Heck, we could see snow into Wednesday. 

That's the question right now. No doubt, we are in for crippling snows but does it shut off tomorrow afternoon or goes past 0z Wed.

If the GFS holds serve.....its really going to gain some street creds in the Met world.

I may have to stop referring to it as the GooFuS.

We will know shortly.  Loving the trends so far, as I dare say, I've done this long enough to know that the tick East was incoming.

I dare say we just got NAM'd by all 3 birds....

my best math....;)

 

2.2" at a paltry 6:1 ratio still gives 13.42".....and thats me being conservative.  

If we achieve a mean ratio of 10:1...thats 22.22"

I am going to set up a yard stick after work tonight. Also am thinking about a location for a webcam.... We are in the jackpot zone now.

not even 5 minutes ago i told a co-worker i'd bet him lunch that the State announces they're going t close tomorrow. And maybe the Gov. will initiate a State of Emergency before lunch time.

Looking at some of the WSW statements to our SE. If sleet is just a little farther NW than progged, there will be a huge sleety bust in the I-95 corridor. Eric Horst just tweeted me about large bombing systems having the transition line farther NW than modeled. He'd be the guy to know!

That's what I was saying! And he's the one I was referring to!

IF I did this right, just of 37 inches At KAVP. WOW...

They are, and while they are not on last year's levels, the precip max shield aligns real close to last year's blizzard with a Blue Mountain jackpot.

The fact that the NAM and Euro are even spitting out numbers in the 20"+ range this close to start for the LSV after lasts mauling boggles my mind.

And it's always nice when the numbers are increasing in the final hours leading into the storm...

Yes it is.  If we can keep the big guns aimed at 12z as they were at 0z, I'm going to sit back a bit and let the flakes fall where they may.

Oh...I'll still be here but I'm just going to try and enjoy the storm and worry less about what happens.  This has been most enjoyable, but I've really been a useless putz for the last few days.

I have a feeling that somebody in this forum sees record snowfall, and somebody in this forum gets really, really screwed.

[Superstorm]

RGEM is looking good.

RGEM at 24 comes in a tick colder and 850's never get beyond Southern Lanco. at 27 they are crashing for the coast.  Its fantastic look.

"warmest" panel.  700's are fine.

12z NAM surface low slightly east at HR 18 (32 & 12k versions), sleet/snow line pushed about 25 miles at that hour. 

 25 miles east for the win. Considering I am in Lititz I like that. Let us keep it in Chester if all possible. But Nut was right good snows are near that line just not to near it.

Yessir....that we are....

QPF is JUICY

[Itstrainingtime]

One thing I've been watching is how far southwest of us good snows extend. I think it was the 0z NAM that the 6" line was all the way up into southern York and Lancaster counties. That has moved back farther southwest into MD, which is a good trend as well. 

[pasnownut]

Shoudl also add that in panels of interest, at 33 SLP is basically on top of 6z position.

approx 50 miles of Atl. City.

Yupp..the southern low has trended stronger and sharper, thus putting good banding down there too.

CTP updated the warnings and is going bigly in snow totals.

 

...WINTER STORM WARNING REMAINS IN EFFECT FROM 8 PM THIS EVENING
TO 10 PM EDT TUESDAY...

* LOCATIONS...The Central and Northeastern Mountains and the
  Susquehanna Valley.

* HAZARD TYPES...Heavy snow.

* SNOW ACCUMULATIONS...12 to 18 inches. Higher amounts of 18 to 24
  inches are possible on the ridges of the Poconos and in the
  Middle Susquehanna Valley.

* TIMING...Snow will move into far southern and far northern
  Pennsylvania around or after sunset. The snow will rapidly
  overspread all of central Pennsylvania by midnight. The heaviest
  snow will fall from midnight through Tuesday afternoon,
  especially right during the morning commute. The morning commute
  on Tuesday will be extremely difficult. Additional, lighter snow
  is expected to linger into Tuesday evening.

* IMPACTS...Travel will become difficult to nearly impossible late
  tonight through Tuesday afternoon, with snow covered, slippery
  roads, and poor visibilities. Avoid travel, if at all possible.


* WINDS...Southeast at 5 to 10 mph turning quickly to the
  northeast and increasing to 10 to 15 mph. The wind will be
  faster in the lower Susquehanna Valley, where speeds will be
  more like 10 to 20 mph with gusts of 25 to 30 mph at times.

* TEMPERATURES...In the upper 20s to lower 30s.

yep, that is a good thing right there

[pasnownut]

GFS at 24 and 30 is a tick NW and evolution is basically identical to 6z.  Its unwaivering.

[Jns2183]

Yupp..the southern low has trended stronger and sharper, thus putting good banding down there too. 

Good luck with forecasting that snow/sleet line along with the mesoscale banding and associated subsidence between bands!
