Euro saved the day thus far.. really was not overly impressed with 0z guidance at least not down this way. Hoping GFS comes in less amped. 

Watch the NS energy across eastern Canada moving into the the 50-50 region. That needs to dig more. The last few runs it has been flatter, thus less confluence and a somewhat weaker surface high that retreats a bit. The timing/interaction there is an important factor for places further south and the coastal plain imo. Increased confluence would encourage the low to track a bit further south.

^IMO, it would take a complete miracle for that to be all or mostly frozen in these parts. If that happens I'm going streaking. :tomato:

We've seen this stuff in past morph into a weaker solution with a front end thump/dryslot. Ops often back down on strength with big cutters a week out. Get a modest wedge with snow on the ground and I can easily see it be a mixed event with decent accums (2-5"). We've had many in the past buy they aren't too memorable because of dryslot drizzledrip and slush when it shuts off. 

Either way it looks like a juicy storm cutting west is in the works no matter what. We'll see how it goes

6z GEFS is acceptable. Colder and continues with a more SE track than the op.

 

 

 

Not having the mids get lambasted with a primary to our west driving to or north of our latitude is a huge relief. Even the improved airmass on guidance can't offset that. Need deep cold. Seems like now we are just watching wobbles with a favorable but a bit too close track to our SE. Not a bad place to be right now. I know what you're rooting for and I'm good with that because if you get hit flush, my property in VA will as well. I'd prefer to be down there for a good storm but opposite direction usually lol

lol. We are not locking anything in. But I will say I’ve observed in the last few years since the major upgrades to the gfs and euro, there is a pattern where they start to narrow in on the general synoptic solution around 140-160 hours out.  After that the changes are more subtle. We’re marginal so subtle could be big for our ground truth but once inside day 6 usually it’s not adjustments of 500 miles like it used to be. They even picked up on that crazy anafront wave from 5-6 days out!  They still have limitations but since the last upgrade they seem to start identifying the basic idea a couple days earlier than before. I know we haven’t had many chances to test this locally but I’ve tracked storms for my various ski interests over the last few years. 

Yeah and we have been burnt really bad on 96 hour leads where all the sudden the entire storm shifts 100 miles on all the guidance all at once.  Heartbreak city.  This is why I just refuse to go all in any more on anything even with a winter storm warning in effect.

Generally speaking, that usually only happens with progressive flow and northern stream systems. Slower moving southern stream systems with any kind of block are modeled pretty well by 96-120 hrs. Doesn't mean a 20 mile shift can't destroy hopes and dreams tho lol

6z Gefs has pretty much dropped the trouble to our west. Only 1 member driving a low into Ohio. The rest are money. This is a beautiful panel really. Could be the op wagging the ens but either way, track is locking in for now. If 12z and 0z tonight don't wiggle much then it's pretty safe to assume there will be few if any big shifts going forward with storm track. Significant ground truth shifts will occur every 6 hours tho hahahaha lol. Imma just hug the snowiest from here on out. Never fails... to punch my dreams right in the face :lol:

Looks like GFS really cut back on precip after the overnight monster run. Might have to do with the shift to a slightly colder/less amped solution. Interesting to see how the storm has sped up so much in time. I feel like most of the time, our storms usually move back a bit in time, not up.

Which is honestly fine. I’d rather have 6 inches of straight snow rather than 7.5 of slop and ice.

EPS is basically just as sweet but I like the PAC on the GEPS better. The entire d10-15 period looks amazing from a pattern evolution perspective. I mentioned this in the last couple days that the PAC was primed to get right and this panel shows it perfectly. Split flow, all 3 streams meeting somewhere in the middle of the conus, potential shortwaves aimed at us from the pole, pac nw, and some pineapple connection. The magnitude of the west based block showing up at long leads is jaw dropping at this point. Lovin this man.

Exactly what I said multiple times last night. Snow on the ground = at least some cad and the scenario you wrote
