April Weather in the Pacific Northwest

[TT-SEA]

2010 had a record warm January/ February combo. A lot of March was also pretty warm.

 

Ahhhh... maybe I am thinking of 2008.

[Jesse]

Ahhhh... maybe I am thinking of 2008.

 

2008 had significant warm spells in mid-April and mid-May. You brought up the mid-May one just last night.

[TT-SEA]

Go take a walk or something. I just don't get how the weather here can stress you out so bad when you are gone. It was the same deal in Hawaii.

 

I am not stressed at all.

 

Sounds like it high stress there though trying to get through this heat.

We are just trolling. Although this isn't my favorite weather, it isn't that bad.

 

If people actually complained about this stuff the way you and MossMan do about the rain there would be another five pages added to the forum today.

But this year had some impressive warmth in January and March as well.   

 

It has been coming back with some regularity.    I feel pretty good about summer.   And that does NOT mean I think a hot summer is in the cards.   I don't think that at all.

True.

Probably a variable one. 2008 certainly wasn't terrible.

[Phil]

Side note... the recurrence of warm weather since January has me encouraged for the summer.

 

Years like 2010 and 2011 did not have that at all.

Tell that to January 2017. Also, a good portion of January 2011 was ridgy out there, IIRC.

PDX set their January record warm MIN of 55 in 2011. Little known fact.

Really looking forward to the Friday-Monday period.

I would just like a wet, convective May. A 1993 repeat would be perfect.

Yeah. Doesn’t look to be in the cards now. Hopefully things will change.

[BLI snowman]

I suspect we'll continue to see little fluctuations for awhile, but lean towards drier and warmer.

[SilverFallsAndrew]

Tim is high on southern sunshine and in full troll mode!

Climo and the models would dictate as such.

 

Maybe we can get a turn around by late next month just in time for Rose Festival Low season!

I am high on PNW sunshine over the last 3 days.    

[Frontal Snowsquall]

Portland, Troutdale, Vancouver, Hillsboro and McMinnville all set record highs today. We have to go back almost 100 years when MMV hit 83 in 1923 for the previous record. Pretty impressive it took this long to break it.

[Deweydog]

This has been a 100 year heatwave.

[ShawniganLake]

Much warmer than yesterday here. Still 72F this evening. Heading to the local cooling shelter.

Stay safe, the asphalt could melt your tires or soles of your shoes....

[Deweydog]

Yeah, I thought about doing some research earlier to see how often it had happened.

 

Then I realized you only had to go back to 2016 for four straight 80s in April. That might have been the most impressive April heatwave on record for PDX, though.

Looks like 1998 was the only other candidate until 2016.

Meanie.

[Deweydog]

Meanie.

95 year, I guess...

Not quite but close!

[TigerWoodsLibido]

And to think you were worried it wasn't going to reach 84! Is 86 a record for your location?

As far as I know yes, first temp record we have broken in a while I think.

[Frontal Snowsquall]

It's already too hot. Got this new costco cooling shirt. It works ok, Def not cooling enough

That's a pretty interesting concept, I never heard of it before. Is this what you have? I might go buy one now.

1926 had this stretch downtown:

 

4/24: 81

4/25: 83

4/26: 84

4/27: 93

4/28: 91

4/29: Deadly marine push

Nice! SLE only hit 82 from the looks of it. I'm not doubting the 86 reading though, it's legit to me.

Does Monmouth keep official records?

That was also the warmest April in Portland history (looking at both the airport and downtown) with an average temp of 60.2, which is 8 degrees above the modern average and was probably even more of an anomaly back then.

 

Made 2016’s 56.9 downtown / 57.8 at PDX look a little pedestrian.

[MossMan]

Wonderful evening!!!!!!!!!!!! !!!!!!!!

[wx_statman]

If it wasn't for 2016, today's 84 at PDX would have tied the warmest pre-4/26 max on record. 

 

84 on 4/14/1947

84 on 4/20/1956

84 on 4/25/2018

 

Of course April 2016 blew away our PDX-era climatology by hitting 85 on the 7th, 87 on the 18th, and 89 on the 19th. 

[seattleweatherguy]

I want to know more.

It's called 32 degree cool t shirt. It supposedly keeps you cool.You get 2 for 7

[TigerWoodsLibido]

Does Monmouth keep official records?

I don't think so. There are 3 good stations in town that I use for current conditions but I just use Salem for history as it's usually pretty similar to us.

New blog post from Mark regarding the final day of our record breaking heat wave.

 

"It sure felt like July today! Here in Portland we started in the 50s and ended well into the 80s; a typical mid-summer day. Except that it’s the 25th of April. The result was several more record high temperatures, mainly in the metro area:

 

 

And we did that with extremely weak offshore flow. Even in the Gorge the wind died down to a slight breeze plus downslope wind off the Cascades disappeared. So it’s quite impressive from a meteorological standpoint we were able to make it into the mid 80s. Models absolutely nailed the atmosphere overhead. 850mb temps at Salem were 16.6 degrees on this afternoon’s balloon sounding.

 

WHAT HAPPENS THURSDAY?

 

A very interesting setup with the thermal trough (warmest air) sitting from about Kelso to just east of Salem and Eugene. That means west of that line onshore flow kicks in during the afternoon = cooler. But from Kelso/Longview to the Portland metro area we get a light easterly flow once again as high pressure briefly strengthens east of the Cascades. Result? All models are adding 2-4 degrees to our highs tomorrow. 85-86 is likely throughout the Portland metro area. You can see the bubble of warmer temperatures from Portland north on the GFS and the cooler temps to our south. This is the 5pm Thursday forecast:"

IMO it's all going to depend on if clouds arrive before peak heating tomorrow afternoon. Tomorrow the hottest 850mb temperatures yet of this heat wave is suppose to arrive tomorrow afternoon. If clouds can hold off until after 5pm then I think PDX has a chance of tying the all time record high of April which is 90. Everything has to go right but it's possible with the 850mb temps we will be getting.

[Jesse]

Hopefully that marine push moves in earlier than forecast tomorrow.

 

MOS has PDX only hitting 81. Maybe it will be right for once.

That is where we differ...I’m hoping it gets delayed... until October!

If you want 80s every day between now and October you are living in the wrong climate.

[ShawniganLake]

Saturday thru Tuesday look pretty showery

 

[TT-SEA]

00Z ECMWF was nice... scaled back precip somewhat for the weekend and the ridge looks more stable and broad later next week.

 

I find it encouraging that ridging pops back up already next week given the significance of this current warm spell.

Hopefully this will be the general theme throughout May...
