Echoes approaching.  Not sure this first band will be enough to moisten things up.

 

 

Temp 31, DP 24

That is a pretty good temp/dewpoint combo there for snow.   Not real dry... and below freezing.

36/25 at SEA

 

38/29 at UW

 

38/26 here... but its 29 down in North Bend so the east wind must have died down completely in the valley.

 

 

With the system last week we started with dewpoints in the teens and it was too dry... mid to upper 20s in much better.

[El_Nina]

This first band has been all ZR here so far.

[FroYoBro]

Mix of rain and sleet here, but it is above freezing already.

 

 

LET THE SNOWSTORM BEGIN.

[Guest CulverJosh]

Yep. Zr here as well. As per usual Mark nailed it as he didnt think the first batch would be much. We will get a noon or so 38 degree steady snow that wont stick according to him. D****T.

We can already call this a bust.

Naw. What is happening is what was forecast. Its well into March. We know better.

[Jesse]

Light snow here, with a dusting on all surfaces. 31.

STFU

[Guest CulverJosh]

I believe it. Looks like snow in vancouver.

[SilverFallsAndrew]

Eventually most areas will transition back to snow as the cooler air aloft works in. If people will remember back about 12 hours ago I was insistent that areas away from the gorge influence such as the south and probably west metro would be rain or ZR this morning. Of course no one wanted to believe this, but I was right. Won't be much precip this morning, but over on the east side it will continue a bit longer so folks like Jesse could see a nice dusting. 

[SilverFallsAndrew]

My wife said there was already a car in the ditch on her way home from work this morning. Currently cloudy and 32, but it appears there was some light freezing rain when this band moved through and roads were very slick.

[SilverFallsAndrew]

THANK YOU WISE WHETHER GOD

 

I wrote that post JUST FOR YOU. 

 

But honestly looking at the radar I think you are in a good spot.

ya today seems pretty even temp wise throughout the Seattle area due to the clouds and system coming in. What was the difference yesterday?

[Requiem]

Whether we see flakes falling tomorrow or not, amazing winter overall. Everyone saw impressive snow, and I use the term "everyone" just like how folks in PDX refer to snow in Washington

Yeah, like everyone got snow in 2016-2017 (why can’t we have a repeat of that season?)

I believed you, I think there was really only one main person who disagreed with you.

 

Nice hole of moisture over Washington County right now.

He was saying there would be rain or zr everywhere, including gorge influenced locations. That’s called trolling for those of you following along at home.

 

Obviously I was correct to disagree since it’s snowing here now.

I was talking about MountScott. I also don’t think Andrew was trolling.

Well. Unfortunately the warm nose turned into a warm blanket this morning. I shouldve known when ski bowl was 5 degrees warmer up top as opposed to the base. happens.

[Requiem]

That’s weird, it’s mostly snow here and I’m on basically the same elevation as you are.

Always creeps up the eastside. My dad at 800' between OC and Mollala always has rain in these scenarios.

It is snow here on the west end of the metro, just flurries right now. Precip type is also snow in downtown. Basically everywhere but south metro is able to support snow even without any wetbulbing. 

 

The usual theme of no precip in WA county is the bigger issue here.

[FroYoBro]

Pretty normal for warmer air to ride up east along the cascades creating that warm nose. Cold air banks better to the west where you are, so the cold air is a bit deeper there.

[Guest CulverJosh]

And to add to that. We all know OC/Gladstone/milwaukie/clackamas are horrible producers in outflow setups. Ad Mark has stated before, somehow the cutoff always happens right around Foster Rd or so in the 205 corridor. I miss out by a few miles from big accumulations quite often. I make up for it kind of like Andrew does. Once the upper levels cool.

Fascinating (and equal parts frustrating). Maybe tonight is a better chance for you guys.

See above.

[El_Nina]

Snow is beginning to mix in.

[TacomaWaWx]

Some pictures of snow up in San Juan’s from yesterday up about 2400’ up! Somewhere between 2 and 3ft deep depending on the spot.

[Omegaraptor]

According to averages Washington County is actually slightly wetter than PDX. Wonder why it’s the other way around this year.

[El_Nina]

Transition complete. All snow

Lately these systems have been coming from the SE so the dynamics have been better for the east side. Normally we have our lows to our west.

[El_Nina]

Course this lull in precip is coming right as I turn fully to snow.

[Blizzard777]

36*

Dew point 23*

NNW wind 3

Cloudy

 

Low of 33*

100% chance of ash on my forehead and sticking!

[FroYoBro]

Probably would have changed to snow here if I was under a decent band. Seem to be in the middle zone with sleet right here in Tigard. Expecting to at least see snowflakes in the air later today hopefully.

[Jesse]

Dumping in Salmon Creek now.

[MossMan]

30 and cloudy. DP 21.

[El_Nina]

Got a dusting before that last band left. Now looks like 20-30mins of jopokg it doesn't warm much before the next batch moves in.
