The best case for us along/near the I95 corridor is a WAA thump that transitions to a light sleety/rain mix, or even better, drizzly dry slot, so the rain doesn't wash all the snow away. We've seen setups like this over the past several years, where that heavy rain phase doesn't come to fruition because of the timing of the transfer and a more pervasive dry slot than what was originally advertised 5 days out. I'll gladly take 4-6" of a WAA thump followed by drizzle. Expand Same here, I'd gladly take that. I like your point about the advertised "washout" rain that typically ends up turning into a quasi-dry slot with light sleet then drizzle. Feb. 2014 has been brought up a few times and that's what happened in that event. Maybe we'll get a little more light snow after a dry slot, too, if we're lucky. 1 Link to comment Share on other sites More sharing options...

Good declarative statement at this point. Kudos. Expand I guess. Just don't see how this screams clean hit. Almost zero guidance supporting this so that statement is not unrealistic.

Roger Smith Posted January 12, 2022 Share Posted January 12, 2022 Two different ways to a roughly similar outcome now, why mess with that? The ICON has a high energy coastal and the GFS has a low energy associated low with a weak inland primary tracking KY to upstate NY. The low energy keeps the Atlantic from rushing into the circulation. I suppose the best case scenario is a high energy coastal that ripples back a bit to the east of the current ICON track. But given this is the third significant snowfall in two weeks of early to mid January, this seems quite acceptable if not downright astonishing.

Roger Smith Posted January 12, 2022 Share Posted January 12, 2022 CMC is the worst outcome I've seen in this time frame, while somewhat similar to GFS, there is almost no definition to the coastal and most of the energy is shown with the inland primary. It would snow a bit and then thaw. However, it is the CMC so not to worry. Link to comment Share on other sites More sharing options...

MillvilleWx Posted January 12, 2022 Share Posted January 12, 2022 Current National Blend of Models 50th percentile for the region through 00z Tuesday next week. This displays a pretty idea of what the current thinking should be given everything we've seen so far. Meso-banding and other parts will of course change localized amounts, but this is solid for a smoothed mean. 9 16 Link to comment Share on other sites More sharing options...

There's a strong consensus here of what's going on and it's clear as day this is NOT a PHL area special. I remember days ago people were like oh no the models are wrong it's so darn cold this has to be snow! No, it's not wrong. The models show what they show because it reflects reality.
