I thought it was going to be better too. But classic DC split. We really needed a dominant stj wave to come along. If it’s all NS we’re fighting an uphill battle.

lol

Should of been already but it keeps getting pushed back due to delays in developing its replacement

It really has helped since I stopped paying any attention to them. They are just as likely to go off on a tangent even at 12 hours as get anything right. They just add confusion. We will all be better off when ncep stops running them soon!

Man stop It with those Atari maps. If you’re going to post depth maps fine but at least find one with PS2 level graphics.

My gut

Even that run was kinda meh. I went and looked at the individual members from the last few ensembles. I noticed something. The handful of members with a big 10”+ hit for DC there is a theme where it seems they run the NS wave way out ahead and wash it out then a stj wave develops behind that wave and phase with the trailing energy as the tail of the trough rotates down. Maybe the truth is there is no path with that NS SW we’re keying on now. If we want a big storm we need that to get out of the way so the energy rounding the tail of the trough can phase with thr stj? Dunno just an observation

Yea. And part of that is cyclical. But it’s also being exasperated by a northern stream that’s more active and shifted north which are both related to warming and a result of the expanding Hadley cell circulation in the pacific.

@Terpeast @WxUSAF @MillvilleWxI’ve noticed the last 24 hours the runs that are more suppressive with the TPV get the NS track we need but the wave ends up more suppressed with almost no STJ interaction. The less suppressive runs have a bigger storm but the NS wave comes across further north and so it’s mostly a Philly northeast storm. So what’s the path for us? What do we root for? My gut says more suppressive flow combined with stronger SW. But those runs seem to have less STJ and so it’s not much better.

could have been a better run if it had the same stj interaction as the last few. But it lost that completely and that offset what were some improvements in the NS piece.

NJ gets some inv trough action then the coastal gets going just in time to scrape cape cod.

Nope. NS SW came across as a better latitude for us but the whole thing was more suppressed. No stj interaction and the coastal took too long to get going. It’s not a good run for anyone. Light snow across MD and NJ.

There seems to be less stj interaction though. Don’t love that. But the NS SW was a bit south. I do like that. Next frames will determine.

It needs to amp up quick but everything’s coming in further south this run. So if it can crank at all it could be good.

It was a slight improvement I think

Keep talking dirty

Sounds like they’re having a hard time coming up with a quality system. Oh well.

The euro and icon are kinda in between with a wider more uniform distribution from the initial frontal banding because it shifts north then no real coastal enhancement. That would be acceptable.

It’s best to ignore the NAM. Actually the totals further south seem safer. It’s all from the initial band. Further north it’s a combo of getting fringed by wave 1 and 2. That’s the kinda stuff that’s risky. NW of 95 has more upside but also more bust potential is the initial band sets up south like non NAM guidance and then the coastal doesn’t get going in time. Would leave places NW dry.

Anyone know what that RRFS experimental thing is? Hopefully is sucks because it’s the only thing that has looked consistently awful for our area.

I meant real snow. That’s like 50” of NAM snow

Just count the mm as inches

Why aren’t there more examples of those patterns leading to 30”+ winters here than?

Why in the Philly thread dead?

Yea I think so. A few days out models had some 20” runs for DC. Then it became more NS dominant. Guidance is picking up on that now instead of teasing us with some early stj dominant solutions.
