Snows. Right now i will say the heaviest snows will fall from about KC ne up into norther MO/Eastern NE and into all of IA and southern MN east to southern WI and northern IL. Someone here is gonna see well over a foot of snow when all is said and done. And as well expect blizzard like conditions in the snow areas. The problem is the snow will lose its intensity as it heads east into the direr air towards the lakes and farther away from the Low pressure itself which should make its way thru Southern MO and into Southern IL and then east from there into the OV. Most areas in the Dark blue should see atleast 4 inches of snow from this event.
ICE/Mixed precip. ST.Louis looks to be ground zero for a sig Ice event as does alot of areas within the red area circled on the map below. Someplaces as far north to the south side of KC could see some icing as well.
Areas farther east into IN and eastward right now is my first guess as to what the precip types may be like. Areas farthest east into OH and western PA could get a good dumping of snow either way as the system transfers its energy to the coast and the cold air rushes in before the heaviest precip gets thru these areas. I expect the cold air to hold on in alot of these areas as was the case last weekend however as like last weekend some of the layers above will probably go above freezing causing a mixed bag of precip especially from i70 south. Hard to say at this point exactly where the Snow/Mix and Rain lines will be however as the models are showing the heaviest precip wont be arriving untill most levels of the atmosphere is safely below freezing from about i70 north.

So anywho, I think I'll take myself to bed now....and see how much ice I wake up to later on... can we say bust?
