A major winter storm brought primarily heavy snow and sleet to southern Illinois. The precipitation changed from freezing rain to sleet and then to snow. The wintry precipitation slowly progressed southeast across southern Illinois, starting by mid-morning in Mount Vernon and reaching the southern tip of the state by mid-afternoon. Storm total accumulations ranged from 5 to 12 inches. About a foot of snow fell along and north of a line from Du Quoin in Perry County to Mount Carmel in Wabash County. Between 8 and 12 inches fell across most of the remainder of southern Illinois, including Marion, Carbondale, Harrisburg, and Carmi. Accumulations were from 5 to 7 inches along the Ohio River from Cairo to Metropolis to Hardin County due to large amounts of sleet and freezing rain. Before the changeover to snow, there was about one-quarter inch of glazing from freezing rain, along with about one-half to one inch of sleet. Isolated power outages were reported. Once the precipitation changed to snow, it fell heavily at times. Visibility was occasionally one-quarter mile in heavy snow, with snowfall rates at least an inch per hour. A trained spotter in White County reported 1.5 inches of snow in an hour. In the area that received the heaviest snow, unplowed farm roads were impassable without four-wheel drive. In all areas, roads became very slick and hazardous as temperatures dropped through the 20's. Numerous accidents were reported. Non-emergency travel was not advised by some county officials. An arctic cold front swept east across the region, bringing much colder air. As the depth of the cold air increased behind the front, precipitation changed from freezing rain to sleet and then snow. A pair of disturbances in the upper levels of the atmosphere moved northeast across the region, causing wintry precipitation to become heavy at times.
