Big Noreaster Rain/wind/wet snow thread 1/22-1/23

Yesterday the NAM was west when the gfs and euro were east on the coast.  Then it went east, and now it's back to west. I don't know if this means the low is sensitive to small changes or if it's just the NAM being the NAM.

GFS has been pretty consistent over its last three runs.

I think it moved very much toward the GFS and Euro in its last run.

All three (u,g,e) have what to me looks like a progression for the low that I don't remember ever seeing.  The low seems to transfer from west Tenn to the upstate of South Carolina, head due north, then transfer again around our latitude.  Perhaps I'm not seeing it correctly, but that low popping up out of nowhere in the upstate of SC is strange.

Maybe that's just the model spitting out solutions that don't make sense because the data it's seeing is incomplete or maybe a better word is flawed, today. It will settle on just one transfer soon, I would bet.

The suspense of uncertainty with colder or warmer rain is electric.

This is such a kick in the nuts. The anniversary of one of our best storms ever gives us a Nor'easter that's 33 & rain. I'd have just preferred a 60 degree blowtorch if it's not gonna snow. 

Hopefully people in the northern & western regions of the subforum can get a little something at least.

More like 50 and rain. Its always 50 lately. Lots of 50. Better than a torch though.

JI should remove the "wet snow" from the thread title. Likely will have to be in western NY or into Canada for that.

I bet Garrett County gets a few inches and parts of WV and southwest Pa will probably as well once 850's crash out that way .

Yeah there certainly could be some snow mixed in out that way Monday night, but based on current trends it would not be a big deal.

Where the hell do you get 33 and rain from....I dont get all the talk on this one. Other than it being an interesting cut off low that produces wind, coastal issues and decent rains. Ill get backlash for this, but you guys over analyze things way too much on this forum

Notable shift east in the gefs members...

At this point it is to late. One of the key things we needed to see was the primary track to our south to keep our region in a somewhat easterly flow. With the primary tracking so far north into west virginia we see a more southerly flow that destroys any hopes of keeping the temps to a somewhat manageable level until after the transfer.

The 33 & rain comment was tongue in cheek (hence the italics). I know it'll be 50 dude. I posted in the panic room how every day seems to be 50 and clouds/rain just like February '98.

This forum actually used to be funny but lately seems to be populated with uptight, humorless people.

 Though the CMC still shows some promise, albeit very slim, IMO it was just one very small step away from completely folding to the EPS and GEFS on its 00Z run. On the previous promising runs of all three models the one key feature was to bring the primary east of the mountains in the southeast before moving north and transferring off the coast.  I have to believe that this was induced by the tendency for somewhat lower pressures on the lee side of the mountainous terrain in the south east with a westerly flow. Though the influence of this feature is minimal I think it was enough to tip the balance in favor of bringing the primary into the coastal plain. Now for whatever reason (500's, lack of westerly flow, greater separation with the primary from that influence, a cow farting) that influence is no longer enough on the GEFS and EPS so now we see the primary stay on the western side of the mountains when it begins its turn north. The 00Z CMC illustrates this idea fairly well. The CMC initially follows with the other models by beginning to bring the primary northward on the western side of the mountains only to then make an awkward transfer back down across the mountains into western NC/SC and northern GA as it sees that influence. Is this possibly, yes, is it probable, probably not, especially when you have the GFS and EURO arguing against it. I would not be surprised that with the 12Z run we see this influence diminished enough that we see an almost total cave to the other models.

Just wait until New England kicks the **** out of Pittsburgh.  He'll really be fun then.

Im actually not a Steelers fan lol. I know the image is tough to see but that pic is when Big Ben got his nose broke by the Ravens. I just thought it was funny. Ravens fan here, but that could still explain the bitterness

Ah, OK.

Vikes fan here so by all rights I should be homicidal.

Keeps ticking S and E but it's all too little too late for our respective areas. Nice storm tho. 

CMC is still trying. Jumps the primary over the mountains into the coastal plains farther south. Thus we aren't seeing the southerly flow that is completely wrecking the temps like the more northern solution of the GFS and the Euro. Probably a moot point anyway after casually looking at how deep the warm layer is running up from the surface. Even if the 850's were to cooperate I don't think we could overcome that except for the extreme higher elevations.

NAM is a monster. Much deeper slp this run. 982@36 hrs vs 989/990 last run same time. Again, nice storm if you're into this hobby for more than just snow.

What interests me is the fact that at day 13 all 3 models were advertising a fairly significant storm for this time period with a very similar evolution as we are seeing now. Except for losing it for a couple days in the extended they have been pretty steadfast on running a low up the mountains with a transfer over to the coast in the general MD/DE coastal region. IF this general idea verifies it will be a major accomplishment for all 3 models and yet many will not be aware of it because it wasn't a snowstorm.
