PSA: The NWS always appreciates observations, especially detailed observations that everyone on here is capable of giving.  That can be done thru Twitter, as they often set up a feed for that, or the mPing app.  That can include final snowfall amounts, when the snow starts/stops, precip type, dew point, etc This helps them with short term forecasts as well as future forecasts as they can learn from them.  A few years ago they had a freezing rain advisory for Leavenworth, but I notified

I think it sort feels wrong not to have a rip roaring jet stream and heavy rain for a least a little while in the winter.   I would not want it all winter but once in awhile is nice for variety.   We really are due and it will probably lead to another different and maybe more favorable pattern for cold and snow.  

Ok, seriously dude. WHO are you and where the F*** is Tim? 

Ensure his safe return to us and we'll give you two years of snow for PDX/Willamette Valley south.

Deal?

We continue to have gently wafting snowflakes all morning here in Lynnwood, which allows for one of my all-time favorite hobbies.😍❄️

Picked up about another inch this evening. Some of the roads are starting to get some legitimate snow banks. Also, noticing more cars nearly completely covered

Deal.

I just don't think it feels like winter without a few periods of heavy rain.   I think I have been in the PNW too long now.

Thank God for Day 16 to renew our hopes. Could you imagine if the GFS only ran out to Day 10? We would virtually never see a Cold and SNOWY! map again.

00z ECMWF in 6 hours 14 minutes

Perfect time to get some shut eyes in before the run!

18Z ECMWF... basically no change at 66 hours.   I think it has the first part of this evolution locked down now.    And the 18Z GFS was still not as deep as the ECMWF so the changes on that run were probably just heading toward getting to the ECMWF solution at this point.

Total snow through Sunday afternoon per 18Z ECMWF.    

At 4 p.m. on Sunday there is a decent SW wind up to about Everett and then very little wind from Everett to Mt Vernon and then a NE wind up around Whatcom County.   This is similar to previous runs.

Seahawks win tonight means the 00z runs will deliver later.

That is pretty depressing... because there is almost zero chance of that happening.

It’s an important prime time game at home. I give us a better chance based solely on that reason. We have a good history with games like these.

I hardly had any last summer.  I credit the April snow.

We had three drunk hornets fall out of our Christmas tree this year within the first 24 hours of it being in the house. My wife was not pleased.

GEFS agreeing with the OP on a jet extension later on.

Earlier this week it looked like an endless death ridge on the long range ensembles.    Wish the weeklies didn't have the death won't for the next 6 weeks, but maybe the next one wont.

That's a NorEaster producer.  Good to see the east coast getting somethin with that pattern as well, lol.

id say its at least a half notch better than 12z. Need another ~two notches over the next 24 hours probably.

What if the 00Z run notches back?   Then we have to start all over.  😀

Every ECMWF run today has pushed the colder 850s further and further south.  The 18z run gets cold well down into NW OR.  This is pretty real guys.
