This event continued from the last day of February. A mixed bag of winter precipitation produced very hazardous travel conditions. The precipitation was mainly snow northwest of a line from Carbondale to Mount Carmel. A swath of heavy snow fell across Wayne and Jefferson Counties, including the Mount Vernon area. The co-operative observer near Mount Vernon measured 6.5 inches of snow. A trained spotter several miles south of Mount Erie in Wayne County measured 6 inches. Amounts tapered off toward the south. Only about 2 inches was reported near Pinckneyville and Du Quoin (in Perry County) and at Dahlgren (in Hamilton County). Along and southeast of a line from Carbondale to Mount Carmel, the precipitation was mainly in the form of light sleet and freezing drizzle. Amounts were generally one-tenth inch or less. Little if any wintry precipitation occurred in the southeast corner of the state, from Vienna south and east to the Ohio River. The precipitation was caused by a surge of warmer air aloft moving north across the region. The warmer air aloft moved over a shallow layer of cold air near the surface. As the depth of cold air decreased, the precipitation changed from snow to sleet and freezing rain, then finally to liquid rain or drizzle.
