Big time -AO on 0z GFS ensembles hr96-300. probably <-2 std.
180-192hr to me looks like big ice somewhere as there is arctic blocking/ridging, and the PV underneath of it near the Hudson Bay and SE Canada, then a ridge riding over it in the Mid-Atlantic from south-based+NAO. -AO's are our best index pattern for snow though, so it's possible it's snow north of DC/Balt in the normal climate zones and ice south.. still way far ways out.. it can go either way but with a <-2 AO less chance it's rain, imo. See if that part holds.
