It's difficult to resolve. Basically models have to nail where this secondary cyclogenesis occurs and then the complex interactions of the s/w rounding the trough will help dictate where it goes. At the same time as the midlevels start to close off and deform to the NW, the snow develops and spreads in. That's why guidance is all over the place. We have some favorable things going like good 850 inflow and WAA, mid levels closing off etc. But it may be a tight cutoff from the gentle 2-3" stuff that falls over hours, vs an uber band that will certainly be just offshore.
