Philly Winter Weather Update

The arctic airmass that will be moving in late Thursday has been well-advertised.

The models continue to hint at the possibility of some snow in the Sunday to Monday timeframe.  While the GFS has been unimpressive regarding cyclogenesis, the Navy NAVGEM and the Canadian models show low pressure developing along the frontal boundary. Still not great models consensus, but I’ve been watching this possibility for almost a week.  Stay tuned.
