Welcome home.  Growing consensus slowing this down 

I was amazed at how much snow is piled up around Logan including deep pack between the runways and taxiways.  This is a heckuva winter despite a lot of whining by some…at least the way I see it.

00z HREF. Sum the two to get your total:

 

snowfall_024h_mean.ne.f02400.png

snowfall_024h_mean.ne.f04800 (1).png

It composes of the current (no lag like the NBM) cycles of the HRRR, WRF-NSSL, WRF-ARW, FV3, and NAM 3km models (00z cycles)... So only the high-resolution stuff.

Wolfie pulled it off in the end.

Yea, never had a blizzard with this much antecedent pack and so fresh on the heels of another storm with zero melting...

Usually bare ground or just crust left. This is going to be awesome. Even if we end with 10 to 12 here the drifts will be epic

What a winter for BDR and HVN. First time I've ever heard upton mention 3 foot totals

On the higher end, the NBM (01Z) supports 23 to 30 inches across the area, due to a bit more QPF and the aforementioned higher ratios. Its 90th percentile supports close to 3 ft across much of the area. The NAMNest is also on the higher end with 2 to 3 inches of liquid equivalent. This is likely due to its more westward track. The 06Z HRRR which is similar in its track is very much in line with the current forecast. However, a reasonable worst case could put totals up to 3 ft. While the highest totals are expected along the coast, heavier bands of snow (strong frontogenetic forcing) can rotate inland and usually on the cold air side of the best forcing. These bands are ofter a challenge to forecast and often leads to localized higher amounts.
