Just woke up. Good morning. I am sure you noticed the 6z GFS nudged the track of the low further east FV3 a bit and a nice reload. 6z ICON snowy. NAM nudged east too. Also importantly note where the arctic trough digs off BC it's hugging a bit closer to the coast line instead of further out that should keep the air mass a bit colder. I also noticed that trend last night on 00z GFS, FV3, EURO of holding the arctic trough further southwest wasn't there on 6z. Don't rule out 12z runs to shift the low a notch east. For PDX metro We have keep an eye on any lows that linger from Tillamook to Newport as Colder air is likely to creep down into the Columbia Basin and those lows will pull in Colder, Drier air. 12z ICON looks to be snowy too. 12z GFS in 5 minutes
