Trapped Under a Heat Dome: Why This Summer Feels Like an Oven

Hey everyone, I just wanted to take a moment to talk about what’s going on with the weather lately—because let’s be honest, it’s not just hot out there, it’s brutal. You’ve probably seen the heat advisories popping up all over the place, and you’re not imagining things—it really is that bad. Right now, a massive heat dome is spreading across nearly half the U.S., impacting over 160 million people. If it feels like we’re baking under a hairdryer turned to full blast, that’s basically what’s happening.

So, what exactly is a heat dome? Imagine a massive lid of high-pressure air sitting over us. This air sinks and compresses as it nears the ground, and in doing so, it traps heat like a sealed oven. The more the air compresses, the more those air molecules start bouncing around like a mosh pit—literally bumping into each other and creating more heat. Meteorologists say this effect also stops clouds from forming, meaning there’s little relief from the sun. So yeah, endless blue skies might look pretty, but they’re also making us feel like we’re melting.

And then there’s the humidity. With all this heat, moisture from the soil and crops—especially cornfields in the Midwest—is evaporating and hanging in the air, making everything feel even stickier. It’s what some folks call “corn sweat.” It may sound funny, but it’s making conditions downright miserable. When it’s 100°F outside, the added humidity can push the “feels like” temperature to 110°F or more. For the human body, that’s a dangerous combo. Sweating stops being effective, making it harder for us to cool down naturally. That’s especially risky for kids, seniors, people with heart conditions, and anyone working outdoors.

One of the worst parts? Nights aren’t giving us a break. Temperatures are staying stubbornly high, sometimes 15 degrees above average, meaning homes don’t cool down like they should. For people without AC—or those who can’t afford to run it—these nights can be just as harmful as the sweltering days. That overnight heat buildup adds more and more stress to the body. And yes, this is yet another fingerprint of climate change. Scientists have found that events like this heat dome are now five times more likely than they used to be because of human-caused climate warming.

So if you’re under one of these advisories, take it seriously. Stay hydrated, limit your time outdoors, check in on vulnerable neighbors, and try to keep cool however you can. This isn’t just a regular summer heat wave—it’s something much more intense, and it’s likely to stick around longer than any of us would like. Stay safe out there, folks.
