat wave throughout much of the eastern half of the United States has broken records and closed some schools.

The heat is expected to continue Wednesday with temperatures from the South to the Mid-Atlantic forecast to be 10 to 20 degrees above average, according to the National Weather Service. Parts of the North will see temperatures in the low 90s, while farther south, they will reach the high 90s.

The scorching temperatures led some areas to close schools, including in Columbus, Ohio, that state’s largest school district.
