And with the 1st of January projected to be very warm, they are going with a big pattern change for the 2nd half of the month:

 

PNA has been negative every day this Winter since Dec 1st. LR models have it going positive for the 2nd half of January:

If the CPC is right, it could actually get very cold Jan 20-30. 

I guess that's our 1985 look.   Now we just need the moisture.

  Latest wpc for the Jan 4th event..

0Z NAM ticked south...no dice.  Wishing all of you a Healthy and Happy 2026!!!!  And a Blizzard or Two!!!

[Ephesians2]

It's within striking distance for DC south, we just need temperatures to trend down a few degrees

Nam may have ticked south, but based on 500mb vort it took one step closer to the euro. Northern stream vort is sharper and more south. The ss vort shifted south too, but if it stays north like 18z, then there will be more interaction.

18z RGEM was north?

Thank God we have something to track. Even though I knew this early-January period might not work out, I was still kinda getting a little bit restless.

Wasn’t Jan 85 bone dry?

[bncho]

ICON is much better. More north. 18z vs 0z down below.

Some models go north some go south. 72ish hours out. Sad

Yes, it was here at least.

0z GFS continues to keep the NS and SS energy completely separated with no sharpness to the NS shortwave, so no dice.

Quite the battle between the Euro and the GFS as to the outcome. Its either a nothing burger or a light 1-3" event for at least parts of the region.

Sorta, 2.27", with 0.63" of that falling on the last day of the month. 4.5" of snow, but boy was it cold! Especially on 1/21, -19 that morning, a -4.2 for the month.

Going to lean on the nothing burger

Up your way, probably a good bet regardless of which model is more correct.

Happy New Years from the 0z GFS
