It's a radar reflectivity simulation, the scale is a measure of how heavily snow/sleet/zr/rain would be falling.

Probably has something to do with the fact that that region goes from 1-9 inches in 3 hours (81-84) on the NAM...

Before someone goes ape sh$t and yells at me for posting the hour 84 NAM I have a real question about this... 

On the NAM...  on TT it gives a scale for snow on the bottom right hand corner... what is that scale measuring... and has anyone seen pink depicted for snow before? 

It says mm/hr but 14 mm is about .55 inches of snow... doesnt seem right

I believe that's mm/hr of QPF in the form of snow. Makes sense that a half inch of QPF per hour would be the top of the scale.

For anyone sweating the 18z NAM, and they should know better, the 18z parallel NAM, which will become the operational NAM later next week, has a coastal low just like all of the other guidance.

 

Is that the one based off the 3k NAM nest?

Great video from Bernie. He seems a little bearish south of NYC, but he isn't even all that bullish north of there and is generally pretty conservative with amounts so who knows. Love his breakdowns though.

        It's the other way around.    This is the 12 km parent  parallel NAM, and the 3 km nest is driven by the parent.    TT only shows the parallel nest, but you can see the NAM parent on mageval.ncep.noaa.gov  (it's the NAM on that page).

I like Tasselyer but I disagree that this is a classic miller B. It's a weird hybrid. The low off the se coast already exists and is independent of the NS low well in advance. It's more a marrying of 2 separate systems vs the NS low "giving birth" to the coastal. 

I was wondering about that, because someone posted a discussion this morning from WPC that said it was a combination of Miller A and B.

It didn't look that much further south to me.  Maybe hair

Every little bit counts. 1032 isobar to our north is further south. Both point towards at least a little less worry with temps. Just speculating though. We'll know in a few minutes.

This isn't 3/5/13...GFS has DCA 39/14 at 5 pm

 

heck, that's not even 3/93 (not comparing this to that, but just saying that is an extremely favorable temp profile for this area before a storm).  really can't beat that in march.
