April Weather in the Pacific Northwest

[SilverFallsAndrew]

Looks like a typical April day on tap

[TT-SEA]

Incredibly nasty out there... roaring wind and sideways rain and 38.    This would be a terrible January day.

 

The nice weather cannot come soon enough.   This April has been a complete mess and I hope we are rewarded nicely now.

Pretty typical for April. I remember many years driving up into the foothills to see April snow. A very late 90s feel to this month so far. Good weather is on the way.

A drought emergency has been declared in a 2nd Oregon county. Very unfortunate situation...

Summer 1999 repeat?

[stuffradio]

Today is the snowiest day on record for the Okanagan on April 16.

 

I didn't create this graphic.

 

[stuffradio]

Here's a graphic from basically the senior local meteorologist

 

 

 

I've received .8" of rain so far today. I'm 0.6 inches away from reaching average preicp for the month.

Summer 1999 repeat?

 

This is nothing like 1999.   April of 1999 was actually quite pleasant.   There was 21 dry days here that month.    We have had 1 so far this year.

 

There was 2.06 inches of rain total at Snoqulamie Falls in April 1999... they are almost to 10 inches so far this month and its only the 16th.   

 

April 1999 looks like a dream compared to April 2018.     

[SilverFallsAndrew]

8" even on the month as of 7am. We had 8.80" last April, so still not as wet as last year.

We desperately need this rain. At least in Oregon.

Yeah... we need more rain like another hole in the head up here.  

 

Its ridiculous now.

9.83 inches in Snoqualmie so far this month... 6.39 inches last April.

 

Over 13 inches so far up here this month and dumping rain now.

Today is much drier than I expected. More showery instead of steady rain.

[SilverFallsAndrew]

Weekend looks nice.

[TT-SEA]

Tim’s crap weather has reached DC..3-4” of rain in 2hrs last night, several tornado reports, now 40mph winds with a rain/sleet mix.

 

Glad to share the wealth!

[TT-SEA]

Weekend looks nice.

 

Saturday is sort of iffy here but Sunday looks awesome.  

 

Wednesday - Friday also look nice.

 

Very pleasant April weather ahead starting Wednesday.

Whatever the case I am sure we are in for another record hot summer with multiple runs at 100 and a hellish wildfire season. So fear not!

All joking aside. I would set the over under for temp departure in the Willamette Valley this summer at +2.5. I would also put the over under for 100+ days at SLE at 3.

Science!

FYP.

[MossMan]

In Bellevue currently...nasty nasty weather.

Might see some cooling of the off-equator Pacific over the next few weeks. Stronger easterlies developing with a more favorable meridional pressure gradient too.

 

[Phil]

Why does it always have to be an extreme, either/or scenario when it comes to summer/winter? Ever think it might just wind up being an average, transitional, back/forth type of year?

 

That’s how it looks to me so far..there’s been a long period cycle in the subtropics this year that’s structurally emulated the Branstrator wave to some degree.

Average is boring and everyone complains.

[Jesse]

Science!

 

I am predicting a nice summer. Perfection. Everyone should be backing me on this!

An average summer would feel unbelievably cold.

Nice try, I see through your jokes!

[weather girl]

To be fair... PDX is at 3.10 inches for April which is about 200% of normal.   Its not like its been dry down there this month.

 

PDX is also just about normal for the rainy season and for 2018... within a inch of both.

 

And Salem is at 4.68 inches for April... which is exactly the same as SEA.     Salem is also above normal now for the rainy season and for 2018.   This is also the 7th wettest April ever at Salem... with a period of record going way back to 1893.

 

I would say there has been no north-south gradient at all this month.   PDX has just been a little drier than Seattle, Olympia, and Salem.

 

*****

Over the weekend, Mark Nelson mentioned how wet Salem has been this month, also comparing to Portland.  It's 40 degrees right now.  There are some nice days coming, though. 

 

Unless we're going into a Nino, I don't see a super hot summer this year. For reasons, not science.        

[Timmy Supercell]

Light snow and 35.

 

Just ended up with a trace on roads/sidewalks. Maybe a bit more on grass.

[Jesse]

Nice try, I see through your jokes!

 

Hopefully they are more transparent than the beautiful ash-choked skies we will all be enjoying on our decks in just a few months!

It depends on the day and time of the year, really.

[wx_statman]

What about the high at 28 at MSP yesterday?   Is that a record?

 

Look at the lovely April they are enjoying... 26 inches of snow so far and ridiculously cold.   And they have had snow on the ground almost all month.   They briefly cleared the deck late last week just in time to get buried again. 

 

 

Crazy month. Yeah, the 28 at MSP yesterday was the latest max in the 20's on record. Minneapolis has an older maximum of 20 on April 16, 1875 but that was obviously pre-airport.

I'm thinking either at or marginally above averages. My main concern though is that we at least get a decent convective season with many wet storms on the east sides.

Sweaters will be flying.

[Geos]

Been pouring here in Bothell. 

 

Saturday was sure a nasty day, but yesterday wasn't too bad just not much sun. Managed to get a few things done outside. 

 

Edit: Just heard a clap of thunder!

[Geos]

Intense returns in Snohomish County right now.

 

 

Yet another snow system for the Midwest!

 

[wx_statman]

Spent a couple hours installing a weather station on the roof of Cramer Hall at PSU this morning. Showers, low 40's, and gusty south winds. Nasty! I don't envy those construction guys who do this 8 hours a day. 

[stuffradio]

We'll see how much rain is left in this system. I'm at 1" of rain now since last night, 0.2" since my last post about the rain a couple hours ago. Maybe we'll reach average today since I need less than .5 inches now.

[Phil]

Interesting paper on the QBO’s modulation of the relationship between the MJO, the Pacific Jet, and the regional wavenumner.
