Friday night and Saturday 

Still looking good, but gotta see it to believe it. Only about 42 hours to go! 

[TT-SEA]

12Z NAM keeps the precip mostly to the west and south of King County... but goes nuts in the Portland area.

[MR.SNOWMIZER]

Just dumping now, temp down to 32.0. Wrf was right, it showed a couple inches of snow here this morning.

Every model shows a range of 4.5 to 10 inches here. It's going to happen. 

[TacomaWx]

IF (Big if) the euro actually verifies it would probably be the biggest snow event we’ve had in Tacoma since March 2002. We’ve had 1/2” snow accumulations in 2009, 2012 and 2019…but I haven’t recorded 1” or more since I’ve been keeping weather records in March. Pretty weird considering we had 3” in April 2008.

Lots of precip, cold air mass, and offshore flow by Friday night and Saturday... all signs are good for the Hood Canal and Kitsap Peninsula.

Going to depend where the low moves down the coast, if we are in the sweet spot of the showers we could get close to the 10 inch mark some models have shown. 5-6 is realistic. 

[TT-SEA]

Models were right about the low precip amounts over King County with this current system.    SEA is only at .11 so far and North Bend is at .20 and the back edge is moving into the area.    Next up is a c-zone along the King/Snohomish county line through this evening.    That usually means a roaring SW wind in my area.  

[SilverFallsAndrew]

What’s the total snow on the EURO?

I’m having a hard time imagining we get more than 1/2” considering that’s usually what these early March snows have produced over the years but we will see. This will most likely be our last realistic chance at accumulating snowfall this cold season…so hopefully it overperforms like a mofo. Looks amazing out there!

Wow, gonna be about a -17 departure today. Rainfall at the closest gauge totaled .8'' over the last 24 hours and nearly 6'' on the year so far.

Heavy snow now, and time to leave for work… 

[TT-SEA]

12Z ICON show the Hood Canal snow but not much elsewhere.

Looks like my doughnut hole is now a happy hole.  Fingers crossed.

[TT-SEA]

12Z GFS just buries the Hood Canal area on Friday night and Saturday but keeps the precip mostly to the west of King County... similar to the ICON.

[MossMan]

All snow now, 34.8 degrees 

[MR.SNOWMIZER]

Gfs shows steady snow here friday night from around 10pm to 10am, The sweet time looks to be between 4amand 10am. Perfect timing again.

This is going to be a major snow event out here it looks like. 4-12 inches will be the range depending on location out here. Further west the better for the most part. Looks like i'm in the 8-10 zone but could be much more or less also. Tricky pattern to nail down amounts.

[Iceresistance]

Y'all getting snow up there? You deserve it from the last 2 years that I got dumped instead!

All thanks to the low sinking south offshore which results in offshore flow and tons of upslope precip against the Olympics and cold air damming.   On the other end of the spectrum... the offshore flow will likely have a significant drying influence west of the Cascades.

Trying to slush up in spots on the deck. 

[SouthHillFrosty]

The Euro has a half a foot of snow for the swamp….. not believable 

[TT-SEA]

Sure sign of c-zone forming is when Bellingham clears out quickly after a frontal passage.

Also problematic is half of that falls before 4 p.m. tomorrow and there is a strong SSW wind from now until late tomorrow afternoon.    Doesn't make sense.

The wind issue is not a problem for you tomorrow morning... you are in the c-zone area with lighter wind while its very windy to your north and south.     

[MossMan]

A little more snowy up there this morning than when I was up there at this time yesterday. 

[Anti Marine Layer]

Portland forecast is a broken record that may break some records

[T-Town]

The rain is a little chunky here. 39 degrees. 

[Timmy Supercell]

March 2012 was pretty huge for K-Falls, the cards would have to line up perfect for another repeat. 

15.2" on my personal notes, with my 2nd best March being around 9" in 2019. It doesn't seem too difficult to have a cool March, but snowfall can really be anywhere year to year.

[TT-SEA]

12Z GEM shows the Hood Canal snow as well... but shows only very light precip around the Seattle area with the offshore flow.

[Jakewestsalem]

Trying to snow in Stayton. Was 40f with stiff south winds when I got here at 530am.

37 now

[MillCreekMike]

It snowed on March 8th 2019 and it was 70 degrees and sunny on March 20th 2019. Things can change quickly when we get to this time of year.

Yeah, If IIRC we went from 38/29 on 3/8 to 76/44 on 3/19 or 3/20. Pretty wild swing. 

[snow maniac]

Oh yeah, looking more into it we actually hit 80 up here on 3/19. Crazy swing in less than two weeks.

A friend just shared this on Fb. Pretty incredible winter down there.

[AlTahoe]

Here's a fun little youtube video recapping the blizzard. Some amazing footage
