PNW March 2023 Weather Discussion (2012 Redux)


Requiem

Recommended Posts

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.

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

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!

A fair amount of that is at night though.

ready for some never before seen march action.

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

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

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.

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

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.

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

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.

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.

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

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.

We come from the land of the ice and snow.

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.

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!
