I woke up at 1:30 and it was snowing and 34 with a dusting.  Currently 35 and melting with the wind roaring. Looks like maybe a half inch on the grass. 

Only a dusting fell by 1:30am? That’s crazy we probably had 3/4 to almost 1” here by that time. We didn’t get much accumulation after about 2:30-3:00am roughly. I believe the gfs and euro run’s yesterday afternoon had us at 1.2-1.4” so it was very close to being accurate atleast here. Haven’t been down to the waterfront but I’d guess they had less than half what I got.

Woke up to about an inch of snow in Lynnwood, and to 2 trucks plowing SLUSH in the parking lot at the high school across the street for over an hour.🙄 Sounded like airplanes continually taking off. What a ridiculous waste of money, time, and sleep!

But...looks pretty out there. I know it won't last long. Can't wait for Round #2, whenever that is!!😃

1” here in north Seattle. It did get down to freezing as well.

Hopeful Tuesday brings a little more.

I hope Tuesday ends up being a nice surprise for those to my south.

Then I want to score again in early March, so I can add another month to my list of months with measurable snow this season!

I got up twice in the night. Saw it snowing hard at 11:30 or so and was excited. But at 3:30 it had stopped and looked to be melting 😔 I'm guessing we had about an inch before the melting started with the south wind. This is all that's left.

Topped out at an inch (I was in the grey, the stupid Euro was right) total is down a bit since 4:30am as we have some meltage. But I did add to my deck snowbank before it melted more off the deck. 

Currently 33.3 degrees. The lowest it got was 32.5.

Elevation 580’ Location a few miles east of I-5 on the Snohomish Co side of the Snohomish/Skagit border. I love snow/cold AND sun/warmth!

12Z GFS is farther north on Tuesday than previous runs and pretty crazy for the Seattle area.

Sure hope not. I would sure like to score for once. In other news radar has filled back and its dumping again.

12Z GEM for the Tuesday system... the action starts in the Seattle area around 5 a.m. Tuesday so this covers the event.

Man my area has sure been moisture starved when it comes to snowfall compared to what I typically get…Wrong trajectory with these systems.

Gem has been pretty stingy on precip compared to the other models. Atleast here it underdid the precip. 

Oddly enough it has been opposite here.   A couple days ago it was showing about foot of snow here last night but the precip totals went down each run leading up to the event.    Might be a terrain issue out here.

Nothing to write home about here.  Stayed at 34 all night, and went back and forth between wet snow and rain.  The deck is clear, the ground is covered with slush.

Went for a morning drive few miles west of town into the hills. Pretty amazing to see the transition zone. Nothing at my house at 400' but once I hit 550-600 snow was lightly dusting the ground then once at 800' it was complete white out and few inches at least. Really shows how marginal these events can be and the difference of just a few degrees, elevation, time of day and precipitation intensity makes all the difference. 

People who are not weather nerds need to learn this lol.

The GFS is just an awful model for snow totals.  I actually started to think the more it showed the better chance for snow.  Not true.  That model's output for snowfall is not much better than a random generator.  34 after a low of 32.7

It is often the first model to pick up on an impending arctic outflow event, and it is useful to back up the Euro (a modelled outcome with a Euro/GFS consensus being much more likely to verify than one where the Euro stands alone), but as a general-purpose forecasting tool its accuracy often leaves a lot to be desired. I would never get psyched about a snow event that the GFS alone was calling for.

There was an insane steep gradient in the first 100 m of elevation here, from a slushy inch on the beaches to over a foot in the higher hills. Living near a ridge top really helped me score last night.

Wow... that is amazing.    You have more in Bellevue than I do out here.   And it looks like you aren't getting this roaring SW wind we have out here because you have snow on the trees still.    What is your elevation there?

I’m up at 1170’ top of hill just NW of cougar mountain. Was pretty brisk SW wind last nite
