As the squall line crossed <br />southern Minnesota it evolved into a bow <br />echo system that expanded in scale and <br />raced east across the southern Great Lakes <br />before finally dissipating over central New <br />York after sunrise on Sunday, May 31st. This <br />bow echo system produced one of the most <br />dangerous and costly derecho events in the <br />history of the Great Lakes region. The <br />"Southern Great Lakes Derecho of 1998" <br />adversely affected millions of people on the <br />weekend after Memorial Day. Many <br />casualties and record amounts of damage <br />occurred. <br />
