Pacific Northwest Weather - May 2023

Let’s get this started. Could you tag this, @iFred?

Thank you @Phil

Jesse always has to make sure I don't make the monthly PNW thread because he's anti Anti Marine Layer, which is pro Marine Layer.

Mostly cloudy with some spotty light rain showers around and a low of 51. Some nice variable late spring weather showing up the next week or so.

[Cascadia_Wx]

Looks like PDX ended up with a -1.1 departure for April. Average high even stayed below 60. Pretty impressive considering the late month torch.

Over 5” of rain on the month for them as well.

Cherry trees were in full bloom at the in-laws in Tigard last night. One of the latest blooms I’ve seen of those trees in the last decade but very pretty nonetheless.

Looks like an ornamental pear (white) and crab apple (pink) to me.

Today is revitalizing after the last day or two of warmth...will be short lived sadly then Texas where it will be hot and humid. Gotta enjoy this weather today while I can.

[SilverFallsAndrew]

EUG actually ended April exactly average. SLE had a spankin' -1.4 departure and came in with a mean of 49.9.

Must be cool and wet then. That is less than stellar for most.

Coastal SoCal forecast colder than it usually is in winter!

Probably worth noting that if you want distinct seasons, coastal SoCal kind of isn't really known for having them.

Variable pattern with an active and fast-progressing MJO.   I believe the tables will turn again next week as the next warm spell comes into view.     This will be downvoted by the usual folks of course, but doesn't change what nature is doing or what will happen.

Bring on the variable pattern!!  Give me an occasional sunny day or two to enjoy all the green goodness that the clouds and rain bring us.

Thu/Fri might be fun for folks on both sides of the mountains

Going to keep seeing cooler than normal conditions. A blessing indeed.

As long as they stay in PNW to satisfy the thirst of our rain lovers who don't need vitamin D to thrive and like to have pale skin all the time, I am happy.

Where is the big California cutoff low?

Next 6 weeks will be the epitome of pattern variability under changing background tropical forcing(s), seasonal forcing(s), and an active MJO/CCKW component (often associated with the former & descending easterly shear/-QBO, which we now have).

Doubt any pattern will hold for more than a week from now until the summer solstice at least. However averaging it out CA/SW US will probably end up cooler and WA/BC/Northern Plains probably come out warmer.

Then (probably?) a relatively uneventful pattern for July/August. Relatively weak 4CH, saggy troughing/lowish heights in West/SW, and/or southern US. Meanwhile West/Central Canada & Northern Plains probably running a bit on the warm side, but anomalies running cooler in Northern Intermountain West and PNW (compared to May) but probably still on positive side.

In essence, nothing to write home about.

Nothing like 93 in January and 61 in June.

I liked ML Loather. Fear and Loathing in the Marine Layer.

Sigh it wouldn't be may without concern for hail (though I also find it fascinating too). Have a probability of damaging hail/t-storms tomorrow in SE WA/ID Panhandle. debating if I want to deal with the trouble of protecting our cars again if we don't get anything...but couldn't afford to fix it if it caused any damage.

[TT-SEA]

Next warm spell showing up on 12Z EPS.

We had relatives come out to visit from Minnesota a few years ago, their 1yr old Suburban was full of golf ball size dents on their roof and hood! Between the salt rust and the hail damage those Midwest vehicles do not stand a chance lol.

My brother-in-law in Minnesota has a side business buying and selling vehicles and he always flies to the west coast to get specialty cars and then drives them back to MN since he can get a premium for them there.

A little bit of warm weather can do the trick

12z EPS looks pretty good for the next couple weeks. Liking where the control run goes in the long range.

[KeyPeninsula_Wx]

56/49 today…getting some light rain now. Have had some sprinkles at times today but never enough to wet the ground. 

[KeyPeninsula_Wx]

Starting to look like there’s a good chance of some snow at some points this weekend and into next week in Yellowstone…some snow in the higher terrain in WA/OR as well. 

[Omegaraptor]

 

11 days of progress. Wow.

[Ken in Wood Village]

Severe Thunderstorm Warning on the East Side of Oregon. It looks like it has been going on for awhile. I just woke up from a nap. It was a long day at work

Back to April we go............

[Ken in Wood Village]

That severe thunderstorm is still rocking

[Port Angeles Foothiller]

Cool clouds tonight
