Just observing what is going on right now in my simpleton mind is reason enough to conclude this is a whole lot of nothing here. There is no Arctic airmass. We had clear skies and dews around 20, and DCA barely sniffed freezing last night- busted on the forecast low of 29. High today supposed to be 42, probably hit 45 give or take a degree. The point is there might be a H in Canada, but it not a "Canadian" high. Everyone talks about CAD being under modeled and slow to retreat. Sure- when it is COLD air damning, not COOl air damning. We basically are entering the storm with a seasonal to perhaps slightly below normal airmass and a ton of air from very mild waters ready to flood in. So sure, with low dews we may wet bulb at the start so we see flakes flying at the outset, but this will likely be a very quick changeover and a lot of wet roads. Anything on the backside will be luck. Just observations from nearly half a century in the immediate metro.
