Models keep digging the trough in the west. It's going to be hard to get snow in the east with that even with a negative NAO.
Hopefully the models are wrong and they show colder outcomes in future runs.
Snowy gfs run for Christmas for SNE. CMC also has a storm along with the euro but it's further north. The NAO will be negative . I wouldn't be shocked to see that storm shift south but if it doesn't, the pattern gets better afterwards.
Mjo on the euro is now starting to move towards 8 but slowly. It was mostly stuck near 6/7
