The h5 look on the GEFS for the 8th is pretty much what we want to see for a MA winter storm. A -EPO with a southward displaced TPV, -NAO with lower heights off the Canadian Maritimes. Cold enough at the surface. The surface pressure depiction isnt ideal but this is still pretty far out. As depicted there is energy digging into the SW in conjunction with plenty of NS vorticity associated with the flow between the EPO ridge and the TPV. The timing and interaction between these shortwaves will determine ultimate outcomes, and tracking it will be nerve racking lol.
