Latest take from Mount Holly-
Models continue to trend more suppressed and weaker with the southern-stream trough, owing to continued confluent midlevel flow from amplifying troughing in far eastern Canada. As a result, the QPF shield has shifted so that the maximum axis is generally in the southern half of the CWA Wednesday night and Thursday. Large-scale lift will be somewhat weak, so snow rates should be light to modest at best. Nevertheless, temperatures will be sufficiently cold for snow in virtually all of the CWA. By Thursday, current snow totals of 1-3 inches are fairly widespread south of I-78, with the highest amounts generally south of I-76. A second round of snow may occur as a stronger vort max approaches the East Coast on Thursday night and Friday. The NAM has trended well south with this, mostly keeping QPF out of the CWA. The ECMWF has trended this way as well, though to a much less extreme extent. The GFS and CMC, meanwhile, are farther north and provide another round of light snow to much of the area. By Friday, widespread totals of 2 to 5 inches are possible across the area, with highest confidence for the southern half of the CWA. The model trends continue colder for this period as well, given the lingering influence of the surface high to our north. This suggests the event will be primarily snow for the CWA, with any mixing likely to occur in far southern Delmarva and southeast New Jersey. Forecast temperatures were kept lower than consensus, and mainly weighted toward colder raw guidance, which tends to perform best in these regimes. Though the snow will generally be light, the sufficient cold and longer potential duration suggest meaningful impacts appear likely for our forecast area.
