Latest models have been consistent in advertising a strong low pressure system to eject northeastward from the south west CONUS. Models have still not resolved on a solution, with system still 84 + hours out, still time to resolve the issue.. Heavy rain could be a threat anywhere south of LSK IND SGF line.. With a sleet snow mixture north of that line. Until you reach the all snow line somewhere around and north of an IND EAX line.. NOTE: this is with current model data.. Also, ECMWF is somewhat different from other members in that it pushes the all snow line further north. Moisture and Forcing don't seem to be lacking in this system. Wouldn't be surprised to see a good 6+ up to maybe 8-12 based on current parameters.. This main snow axis would likely fall 100 miles on either side of a Kirksville, Mo - Lincoln, IL line. Will wait for more model runs. But will be worth watching.
