June Weather in the Pacific Northwest

[Geos]

Back to toasty Wednesday - Friday on the GFS. Convection flares up on Thursday.

 

 

 

[TigerWoodsLibido]

Inching upwards... lets hope this stops and it hovers around neutral.

 

Buzzkill

[Farmboy]

Clearing up now, warming up nicely. Maybe the ULL is departing the region more quickly?

[Farmboy]

 

Spend a summer here and see if you still like heat afterwards. Everyone I know loves cool, cloudy days during the summer. There is no debate. It’s just a fact that drizzly, cloudy weather is preferable to heat and/or humidity.

 

End of story.

 

 

A very geo-centric, subjective point of view...

 

edit: maybe geocentric isn't the right word, anyway, your opinion is heavily influenced by where you live....   As is mine....

No... just a break between ULLs actually.

 

Its not really moving out until later Saturday morning.

 

Here is 5 a.m. Saturday...

 

[TT-SEA]

Very warm but no extreme heat seems to be the message from the 12Z ECMWF.

 

And it appears to re-building the ridge by day 9.

Everyone here has subjective, biased views.

Oh, that's right....dewey.

I want hot snow and I'll bias my a** off if I think it'll help it come to fruition.

[Frontal Snowsquall]

EPS @ D6.

 

The PNW is (once again) experiencing the most anomalous warmth of anywhere on the planet.

 

Makes me proud! Now just need it to stay here the rest of the summer and then move up into Alaska for the winter.

That reminds me, FrontalSnowsquall should just change his name to NonFrontalHeatLow every April.

Mic drop.

You guys have actually run the highest geopotential height anomaly of anywhere on the planet since May of 2013. And it’s not even close anymore.

 

Statistically speaking, you’ll pay for this at some point.

Mother Nature doesn't deal in stats unfortunately

[Jesse]

Nice to see the Euro back away from extreme heat. EPS also shows some promise toward day 10.

I don't think you'll live that long, Tim.

That's crazy. Got a map? I'm curious about other areas as well...

Tim is actually an android. Getting wet rusts his joints. And not the kind of joints I enjoy numerous times a day.

Sun was out for a bit, but has since clouded over really well this afternoon. Holding in the mid 60s.

Hard to imagine what a 954mb heat low would be like.

[TigerWoodsLibido]

Cloudy in Springfield. Lots of virga.

[Deweydog]

Light rain in Maytown!

Another road trip to OLM?

Tacoma!

Tacoma!

The period of 2006-13 is proving to be an enormous challenge.

Almost all post-Tacoma. Haven't been a Tacoman since August 2006...

 

Of course, I've also been a Fircrester, a Gig Harborite, and a Lakewoodian.

[Phil]

Sure. No doubt the western ridge has been the most prolific anomaly:

Although very sun and heat faded over the past few years, we found literally hundreds of fliers stapled to power poles which promoted the newly-minted -PDO phase.

[Phil]

If you think that’s bad, check out how 2013-17 compares to 2008-12.

 

Yikes!

 

[Phil]

And when comparing the 100yrs from 1851-1950 to the period of 1951-present (NCAR reanalysis V-2c) note the similar type of changes in the circulation.

 

It’s been ongoing for a long time now. More western ridge and stronger Hudson/Baffin Bay vortex as the west-Pacific warm pool and z-cells expanded following the termination of the LIA.

 

[Phil]

Or, put another way, this is how those final years of the LIA looked, when compared to the modern warm period:

 

[Jesse]

18z ensembles hint that the heatwave may end at some point. Step in the right direction.

[Phil]

Isolating the two climate regimes more profusely provides an even more interesting picture.

 

Here’s what 1851-1910 was like, vs 1970-present. The structural similarity still holds!

I approve of these changes.

[Phil]

What this tells me is that, over the last several hundred years, the tropical forcing/z-cell climatology has been taking on an increasingly axisymmetric mode of operation.

 

This modern day circulation is strikingly similar to that of the MWP, and perhaps the majority of the Holocene up until ~ 2500yrs ago. Essentially, we’ve walked back from the LIA regime, which was closer to a full glacial circulation than an interglacial one.
