That run would shorten the period of deep max DGZ for many too. It’s probably just the NAM doing its own synoptic things rather than nailing the mid level warming.

NAM is juiced

It would’ve been funnier if Cory came back and then the RI snowhole reemerged.

Exploding showers when the cold comes in behind it

They were probably getting pushed for a map and finally said “fu here ya go”

Every run is pretty much in that 0.8-1.1 range up here. 10-16” sounds good barring any changes. Hopefully we can really crank the latent heating in the south.

My family will text me later ”is it true we’re getting 3ft of snow over the next couple weeks?” -

The 540 critical thickness was more important in forecasting in the 1990s when we were more limited on the model data we received. It’s definitely outdated now. Usually it can snow even with a 552dm thickness in these overrunning SWFE setups.

It’s the thickness of the 1000-500mb layer and it’s dependent upon the average temperature of the layer. The warmer it is…the more it “expands”…the taller is it. The colder….the more dense…the lower it is. But this isn’t a standard avg 1000-500 layer…this airmass will be biased cold in the lower half and warmer than average in the upper half. So the 540 thickness rule of thumb for RA vs SN doesn’t really apply. Forecast soundings are better and easy to find for all models today. If you’re going to bother with thickness it would be better to use partial ones like 700-850 for midlevel warming.
