(NEXSTAR) – Millions of Americans are expected to find themselves in the midst of stifling heat and uncomfortably sticky humidity as a heat dome covers much of the eastern U.S. this weekend.

This will be the first stretch of true summertime weather for many from the Midwest to the East Coast, said Tom Kines, a meteorologist at the private weather company AccuWeather.

“A lot of those folks have been saying, where’s summer? Well, buckle up, because it’s coming,” said Kines.

The humid conditions will make places that exceed 90 degrees Fahrenheit feel as much as 20 degrees hotter, said Kines. The heat could be particularly worrisome this weekend across wide stretches of Nebraska, Illinois, Wisconsin, and Iowa, where forecasters are warning of extreme temperature impacts.
