Ggem says no, but closer than 0z. Loses mid level temps before the WAA precip arrives. Gfs a smidge colder, so it’s frozen precip. Ggem then takes the ULL through PA so we get some backside flurries/rain showers.
I think there’s going to be some bizarre divergence this winter between the gfs and GEFS because of the dynamical core differences. We’ve already seen that a bit and we’re continuing to see it in the strat. I’m really not sure how to interpret any differences either.
Sober reminder here that everyone should have very low/no expectations for this storm. It’s way too goofy of a setup. Plus the gfs long range cold bias.
More than a southward trend on the path of the ULL, the GFS has clearly trended to a weaker one. That reduces the ridging out ahead of it and makes for a bit less warm push aloft.
I agree with @Bob Chill that hoping for a snowy deform band like the GFS is currently showing for the NYC-BOS corridor is tilting at windmills.
I’m not sure which of the WAA overrunning or the ULL passage is most likely to offer snow chances. Both are likely to be fairly narrow areas and the airmass is marginal in both cases. Today’s euro probably showed max upside.
P.S. the track shifting a bit south certainly helps the WAA chances.
Euro gets it done just by slightly strengthening that high to our north and also starting the coastal transfer earlier to our south. Like the gfs, euro takes the ULL basically overhead and takes the precip with it through central VA.
The trend for the LR to look far from catastrophic continues on the 12z GEFS. The super positive AO is gone, with it probably neutral or weakly positive by the 3rd or so. Still looks to me like there’s a lot of spread after the 3rd or 4th.
