With a Thursday 6 a.m. to Friday 1 a.m. duration, some light sleet & freezing rain accumulation is likely Thursday morning-near midday for part of the viewing area. There may even be brief plain rain in parts of the area with highs 33-34. It should go to all snow & continue through the afternoon as temperatures fall back to 30-31. Cold, raw northeast to north winds at 10-15 mph will make for a raw, mid-winter-type day.
Some impacts to travel will occur.
4-8" of snow will occur over southern Illinois, western Kentucky & southeastern Missouri with substantial sleet & freezing rainfall accumulation farther east.
Reason for such snowfall there & not here is that as system moves northeastward, Nor'Easter will develop along the East Coast & moisture & energy will be transferred from our system to that one.
This will cut wintry precipitation totals here.
