  1. GFS is awful for this area.....folks can stop lamenting the NAM
  2. RGEM is a general 4-8"...ignore the @Dr. Dews generated temp algorithm.
  3. Euro seems pretty damned locked in....I would be surprised if it is way off at this point....maybe developing the low a bit too quickly..ie NE shift, and/or w or east up to 40 mi or so.
  4. I'd take that that and run. I think the only guidance that blows for me is 12km NAN and RPM.
  5. I think I had you near the edge of 1-3" and 3-6"....may have to edge upward. We'll see...I think the 18z EURO was the high water mark haha
  6. Walt, I've been waiting for the "late development" rug to get pulled out from under NYS for a few days. W NE is close...as you know, fine line between midlevel haves and have nots.
  7. Whoo.... lol. I'm just screwing with you. NBD, but I'm quite confident that if you took a poll, the vast majority believes that you own a DIT pin cushion.
  8. I would not worry....snow will get thrown back farther up there bc mid levels will be mature.
  9. Are you talking about the QPF charts, or mid level model depictions? if the mid levels trend east, and/or the system matures later, then yes.......but not because the QPF chart simply doesn't show big amounts. Models mainly resolve precipitation from low level forcing, but are not skilled with mid level deformation...vastly underdone.
  10. Exactly. The snowfall algorithm that I tout is superior with respect to distinguishing precip type issues, which is usually important for us. Most algorithms err by tallying mixed precvip as snow, which inflates the numbers. Mine does not to this, however, it is only based on the model, which usually will not resolve mid level banding properly. Thus it will miss the deformation axis to the NW of the low.
