 21 December 1944 → The Battle of the Bulge lasted from December 16, 1944 to January 25, 1945. By this time Germany was clearly losing World War II and Hitler was hoping to regain advantage if the attack would occur in bad weather to prevent the Allied Air Forces from being effective. As the Americans occupied the strategic position of Bastogne, the German army surrounded the city. However because of bad weather, planes were unable to fly and provide supplies by air drop to the American Forces. On December 29 the weather finally cleared up and much needed supplies were received. The Americans then launched a counteroffensive, but soldiers had to fight the cold and snow as well.
 21 December 1967 → The City Hall and a large portion of the business district of Potosi, MO was destroyed by an F4 tornado. There were 52 injuries and 3 deaths.

A blizzard swept through southeastern South Dakota, dropping over 16 inches of snow in places. The snow combined with winds gusting to 60 mph at times, thus producing blizzard conditions. Interstates 29 and 90, as well as most other roads east and south of Sioux Falls were closed. There were hundreds of traffic accidents in the Sioux Falls area alone. The hospital emergency rooms were swamped with victims of automobile accidents and injuries sustained while shoveling heavy snow. Two men died from heart problems while shoveling the snow.
