Potential Snow 11/27 - 11/28


NEG NAO

Recommended Posts

this is a rough map i put together real quickly...ive barely looked into this but i took the nam's heaviest precip axis into mind (while cutting those totals way back of course)....not bad considering I gave it virtually no chance for the coastal plain in this setup a week ago

Didn't realize the fish had lawns. Other than that, looks like a decent map at this juncture. I'm waiting until 00z to make a call on this nail biter. May be a situation where folks outside of the deform band get a slushy coating-0.5" and in the strongest vv's you get 3-4". Tight gradients and elevation dependent.

Got down to 36 last nite in Colts neck I was on a west wind , Down to 33 already on a N wind and thats making a huge difference outside the city tonight .

I think the clouds played a big role last night. NYC area was socked in much of the night, areas further south were clear til late.

FYI, his profile says: Middletown, NY

Down to 30.9 in Muttontown now, great radiational cooling night for sure.

IS that you on weather underground muttontown? You are always the coolest spot in nassau by far, i am the albertson, station, down to 34/21

Think a lot of places to my west are really goin to start in the hole with this one .

Jutst wondering , do you put NEPA and West central NJ under a WSW with temps close to 30 in the AM

with .50 - .75 qpf a real possibility ? .

This event could end up like Nov. 30, 2000 or Nov. 27th 2002...A little rain ending as snow...Those were night time events...Another analog storm could be Nov. 20th 1955...1" of wet snow and some rain mixed in...That was a daylight event...

Eh, sun angles equivalent to early to mid January. This will be more intensity based IMO. (Sure elevation helps too)

No. Advisory. Precip doesn't get going until daybreak and temps will likely increase through the night (albeit to 32 or so) as clouds enter the area. Guys, an inch or two for WNJ is not a big deal. The Poconos will have a better BL, but the heaviest precip looks to miss them just to the south. Again, with such marginal temps and time of day, I just don't see this as being a problem.

How many years have you been forecasting for N. Jersey? <serious question>

I'm starting to believe 1-4" might actually happen in the city. NAM finally cooled off the surface enough so its believably some sticking snow at KNYC. Ratios will still stink, probably 5:1, so the 0.70" the NAM spits out comes down to 3.5", then subtract some more for the known NAM excessive QPF bias. Not sold on it yet, want to see the GFS pick up on it to some extent.

The NAM and RGEM both have this band of moderate to heavy snow sitting over Southeast PA for a few hours and then moving progressively northeast through NJ and now, this run, towards NYC before it weakens a bit. I think areas that get under this area of enhanced lift and banding could see 2-4" and I woudln't be surprised if someone in SE PA or Western NJ saw 5-6" should this band develop as the NAM suggests.

You can also see the NAM picking up on the dynamic cooling under this band with temps 3-6 degrees lower than surrounding areas.
