It’s been a relatively cool summer in the Midwest and even for portions of the Southeast, but things are about to get hot in parts of the region. Very, very hot. In fact, it’s already starting to get there.

Temperatures are going to rocket into the middle and might even crack the upper 90s in the St. Louis metro area, prompting the National Weather Service to issue an excessive heat warning for the city from Wednesday all the way through Sunday. It wouldn’t surprise me at all to see the watch be expanded in the coming days to other portions of the Midwest and deep South.
It’s not just St. Louis that’s going to see the oppressive heat, however. From Oklahoma City to Kansas City and all the way into Atlanta, the next few days are going to be scorching. Here’s a look at forecast highs for a handful of those soon-to-be-sweaty cities over the next few days:




But as we all know here in this part of the country, it’s not necessarily the heat that’s the worst. It’s the humidity.

Dew points (a chief measure of the moisture in the atmosphere) are going to be in the mid-to-upper 70s in the St. Louis area, and it’ll be increasing as the week wears on. Anything above 60 is noticeable. Seventy or above is oppressive humidity- and 75-or-above is insert-explitive-here level humidity. Expect similar humidity levels into the southeast, from Charlotte to Nashville and on westward to Dallas- and it’s going to stay with us for a while.

Spreading from west-to-east, a ridge of high pressure will allow warm, moist air from the Gulf of Mexico to advect north, spreading the oppressive heat and humidity from the south and into the area. Indications are that this heat won’t break until the end of the weekend (from west-to-east), starting on Sunday and . But even then, forecast highs will remain in the upper 80s to lower 90s in the region. So while it’ll ‘cool’ off, you’re not exactly going to break out the parkas in Kansas City yet.

Remember to stay hydrated and limit strenuous outdoor activity – get up an extra hour early for that morning run, and wear light-colored clothing! As always, we’ll keep you posted with all the latest right here on WeatherNation and
