We would need to sort out the pacific before the East Coast gets chances for big snowstorms. I dislike that +EPO a lot. It's more likely mid-late January will offer that -WPO/-EPO/-AO/+PNA combination.
It's about that timeframe where you start to see some ensemble members show fantasy storms for great patterns. And they are starting to show that. There are lots of big hits. The ensembles have been lighting up.
