Millions of Americans are under heat warnings heading into the weekend as temperatures are expected to soar in most of the United States. The sky-high temperatures are expected to feel even hotter as dew points will likely reach near record-breaking numbers.

Upwards of 85% of the population is expected to experience temperatures higher than 95 degrees Fahrenheit on Saturday with dew points ranging from 72-85 degrees. The highest recorded dew point temperature in the United States was 88 degrees in Minnesota in 2011, which combined with a 95 degrees temperature would express a heat index of 126 degrees. Factoring in the high dew points, regions from Kansas City, to Washington, D.C., to New York City, and Boston are expected to feel heat indexes of higher than 110 degrees this weekend.
