May Weather in the Pacific Northwest

[Deweydog]

Unconfirmed reports of 81 in front of the Dress Barn at Cascade Station.

[El Nina]

Just 77 three miles away at KVUO.

 

TTD hit 79 though. There might have been a little bit of offshore flow ahead of the marine push that legitimately bumped them there. Still, warmest official temp in western Oregon/Washington aside from Medford.

Their lows are ridiculously high, too.

[Jesse]

The lows are a joke, moreso than the highs.

It was 37 here a couple mornings ago. I didn't check what PDX was at the time but I'd guess like 45

[TT-SEA]

This moisture plume at the latitude of Hawaii has been there for most of the last 3 months.   At least since I started tracking it in early February before our trip to Hawaii.   Its been really unusual.    It appears to be equatorial tropical moisture displaced far to the north of its normal location.    Hawaii is normally sunny except for windward clouds.   But its been much cloudier and wetter than usual across all of the islands.    Just wondering if Phil can offer some insight.    

 

I am really surprised to see it still going in May.   

 

[Frontal Snowsquall]

Wow looks like PDX hit 80 today. I wasn't expecting that especially with all the clouds. The highs were only suppose to be around 74-76. We definitely over achieved today.

[TT-SEA]

You could theoretically go park your car as close to the runway as you can get at around 5 a.m. and take the temperature with an accurate thermometer to see how close it is to the PDX reading.

 

Like right here... off Marine Drive.   Just to the north of the runway.

I don't think the sensor itself is bad or inaccurate. Land use changes have made this spot much worse at radiational cooling than it was historically, though. And not very representative of the area unless you live in the middle of a very large parking lot.

Interestingly... there are golf courses to the west and southwest of PDX which probably keeps it greener at least on that side in the summer than other areas.    Better than massive parking lots.

There is a lot more pavement around the area than there was even 10-15 years ago. 

[TT-SEA]

GEM continues to be way more ridgy than the GFS later next week and weekend.

Look at Oregon hogging most the Columbia.

When you zoom out... the area around PDX is a lot less built up than much of the rest of Portland.

 

[MossMan]

[TT-SEA]

Go Canada!

 

No doubt!     

[Jesse]

Most of the rest of Portland has more trees.

 

Also, if you look at past maps, you can see the dramatic land use changes at PDX in recent decades.

[SilverFallsAndrew]

But Jesse is right. Lots of development along airport way over the past 10-15 years. IKEA, multiple hotels, and other big box stores.

 

Much more development than what I always talk about around the Salem airport, and that has caused a obvious UHI.

 

Just not quite as significant at pdx because it was always part of the UHI, it’s just gotten more pronounced.

[TT-SEA]

Hey Phil... you don't need A/C that much compared to other areas of the country.

Hmm...my box contains three different climate zones, with a temperature range of at least 10*F. Will require mental gymnastics to figure this one out.

[Phil]

It was 94.6*F today. How the hell can you possibly enjoy this s**t, Tim? HOW?

 

Opioids? Booze? Both? I demand to know.

Not bad once and awhile... great day to be the water with a cold drink!

 

I prefer 80s... but we enjoy the hot days too.

 

Way more fun that 52 and drizzle. Waaaaaaaaaaay more fun.

I love 90’s especially with the typical lower DP’s in Eastern Wa...out on a lake or the Columbia on the boat or jetski...doesn’t get much better! But I also never complain when the 90’s come to visit on the west side either!

That’s a good thing since you complain about basically everything else.

Yeah... it's a big party on the water when it's in the 90s. Everyone is out. Our reward for dealing with months of gloom and drizzle.

[TT-SEA]

Going to be another big crash from Tuesday to Wednesday. Around 80 to 50s with rain per the 00Z ECMWF.

[MossMan]

That’s a good thing since you complain about basically everything else.

I don’t complain about snowy cold, Arctic cold, windstorms, pre warm frontal partly cloudy/breezy days, thunderstorms...really I don’t complain about anything except 49 degree heavy drizzle day after day after day after day.

[TT-SEA]

Some nice improvements on the 00Z ECMWF later next week. Appears to be more in line with the GEM by day 8.

[Jesse]

So climo here for half the year.

[Timmy Supercell]

So will this be another above average May? We'll find out! 

 

And I'm curious about the start of my next round of convection beginning soon.. If it's tomorrow May 4th.. History would have an interesting way of repeating itself. But chances are Saturday will start it off, most likely.

 

05/04/2016 - heavy hailstorm and one of my most memorable lightning events in K-Falls

05/04/2017 - First Tornado Warning since August 2005 in southern Oregon (Crater Lake supercell)

05/04/2018 - (to be seen..)

 

Reminds me of another date that likes to repeat here

 

08/05/2012 - Downtown K-Falls - 60-70+ mph winds, flooding rains, power out until next morning.

08/05/2014 - Keno (neighboring town to SW) - 1" hail accumulating 3-5" deep on roads. Shelf cloud seen from here.

08/05/2015 - Downtown - T'storm at 2am shaking the house. Obviously I didn't start sleeping until after that.

08/05/2016 - lost of nearby lightning in vicinity, constant rumbling to my north. Mammatus/rainbow display that lasted 2 hours.

I will look forward to 08/05/2018 and hopefully tomorrow evening!

This next winter is also an 8 winter so it will surely deliver

You hate 50s and love 80s? In that case, we should just switch houses.

 

[Phil]

Greenland-Baffin Island perma-vortex stays put on the 00z EPS. The first Eurasian wavebreak is also showing up during the week 2 timeframe.

 

 

 

 

 

 

[MossMan]

49 degree heavy drizzle for 6 months is not climo.

I have a good feeling about this winter!

[El Nina]

Misty morning! Feels refreshed outside.

[Jbolin]

Opioids? Booze? Both? I demand to know.

Isn't everyone high, drunk, both or a variant of the two at some point during the day? 

[TT-SEA]

Big improvements on the 12Z GFS for later next week and next weekend.     Now looking much more like the GEM and ECMWF.

EPS came in much troughier for the 7-10 day period, fortunately.

Interesting that all 3 models are going with ridging now. Maybe the EPS will cave today?

[TT-SEA]

No drizzle here this morning. Sun is peaking out as well.
