The GEM makes sense when you look under the hood. SLP doesn’t really deepen until it’s passing NE of the area. WAA doesn’t take off until east as well, and 850’s are actually out of the west of a period of time. On the flip side, the GFS has good snows further south for a different reason. It has the SLP strengthening sooner, with more WAA sooner and further west. However, the further south track helps bring the good snows further south. .
