Ralph and his snow porn. :lol:

 

Have we? At 5+ days I am not so sure I would count on that. Don't know how often I have seen a good setup inside 3 days go to crap because the models all the sudden produced a piece of NS energy to screw things up.

Man I'm still traumatized by early March 2018...that stupid GL low is burned into my memory...left us with nothin' but a windstorm...ack! (although I gotta wonder if something like that is more likely in Nina's due to being NS dominant...never trust a nina, lol)

Looks like the GFS is doing just this lol.

GFS late next week looks like yesterday. Frickin atmospheric memory...

That's not what this is...lol if that were the case, there wouldn't be a High to the north at all! (now think about it...when have we even had that this year?)

High to the North and we get rained on?

It's hard to be excited about the GFS being close (but further than it was at 06z) while the ECMWF is 300 miles too far north. Still 5+ days out but with precious little ensemble support, oof.

I was just talking about the rain part. Lol. I see it’s a bit different set up though.

There is nothing to lock any high in place.  We are now and have been all winter at the mercy of perfect timing.   Maybe we can time up the high and low down south perfectly for a snowstorm but my money is on “imperfect” timing.

That actually wasn't far off from a good event for our region. See that drop into the SW a little farther east (100-150 miles) and we might be talking a warning level event. Get that to drop 200-300 miles to the east with it actually phasing (not the sloppy swing and miss we see here) and we are probably looking at a coastal.

This one is not for us.  It would take a major change to be in the game at this point.  The cold can’t hold.  See where we are in 15 days the buy mulch

Another piece of energy to factor in to the needle threading. Too many moving parts and "ifs". I suppose we are due for it all to align, in spite of It being a crappy setup for snow.

But the cold did hold...just a bit too far to the north this time. That high was up there throughout the storm. I'm not convinced it's a "major" change that we need (all winter we've been trying to will storms to hold onto cold air in a stale air mass with no cold anywhere close. This time...it's close)

Edit: I see it ain't as ideal as I thought. But regardless...still 5+ days out...

Look at mid level winds on approach. Cold is shallow and sw flow is running right in line with the upper level ridge in front of the SW. The "cold" is total weak sauce. The real cold and arctic front is up by the Canadian border. As the shortwave approaches the sw flow keeps getting stronger.

Weak cold and sw flow + ridge = good luck here

We do when we have a +AO/NAO for sure. Uphill battle, unless we get some serious cooperation in the EPAC.

Ah I gotcha...Now on the runs where it snowed (like 6z) what was the difference?

I’m always optimistic that we will win one of these and glad you are still posting about the possibilities, but it feels like we are always so close lately. 35 and rain is just a few degrees off of a blockbuster. This week’s huge rain while Texas snowed was really bad. It’s been a truly frustrating winter (for a few years!). Regardless, thank you for continuing to highlight the ways we  might be able to score.

But how close have we ever actually been this year, though?...Weren't the 35 and rain scenarios almost always the result of trying to make something out of a shallow/rotten airmass that wasn't deep enough to hold? (And having no cold air nearby?) I could be oversimplifying this, though...

I noticed you ignored my reply to your question(confusion), but if you look at the differences at h5 between 6z and 12z you have your answer. Minor shifts in depth/timing, and  "new" pieces of energy dropping in can alter this fragile setup just enough. Any way you slice it, its marginal and a lot has to come together just right for it to work out.

Not very different. Even though the ouput was better the inherent problem is identical. I don't think 6z should have any snow for us. 850 cold is weak AF and I'm sure other levels like 800, 925, etc are also going to have their own issues. Deep cold is nearly always a requirement with a southern stream wave. We haven't had deep cold since the first 10 days of Dec. A good rule of thumb is we need 850s to be -5 on approach and the 0c line at least in central VA but NC is better. 

Can a wave on a boundary work? Absolutely but not with marginal air. We need 2013-14 air for that scenario imo

@Ji cmc is good. Keeps mid level winds northerly and pushes back against sw flow. Nice press behind as well. If everything starts moving that way it will drag me back in.

So do you think this has potential to trend positively, or should we write it off still? (I'm a bit confused...I thought that better timing of the waves would produce a better result)
