The Feb 10-12 storm threat, real or imagined?

lol at what this winter has done to the forum. 11:30EST, the 00z GFS is rolling out with a legit snow storm for the 11th, and there are all of 3 people in this thread

A moderate Pete to CNE snowstorm on the GFS and you're hoping for a bunch of posts? In a ideal world there would be little to no posts about 156 hour op gfs, anyway lol.

I thought we should all give anyway, Sam? You've been trolling for the last week or more about how this winter is over.

I know long range guys have been banging the drum on that period..but that has a "threading the needle" look. Too much PV and it's out to sea...too little and it shoots right up the coastal plain.

It might end up being a needle thread type storm...but until we really get a better handle on how rounded the PV is or not, then we won't really know...if the PV gets more stretched out like it has been slowly doing on recent runs, then it will start giving more margin for error.

Come on, you know any other winter, we would have a string of posts on the GFS storm. Not saying they're justified, but that's what we'd get. At the very least, there would be a crowd in the thread. There were literally three people lol.

But it's true. It's all futile anyway. People have finally caught on. I'm glad.

Yeah I think that's what HM was mentioning...he thinks the threat is real...but seemed to have some concern about high tight and fast the PV will be since the strat-vortex is right overtop of the mid-level one.

what's true?

People just haven't been posting as much since they are emotionally drained and have given up...it's not because they've learned that the 7 day op runs are mostly garbage.

Definitely agree it's a classic threading the needle look. Preferably, the weak s/w that swings through on Thursday is more amplified and slower and might help to simulate some degree of blocking downstream. Otherwise we have deep layer S/SW flow up the east coast and across Nova Scotia and Newfoundland with a slight shift one way or another yielding drastically different results.

Also preferably in that situation, we see more of a phase with the southern energy, adding more moisture to the system, and also deepening the closed circulation into the mid levels. Again, otherwise, it'll be a fast storm without much banding, and all model QPF will be overdone.

It didn't phase per se ...but that southern energy kicked out a lot more than previous runs and it grabbed some of it.... If this is a trend maybe it will be a more complete phase on future runs....

Than again ..with the GFS it could lose the whole thing next run.

Well if it phases with the southern stream at that longitude, it will probably run up the Hudson Valley or something horrible like that...a phase would be nice, but somewhere over the SE coast or something.

I was just watching those exciting NV caucus returns. LOL ..and figured a model prog. on a storm 6 days away could wait until I finished my snack.

Well we finally got an OP run to show a pretty big event for Feb 11th. 00z GFS is a big hit..esp for interior...but details are irrelevant. Just that it showed some key snyoptic features work out was encouraging.

awt

been harping for over 2 days that this would happen if we got more interaction of n/s streams... best setup since mid jan

agree that details don't matter yet...

to be resolved over the next few days:

- how far southeast will PV locate

- how quickly will a phase occur

- which pieces of energy in either stream will dominate

lots of attn to MJO phase but I think these factors will be more significant

00z GFS looks like its a fraction away from becoming a rainstorm up here as it bombs up the Hudson Valley. Looping that H5 and the SFC, its not hard to imagine that going way west. Just another solution on the table.

That would be the kicker... like the 5th straight "upcoming threat" to find another way to screw the pooch.
