PNW April 2023 Weather Discussion

[Phishy Wx]

time to get the summer car out of the garage and get it detailed for cruisin' season

[TT-SEA]

Full 12Z EPS run.    No real cold anomalies in sight... but likely another break in the warmth later next week or next weekend.    A Nino look to the pattern which might be the general rule through the summer per Phil.

EPS maps again after a 3 month break.

Hopefully we can see some thunderstorms. I think the Euro shows some towards the end

No exactly true... I bet I posted EPS maps at least once a week or more through the entire winter and spring so far.   But obviously when your manic cold map posting and euphoria wanes then it usually means there is something I enjoy more coming up.

Definitely potential for convection with a semi-permanent ULL parked over CA or offshore.

[Phishy Wx]

Dang, looks almost like snow in FL

 

 

[Doinko]

Euro shows a huge May snowstorm for the UP of Michigan, I thought that was interesting. Probably less with Kuchera though

The 00Z EPS actually had the same general placement of the major features as the new 12Z ECMWF.     The operational is not too different other than the ridge is stronger but that could just be because the EPS is a smoothed mean.

Death to the Rex Block

Kuchera is impressive too.

Mid 60s on a sheltered deck with no air movement begs for a sun umbrella.  

You might be just ok. Either way, my family and I are praying for your health and safety.

[Omegaraptor]

PDX has hit 70. 
 

HIO and CVO leading the valley at 73. Corvallis RH only 33% as well.

Nope... had to go in before heat exhaustion set in.

Enjoying a break between meetings on the deck and it actually feels hot out here.  Much warmer than it actually is... with full sun and not even a whisper of a breeze.   Not sure I could sit here for a long time.    But that won't be a problem since I have more meetings starting at 1.

I did the same thing. Took the baby and the dog for a walk between meetings. Can't remember the last time 65 felt hot.

[SilverFallsAndrew]

Omg it’s the BEAN! 

[TT-SEA]

There it is...  first 70.

I was there last September and the tourist crowd was pretty big. Overheard someone saying "I hate the bean" there.

[TT-SEA]

For extra measure... up to 72 now in North Bend and 71 at the station near my house.    Likely will reach first 80 on Friday.    You can watch the trees leafing out today.

As @Meatyorologist has said... this is well earned.   After months of colder than normal weather and one of the latest leaf outs possible.     Finally something different.   That being said... I hope summer plays out differently this year.   And that seems more likely at this point since we are now solidly breaking away from the progression of last spring.  

Still note though that immediately after this regime change, we're already threatening to smash Friday's daily record, and we may potenirally flirt with April's monthly record. Lots of 2-10%ile cold this last winter, hardly any records.

[Meatyorologist]

18z looks very, very thundery. Would be a dream setup to camp in the Cascades, or even to just pick a night and find a lookout east.

It's been unusually persistently cold for a long time... except for the first half of January of course. 

[TacomaWx]

67!

Hmm I might have to keep an eye on the forecast and get over there for some chasin!! One of my favorite clips from last September. Not bad for an older iPhone

That's a lot of convection!

You can be on the lake in a $100 kayak or paddle board.  Or on a $5 inflatable raft you got at a garage sale.   Lake Sammamish is a public jewel for everyone to enjoy.  

Or a unicorn Pegasus thing!

77 beautiful degrees in Corvallis today!

[MossMan]

59/39 on the day. Sun never made an appearance. 
Currently 55.

.02” on the day, 5.03” for the month.. 

[Cold Snap]

68/40 for the day today. Currently 60.9.

[MossMan]

Starting to drizzle. 

[Phishy Wx]

 

[Cascadia_Wx]

76/44 day here. Warmest of the year so far by several degrees. Lots of hazy white skies and high clouds.

[Phishy Wx]

made it to 69 today.  it's a sign

[icyasf]

Enjoyed a glorious 81/41F day today at my place.

[Doinko]

GFS looks pretty good for some thunder chances

[Cascadia_Wx]

Yeah the 00z looks really good. Going to be a lot of volatility on the models for next week with that massive ULL just to our south. Wouldn’t take much of a northward bump to give us some pretty interesting weather. Would be nice to see the Euro jump on board.

It could happen. May 10, 1990 was a famous late season snowstorm in the Milwaukee area. That one is especially well known because the forecast was for rain and everyone woke up to an unexpected 4-8” of snow.

Ironically... I was in the Milwaukee area (Waukesha) the day after that storm and saw the tree damage.    

[Meatyorologist]

06z GFS is a dream. Multiple rounds of strong, WHET thunderstorms. Beautiful lightning displays without the fire danger, as well as warm, pleasant afternoons.

Probably my favorite warm season pattern aside from outright troughing and unseasonably cool weather.

[TT-SEA]

No idea what is wrong with the ECMWF... but it only shows 61 at SEA today (yesterday was 67) and Sunday is actually a little warmer after the marine push.     And 68 tomorrow?    All time April record?   

It seems like its cold bias is actually getting worse.
