"Extreme temperature drops often characterize the most severe storms. The Armistice Day Blizzard, which struck the Midwest on November 11, 1940 was such a storm. Armistice Day, now called Veterans Day saw very mild conditions. Early afternoon temperatures were in the 60’s. Many hunters took a day off work and went to the waters of the Mississippi to take advantage of the perfect Duck Hunting conditions. Many did not take cold weather outfits. Conditions deteriorated rapidly. The temperature dropped as much as 50 degrees in minutes, 50 mile per hour winds assailed the unprepared. That evening and into the next day sleet and then up to 27 inches of snow fell, drifts formed. Boats on the river were swamped and men drowned. Others were stranded on islands. Many who got to shore were unable to get their vehicles out. Some took shelter under overturned boats. The result was that many froze to death. The official death toll from the storm was 145, which included 66 sailors on the Great Lakes. 13 died in Wisconsin."
