August 2019 Weather Discussion for the PNW

[Frontal Snowsquall]

Hillsboro got down to 3°F in January 2017 (thank snow cover). PDX only got to 11. Not sure if this was pure UHI or if something else was at work (ie east winds), can someone confirm? I don’t think UHI alone can produce an 8°F difference unless we’re talking about a megacity here, which Portland is not.

That was the coldest day I ever experienced in my life. Hillsboro only made it up to 25 that day for an insane -26 departure. HIO finished -6.9 for the month but it was still a full degree warmer than PDX which finished at -7.9.

Smokg.

A little smog and moisture and probably many other sources. And even so... it looks like a perfectly normal summer evening in Seattle. We have genuinely thick brown haze and bad air quality during winter inversions with no wildfires within thousands of miles and everyone on here seems to love those.

 

And the last rain event actually ushered in the worst of the haze which has slowly faded since Saturday morning.

Thick skin McGee they call him.

Post count matters...

[Jesse]

Quite a cell up around Mt. Adams.

We’ll be up there for three days of field work starting tomorrow. Accepting thoughts and prayers!

I never even notice post count... only when you mention it.  

 

Not sure how you think it matters... but a high post count is not something to be proud of.    <_>

Wow that cell southeast of Rainier is still going. There has to be some heavy local flooding in that area from that. Not sure how to pull up a report from over there. That was like an extreme convergence set up.

[El_Nina]

With the daylight hours waning so fast now, it's time to improvise.

Why are they so small? Late start? I see lots in people’s back yards this time of year and they are usually 2-3’ tall now.

[TacomaWaWx]

High temp hit 80 here today was very pleasant perfect summer day. Could see that thunderstorm near mt.rainier from here was pretty cool made some pink anvil clouds around sunset.

Your gonna dye.

[MossMan]

Already down to 56 chilly degrees.

Still in the 70s here.

I just found random seeds in some flower I bought a few weeks ago. Thought I'd give it a shot.

I don't have a setup or anything and don't really know where I'm gonna go from here. Stay tuned.

I'm just using some random lamps from throughout the house to aid them with some light.

You really want a full spectrum light bulb.

You really want a full spectrum light bulb.

I'm probably gonna upgrade once they get big enough to where this wont work anymore.

06z ensembles really backed off on troughing in the LR.

 

Cloudy and 59 this morning.

Dont know what he is basing this on, but . .

August into Sept going to be ugly cold for western and Central canada summer was short, Conversely the northeast once past the cool 10 days should be quite warm into September.. stretching back SW to Texas Central US, as usual may be where the cold holds in the means

[TacomaWaWx]

06z was a bit wetter for western WA overall on this weekend but the next week no rain essentially which was a big change from the previous 2 runs.

[TacomaWaWx]

Marine layer back today. Took until about 11:30-12:00 yesterday to burn off. Currently 57. The last 3 days were the first time this summer we actually got 3 days of 80+ weather in a row. Hasn’t happened this year until now.

[TigerWoodsLibido]

Cloudy and drizzly this morning.

No sign of a marine layer here, currently 65F and sunny.

[Front Ranger]

Marine layer deeply entrenched here at the coast. Only saw sunshine for about 30 minutes yesterday.

So summer is over according to Him

For western and central Canada... at least according to him.

 

The latest ECMWF weeklies through the middle of September show plenty of summer left for us... its quite warm through that period overall.  

[SilverFallsAndrew]

Nice morning fellaz.

To see the ecmwf weekelies do you need to pay a subscription? 80s and or 90s? warm?

Isnt Bastardi east coast bias though

There is no specific temperature output... it just shows warm surface temp anomalies for us for the most part through the middle of September.    

 

Phil said the ECMWF weeklies have a warm bias with surface temps though.   Still... there is no real cold air anywhere near us on the latest run for the second half of August into September. 

[TT-SEA]

Isnt Bastardi east coast bias though

 

Yes... but the pattern upstream (i.e. in the west) has a direct impact there.

[MossMan]

Chilly marine layer this morning. Seems deeper than yesterday’s.

It is a little deeper... it made it out here but we are right on the edge and the sun appears to coming out again.    It was sunny until about 8:30 a.m. and then the marine layer squeezed in here around the hills.  

[Omegaraptor]

 

Saturday afternoon 2m temp anomalies on the GFS. Imagine if this happened in December.

[ShawniganLake]

The 12z ensemble is more to your liking

It would be neat. But the upper level pattern on Saturday would not produce notable cold in the winter.

Ah, that makes sense. You need arctic air.

[Omegaraptor]

Cliff Mass up to seven total rain posts since July 1.

[TacomaWaWx]

The 12z ensemble is more to your liking

definitely looks closer to the 0z and 18z runs yesterday than the 06z this morning. looks wet this weekend over the whole PNW. We will see how that actually verifies it’s stilk 5 days away. Looks wet after day 10 on the 12z as well.

[TacomaWaWx]

Been a little drizzle at times this morning. 59 and still socked in by clouds.
