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.
This artic front has been modeled for days since last week, this means business going to bring Christmas in with a bang both a lot of rain and maybe some snow on the backside.
