Yeah I've been waiting for that Grinch storm to start getting muted...based on the longer wave features. There's some risk of a cutter there, but we've been seeing a transient 50/50 feature and a -NAO that could try and put the squeeze on that trough a bit.
The Grinch storm basically fails this run, but it doesn't result in a snow event for us....at least yet. More like a quick FROPA and then a weak wave along the front Xmas Eve night that doesn't do much...maybe give us a little bit of light snow. At least we're not ripping 55F+ dewpoints into New England like on some other runs.
