Its cuts everything off a bit sooner/further south so it loses its cold air drain from Maine sooner. The dynamics look weaker too which also plays a factor.

 

 

A good visualization on a loop is this:

 

00z NAM: http://www.meteo.psu.edu/~fxg1/WRFEAST_0z/wrfloop.html

21z NMM: http://www.meteo.psu.edu/~fxg1/ETAEAST_0z/etaloop.html

 

 

Notice how the 21z NMM has the upper air low further north and doesn't pinch it off from the northern energy as soon...thus it is much colder than the NAM which cuts it off from the north and drifts it east.

lol DT...grasping at anything for his 2-4" call.

 

 

‎** HUGE SNOW FOR NEW ENGLAND COMING ***

Um.. not this is the 15z SREF.. short range ensemble forecast
it takes a mean of 15 weather models to see what the % says

as you can see the chances of NEW ENGLAND 8" of snow are under 20% ... Much less 1-2 feet

 

 

 

 

He forgot to mention that those probs are for every 12 hours...and where he has forecasted for 12" is also under that same 20% for 8". :lmao:   :facepalm:

NAM doesnt' really involve the northern s/w at all until very late in the game.  That's different than all of the earlier models including the 12z Euro.  I'm tending to think this is the NAM whacking it and not finding the golden nugget. (as it pertains to the 48+ hour time frame, not speaking of down the coast)
