Now I am getting a little confused, there are three systems

23, 25, 27th

The 22-23 system just looks like a flat wave, doesn't do much. The 24-25 system is the one the models are keying on the most now. But often, it's the last s/w that comes out, that is bigger storm for us. This setup is different from most others thought, because we don't have any blocking. So all bets are off.

only two systems have sufficient cold air to work with, the 2nd and 3rd ones if we are using the 12z gfs today.

The 2nd one the euro blew up last night for the xmas miracle, somehow keeping the HP anchored over NE with no 50/50 low.

I doubt it shows that today.

The third system needs amplification, which is a dangerous thing to ask for in this pattern

that 3rd threat, if you look at h5, you see a decent ridge out west.. (not great, but decent). roughly hr 132-135.. but then in the next few frames, a pacific s.w tries to undercut that ridging, and flattens it out, and not allowing that southern wave to amplify, hence the offshore solution. Not saying 1 way or another, b/c we know how well the pacific is sampled, but it can go either way there. Either continue to flatten the ridge, or help it. Of course, all dependent on timing.

yup. Just way to much noise right now for the models to sort out with all the energy ejecting from the SW which messes all of them up, not just the euro.

Just looking at the individual ensembles you can see how a few of the member are each keying in on the different waves offering no concensus.

Fun week coming.

No consensus. I think we need to watch the Friday threat first...it's small but could give the north and west burbs some white stuff.

here is a good way to see how that energy is the SW is the player. Check out the 3rd wave setup off the gefs. Some have almost all the energy back in the sw, some have none of it and are amplified, some have a little bit eject and are flat and some have a little bit more and are somewhere between amped and flat and the OP ejects it but doesn't quite get it to bite

It's colder with some light overrunning precipitation at 12z Friday...so instead of 40 F and rain, joshua gets 36 F and rain.

that was always rain, and the euro hecs is gone, shocking

accuweather must send out that euro control garbage to increase its suscriptions
