Maps Show the Cities about to Experience Extreme Humidity and Heat

Ohio will be impacted

Over the next two weeks, extreme levels of humidity are forecast to hit around 40 states, with the first wave of very muggy weather building in central and eastern states through Thursday. Across the country, around 170 million people will also experience temperatures above 90 degrees.

Burgeoning humidity contributed to deadly downpours in West Virginia last weekend, and it will fuel severe storms that are expected to hit the Plains and Midwest through Wednesday before reaching the East Coast on Thursday.

The high humidity and temperatures this week are being driven by above-average ocean temperatures, and southerly winds blowing from these areas. And there’s more to come. A second, stronger surge of potentially dangerous heat and humidity is expected this weekend into next week as a heat dome is likely to form.
