Regardless of popular belief lately with the NAM and all..... the Euro needs to trend wetter and colder towards the other guidance by 00z tomorrow or something's up. Guess it's on to the ensembles. Probably a good bet to use them right now.

I’m guessing the ensembles are going to look pretty bleak considering the op.

I really want to toss the Euro at this stage, but that’s a tough pill to swallow. Hopefully, we see more agreement tomorrow. We often do see precip further N/W than modeled with overrunning setups, so that gives me some some hope up in my neck of the woods.

I guess it’s NAM/GGEM/ICON vs. Euro/UKMET right now with the GFS straddling the middle somewhere, but taking a step towards the NAM/GGEM/ICON tonight. I kind of am okay with the UKMET being a southern outlier given its biases, but I’d rather not see the Euro so different.
 
It's not known as Dr. No for nothing

Now I'm remembering how the Euro kept saying no snow here the other week when the other models were hyped and boom it didn't snow

Every other piece of guidance has significant moisture getting North.. the Euro just kind of fizzles. It's making me really start to wonder if it's going to come in colder on subsequent runs here soon (maybe the EPS) and try to throw an old solution out again. I have no idea.. I don't think the deep South will see another 10 inch + type of op run.. but somethings up. Maybe I'm wishcasting slightly.
 
I can’t believe we managed to reel this one in ... from a dumpster fire winter to a statewide (I’m talking about NC sorry everyone else who’s not effected) fairly significant snow storm brewing in just several days now
If you live south or east of Greensboro you’re going to be very disappointed I’m afraid.
 
I lived in High Point then and all we got was sleet, too. I think areas just north of Greensboro made out a lot better, though.

Yes...pretty sure I got about 5-6" of snow just north of downtown Kernersville, but the southside of Kernersville had much less.
 
Not a single member that looks like the NAM. It would be an epic bust by the Euro it if all of a sudden flipped to something the NAM is showing. In my time following weather I don’t think I have ever seen it.

EPS has 8/51 over 2”. 1–2” max at best looks reasonable though.

The run-to-run swings on the EPS have been absurd with this storm, it's been anything but consistent w/ this storm the last few days.

Yeah, but kind of need the euro or uk to hop on board. Riding with the B team can’t be good. We are 60 hours from go time.

The UK did shift NW at 0z by a good margin

The Euro has been extremely late to the party w/ the 2 winter events we've seen this year, I'm personally not too worried yet, especially since it agrees w/ the SREF, which is usually dead wrong at this stage in the game.
 
My goodness, the 06z NAM is mouth watering. From going to bed heartbroken by the Euro to seeing that first thing in the morning was quite the swing of emotions.
 
06z gfs tried hard to show a big storm at the start of March but looks to have just missed. Almost looks like a weaker/warmer version of 1993 but it will be gone by 12z. Still fun to look at.BB50DFD1-A847-4A21-918E-E37F5FFC2BA2.png

I no longer feel concerned by the euro being on the dry end of guidance. It's like the gfs coming north and the nam being too high on its qpf.

I'm kind of the same way but yet old habits die hard, NAM sucks and ride the euro..... Recent events tell us otherwise however. Still feeling pretty good about being North Northwest of the jackpot zone

While it's trending better for Carolina folks, it's getting worse for GA. I think it's going to be just too warm for snow at this point outside the mountains.

Yeah idk what happened with the new euro upgrade but the op hates precipitation it was way too dry all summer and its been in the lower 25% of the mean most of the winter. Rarely is it ever equal to the mean or in the top 50%

Yeah all of these upgrades have made us rethink the model biases and is confusing the crap out of me. haha

I was wondering how it has done with all the precip we have had since November. Doesn't sound like it has done good at all. Makes me feel better about it being out to lunch this time. I wonder how the NAM has compared with the getting the amount of precip right.
 
Last 4 runs of the EPS....looks like ensemble spread is shrinking. Was probably the worst EPS run member wise in a couple of days.

Huge red flags here. NWS at morehead city putting tons of eggs in the euro basket.

Today`s forecast leans toward the
ECMWF for a couple of reasons:

1.) The deterministic ECMWF and the EPS (Euro ensembles) are in
strong agreement, with the ECMWF being the most stable solution
the past few runs. The EPS probability of 1" of snow or greater
has been around 45-50% for the last few runs.

2.) The GFS ensembles average a bit lower than their
deterministic counterpart, and in fact are close to the ECMWF
and its members.

Have put snowfall accumulations in the grids, although even then
this is under the ECMWF solution due to expected warm surface
temperatures which should initially melt the snow (apart from
grassy surfaces and higher elevations) and the fact that coastal
winter storms like this generally feature SLRs well below 10:1.
For now, show generally under an inch for interior zones with
lower amounts towards the coast. It should be emphasized this
forecast is fluid and will be closely monitored, but at this
time it does not appear to be a high-impact event.
 
I haven't checked any soundings or maps yet, but if the NAM has a warm nose, then you can almost take that to the bank every time. Wouldn't be surprised to see that start to get established and trend stronger, which sucks.
Yea it sucks we’ve seen this a million times, and we have all day tomorrow to watch it jump further.
nam has a warm nose from hr 50-60 for clt while much of the precip moves through, and it even gets stronger from hr 54 or so on. this looks to be a sleet storm most likely for charlotte with token flakes on the back end. nam showing a warm nose like this and you can take it to the bank.

yep hard to ignore the writing on the wall it’ll jump north a few more times before Thursday if you’re on the edge of the snow line now you’ll be lucky to see sleet come verification.
 
if you think this doesn't end up a sleet storm for most of the board you haven't been tracking storms in this area long. we have seen this before many, many times.
 
I’m very thankful I was able to get my almost 4in last weekend. Hope you NC guys get some which looks like a lock at this point. I feel bad for the SC guys y’all can’t catch a break.
