I think we are going to see a significant winter storm over a good portion of the forum area. I could be wrong. But that GFS run cranks. It definitely has some pieces the E TN peeps won't want, but the CMC is an entirely different solution. The GFS is basically a dry slot in a comma head. It is not so much that it falls apart as we get dry slotted. The dry slot bullseye is going to move around some. But the 12z suite brings frozen to most counties in our forum area. I really, really don't want what the CMC is dishing. However, that is a very plausible outcome, and fits climatology.

Long range deterministic runs and their ensembles are honking for an overrunning event around the 20th. That probably would impact western areas. I have seen that setup many times, and it is there plain as day on modeling.

They took out the weaker solutions?

The 18z Euro sure looked a lot like the 18z GFS. Didn’t quite head up the coast but trending that way.

Clean phase instead of the dirty phase from the past few days. That low in the Lakes got entrained. Spins right down into the developing storm. And we aren't far off with the system behind it.

The 18z GEFS has it.

This is gonna be a monster run with the small systems which follow the bl......bigger storm.

The comma would have blizzard conditions in our mountains on that run. 40mph gusts with moderate to heavy snow falling along the TN/NC line. TRI would have 25-30mph gusts under the comma head.

All I can say.....I have no idea if we see anything close to that(probably not in the NE). But if that is real, learn everything you can when tracking it. We don't get those very often. That would go in a book some day. If anything, just enjoy that run.

Can anyone get a Kuchara map for just that storm including the upslope after, ~ roughly Jan 11-13?

42" in 24 hours. (Kuchera)

Somebody up there just got four feet on that run. That was a blizzard run. edit: 3' for that storm. I forgot to take out the current storm.

The guys in the MA forum might need some smelling salts after that run.

That has 78mph sustained winds at 156.

That gets to 966 off NYC. That is a blizzard for them.

If that phases misses, there is one which is only about 24-36 hours right behind it.

The low diving into the backside of that storm caused the system to back the southwest flow just a bit. That caused the southwest flow in front. The "low in the lakes" setup yields more snow, but a less powerful system. The only issue with that setup is that the slp could trend northwest over several runs. That is a really big storm. It deepens rapidly. That is a boomer. But all-in-all, we take that run in spades.

Looks like there is something right behind it.

@Daniel Boone, that 18z GFS run a 95-96 redux?

That is a Panhandle to Hatteras track. E TN usually does just fine with those. The southwest flow in front of the system is a problem. However, if it turns the corner cold will slam into the northwest quadrant of that storm.

The thing with big storms that I often see, we almost always deal with some energy going up the eastern valley when there is an inland runner. IF (stress IF) that is a really solution, that would be much, much bigger IMHO. That is a boomer. There should be no low over the Lakes. It came right on down the Plains. If it does that, we are possibly in business. Even though I get downsloped on that run, I take that 10/10 times in my local. Foothills folks would likely have a different answe

I wasn't paying attention. When watching at 3 hour increments, I just assume it is going faster than I think it is!!! That is a really, really good track. I look more at track at this range.

MRX mentioned southwest flow in front of the storm. Looks like it is going to gain some latitude. Let's see how much. Just another iteration of the scenario. That is gonna be an inland runner. IF it actually takes that track, it should be significantly bigger. Good, good run.

So, the low in the Lakes is diving into the back of the low from the Southwest. If it can actually pull that off during future runs....very big storm.

Should be good.....
