March 2020 Weather Discussion for the PNW

[Phil]

I like how Tim made sure to get on here and post how it did not snow at his house, how it was above freezing, and how it will be mild next week.

I hear he’s scouting for real estate in Death Valley.

[Jesse]

I'm dying to see what the mins are going to be like.  Maybe WA will have a better shot at that with more clouds in OR.  We shall see.

 

Oregon doesn't look particularly cloudy next week compared to Washington. At least the northern half of Oregon. The airmass just moderates a lot more slowly then stays cooler overall.

[Phil]

Just WOW!

Dendrites.

[Blizzard777]

Feel like I’m in Mosman country! 

[TacomaWaWx]

Certainly a good flow of cold low level air coming down Puget Sound.  Tacoma Narrows and West Point are both well below 40 with fairly strong N winds.  This is some pretty impressive stuff.

Big flakes falling now and 36 degrees I was not expecting this at 11am. Probably will end up with back to back sub 40 highs here really impressive for mid March.

[Jesse]

Light snow has started here again. Not a ton of melting between bands, still just 33 DP 31.

 

Looking like some good enhancement on radar. Judging by the pics/reports from down south things could get fun again for a little while.

[FroYoBro]

This last burst of snow is fun even though the heaviest stuff went right to my east.

 

Huge flakes sticking to most things at this point.

[GHweatherChris]

37 degrees now, but still have light snow falling.

[TT-SEA]

Typical extreme response to someone just looking forward to some nice spring weather... like probably most people in western WA. We actually all want to burn alive!

 

In reality... this is just your anxiousness about the coming warm season being projected on someone thousands of miles away who lives in an area with gorgeous summer weather normally.

[SouthHillFrosty]

Nice moderate snow for the last 15 minutes️

[HighlandExperience]

Holy crap! This is a big case of the east wind here killing me, but helping you immensely.

Puget Sound really missing out

[snow_wizard]

According to the WRF tonight and tomorrow night with both be clear so the potential is there for outstanding low temps both tomorrow and Monday.  Winds might be an issue, but tomorrow night looks great.  With such a dry low level air mass in place records should fall.  I expect a mix of record low max temps and record low mins for today through Monday.  Tuesday morning will probably be quite chilly as well.

[snow_wizard]

Puget Sound really missing out

 

At least we had some yesterday.  This is pretty hit and miss overall.

[FroYoBro]

Wow, the road actually just got covered in snow at 11 am in March. Impressive!

[snow_wizard]

Oregon doesn't look particularly cloudy next week compared to Washington. At least the northern half of Oregon. The airmass just moderates a lot more slowly then stays cooler overall.

 

I don't expect there will be that much difference between the two states.  Low temps are not that reliant on 850s.

[snow_wizard]

The power of continental air!

[SouthHillFrosty]

Perfect time to go cut the lawn

[Omegaraptor]

 

These have to be some of the biggest flakes I’ve ever seen. Including on Mt Hood.

 

This might actually be one of the best snow events since 16-17 here... and it’s mid-March. In just three days it will be in the 60s. Is this western Oregon or eastern Colorado?

[Jesse]

DUMPING now. Some of the heaviest snow and biggest flakes of event.

 

Really getting blown around by an increasingly gusty east wind too.

[Jesse]

This band seemed to really pull in the east wind. Down to 32 DP 29 with gusts 25mph. Snow is sticking to everything but the road too. Some pretty impressive conditions out there for mid March at the moment.

[SilverFallsAndrew]

Officially 0.3" at PDX today.

You’re welcome.

The convergence is definitely enhancing it. It motored through here pretty fast, up there it seems to be re-developing as it interacts with the outflow. Sunny and 36 here. Going to be a crisp couple of days, and loving that we will see more cold nights next week!

[SilverFallsAndrew]

Salem and Eugene into the mid-40s with southerly flow. Interesting set up. PDX could see a very chilly high though today.

[MR.SNOWMIZER]

Awesome dude!!

[James Jones]

Sticking to everything here, even some slushy accumulation on the roads. 

[TT-SEA]

12Z ECMWF shows a bubble of warmth over WA on many days this week... in a sea of western cold.

 

[FroYoBro]

Officially 0.3" at PDX today.

D**n, I thought they would have more than that.

[Jesse]

Salem and Eugene into the mid-40s with southerly flow. Interesting set up. PDX could see a very chilly high though today.

Today’s record MIN MAX of 43 from 2012 seems like pretty low hanging fruit. Although we could get close with any appreciable sun this afternoon.

[Jesse]

Overall the ULL seems a little closer to our area on the 12z Euro next week. Not quite as many warmish days as previous runs.

[ShawniganLake]

Temp has actually dropped from 34 to 32 here under mostly sunny skies over the past hour. Unusual.

I say PDX stays below 40 easily with the east wind now.

Wow!  This time of year that is very hard to do.

Nice! Man do I ever miss that.

Of course that’s what you’re focused on.

 

I only see one bubble of warmth there..and it’s over me.

[Jesse]

Maybe but fairly solid cloud cover much of the day would be a must for that feat, IMO.

[TT-SEA]

Overall the ULL seems a little closer to our area on the 12z Euro next week. Not quite as many warmish days as previous runs.

 

The 12Z ECMWF shows afternoon temps above normal from Salem northward to Vancouver BC every day from Monday onward.    The only exception might be Wednesday south of Portland.  

[TT-SEA]

Of course that’s what you’re focused on.

Yes... I do tend to focus on weather in WA on a weather forum for this area.   

 

I do see now that your bubble is WAY bigger!     But I will still very much enjoy our little bubble.  

[snow_wizard]

The ECMWF has another extreme block by day 8.  Not quite as nicely placed as this one though.

[Phil]

FWIW, I don’t see a prolonged warm-up there with tropical forcing stationed in the EHEM. Short term CCKW passage followed by retrograding anticyclonic surf/more western troughing as the PV falls apart.

 

A flip to warm is possible later on, though. I think?
