GFS at 102 hr....You can see the coastal starts to develop off the North Carolina coast

GFS at 120 hr...The coastal looks very good.

EURO

Canadian

All the models are showing a monster storm.....We will see how the models handle the track after the system moves through over the weekend.....But if I had the bet...I think this is going to be the storm most of us have been looking for. Think snow :thumbsup:

Overly optimistic here aren't we? Like the kid in a candy store or the night before Christmas waiting for Santa. ;-)

Actually I think the low slides up out of the G of M to SW GA then re-develops in the inverted trough due to the incredible CAD along the EC from New England to GA! That inverted trough will act as a pathway/highway for the low to move along.

Still waiting to see ensemble anomaly data come on board with anomalous 850 E and/or SE winds and PWATS too. So far they are not (though I didn't see any such data from 12z or later today). Even though they weren't doing so on the data that I did see, just based on pattern recognition with the HP over New England and the low along the ECUS there looks to be good Atlantic inflow for sure; maybe even a subtropical moisture feed from the Bahamas. Also the full-amplitude trough to the west extends to the G of M so there is some moisture transport from there too. This is going to be a juiced system.

Now this I would be happy with. It likely won't happen though.

I think you'd like the FIM and the UKMET (posted earlier). Here's the FIM:

It has been doing pretty well during the past few EC storms. I don't think once has it "weenied" us into thinking we were going to be hit.....and in reality (for most of C/W NY and S. Ontario) it's been right on the mark in that department.

thats interesting LEK....havent followed the FIM, i thought its had a NW bias, but i must be mixing it up with other developmental projects as per your notes this season of it being quite good.

good to hear.

The models are all in agreement that the NEUS will have a major snowstorm...They just differ on the track and timing. The GFS has the fastest solution; it also looks like it wants to keep the low off the coast for a few days...I don't know if I buy into that...We don't have the blocking in place we had a few weeks ago The Canadian is very aggressive with the storm...But, it has been overly aggressive with most of these coastal of late. The EURO is playing man in the middle... Like I said this morning, we will have to wait until the Clipper system moves through this weekend and see what the models have to say then...The High will be very important, because it will determine how much blocking there will be and the amount of cold air damming if any that will be in place.

The key word is "if" but you gotta love the possibility. Bring it!!!

I wonder about this so called warning flag thing but I am rooting it on!!!!!

I do not like that the models are delaying this storm. We went from a storm attacking a somewhat fresh, true arctic high over the NE, to a situation where the high is shifting off the coast and we are left with a progressively stale cold airmass that is gradually being eroded by a SE flow around the high. This also argues for an inland track up the coast. I still think we have a shot at the jackpot in ENY (especially N. of ALB) along with CNY, but with any further delay causing us to say congrats to Ottawa or Toronto :popcorn:

Suits me. The east coast has had its fair share this winter. Time to spread the love! :devilsmiley:

00Z GFS has gone from a Miller A to an Miller B and as you can see more or less out to sea

wf84.gif

wf138.gif

The Canadian is still going with a Miller A and track inland. This track would give Western PA , Western, Central, and Northern NY with a lot of snow.

The EURO is still in the middle. But, its solution is a lot more like the Canadian

The track of this H5 Low that is supported by the ECMWF and CMC is normally a sign of a very big East Coast storm. Whereas the GFS gives the NEUS next to nothing.

I think the GMS will bounce back to the west. to more closely mirror it's cousins. The reason I feel this way is the NAO is negative but it's more to the east than it has been. This allows for less upstream blocking. Therefore, the blocking being out of place will allow the storm to track more to the West.

The EURO and UKMET show a negativity tilted trough by Monday . We will just have to wait most likely until Sunday and see what the Model runs show. Hopefully by then we will have an Idea how the trough will set up and a better Idea how the H5 low will track.

The values in the upper right and left show the mean value

The Black line in the first panel show the observed NAO Index

The Red lines are the MRF ensemble members

The ensemble mean forecasts of the NAO index are obtained by averaging the 11 MRF ensemble members

The yellow shading shows the ensemble mean plus and minus one standard deviation among the ensemble members, while the upper and lower red lines show the range of the forecasted indices, respectively.

euro with its second consecutive huge run for ny state.....and in fact everyone get in on it, even ottawa.

takes a 975 low across long island and towards new brunswick...........does not veer off the coast and towards nova scotia as per usual this year!

copious qpf ny gets hammered.

the least is for WNY......buf about 0.3

roc approx 0.4

then amounts go way up sharply

1.75 syr

southern tier from I-81 to the New england border 2.00-2.50 qpf

nyc is actually about 2.75

alb around 2.00

gfl 1.75

ART approx 1.4

BTV SLK MSS 1.25-1.5

montreal 1.25-1.5

ottawa 1-1.25

the 00z euro sticks the main deformation band right through ny state....actually dryslots SNE it appears

storm is a bomb

Oh what i would do to lock this euro solution in right now. gfs seems to be on its own but who knows it may be seeing something the others aren't.

lol yeah its a pretty sick storm

hate to throw out analogs, but this is a biggie as per the 00z euro.

but the models are WAAAAAAAY all over the place.

we all here in this thread do deserve one storm that we can all revel in......this one's pretty close, nudge it 50 miles NW and i think everyone gets a lot of snow as per tonights euro.

yeah there is definitely wiggle room for it to come north and still keep us primarily snow here and definitely further north. If it come southeast from the euro depiction it would hurt west/central ny to southern quebec and help out the new england crowd. i think we're all due for a big one but anyways its nice to see this in the ALY AFD:
