Not too many changes with respect to the overrunning wave of snow Tuesday into Wednesday. Focus in the Mid Atlantic region will be over Virginia and Maryland, with strong high pressure over New England. The exact position of the snowfall axis is still moving around a lot between model runs.
Latest model guidance spread is still high with respect to the energy dropping into the southwest US, but that is to be expected. The NAM is currently the slowest to eject the energy eastward. The latest model trends are faster with the ejection. The ECMWF has trended to openning the closed H5 low, with the GFS now on that train of thought as well. This then brings all the energy eastward by the end of the week, leading to a strong storm system moving close to the region on Thursday. As it stands, I believe the potential exists for a moderate to heavy snow storm for much of SNE. There is a general trend north (largely associated with quickening trend), so ultimately there should be ptype issues across coastal sections, with heaviest accumulations centered across interior SNE.
