Enjoy. I’ll be in nyc. Bf got selected for a modeling gig in NYC. I’m sacrificing. Sigh.

You said it was fools gold but then said the NWS was wrong and the CAD was underdone.  But if the CAD was underdone then it gives more credence to the Euro AI solution vs the rainier physics based model solutions.  Your two posts together make no sense.

Lastly, the Euro AI has the highest verification scores on the planet right now.  So your comment about it not being ready for primetime makes no sense to me either.

verification scores on the placement of global 500mb anomalies don't mean much for events like this. None of these models are verified based on ptype

But he said the CAD was underdone, which would lend credence to the ptype it was showing.

Also, the physics based models have all started to say the same thing, lending even more credence to the AI solution.

I mean moist adiabatic lapse rate is around 4 degrees Fahrenheit per 1000 feet so if you're just looking to see snow and willing to drive out to the mountains/Shenandoah we are really just focusing on the 850mb and 925mb temps to be at 0 or below. As long as we have that we should be good for the mountains.

@EastCoast NPZ is going to get pummeled.

this is actually a legit event to use an umbrella in the snow

Hello again my friend:

I suggest that the NWS idea of limited CAD was "wrong' : This would create support for the AI solution.

The EURO AI deterministic is fine.  But the EURO AIFS ensemble is not ready for Primetime. Maybe next winter, but not this year.

devastating step backs from the 18z runs......onto 00z---it might be time to call it by 12z tomorrow. The low pressure in the south is just so weak

It sucks…I wanted a good rainstorm to wash away “whatever you want to call it” that’s still on the ground.

Weak and south wont do it. This has always been about a strong low, which requires a damn near perfect phase at h5, and a perfect LP track, with heavy precip and dynamic cooling. A lot to ask for just to get it to snow moderately. The antecedent airmass is pretty bad.

It would’ve been nice to see the euros improve but such marginal cuanhes from their previous OP runs. See what the ens say in a sec (I’d gamble they are worse, but ya never know)

Only about 1/2" less
