My basic 2 cents.
Looking at the GFS perturbations, 11 out of the 20 have blocking South of Greenland between 144 + 180.
A few have a similar solution to the 00z GFS, with a decent cold spell up to between +144 & +220, but no blocking setting up and long term prospects not looking so good.
Some have the initial cold glancing us, but then blocking does setup, so long term things look yummy.
UKMO is hard to know where it would go, especially for me! I personally don't pay much attention to the raw output anyway, I'll let Exeter do the talking. The raw UKMO between +96 & +144 never seem to be great, it held onto the December ghost Easterly for too long.
Now we wait on the ECM,
Anyone who says there is not much snow potential is talking rubbish.
Anyone who says it is more likely that we get a good cold spell is also talking rubbish.
Just enjoy there being some interesting charts to discuss!
