We'll give Flatiron a chance to regain some traction as Santa might bring him a big sack of forum street cred if he can pick the right digits.

 

SEA/PDX

 

Friday through Monday.

 

Highs and lows.

 

Tie breaker will be the Standard and Poor's closing bell number for 2017.

This round of cold snap model riding has dumbfounded and flustered me like no other.  The whole upper-level pattern forecast has been teetering "on the edge" for more than a week now and it STILL can't decide how much arctic air comes west of the Rockies. 

To sprinkle a bit of comic relief, all this wild flip-flopping seems to have broken the GEFS weather ensemble charts at the site I use.  Haven't been able to get any new ones since 18z Sunday.

 

About all we can say for sure is that the Basin at least gets a shot of medium-cold air at the end of the week.  Some of that will come through the Columbia River Gorge to chill the Portland area a bit.  Everything else is still a total crapshoot.  -_- :ph34r: :o
