May 2020 Weather discussion for the PNW

[MossMan]

Up to .14”

[Deweydog]

[MossMan]

.16”! One minute to go! It’s dumping buckets! Will I make it to .17”???

[MossMan]

No.

Up to .01” on the day however!

[Timmy Supercell]

Nice amount of rain here! It looks like the thunderstorms want to begin real soon, just not sure when. lol

[TacomaWaWx]

Picked up 0.38” yesterday and another 0.12” so far this morning to hit 0.50” in the last 24 hours...1.57” for the month. Currently 53 and raining.

[TacomaWaWx]

Rain pounding down on the roof now again...looking forward to what should be a showery day here and maybe we get lucky and get a couple rumbles of thunder.

[TacomaWaWx]

The 00z EURO shows a nice Memorial Day weekend with hot anomalies by Memorial Day. Governors of Washington and Oregon, time to open up the beaches!

Euro run wants to bring in some hot weather in the 7-10 day range...gfs wants to keep the cooler unsettled pattern going in the 7-10 day range. Kind of get the feeling we will end up on the dry and warm side but we will see. Either way the next week looks unsettled still with rain at times.

[MossMan]

.29” so far on the day, 2.57” for the month, and 30.09” for the year.

52 degrees.

Warm and wet month....getting some sunbreaks here now! Hopeful that it gets unstable enough for some boomers.

Wow temps in the 90s? 

[TacomaWaWx]

Wow temps in the 90s?

 

Last nights euro run showed low to mid 70s one day and mid to upper 70s the next around western WA....much warmer in OR.

[SilverFallsAndrew]

0.26" overnight. Kinda lame. 

[TigerWoodsLibido]

57F and mostly cloudy. Rain on the way. Probly won't be much but we need every bit right now.

[Blizzard777]

Now officially our wettest day so far this month at 0.35”. Sounds great listening to the rain with the windows open.

Lol, I did that as well last night !

 

.58 storm total so far

1:10 am nest cams showed a really nice heavy shower going through

[seattleweatherguy]

UPDATE...A few areas of showers already are continuing to

develop around the area, with a broken to overcast cloud layer

over Western Washington. Expect continued breaks in the cloud

deck, along with cooling temperatures aloft, to increase

instability into the afternoon and evening. Stronger showers may

contain brief downpours, small hail, and gusty winds, with a

dominant motion from south to north as they develop. Isolated

lightning is also possible, mostly south of a La Push to Tacoma

line, as well near the Cascades. Updated aviation and marine

sections follow below, along with the previous short/long term

discussions. Cullen

Sounds like the winner is the south part of the puget sound again. Hope to hear some thunder today!

Here's some blog post Mark and Cliff has written about the "Brookings Effect". One of the most extreme "Brookings Effect" heat waves of all time was back in early July 2008. July 8 and 9 was incredible, got to 108 on the 8th, then only down to 85 the next morning, then back up to 102 during the day. HOT!

Good luck sleeping that night. I would of needed an ice baths.

Portland had 0.21 yesterday so now 0.12 above normal for May.

Memorial day weekend is the unofficial start of summer.

And the GFS totally disagrees... its way more zonal. And its been right in the long range more than the ECMWF lately.

[TacomaWaWx]

I watched the video...pretty clear rotation wonder what caused that to happen...maybe air rising over the sound or something?

[TacomaWaWx]

Radar is starting to show lots of small “popcorn” looking cells forming...getting some light rain again under partly sunny skies.

[Jesse]

12z GFS looked really good for Memorial Day to the end of the month. But the ensembles trended much warmer.

 

Last night’s 00z EPS trended way warmer in the 7-10 range as well. So at this point I think it’s safe to expect a very hot end to the month, unfortunately.

[TacomaWaWx]

Better picture of it...wish I had actually gotten to see it.

[Jesse]

Huge jump on the GFS ensembles compared to the last few runs.

 

 

I think the question now isn’t whether we hit 90 the last week of May, but how far into the 90s we get.

[Jesse]

Better picture of it...wish I had actually gotten to see it.

That’s awesome looking. Definitely looking forward to some potential action later today!

[TacomaWaWx]

I was kind of surprised to see a picture of a funnel cloud this morning just a couple miles away when it didn’t seem like there was too much action going on radar. Hopefully it’s a sign of a fun afternoon coming.

Yeah the GFS is on the cool side for Memorial Day while the GEM is on the warm side but not as warm/hot as the EURO. Right now I'd go with some type of blend with something like the GEM solution verifying.

Wow temps in the 90s?

Possible down here but likely just 80s at best for you guys up there depending on how close to the Sound you are at.

[Frontal Snowsquall]

Memorial day weekend is the unofficial start of summer.

I'm going camping Memorial Day weekend so I'm hoping for dry weather.

[seattleweatherguy]

Any site i can look at in terms of cloud cover for today?

Not quite PNW but there is a Winter Storm Warning for the northern and central Sierra Nevada.

[Frontal Snowsquall]

The 12z EURO not backing down with the warmth for Memorial Day. Continues to be the warmest model for the beginning of next week.

 

[Jesse]

Euro is a lot cooler than last nights run, but I’m sure some nice red maps could still be produced from it.

[Jesse]

Looks like I was too slow...

[TT-SEA]

Its inevitable that the ECMWF will slowly cave to the GFS.

We are planning to visit Yosemite in a month (assuming it’s open) so good news for the waterfalls!
