PNW March 2023 Weather Discussion (2012 Redux)

[snow_wizard]

And SEA begins March with a nice phat -8 departure.  Amazing that we have at least another week of cold to go.

[snow_wizard]

It appears the GOA ridge is trying to make a comeback at the end of GFS run after a brief collapse.

[snow_wizard]

The precip deficits are actually starting to become considerable for Seattle.  It will be interesting to see if that continues this month.

Well dang, rain/snow mix here currently.

The ECMWF is even more bullish for Friday night than previous runs.  The numbers seem to be cold enough if precip intensity is decent.

Pretty cold air mass.  It has dropped to 37 here, but precip is pretty light.

Maybe we'll get the precip intensity this time.  Slightly different situation than Tuesday.

[Cascadia_Wx]

Nice signal developing for a potentially wetter pattern mid month on the 00z GEFS.

I am sure this will trend to mossman after his convergence zone finishes

Yea I’m not holding my breath. Within 24 hours it will be confined to Mossman and Ludicrous.

[snow_wizard]

The ECMWF is showing a remarkably cold weekend coming up.  Could be interesting.

The good thing about this one is no surface low moves inland to cause a south wind burst.

I’m mildly intrigued. If we got what the Euro showed this week is salvaged. 

[TT-SEA]

ECMWF is strange... it also shows another significant band of snow in the middle of the day on Wednesday with temps in the low 40s as a ridge is building in. 

Snow that falls Wednesday afternoon and temps at 4 p.m. that day... ECMWF is acting like the GFS.    This doesn't compute.

[Rubus Leucodermis]

You can tell Michael Snyder does not have an account on this forum because of the lack of posts calling people out for using the term “graupel.”

That is actually close to 60 in places.

[MossMan]

Currently have some weird chunky icy stuff falling from the sky. 35.8 degrees and windy as well.

Just had a snow shower, no rain just snow! 34 degrees.  Probably will get a few inches tonight by looking at radar.

A fair amount of that is at night though.

The first third of March has been known to deliver the goods from time to time.

Hope this wind doesn’t kill my snowpack.

So close yet so far away!

Last thing I expected was to wake up to a thunderstorm at 330AM in early March. Gonna be one of those years I think.

[ShawniganLake]

Precip is trying to change to snow here.  Sticking snow level is around 1000 ft.

Actually none of what was shown on the map was at night on Wednesday.   The 00Z ECMWF showed 3-4 inches of snow in the Seattle area from 1-4 p.m. that day with temps in the low 40s and still in the low 40s at 4 p.m.   Very strange for the ECMWF.

Looks like just above 1,000 feet out here.    There is a trace of slush on our deck so there must be have been some snow mixed in last night.   Currently 36 degrees with light rain and windy.  

[MillCreekMike]

Lots of windshield splats on the way down to Edmonds this morning 

[SilverFallsAndrew]

Looks like a dusting this morning and some light snow falling. 32 degrees. Moisture a bit sparse though.

We ended up with just a coating. Looks like there was maybe 3” at around 1000ft. 

[MR.SNOWMIZER]

Snowing hard

 About 1 inch new.

[MR.SNOWMIZER]

It's been  snowing since 2 am but just started sticking couple hrs ago.

[TacomaWx]

Where is the 06z euro TIM

[TacomaWx]

Low of 37 in Tacoma this morning…39 now and raining with 0.08” since midnight. Positive splat tests all the way from Tacoma to Redmond on the drive up here. 

[jakerepp]

Looks like the snow level was down 1500-2000 feet in some spots last night.

What a crazy, active week its been in the western US the last week and a half or so.
