Euro- wet frontal boundary, with back end flurry potential, followed by deep cold and suppression (snow down to FL panhandle). Basically the low runs out ahead of the HP, never allowing a wave to run along the boundary
GFS- a HP further east, and a stronger wave, mean the two duke it out. Ultimately the LP wins, cutting north, but not before a long duration frozen mess takes place, due to a stalled boundary.
Canadian - similar to the Euro, but perhaps a step towards the GFS
