January 28-29, 2022 Miller abcdefu Storm Threat

I'm a novice at best so there's the caveat, but based on my understanding of psu's analysis last night looks like the pieces are playing together relatively nicely and piece 'A' has a North-South orientation rather than NW-SE that gfs wide-right was showing. I liked how that example still had a N-S component and wasn't all 'diagonal', which is hopefully closer to reality.

Some random thoughts as we prepare for todays guidance.  

1) This is not necessarily pertinent to the current euro runs...(but it could be) but once we get within 48 hours beware if the euro and NAM are both west of all other guidance.  Right now the NAM is at a range where its going to get major synoptic features wrong so it doesnt matter...but the final 24-48 hours both the NAM and EUro have a notorious over amplified west bias with these miller b storms. Together they are responsible for the worst busts and teases that have happened.  They were the models that teased NYC with 30-40" of snow in January 2015.  They were the models that teased my area and northeast MD with 6-12" in early March 2018 when we got nothing.  They were the furthest west and overdone with the western fringe in the 2018 bomb cyclone and the 2017 coastal scraper and teased Baltimore for a time when the back edge ended up east of the bay.  Other guidance was too far west with some of those also but only barely...they were by far the worst offenders each time.   Just keep that in mind if in the final 24 hours the NAM and Euroare showing the deform crushing us but the consensus of all other guidance is just east of us.  And frankly...no matter what the guidance shows I would adjust the back edge about 25-50 miles east of what it shows 24 hours out...because 90% of the time that is what happens in a miller b.  

 

2) Our best bet to not get totally skunked is the snow associated with the NS wave like @WxUSAFhas been talking about. 

3) I am praying for a miracle just like everyone else and just as excited when some run comes in that shows maybe, just maybe, this is the rare exception to the rule and we are in the game for more than just scraps.  But I think everyone should simply admit the reality of how 90% of these types of storms end.  We have tortured ourselves with plenty of these over my lifetime.  We tracked that 2015 storm that ended up crushing eastern New England until it was obvious we were out of it inside 48 hours.  We tortured ourselves trying to will that bomb cyclone and the early March 2018 storms west.  I could go on and list like 10 more examples of similar setups to this but if I brought up some of those dates @stormtrackerwould have to ban me.  

That is not to say there is NO hope... once every LONG time a crazy anomaly can happen.  March 1958 is probably the best example of a miller b that initiated a coastal storm way southeast of NC and captured and tucked it back into the mid atlantic coast and bombed us.  But that had some extreme blocking and it was March with shorter wavelengths....so.  The Feb 95 storm is a really close match at h5 but at the surface that had a bit more STJ interaction which is what I was hopeful for a few days ago.  From range my hope was the NS would dig a bit further west and link up with the stronger STJ wave in the western gulf.  It seems pretty clear that is not happening and the STJ gets left behind here and the NS goes it alone.  That changes the equation if a not good way for us.  

The type of progression we are looking at is mostly a fail here the VAST majority of the time.  SO I really think we should look at this as if we are huge underdogs and if we win great and be thankful but not get all bent out of shape if things trend towards what climo says is the 90% probability and we all should expect.  Save the "why is this happening, the sky is falling" crap posts.  If it goes that way its because that is normal climo for how these types of storms usually go.  Its normal and should be expected not treated like the universe is so unfair.  We know our climo and we all choose to live here so....suck it up.  

Now on to rooting for the 1 in 100 type fluke to happen here!

12z is it for me.  I'm either tapping out or going all in.

At least it seems like even if the coastal doesnt necessarily pan out, we get some consolation with the northern Branch and maybe a 1-3/2-4 area wide.

I've noticed a lot of these runs, even the ones that drop nothing on the DC/Balt metros, crush Garrett and Tucker counties. Is that wraparound as the storm moves NE?  And is that typical in a Miller B scenario?

It's a combo of the NS vort and then upslope.  The orographic lift will squeeze every drop of moisture out of that NS vort.

Ah got it.  Makes sense.  I was in Canaan in 2016 for that storm and was getting worried when there was very little snowfall initially the first day while NoVA was getting crushed, but later that night the upslope kicked in and they got 2 feet.

the more i look at this system, the more i think we (folks west of i95) want to rely on a more vigorous ns sw (the northern piece).  i'm basing this on as-is...obviously, if that piece dives in further west, we're golden, but that's not the case at least on the gfs.  so "as-is", i'm in agreement with what others have said that we may want to bank on that energy being legit enough to provide us with a classic "clipper-like" event for the western folks and then if the phase can occur soon enough to toss precip back against the mountains, then big bonus.

Those areas always seem to do well when the metros get the big ones because of the wind shift behind the deepening low bringing that upslope hard-core

ICON at 84 shows some improvements over 6z to my untrained eye......

it bombs out late, but it's workable.  need a closer to the coast track, most likely.  it's becoming a little clearer what's needed for this system to work out here.

I'm more in the Wwxluvr camp, it hasn't been that great of a winter out here to the NW... those who say we win a lot, suit yourselves but I want snow. 

I have had snowpack here for 20 consecutive days. So I am not going to complain. Of course I would like to freshen it up though.
