One more note...this was not an issue in 12-16-07....the high was anchored NNW of Caribou, and it hit with an absolute wall of snow. I think that enhances frontogenesis, especially in the low levels just to the polar side of the coastal front. Now, this antecedent airmass may be a bit more impressive, but usually dry air is fairly easily overcome in intense WAA. Its seems inconsistent to to harp on how proficient the lift looks with the WAA, and then cite the high retreating as a positive to help overcome dry air. Not sure I buy that, and view the retreating high as a negative. if the WAA is that impressive, then...dry air? Really?
