Mid month on the 12z GFS has an interesting evolution. It is a long way away but that is when I think PSUHoffman was also talking about (with the Mag and Showme posts today) the pattern kicking in ripe through February.
GFS model has backed off a bit for SCPA on the ice threat 0z and 6z both show the high to the north being pushed out quicker. We will see what today brings.
