The heat dome that has continued to bake the Eastern U.S. with high temperatures in the 90s and 100s will finally begin to subside. After many days of daily records broken, relief is finally on the way. On Sunday, much of the east will still see highs in the 80s and 90s, with parts of the mid-Atlantic seeing heat indices still over 100. By Monday, temperatures across the Northeast will drop to the 70s, while the South hovers around 90. Watch for the latest forecast.
