May Winter Continue 2022 PNW

[Doinko]

Apparently Hillsboro recorded a -14 low in 1930 and a -10 in 1950!

[SilverFallsAndrew]

Silver Falls average low was 14.4F in January 1949. The only month on record where they averaged a sub-20 low. However, they are missing January 1950, and January 1930 and 37 were likely very very cold, but their POR didn't start until 1938.

Starting to look pretty dry in NW Oregon. Drought concerns may start creeping back in.

PDX hasn't recorded a sub-20 low since 2016-2017. Obviously some of that has to do with UHI, but Hillsboro hasn't recorded a sub-19 low either (19 in Nov 2019 and Feb 2022). I hope we can somehow get a sub-20 low next winter. Maybe we're paying back for the 11 degree low at PDX in 2017 and the 3 degree low at HIO in 2017.

Kind of fluky thanks to either seasonal timing of air masses or timing of shortwaves during cold episodes. But it’s also a pretty good illustrator of the fact we’ve been on the periphery of most cold patterns since 2017. Tough in those instances to eliminate mixing and/or cloud cover.

Haven’t heard from Joshua in awhile!

Just hit 2.50” of rain for the month. Looks like the bulk of the precip is closing in.

[Cascadia_Wx]

Radar is filling in nicely to the west of the metro area. Mostly cloudy and up to 63 here.

The coldest PDX temp each winter:

2017-2018: Dec and Feb

2018-2019: Feb

2019-2020: Nov 

2020-2021: Feb 

2021-2022: Feb 

I see what you mean about seasonal timing, most of our coldest temps in the past few winters were in February. Maybe if some of these patterns happened in January we'd have had colder temps.

Raining here in Bethany.

[Skagit Weather]

First actually wet day since May 5th up here. Up to 0.24" on the day.

[Doinko]

The GFS is still insistent on a random hurricane later this month

[Chewbacca Defense]

Spectacular day in Bozeman, came out to the Bozemann Pass rock climbing area so my son could get one last climb in

[Doinko]

Raining heavily now

Didn't the winter of 1948-1949 set a record in Portland for days with at least an inch of snow cover? Until the next winter broke that record.

Way more than Portland. Classic icebox winter across the whole western half of the continent all the way down to Mexico.

I can picture Alpharaptor writing all sorts of letters to the opinion page of the Oregonian complaining about the constant, inane cold that year.

Definitely some heavy rain moving in, kind of surprisingly so.

HIO picked up 0.35" in the last hour.

Yep. Wouldn't want such a devastating flood but certainly wouldn't mind following that analog otherwise.

You wouldn’t get one. There are a lot more dams on the Columbia now than there were then. The Fraser, on the other hand, is still free-flowing, so a 1948 replay is still very possible here.

At my house it was raining very heavily for a small bit of time, now it's moderately raining.

[FroYoBro]

Heavy rain here on the backside of Bull Mountain. Beaverton/Tigard area. 
 

 

 

AHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!

We could absolutely still see significant flooding even with the dams, it just would take a higher volume of runoff to produce similar results to what we saw back then.

I recall the Columbia River getting pretty high in late May 2011. Cottonwood beach out in Washougal was completely underwater, including some of the riverside forests.

Yeah, it stayed at flood stage for awhile in both 2011 and 1997 from the spring snowmelt.

Bull Mountain??? OK Jacuzzi Casanova

[MR.SNOWMIZER]

4.5 inches of rain on the month.

[LowerGarfield]

The three of us did some storm prep this morning. Certainly a balmy day here with a breeze from the SE before we get a shift to the SW later with the convective cells

 

[snow_wizard]

Looking like next weekend is going to find a way to be ugly now.

[Omegaraptor]

Corvallis at 66 dew 59. Feels like a convective kind of day. Beautiful outside though.

[snow_wizard]

BTW April ranked 14th coldest for the Puget Sound Lowlands since 1895, East Slopes of Cascades 3rd coldest, and West Slopes of the Cascades 7th.

Bet it would have been even colder if it hadn’t clouded or rained all month

Really heavy band of rain just moved through. Picked up about .20” in ten minutes. 

Looks and feels great out there right now with dark clouds, green vegetation and slightly humid air.

[TigerWoodsLibido]

69F and mostly cloudy. Pleasant day.

[TacomaWaWx]

0.40” so far…back edge of the front is closing in but it was a decent soaker.

Looks and feels tropical almost here. Even got the window open now.

That flood was followed by probably the best 18 to 20 month run of weather in the 20th century

I like where it ends.  We need that GOA ridge to stay to shut off this damn gloom.

55 is tropical?  Going to be way below normal for max today.
