Can you get a similar view of the Euro? (if/when it is available)?

Not without precedent, but these are some BIG swings d10-15. Good trends at 12z. Newer runs are on the left. 12z GFS vs 6z GFS 5d 500 anomaly map. 12z Euro vs 0z Euro. The Euro moved from an eastern trough to a western trough. Now, this is just deterministic stuff. So far, ensembles look pretty steady.

12Z OP GFS (yeah, I know GFS, 300+ hours out, lowest skill score of the major globals) persists in uncorking western Canada / High Arctic cold flow into the U.S. in the lead up to Christmas. Details and placement to be confirmed but the point is that it's too early to be dismissive of significant cold lasting into Christmas week. GFS probably extreme but I'm not planning on a Christmas torch this year. The 12Z GFS surface pattern out to the end of the run is something we've not seen in quite a while with high pressure stretching from the high Arctic southeastward into the central U.S. Time will tell and something interesting to watch. In the meantime pattern is cold and dry with precipitation being measured in the a couple of tenths at best over the next 7 days or so. I just can't get too invested in little nickle and dime snow events. Unless it falls on Christmas Eve.

I just hope its right but the models have struggled greatly within this domain.

Grass turning white

I’ve been looking at that map for more than 5 years now.

GFS and Euro couldnt look more different for Christmas Eve

For the first time, mostly snow now

Changing over earlier than expected in norfolk. Good sign for you

That’s a good visual of how the arctic jet strengthens from Siberia to AK/N Canada as that WPO block strengthens. In addition, the stronger WPO block helps force that vortex down south of Aleutians which helps pump the PNA ridge…I think it was @Typhoon Tip who talks about their inverse correlation with a small lag.

Nothing on roads or grass, but my 3rd cartopper

I really had not looked that far out as we have had a few events in the short term here and another one tomorrow night into weds.

27/3 now. Arctic airmass. good for the utility companies and ski resorts up north. Otherwise useless

You changed over earlier than expected. good sign for our NC friend

Didn't last long and ended as a mix. It was pretty heavy for a few minutes. 0.05" from it melted in gauge in about 20 minutes.

33 and larger flakes now.

Down to 35F! Flakes getting bigger too!

I guess this is the feature to watch over the next day or two (Coming out of the Aleutians). How this evolves in the next 48 hours will likely tell us whether the ridge will amplify or not

Precipitation shield is really filling in nicely now from the south. Looks like the Richmond metro is about to get a heavy band.

Deck lowering and flattening out, heaviest rain of the day despite nothing showing on radar. Hoping for some last minute magic.

A lot of these solutions are actually in a historically good spot for D6. The key is the trend…if we a slowly amp that ridge a little more, could be a solid event for a chunk of New England…esp southeastern 2/3rds which would include your area. What we don’t want is to see the trend in the ridge regress again.

Flurries now

CC line directly overhead now and just like that snow is mixing back in. 37.9 so I doubt we get low enough for much to stick, sadly

Yep, temp and rates seems to have found a sweeter spot downtown now. Awaiting, the HR liability email, sending folks home soon.

how many inches does euro show for white plains, ny
