I am not going to speak for TV Meteorologists since I am not one and not there to see what they are looking at and how their decisions are made on what to go with. Regarding this past weekend storm, the model guidance overall were having trouble with the split flow. This involved a system moving across the Great Lakes and another one sliding across the Gulf Coast States. What appeared to have happened was the systems phased a bit faster allowing warmer air to be advected farther north and west, therefore moving the area of lift in the atmosphere farther inland. There was mesoscale banding signatures showing up in the guidance, but the million dollar question was where would it set up. The actual surface low I think did not track that much closer to the coast from what the guidance had, however the quicker phasing of the systems provided stronger lift to the northwest side and therefore the snow shield was able to get farther west.
