Look at the GFS (12Z) QPF or Rainfall Forecast:
As you can see it shows .25-.50" of Liquid falls, this storm system for Wednesday will be a little rain, but this will really be 1-4"+ of Snow possible. As soon as the new 18z data comes out, I will make a Snowfall Forecast, it appears right now; that the heaviest snow will fall northwest of Kansas City. Areas like Saint Joseph, Topeka,Marysville,etc could see 3-4"+ of Snow easily. Kansas City Appears will see 1-2"+. Below is Futurecast 3D, click to enlarge and watch the animation.
I'll have more later this Afternoon/Early Evening.
