This is the latest NAM. The forecast models keep pushing the heaviest amounts of snow south and east. Not to say KC won't get hit, but not as hard as Central and SE MO will.
This is the QPF. If all precipitation falls as snow you can assume a ratio between 10-15:1 if all precipitation fell as snow. More likely close to 10-12:1 given the temperatures it will be falling at. These numbers will be obscured at points at or south of the rain snow line. Points northward it should be a pretty accurate representation.
