The writing is on the wall here. January is toast. I posted last week that when GSP gets an inch or more in December January was a shutout in all but 10-11 and 17-18. And 10-11 was late Dec and early Jan and was from the same pattern, so not really the same.
Feb is not lost but the two recent years the Pac jet got this strong it ruined the whole winter. 11-12 and 16-17.
If the 0Z EPS is even close at the end of it's run January is toast. You don't transition from that crap to a decent pattern quickly.
