Resize Text: Though late spring and summer are associated with quiescent weather and the occasional thunderstorms, the patterns remain very active in Canada (see the Weatherwise September/October 2010 issue). This is the source region for strong weather systems that occasionally expand southward into the heart of the United States, bringing beneficial rains to the Midwestern corn belt—a key region responsible for an overwhelming 70 percent of the world's corn exports. These weather systems also bring continuously changing conditions to the northern tier states and the Great Lakes Region. We'll explore some of these patterns in this issue.
