I was just up at the parking area. They are packed! 5 years ago no people used that area for the most part. Not like now anyway. I recognize that area. 

I just made it to the top!

FWIW... EPS and control run also shifting west.  The control run goes to a massive GOA trough after day 10.

Here is run-to-run change on the EPS in the long range...

Also Euro Control goes crazy

Might be some serious terrain bleed there... because the 500mb pattern on the control run could not be more different than its 00Z run.

Ended up with some snow here.  Kind of alternating between rain and snow.  Still only 33 though.

If memory serves the ECMWF has a long known bias of kicking too much energy SW underneath a block like the one coming up.  Not too worried about this run.

Light rain and 40 here.

This is a pretty rare case where inversionary cold air leftover here made a difference with precip type.

I would have been shocked if everything stayed perfect right up to when the possible good pattern sets up.  That NEVER happens.

Pretty good chance the ECMWF is too aggressive with the warming in King County later today.  It's been known to do that in cases like this.

True... no way to know yet.   Maybe the westward shift is real and we are just starting to see it in the models now or maybe everything will shift east again.    The latter would be a compromise with the GFS.

About 37ºF here near U-Village and I have some flakes mixing in! 😍❄️ 

Was looking outside seeing some chunky rain, and was very surprised as I didn't think it was that cold. Now it's solidly a rain/snow mix. Very pleasant surprise!

Druncle must have killed 2/5ths of vodka this morning or something 2 feet in places in the Florida panhandle WTF?! Obviously not going to happen but the fact it’s even spitting something out as ridiculous as this.

Good signal on the 12z EPS for a longish period of below normal temps in the mid to long range. Obviously details are still up in the air at this point.

I’d like to see more really cold members, but that’s the kind of signal we were seeing prior to February 2019.
