More models nailed it than we realized. It was just hard to believe this time of year with ESE flow in the mid levels and the surface supposedly going east as well that we’d see anything at best better than a ton of sleet. I wasn’t so much surprised by the fact the surface winds stayed NE as the last 5 years or so we’ve seen highs seemingly able to anchor better CAD into the metro than we ever did before but how the mid levels didn’t get overwhelmed I’ll never know. The lesson might be that SE flow in the mid levels doesn’t get underdone by models as severely as SW flow does. Most showed a near isothermal layer or -1 and I thought that would verify +1-2. Another interesting factor yesterday was how most stations went 080-090 as the snow moved in and then went right back to 030-050 soon after. That almost seemed to be some sort of frontogenetical inflow into the leading edge of the snow
I hate to say it, but I didn't pay one lick of attention to this until yesterday when the WWA was posted circa noon. Being from Baltimore, I've never seen that much snow before December 1 in my life. Not even close. I even posted on Facebook that this would be a 'very unserious event' just before that advisory went up -- without having done my due diligence -- precisely because, well, mid-Nov. and climo. And it wasn't until around 3-4PM, with temps DROPPING to 28-29, that I truly began to question whether that CAD would get eroded before rush hour. It absolutely dumped up here in Harlem until around 8-9PM. I didn't measure, and not sure what was 'reported' at Central Park, but we easily got 5-6 inches up here.
