I don't understand this snowfall map from Mt. Holly. If this were to verify, the entire Warning area from Trenton on northward and west of 287 should be downgraded to advisories. I think that area easily sees 7-10" even without the heaviest banding staying just to the east.

:unsure: It has all of those areas getting at least 6 inches, which is the threshold for warning criteria.

NAM/ARW/RUC/RR/HRRR are backing off (wrt track/precip) like it's no one's business and I get the feeling on the 0z runs right before the storm begins to hit they're gonna back off a little more with the precip. 5-6" for Philly thought is still a solid storm..

I love that name! Pretty much sums up weather forecasting...

I am sure to check out the next set of model runs and how they are handling the phasing, and the placement, and certainly look at the meso models, but at this point, it is really a nowcast. With that kind of deepening being progged, this storm can certainly be pulled even closer to the coast than any model is predicting, and looking at the strength of the system over the Ohio Valley, it will be interesting to see the influence in track of the coastal low as it intensifies, We have seen this before, we will see it again!

If you don't have a clue what your looking at please don't comment. For starters, HPC disregarded the GFS and NAM due to initialization errors with the placement of the low being much further west than depicted on the GFS and stronger than depicted by both. Second, some of the high res models have gone absolutly insane with precip totals. Philadelphia was never in line to be jackpoted unless you were banking on the 06z NAM verifying. Still think PHI gets about the same as they did with the boxing day event, especially just east.

It has some areas forecasted to get less than 6" in the warned area and it has other areas barely making the threashold. I guess 6" would still be a warning criteria event but it certainly wouldn't feel like one.

would be nice to get a pro met opinion on all this!!

Read the AFD from Mt. Holly. Jeez

10:45AM update:

.NEAR TERM /THROUGH TONIGHT/...

-- Changed Discussion --THE SURFACE LOW PRESSURE SYSTEM OFF THE SOUTHERN NORTH CAROLINA

CONTINUES TO BE TUCKED IN TOWARD THE WESTERN EDGE OF THE MODEL

SOLUTIONS. ITS INTENSITY IS PRETTY MUCH ON TRACK.

OFF THE MODEL INITIALIZATION AT 12Z, THE GFS APPEARS TOO FLAT WITH

THE SERN TROF AT 500MB AND A FARTHER OFFSHORE WHILE INTERNALLY

LOGICAL, MAY BE TOO EAST. THE WALLOPS 1C WARMER TEMPS AT 850MB

ARE NOT EXTENDING THAT FAR INLAND AS APG AND IAD 850MB TEMPS ARE

AT OR BELOW -4C AND MODEL INITIALIZATION IS TOO WARM THERE. SO NO BIG

PTYPE CHANGES WITH THIS UPDATE.

You come off quite condescending. :thumbsdown:

I never said anything about being in the jackpot or the 6z NAM. I was point out that the hi-res/nowcast models are cutting off the precip and or pushing the track a bit east, even the ones that haven't been disregarded (RUC, RR, HRRR).

But you would be incorrect in saying so. The shift has been to have a track tucked in closer to the coast.

MM5 and RGEM both looked pretty good to me...i feel like the trends are positive, not negative.

Mt. Holly may get some egg on their face, I really appreciate all the work they do and I know they work hard, but just like WE get burnt on model hugging, so too will THEY.

WHAT ARE YOU TALKING ABOUT!?

They are stating that the initialation is wrong. How is that model hugging? It's fact!

Nobody in THIS thread cares about qpf totals from Bergen County on NE. Go back to the NYC thread where you belong. <BR><BR>The other poster is correct in that all of the modeling coming in over the past few hours...even the ST hi-res stuff has backed off the qpf for PHL and the surrounding area. The low tracks seem to be creeping westward with more intense lows but this seems to be tightening up the qpf gradient on the western periphery....we to the west would probably make out better with a less intense low so the precip field spreads out more.<BR><BR>

<BR>Read the NYC forum and you will see all of the high res talk. The QPF totals espeically from Bergen County on NE are just insane.<BR>

The point of my post was that the models are coming in better than before unlike the other poster that indicated that the trends were negative. I'm in Morris County which last time I checked was in Mt Holly. If NE Jersey gets crushed, then the Mt. Holly CWA should do quite well. That's my point! :axe:
