I would say that's a decent shift. A few  ticks west with that vortex crashing into pacNW and that ridge is in a better spot. I can feel PB starting to smile somewhere...

That 96 hour frame should give anyone other than Atlantic City folks, or Cape Coders flashback nightmares

PB should be smiling at the latest guidance. He was onboard for another possible snow event after this weekend.

I’m once again amazed at how poorly the GFS is performing.  It’s a complicated setup with many pieces given you have activity here and in the MA and mid South. It has some parts close to other guidance but as a whole though it’s just so different than anything else.  It’s missing the Arkansas Tennessee Mississippi snow almost entirely

I’ll leave it here...This is a bad setup. Flat, progressive, fast flow, +PNA ridge getting crashed into and knocked down, the mean trough is positioned too far east and positively tilted, wave 1 pushes the baroclinic zone way off the coast

This will very likely be a light snowfall event for NYC and nearby areas. Parts of New England could pick up a moderate snowfall.

You can see the gfs starting to come west with wave 1

Our real shot is 1st wave, the disturbance out west crashing out Ridge isn’t helping either, the trough axis and position of the ULL isn’t remotely favorable, I’m a weenie ;) , but I just can’t materialize a way wave 2 comes up coast, if we can’t trend our 1st wave closer to the coast and amplify our lead SW, once it hits warmer waters we can pump back some moderate snows into the area and into SNE... I’d say 3-6” is our high shot with 1-3” more likely

My thinking is that wave 2 isn’t a player for most of our region.
