I like your excitement about 14 and 15. I really don’t remember specific storms those years, just that we had several hits, and some fairly big. Those were 2 great winters here, which is why, in my opinion,  so many people were disappointed in ‘16 when we only got 1 Storm (even though it was of epic proportions). I could be wrong, but I remember reading that we had blocking due to the displaced PV rather than a -NAO for much of 2014 and/or 2015. 

Those really were great winters!  What was the ENSO state those years?  2015 had some unusual events like that decent anafrontal snow plus a big hit by a low moving well to our west that stayed all snow.

If that deal this weekend hits south and east like Jan 3, the snow totals to date for say  Frederick compared to Huntingtown will look funny

12z rgem looks decent at end of run. Could see the cmc show a hit today. That Texas energy is important it seems to partially phase with main shortwave and slows it down allowing it to turn corner

Way better than the GFS, which has an ugly gap between the northern and southern streams.  RGEM should at least phase half of it.

The GFS is irritating my soul right now.  Hopefully Euro looks like RGEM and then I can rationalize chucking the GFS, although deep down, I know it's probably gonna end up right.

Strange times where we get upset when the Euro shows a storm and the GFS doesn't because we know the GFS is probably right.

It doesn’t because I don’t have the weather memory so many of you have. :lol: All I remember is that it was cold and we had a never ending series of vorts flying around the PV that gave us shots at snow.

I wish I had been keeping notes on our snows back then…

Dude, that's all you need to know. This is a short/mid range game and it looks "stable" which is kinda an oxymoron because progressive and stable don't jibe but 2014 and 15 had these periods of tracks getting laid down then traffic riding them. Precip shields were all small stripes. But the tracks were aimed at us enough we kept hitting. Time will tell, but this already has that feel. Hit a few more events of any size really and it's practically identical imo

Got it…and that’s kind of what I figured.

Given that I’m sitting at about 75% of climo at this point, I’m fine with being patient until discrete threats for MBY come into reliable range. Good thing is that we don’t really have to wait long. If a threat looks to miss, there should be another one on its heels that we can keep our eyes on.

As for this weekend-ish threat period, I’d like to see the GFS at least make a move today towards getting us snows. If we don’t see that today, then it’s getting a little too close to gametime and I’d be a little afraid that this one will slip away.

Agreed.

When the gfs says no....its usually no

If the GFS is right, it would be a disaster.  But thankfully, it's likely confused with all that shit going on at H5.  Changes every 6 hours.

idgaf about cold if there is no snow. i gotta walk/bike to class, lol. and stumble back home from the bar. Might as well be 70 if its not snowing 

Yeah but it’s handy to have around when precip arrives.  Looking at NA view it’s cold up there too…and looks aimed toward the east.

I really like what I see down the line. Continental cold air factory appears to run unabated thru early Feb at least. We don't want a big hilly amplified pattern either. I saw some people posting ens mean maps like this a week ago and my first thought was cold/dry and not snow.

IF ens means have it right, the PNA ridge is going to retrograde and turn the entire conus into a more broad/zonal trough with cold air wall to wall in Canada. With Feb wavelengths shortening and cold domes pushing hard against it, storm track could run WSW-ENE from the middle of the conus easterward

gfs-ens_z500a_nhem_61.png

I'm using the gefs for visual reference only. All ensembles have their own version. If we start getting attacked by shortwaves approaching from the WSW, I'm going to get pretty excited. I don't like tracking big amplified storms running uphill nearly due north on approach. Too much can go wrong and volatility wreaks havoc. I like highway style storms that elongate and run along tracks more W-E than S-N. Hard to get a hecs that way but it makes it really easy to get 4-8" of all snow and no temp worries

I agree with that last statement. But I do want one bomb cutter into tn/oh valley with single digit cad in place lol

I'm wondering if the models won't have an accurate idea of next weekend until yesterday's storm is out of the picture.  Also, the GFS might just be waiting until 48 before game time like on Jan 3rd.  

Ops are showing us that it's active, fast flow, and cold around. The time to jump on a solution is when everything downstream is out of the way and ops can focus on the same shortwave. Last few days had some seemingly similar solutions but the snow came from different digital shortwaves. Once 2 ops show snow the same way from the same shortwave, it's tracking time. Unfortunately it's prob not going to happen outside of 4 day or so leads
