2014: The ‘One-two Punch’ Midwest Derechos of June 30 to the early morning hours on July 1st. A pair of Derechos brought parts of the mid-Mississippi Valley and Great Lakes an unusual “one-two punch” on June 30 – July 1, 2014. The Derechos produced swaths of significant wind damage that extended intermittently from far eastern Nebraska through much of Iowa, northern Illinois, and southern Wisconsin into northern Indiana and southern Lower Michigan. The most continuous and intense damage occurred over eastern Iowa, northern Illinois, and northern Indiana, where some locations were affected by both derecho-producing storm systems. The Derechos also were responsible for widespread disruption of air travel through Chicago’s O’Hare International Airport. Click HERE for more information from the Storm Prediction Center.

1842: A late-season snowstorm struck New England. Snow fell during the morning and early afternoon, accumulating to a depth of ten to twelve inches at Irasburg, Vermont. Berlin, New Hampshire was blanketed with eleven inches of snow during the day. Snow whitened the higher peaks of the Appalachians as far south as Maryland.
