This past Monday, a fast moving storm called a derecho, with hurricane force winds, hit the upper Midwest. Crops were flattened and grain bins were destroyed,. According to Agriculture.com, 10 million acres of crops were affected in Iowa alone and in the entire Midwest, possibly 200 million to 400 million bushels of corn may have been lost. It's a horrible loss to farmers, but the storm also showed it's power by causing Lake Michigan to actually slosh back and forth for the last several days.

According to MLive.com, lake levels at South Haven rose a foot and a half as the storm approached and then fell. The same thing happened on the other side of the lake in Milwaukee. Since then, water levels have gone up and down in a diminishing pattern as Lake Michigan sloshed back and forth.

Crazy, huh?
