Nobody needs a news report to know that summer is hot, but we’re in the midst of a particular scorcher.

Data from NOAA’s HRRR Model was compiled to create a map that shows the predicted high temperatures on July 18, 2016 at 5 p.m. EDT.

The heat wave is expected to be severe, as a “heat dome” created by a high pressure ridge and extreme temperatures will trap and intensify heat in several places across the U.S.
