Widespread snowfall blanketed southern Illinois during the night of the 24th into the early morning hours of the 25th. Heavy snowfall occurred along and west of Interstate 57, or roughly along and west of a Mount Vernon to Marion to Cairo line. Snowfall in those areas was generally 4 to 5 inches. Elsewhere, snowfall was in the 1 to 3 inch range. Specific snowfall amounts included 6 inches at Murphysboro, 5 inches at Carbondale and Ava (Jackson County), 5 inches at Cobden (Union County), 4 inches at Sesser (Franklin County), 4 inches at Marion and Mount Vernon, 3 inches at Junction (Gallatin County), 2.5 inches at Harrisburg, and 1 inch at Mount Carmel and Fairfield. The heavy, wet snow was enough to bring down some tree limbs and power lines in the forested areas of Union and Jackson Counties, where 5 to 6 inches fell. The power outages were isolated, and mostly from Ava in northwest Jackson County to the Shawnee National Forest area of Union County. Snowfall rates were quite heavy for a couple hours, even around an inch per hour. Roads were snow-covered and slippery during the heavy snow, with numerous vehicles sliding off the road. Temperatures rose above freezing soon after the snow ended, so treated roads improved rather quickly later in the morning. The snow occurred northwest of a surface low that moved from Memphis, TN to Murray and Owensboro, KY. Once temperatures cooled during the evening of the 24th, enough cold air remained in place for widespread snow.
