A potent low pressure system moved across Missouri and southern Illinois Nov. 20th and 21st, bringing the season's first snowfall to much of the area. Widespread snowfall totals of 6 to 12 inches were found across northern Iowa and the Wisconsin-Illinois border. Isolated higher amounts of 14 to 16 inches were reported. Strong northerly winds developed as the system moved off to the northeast, which created patchy blowing and drifting snow. Rain prevailed for much of the night in parts of northeast Missouri and west central Illinois limiting snowfall amounts in those areas to generally under an inch.
