12z Euro is closer to the coast on this run but not close enough. Light snow event on this run for NYC. Boston and Eastern SNE get more snow.

 

 

I think this trough will sharpen even more and we will get a decent hit of snow from NJ on North!!!

The norlun is in a real favorable spot for us on this run. These bands usually are hard to forecast, but lead to great surprises.

Still plenty of time to trend, def a interesting set-up

 

The vort dug more on this run and the low was closer to the coast.

Will not take much to bump up the precip totals.

Vista maps are deceiving. Soundings are wetter for NYC.:

 

Total precip:

 

NYC: .19" (surface below 32 most of the storm. Hits 33 near the end)

JFK: .22" (surface below 32 most of the storm. Hits 34 near the end)

ISP: .17" (surface 33-35 degrees the whole storm)

FOK: .17" (surface 33-36 degrees the whole storm)

BDR: .10" (surface below 32 the whole storm)

BOS: .14" (surface hits 33 at it's warmest)

WU maps show inverted trough with heavier banding over NYC

If the trend of the 12Z runs to get that coastal going quicker and that deep are accurate we won't have to worry about temps anyway, only on the NAM's solution and sure enough again look where the NAM/NOGAPS are in this situation, exactly where you'd expect them west and east, I was pounding the drum prior to 1/25 that something smelled funny at 90 hours when those models were not in the right places respectively.

Indeed you were.  Nailed that --- so let's see if you go 2 for 2 on this!
