Kitzbuhel Craver Posted January 23, 2021 Share Posted January 23, 2021 Man that thing is a beast... wherever it ends up going, could be THE event of the season. Having said that, if it’s a mid Atlantic crush job while we smoke exhaust. That’s gonna hurt, real, real bad. Link to comment Share on other sites More sharing options...
CoastalWx Posted January 23, 2021 Share Posted January 23, 2021 Yeah I'm not getting hopes up too much with it. I'd like to see the euro a little more on board and closer to the GFS. It's still a miss, but something like that at least allows some wiggles NW. Maybe I'm just delusional with hope. LOL. Link to comment Share on other sites More sharing options...
SnowGoose69 Posted January 23, 2021 Share Posted January 23, 2021 The Monday and Tuesday system has some sort of impact as usual. I don’t think it’s big but it might influence the big one enough to make a difference, especially in SNE. The lagging surface reflection that cuts across PA towards NYC Tuesday I think can eff stuff up possibly on the Thursday event. Might want that feature to wash out even though I think it could deliver a surprise snowfall to western parts of this sub forum Link to comment Share on other sites More sharing options...

40/70 Benchmark Posted January 23, 2021 Author Share Posted January 23, 2021 Part of me expects the EURO to nod in that direction of being more suggestive of N stream interaction.....I mean, we are only talking day 5 for these changes to manifest. I have a hunch the GEFS suite is not incorrect in trending in that direction. Doesn't mean a hit.... Link to comment Share on other sites More sharing options...

Don't expect the prayers to be answered however. How about a stronger Jan 15 system. The upside is huge for the 28/29th system, the problem is, how do we get to that solution? Right now, there are three options: 1.) PV lobe phases west and earlier like Ray said, 2.) a partial phase happens too late and a non event happens, 3.) no phase happens and we get a 12z GFS solution where the E Massachusetts coast gets a long NE fetch of cold arctic air producing OES!

Best chance is to keep that PV lobe in central Canada close enough that it may try and inject a little energy into it or at least be far enough west that it bumps up the heights downstream in Quebec. 1 Link to comment Share on other sites More sharing options...
USCAPEWEATHERAF Posted January 23, 2021 Share Posted January 23, 2021 I am guessing there is a large spread as well with the EURO ensemble individual members. I would like to see the next few days how the interaction with the PV lobe behaves in the guidance. Today's 12z runs have intensified the surface low into a sub 960mb low. Honestly, with a circulation as large as the models have it, there is a high chance someone east of the CT River Valley gets a few inches, maybe low end warning criteria snows.

I am so sick of the blocking...its been nothing but a death sentence for this winter. I get the risk of cutters, but there is no way in hell you can tell me that we wouldn't have had more snow without it. This is like a toned down 2010 with less snow.

Will, I noticed with the GFS runs that showed an impact from the 29th system showed a much stronger ridging presence between the PV lobe over central southern Canada, and the large vortex over the 50/50 location near Labrador. If the PV lobe stays west and does entrain some energy the surface low will track further west as it gets captured and intensifies with a sub 528dm upper level closed low. 850mb temps are extremely cold as modeled! With a hurricane force wind field as large as it is being depicted, there is a strong chance for at least a few bands of accumulating snows. The 12z UKMET did move more northwest this afternoon compared to the run last night! Link to comment Share on other sites More sharing options...
USCAPEWEATHERAF Posted January 23, 2021 Share Posted January 23, 2021 The biggest difference is not with the central southern Canada (Ontario Vortex) but the vortex east of Labrador. The vortex north of New Foundland crashes the growing ridging ahead of the main shortwave trough as it exits off the Mid Atlantic coast. The GFS and ensemble mean compared to the GEM show that the GFS suite is more amplified with the ridging over the Maritimes and NW Atlantic Ocean, while the GEM and the models that are less friendly crash the ridging and deamplify the shortwave trough therefore it enters the western Atlantic Ocean off of NC instead of the Delmarva. 1 Link to comment Share on other sites More sharing options...

Our miracle comes with the models hopefully over estimating the short term strength of the confluence over the Maritimes and ahead of the shortwave trough as it reaches 75W longitude. Right now, the best bet for changes are the placement of the PV lobe over Ontario, potential phase and timing, as well as the confluence/vortex circulation over Labrador. 1 Link to comment Share on other sites More sharing options...
USCAPEWEATHERAF Posted January 23, 2021 Share Posted January 23, 2021 12z ICON is the most dramatic with the strong presence of the vortex over Maritimes. I am guessing since it is way off the reservation compared to the GFS, GEM and others, the ICON is the least likely solution and therefore a southern outlier with the UKMET, except that model came more northwest compared to the 00z run which was off Bermuda.

USCAPEWEATHERAF Posted January 23, 2021 Share Posted January 23, 2021 Basically you have a consensus when confidence increases that an event will happen. This begins to occur as you get within four days of a single event time period. However, since the models are still at great disagreements at day 5 still with the handling of the Labrador (50/50 -NAO vortex) vortex and the Ontario (-AO) vortex and how they will interact with the 29th energetic shortwave trough, uncertainty for the 29th is still at great lengths. Right now, I am declaring the next 48 hours as a toss up to whether or not this system impacts SNE. The 26th system is dead for anyone east of the Connecticut River Valley, anyone east and south of the Pike is in the game for 2-4" still. Right now, we can just sit and wait for whatever the models trend towards the next two days! Oh and the energy for the 29th storm is still off the British Columbia west coast!
