Even though snow started as a mix the snow now is MUCH dryer than the snow Tuesday night. That was really wet and heavy. 

Great sign. It’s amazing how often you start as a 34 degree mix there and wet bulb down to just under 32 with heavy snow.

[SouthHillFrosty]

Temp is 33 with a dew point of 28

[SnowySeeker50]

Currently 34, DP 31. Looks like some light snow falling.

38 with rain here. On to the next. 

Low is sinking south. You'll see colder temps later as flow turns more NE, and probably a switchover at some point. Just gotta hope precip hangs on long enough once that happens.

PDX ESE wind at a brisk 21 mph 

That wind is going to get quite cold by tomorrow.  Some serious cold air filtering down through Centra WA.

Not true.  Cold air damming should be helping Shelton a whole lot more.  Probably just need the entire column to cool still.

I'm talking about outflow from the Cascades, which can be just as important as cold air damming against the Olympics in a scenario like this.

That's somewhat encouraging for us I suppose.  This cold air is "fresh" enough that it might still have some depth here.

34 in Shelton and 33 in Bremerton but both still reporting rain. Not the greatest sign but could change with heavier precip. Temps will be close tonight.

Michael Snyder said it’s snowing at his house

The outflow is often too shallow in the southern part of the outflow zone like I'm in.  As you go north it usually becomes deeper.

[Deweydog]

Down to 38 in The Dalles…

[Requiem]

This matters not... but the NAM significantly increased upper level support for strong surface winds through the Gorge. Minute detail, but may mean that we'll see some strong gusts surface in locations.

Great. So instead of just giving up and relaxing on the couch, now I’ll be getting up to check the streetlight every ten minutes.  

[snow maniac]

Starting to change over now.

Shelton switched to snow for a bit then back to rain.  It's close now.

You're gonna get thunder snow again. That will the cherry on top of your bday snow cake.

Have a really hard time believing it’ll snow here tonight with a temp of 37 and a DP of 34.

Our couch and TV in the family room downstairs is next to the windows and we have two flood lights above those windows.  So I can sit on the couch and watch TV and see outside from behind the flood lights (always best) without even turning my head. 

[TT-SEA]

Also have to make sure lights are off inside for maximum viewing of outside!

You have a weather weenie cave. That’s awesome. 

[Skagit Weather]

I'll take whatever the 00z 12km NAM is smoking. It shows more than 3" up here tonight. Of course the 3km NAM shows nothing, but I'm going to ignore that for the time being because higher resolution is clearly worse, right?

3km NAM showed a couple inches of snow here on Tuesday night... ended up with about a foot.    The 3km NAM definitely underestimates precip.

Nice view except for the pain of seeing the Utes instead of the Ducks.

It would be fun to watch USC destroy the Ducks.

It was probably the surface pressure gradient having too much of a southerly component to it.  Once the Fraser outflow gets cut off Bellingham skyrockets easily.  Then of course the next day the moisture was too far south.

Low placement was a big factor. With the low centered rather closely to your NW over northern Vancouver Island upon its approach, you were at an unfortunate trajectory to really maximize the downsloping southeasterlies off of the Chuckanuts that Bellingham proper is extremely prone to. It was a relatively shallow wind field though, so Lynden and places north of Pole Road never scoured out until the low had passed.

I think the same localized downslope warming occurred in some other parts of NW WA near the Cascades, including Winterdog's area, while other places a little further west benefitted from the ESE flow. 

Thank you both! I really appreciate the info. If you dont mind, I'm curious what the difference was from Randy south? Was there a second low east of the central/south sound that maintained easterly flow for the region? Sorry I dont remember how the maps looked that night I was busy complaining about the 36 degree rain to my girlfriend lol. 

[SouthHillFrosty]

Light snow currently!!!!

That Williams guy is great, but maybe Nix wouldn't be limping around this evening.  We will never know.

Currently 37/31 dp here. Not sure if I’ll get snow tonight.

Williams is basically a RB playing QB... he is pretty fun to watch.

All those spring days when the sun is shining there on God's country while its dark and gloomy in every direction.

[Fircrest]

37 and raining.  Don't think it's going to snow here tonight.

[Margaritaville]

Reporting from Shelton. The 34 rain is now snow

I can't root for anyone playing for that program.  Would be nice to see the Hawks go after him in the draft though.  Could happen............

[MR.SNOWMIZER]

Pounding snow pretty hard now. I set a snow measure board outside at 6:40 so I can check it in 1 hr. We are getting well over 1 inch per hr rate right now.

[MR.SNOWMIZER]

The flakes are 2 inches across lol. Wow. It has been dumping these huge flakes for about 15 minutes now.
