I really have trouble biting on anything outside of 7-10 days. Beyond day 10 and especially day 15 it has been pure speculation last several years. Modeling has been very "jumpy" it seems to me. Taking OP runs surface features as anything more than "interesting" is foolhardy. 1 Link to comment Share on other sites More sharing options...

donsutherland1 Posted Monday at 06:49 PM Share Posted Monday at 06:49 PM So far, the GEFS continues to suggest that the strongest shots of cold during the evolution of a colder pattern in January will dump into the West. There remain questions about the timing of the onset of the colder pattern in the East. The EPS (through 0z) had remained faster than the GEF (through 12z). Both support the development of a pattern that could become more favorable for moderate (4"+) or, if the PNA+ persists, significant (6"+) snowstorms than has been the case all winter so far. Whether there will be short waves present to produce the storminess remains to be seen. Below are cases for severe multi-day cold shots that reached the East during the first half of January (1980-2024). Finally, the cold start to December and 1.8" snowfall to date in New York City make it unnecessary to post "winter futility charts" at this time. Indeed, out of 156 winters (which includes 2024-25), Winter 2024-25 ranks 65th worst in terms of cold and snow (standardized basis) through December 22nd for New York City. 2 Link to comment Share on other sites More sharing options...

EastonSN+ Posted Monday at 07:18 PM Share Posted Monday at 07:18 PM Gefs gets to the following look which must be due to a spread in The ensemble members. If this look were to verify I would think that the risks would be systems being shredded or weak into the South. On a side note I can never tell if forky is teasing the forum or has legit concerns LOL. 1 Link to comment Share on other sites More sharing options...

Could be nice for the interior portions of our sub. Interior New England would clean up. But I'm definitely not a fan of long range forecasting or looking at anything post day 10 so *shrug*. While the long range ensemble forecasts beyond a week can vary quite a bit, the model error has been very consistent. The December long range forecasts issued back on December 1st underestimated the strength of the Pacific Jet. This lead to the 500 mb heights verifying lower than forecast over the EPAC south of Alaska. This allowed the ridge to drift east at times instead of staying anchored out West. We have seen some version of this model error every winter in the Pacific since 15-16. So now if the models are showing lower heights over Western NA than there were from earlier runs, it’s possible we see some version of this pattern repeat heading into January. The other issue has been the tendency for long range -AO forecasts to link up with the Southeast Ridge at least transiently when lows are ejecting from the trough which has been so frequent in the West. Just hoping we can get enough overlap between the fading +PNA and the emerging -AO to at least get a shot at a 4” snow event for NYC. But there are no guarantees with the way the Pacific has been acting as the spoiler since 18-19. 3 Link to comment Share on other sites More sharing options...

It's an overall chilly look for basically the entire country but when systems eject out of the west they'll want to cut and redevelop with a look like that. 2 Link to comment Share on other sites More sharing options...

Will be interesting to see which way the EPS leans. 1 Link to comment Share on other sites More sharing options...
