Here's a bit more detailed version of that UKMET map. For reference, 12z had 0" QPF for DC and points north.
-
America hasn't won a war since 1945.. feeling pretty confident that the GFS folds here.
-
-
RGEM looks like .4" QPF through DCA. 18z was just barely 0.1", so I would say that is a definite improvement.
-
The LP goes due east right after that panel.. it's quite the ensemble member :p
-
Def looks to have improved for folks East of I-95 compared to 12z. Our snow attributed to the NS feature looks somewhat similar, if not a bit lighter. Hoping the mesos give us clarity on that soon.

Early on with the 18z Euro.. it looks like our Four Corners shortwave has stopped bleeding west, at least compared to 12z. Probably won't have much significance, but at least it's something.

I recall him being a bit pessimistic for Jan 3rd though

I've definitely seen worse.. it's interesting that the ensembles are once again diverging from the OP at this range, much like last week's storm.- 4,130 replies

FWIW, the GEFS has the AO nearing neutral at the end of the storm (~0z Jan 31st). That at least can't hurt, but yeah there is definitely a ceiling given the pattern.- 4,130 replies

hmm.. SS energy is a bit more held back at hr 102 for the GFS compared to 18z.. might give it a bit more of a chance to separate from the northern stream energy Slightly healthier press of cold air as well..

Jan 21 - 22 Weekend SE VA and Eastern Shore Snow
Cobalt replied to stormtracker's topic in Mid Atlantic
I've heard the St. Louis subforum is bustling this time of year. -
The trend so far this January has been for the NS to be modeled as faster when closing in range.. reel this one in!
-
Probably still a bit far west, gotta throw in a Dec 2010 for good measure
-
Definitely showing up more on the 12z EPS compared to recent runs.

Jan 21 - 22 Weekend SE VA and Eastern Shore Snow
Cobalt replied to stormtracker's topic in Mid Atlantic
Actually, the GFS seemed to be the best fit model for Jan 3rd. I was under the belief that this was due to the model's handling of the northern stream, modelling that piece of energy to be faster than any other guidance, which caused it to get out of the way faster and allow the SS shortwave to amplify. Someone can correct me on this, but I do definitely remember that it was showing glimpses of decent hits at ~60-72hrs out, but upped the ante with other guidance following suit shortly after. -
Negative teens into PA Friday morning (on the mean, which should have its cold be even more muted). Couldn't ask for a better airmass.

Mhm, would probably give us some more wiggle room if it meets in the middle with the GFS/Canadian Also, that HP strength and positioning looks even better compared to 12z. Real stout one over top
