This system that comes in behind the Christmas storm kinda reminds me of that system that happened on February 8th of this year

What happened on the 18z euro for the storm after the Christmas storm that’s the one I’m watching looks like it has more potential

We have a train of systems coming with cold air at the door step. We have to get one with this pattern.

18z doesn’t go out that far.
There should be more discussion about the Euro and the severe threat it has consistently shown east of the Apps Christmas Eve. 850mb winds 70-80 knots with a screaming 120 knot jet overtop. Surface dewpoints in the 60’s, backing SE surface winds 10-20 mph, 70 knots of bulk shear... if there is even a hint of instability it’s not going to be good.

Good they had enough snow lmao
Fortunately this has, to my pleasant surprise, turned out to be anything but an ostrich December, I will always be content with a winter month like this. This is likely headed for our coldest Dec since 2010! I had still another great walk this evening with 50 F and dewpoint near 40.
Trivia: our 3 coldest months since 1982 and by a good margin at that have all been in Dec: 2010, 2000, and 1989!
In my area, averages will fall for another 2 weeks albeit more slowly than in recent weeks. We're just now entering the coldest half per averages, which runs from December 19th through February 2nd. Interestingly enough, however, our peak in wintry precip based on very longterm averages has actually been a good bit past the end of this coldest climo period, in mid Feb! I think that one reason for this is that the upper atmosphere apparently doesn't hit its coldest until around then, which may also mean the furthest south average storm track. Also, it averages a bit stormier/wetter in Feb vs Dec/Jan.
Even though Feb averages are the warmest of all three winter months (although not by that much), it can get as cold as midwinter records as late as mid-Feb. A good reason why is that the Arctic's average coldest is not til ~Feb 25th.

Believe it or not, CHA is still just slight above normal for mean temps. Decembers have been rough around here since 2010. We've seen some small snows below .5, but nothing amazing. Missed several to the south in the past decade. Not crying, lol. Chattanooga has done better with snow in the 2010-2020 range, than the previous decade. That was a heartbreaker decade around here.

Yeah the lag in our snow climo vs temps is something I’ve discussed in here previously, it has to do with the total snow cover volume and sea ice extent in the NH reaching its maximum in late winter plus the oceans are cooler in Feb than Dec. These 2 effects outweigh any contribution from increased solar insolation. Our higher averages plus higher snow climo in Feb vs Dec also means that’s there’s a lot more variability at that time of the year than early winter
-NAO developing on the Euro around D10. That's good to see. Liked the 0z GFS in the LR. 6z was less impressive, but hey, it's the LR. Still no fantasy storms.
What till new year or after. Jumpin January is going to be fun.

I want real snow instead of fantasy snow. But it is discouraging not to have any bites at all with a decent pattern showing up. It's been a recurring theme the past two years with nothing showing up. The last two years the pattern was so bad it wasn't surprising. But this year so far I figured we'd be seeing more hope than we see now.

Just posting the 00z ensemble teleconnections for the euro. However...all major ensemble suits have a -AO and -NAO. The catch will be the EPO and PNA which look naturalish...
