For some locations, this is the difference between 3 inches or 10, 6 inches or 12, 12 inches or 18, etc. The 18z NAM was an absolute whopper with blitzing snow, and it happens to be in between the GFS/HRRR.

Meanwhile, an impressive upper level jet streak has developed over New England. Between this feature and the HP, I feel pretty good about the low taking a more eastern track. I think the GFS is way off, but time will tell.

I just looked at 3km nam and it barely gives most of the area 6 inches, am i missing something? Ok why is 12km so different? I thought these were the same model just different resolutions?

Look at that heavy heavy yellow 30-35dbz band of just puking snow

I wonder if that band will make it into central and northern nj

steady snow, temp dropped to 24! Keep it down, this thing is go be great, I feel it! Only place not sticking is where they put down brine. But it will once it gets heavier. Everything else is nearly coated.

by **billg315** Wed Dec 16, 2020 4:53 pm

Definitely in a steady moderate snow now. And the wind is starting to whip it around out there. Everything is now snow-covered, even surfaces that were pre-treated but not heavily traveled. And we have dropped to 25*.

Just made it home. Slow go on the roads

The rain/snow line has gotten beaten back much further east. Tom's river is almost in snow now.

I don't believe a more westward track is in the cards for this one.

Just a dusting here in Hunterdon county. Letting Go Pro do the measuring.

Longtime viewer from Roebling NJ (just south of Trenton). Been holding steady at 30* about to get into that heavy band. A little less than an inch on the ground.

It is definitely moving northward now. But will it stall again?

You little Gen x, if the city ain't flipping you ain't either. Always, watch you get a blizzard warning overnight!!

by **billg315** Wed Dec 16, 2020 5:07 pm

Man the video from the Reading-Allentown area now is very impressive. I know CP hates the term, but puking snow in that region. That band extends southeast into Burlington Co NJ so it should be moving north/northeast into Central NJ soon.

She's developing much further SE and IMO will push further to the east. Thermals will be colder. Of course IMO.
