I figure to be doing the same thing. So many east coast storms to relive. February 12 2006 was a great event, I actually was up in the Adirondacks skiing, and all we had up there was cirrus. Sent from my SM-G965U using Tapatalk

Weather.us has a sweet reanalysis page that they must have recently added. https://weather.us/reanalysis Sent from my SM-G965U using Tapatalk

The 12z Euro ensemble trended much colder into the first few days of 2020. Not sure if WxBell images are fair game, but here's the day 10-15 500 mb height anomaly prog.

The ensembles don't look half bad for the end of the month with both the EPS and GEFS in agreement on a -EPO/-PNA alignment. Obviously far enough out/subject to change and no guarantee of a spread the wealth snowy stretch, but reasons to be cautiously optimistic if we can get that look inside 10 days.

Looks mostly dry so if Monday works out we'd probably only gradually melt it and temper the warm-up. Sent from my SM-G965U using Tapatalk

I haven't noticed it to be a significant issue, maybe with a few events, would have to collect some verification data to know for sure. The Euro was even too wet locally with some of the early season snow systems this year. Sent from my SM-G965U using Tapatalk

The GFS has been atrocious all cool season. No reason yet to put much stock in it until more modeling supports it with next week's potential system. Today's 12z EPS has less members getting snow up this far north. Just have to hope the blind squirrel finds a nut this time. Another note on GFS/GEFS: the GEFS has always been known to be inferior to the EPS because it has less members and it's too non-dispersive (runs too close to the operational). The "upgraded" GFS and the current iteration of the GEFS aren't even based off the same physics package, since the GEFS hasn't been upgraded to the new GFS physics yet. So that probably makes it more of an apples to pears comparison between the op and the ensemble now. The ECMWF and EPS will certainly have misses (such as what it showed for Saturday just a couple nights ago) because it's still a computer modelling system, but it's by far superior and perhaps the gap has grown despite the large sums of money poured into the GFS.

I'm more interested in the Saturday threat for now. Pretty complex setup but 00z Euro with a nice outcome for parts of northern IL into IA and WI. 06z EPS seems to favor farther north but hopefully some of us could score something, with possibility the next week threat ends up farther east.

Euro ensemble also with a chilly and active look at h5 out out beyond the early to mid week cold shot next week. Sent from my SM-G965U using Tapatalk

This is probably an obvious statement to make, but we did check a few years ago and there's a strong correlation between precip anomaly and snowfall amounts. CPC has essentially the entire subforum in enhanced probabilities for AN precip in the DJF and JFM outlooks. They also have a lean toward cooler anomalies for a portion of the sub in the JFM outlook. So if the above normal precip works out, that would seem to increase the odds for above normal snowfall when also accounting for the head start, unless it ends up being a blowtorch winter.

And then the Euro completely backed off lol Sent from my SM-G965U using Tapatalk

This isn't a bad thing either for when (if?) a significant pattern change occurs. The slow ULL movement caused by the omega block will produce a very favorable heavy rain setup in the Plains, with a midlevel moisture feed from the EPAC and low level trajectories from the Gulf.
