Can't believe I'm even going to bother with the jma but it cuts off too far south and stalls and we are under easterly fetch too long. Adjust it north some and the thermals would be fine.  Don't and the precip we get from the initial waa would be over and just snizzle by the time that warm layer invades but the big snow would be central and southwest VA.

If JMA is in then "nuff said"

I too noticed the undercutting on the closed ridge out west. Seems that lower heights are pushing in quickly on the coat tails of our SW.

 

This is the GFS @108. You can see how the ridge is getting compressed which from a timing perspective effects our system down stream. Specifically, limiting the toughs amplitude to dig and potentially making the whole system more progressive. The current GFS isn't kicking our SW out as quick as the EURO is with its fully closed off ridge solution. 

I'd like to see better spacing of the two southern stream shortwaves or less amped solution of the trailing SW

EPS clearly favors a weak/strung out progression. Very few GFS like solutions. Vast majority give us at least light snow so that's good but overall it's not the run  we're hoping for

I don’t really fear a weaker solution at this stage in the game. Might be better if the wave stays flatter anyways as to avoid riding the line on how mid-levels perform with an amped scenario.

Id gladly take an all snow 27/28 degrees 2-3” event :)

132 it closes of the ridge out west.  On a mean that is impressive.  Also has a stronger trailing southern stream vort.

The only disappointing thing is there are very few warning level events in the mix and basically none that look like the gfs. A cold light event would be great considering how awful this winter has gone but the eps showing very limited upside across the board is a bit of a bummer.

the euro has never liked the event. The GFS will pull the plug likely now in the next 2-3 runs?

If the gfs has the right idea then it's a pretty big eps fail considering the leads aren't that long

EPS was a step forward though.  Better 500 and surface/coastal low depiction.  The nondispersive nature of the ensembles (GEFS and EPS) makes me wonder how well the true probability distribution is being covered.

Yea, that part isn’t great for sure.

I think you’re right I’d definitely be disappointed if moving forward over next 2-3 days we didnt have some big solutions in the mix.

I currently think (could change) that a more modest solution is the most likely. Either way, I’m hoping for a good track on this one. Been bored with this current pattern, sheesh.

The Canadian ensemble doesn't look great either.  Only 5 / 21 members give me an inch of snow, and it looks like the low is suppressed on the mean.  The control is the best member for the region.
