There's a quickly worsening drought right now in the upper Midwest. In just the last week, "extreme" drought expanded from 7.7 percent to 25.1 percent of North Dakota, the hardest-hit state. And next week, a multi-day heat wave is on the way. It's expected to reach as high as 107 degrees Fahrenheit in parts of the Dakotas, more than 20 degrees above normal.
Why does that matter? For one, it might seriously affect this year's wheat harvest there.
