Weather History for December 20
 
1836
A famous cold wave occurred in central Illinois. A cold front with 70 mph winds swept through at Noon dropping the temperature from 40 degrees to near zero in a matter of minutes. Many settlers froze to death. Folklore told of chickens frozen in their tracks and men frozen to saddles. Ice in streams reportedly froze to six inches in a few hours. (David Ludlum) (The Weather Channel)

1987
Heavy snow fell in the northern mountains of Colorado, with 15 inches reported in the Mary Jane ski area. Strong and gusty winds prevailed from the Northern High Plains to the Great Lakes. Winds gusted to 54 mph at Buffalo NY, and reached 66 mph at Livingston MT. Rain, freezing rain, sleet and snow fell across New England, with up to seven inches of snow in Maine.
