It is a weaker low, but much better track for a localized/PDX, northern Willamette Valley wind storm. PDX-EUG at least -10mb.

Yeah, not looking like a regional blow anyways at this point (need an offshore, SW to NNE trajectory for that). It'll likely be a localized high wind event relegated to within 50-75 miles of the track.

00z GFS actually shows a pretty potent event, quite rapid deepening as it heads ashore. 

This one looks like a potential analog, FWIW

Don't make any judgements off this run. This is just demonstrating how finicky this whole situation is. Don't be surprised if this is a flukey run, or if the Euro sticks to its guns. There will be a lot of wobbling in potential storm strength, track placement, timing. We likely won't know anything for certain for another 36 hours as models handle this energy ejection from the trough off the east Asian coast.

Face value GFS looks quite good for a W. Valley special— we’ll see how models play around with strength.

I know call me crazy but I think the models might just be struggling with low placement and strength...

No, its set in stone. This will be a non event and the only maps we should be posting are only a few hours out. Also, snow this winter is canceled.

Just one run, but not looking good. Also about time to start mentioning it’s been a pretty dry month so far in the willamette valley.

I like tonight's GFS, but then again I'm looking for different things than a lot of people on here.  To me the recurring blocking over the NE is a very big deal.  I kind of like Friday's low on this run.  Looks like a pretty chilly track for the Puget Sound area.  Speaking of chilly....thicknesses fall below 528 for SEA a few different times over the next 10 days.

Just caught up with this thread. IMO the mood swings after each model run warrant the issuance of weenie tags.

Maybe I'm totally wrong here but I do like how models are starting to intensify the low as it hits land rather than gradually weakening it after a stronger peak...
