Okay kiddo, so sometimes when it's really hot outside and the air is really dry, something called a heat burst might happen.
A heat burst is when hot air suddenly rushes down from the sky and hits the ground really hard. It's kind of like a big sneeze, but with hot air instead of snot.
When this hot air hits the ground, it can make the temperature go up really quickly, sometimes by as much as 20 degrees Fahrenheit in just a few minutes! That's like going from room temperature to standing in front of an open oven.
This can be really dangerous for people and animals who are outside, so it's important to stay hydrated and try to find some shade or cool air if you can. But sometimes, Mother Nature just likes to remind us who's boss and there's not much we can do about it.
