Heat Dome Weakens, Bringing Relief to Midwest

A heat dome is a weather event where hot air gets trapped, causing very high temperatures.

Recently, this happened in the northern Plains and upper Midwest.

But now, the heat dome is getting weaker, and cooler air from Canada is coming in.

This will bring some relief from the heat over the weekend and early next week.

So, people in these areas can expect nicer weather soon.
