Wow NWS is actually going for below average temps with above average precip for our region.

October megaridge incoming?

I love seeing Alaska and the Eastern US torch 🔥 in the cold season. 😍

Nice day!

The beauty of October 1st #ArcticBlasts. You get picnic temperatures by afternoon.

I really wasn’t expecting that sort of CAA through the Gorge going into this pattern. Pretty impressive stuff.

Yeah, having the weather so closely resemble late November with lots of green leaves still on the trees was a little disorienting at times.

Looking good for a cool down after the warm up.

Looking pretty wet in the transition too. Probably gonna see a pretty juicy front setup somewhere between Washington state and SW BC.

Don’t forget about Tiger Woods.

Also looks like the 37 at PDX was their earliest since 9/28/1983.

 

The follow December did not suck.

SEA set a low of 40 this morning which is their earliest 40 or below since 2002 which also had a low of 40 on October 1.  I'm guessing it's probably in the top five for earliest 40 or below in the past 50 years.  Thankfully 2002 isn't an analog due to incorrect solar and ENSO.

 

Meanwhile it dropped to 33 here this morning.  Fell one degree short of my goal, but it was still frosty.

Better to focus on what happens after the sun goes down with these pesky early March sun angles.

[TacomaWaWx]

50 and mostly sunny at 11:30am. Should hit the upper 50s and another nice day overall. This morning was definitely the earliest frost I can remember here.

[CulverJosh]

He’s in Culver Oregon now. He was in Clackamas area

Culver is the banana belt of Central OR, but I commute to Bend daily.

I think their reasoning was that it cost them something like 1.3 cents to make and distribute a coin that only has a value of 1 cent.

The U.S. penny now costs more to manufacture than its face value, but our Federal government tends to be a little on the slow side when it comes to realizing the obvious and implementing the obvious solution.

The US also needs to adopt polymer banknotes like they do up there and in other countries. Harder to counterfeit compared to the paper banknotes we have now and also last longer.

[Frontal Snowsquall]

Only one month until cold season!

Looking forward to watching this when it comes out!

29 at Shelton this morning. Earliest 20s on record there, though to be fair it's a different location than most their long term record.

[Jesse]

Euro continues to be WAY slower than the GFS in bringing that front in early next week. Lots of warm SW flow.

Like the pattern though. At least they are originating from the GOA and not Maui.

Back to back 29's in Oly.

This was March 8th at my house...So should I be expecting a repeat any day now?

My sources tell me there was a frost in my little corner of Shawnigan Lake this morning. I doubt there was a freeze though. Probably 35F or so.

Interesting tidbit about the Dec 1983 cold wave - I saw a scientific poster at a conference last year where the researchers came up with an index to quantify N. Hemisphere cold waves. The Dec 1983 cold wave was #1, at least by whatever metric they used in their study.

1 degree this morning in Cut Bank, MT. Coldest so early since Sep. 1934!

 

-4 in Sep 1934

My understanding is the PNW just got clipped by the edge of the airmass and it was incredibly cold. 

 

I used to live in Bartlesville, OK and the #'s it put up there are absolutely insane, especially for highs. 

 

19th: 9/1

Their records go back to 1920 and they have never had another arctic outbreak with highs in the single digits...

 

They ran a -14 departure for the month

EUG apparently even had a White Christmas with snow falling Christmas Eve into Christmas Day. They had another one in 1990 and none since.

Silver Falls had a 22/0 day on 12/23/83.

 

Our last White Christmas was 2015.

[SilverFallsAndrew]

Just looking at Silver Falls #'s for December 2015. Officially 1" of snow on Christmas, a 35/31 day...I got back into town late that night fro Oklahoma. We had about 6" on the ground. Looks like we picked up about 23" of rain that month... Forgot how wet it was.

That is incredible. Yeah, we had -16C overhead and all-time record cold in eastern Oregon despite the backdoor nature of that event. Such a beastly airmass. It's very similar to what late Jan/early Feb 1996 tried to accomplish, but fell a little short in that case. 

[CulverJosh]

Surprising. Figured you wouldve had one 2016/17

Must have been some massive CONUS-wide event.  I think a similar one happened in Dec 2013?

[SilverFallsAndrew]

Surprising. Figured you wouldve had one 2016/17

 

The snow from the 12/14 event mostly melted prior to Christmas, and then it snowed on 12/26 in 2016. 

 

In 2017 we had a dusting of snow on the 24th and then 33 degree rain for Christmas, while PDX had a white Christmas. 

[TigerWoodsLibido]

I don't remember one in 16/17 but the 17/18 one was a Woodburn north event.

Easily the greatest cold wave on record here. Denver was below 0 for five straight days.

[ShawniganLake]

Silver Falls had a 22/0 day on 12/23/83.

Our last White Christmas was 2015.

Shawnigan Lake was 23/6 that day. Which is quite impressive especially given the fact that there was little to no snow on the ground with that cold snap.

[SilverFallsAndrew]

I don't remember one in 16/17 but the 17/18 one was a Woodburn north event.

 

There was a really good snow event in the Central Valley on 12/14. Salem and Silverton both had 5" of snow.

 

We had a white New Year's on 2017. About 8" of snow total. Silverton got slammed that night with 4-5" right in town. Just north Mt. Angel only had a dusting.

Warm nose always hits Mt Angel to Canby to Molalla to OC it seems.

Interestingly I only got about 2.5" with the 12/14 event. There was a warm nose for the first half of the event so it was raining in the foothills while Salem and Silverton were receiving snow. 

[SilverFallsAndrew]

Warm nose always hits Mt Angel to Canby to Molalla to OC it seems.

 

It does. The foothills get hit with the warm nose during a lot of the valley snow events. I recall warm noses on 3/21/12, 1/3/16, 12/14/16, 1/11/17, 12/24/17, February 2014 too. Most if not all of these events I had snow, sometimes a lot (21" on 3/21-22/12), but there were periods of rain when sometimes Salem and Silverton on the valley floor were receiving heavy snow. 

 

Of course there have probably been 40-50 days during the past 8 years I had snow when the valley did not... So it works out. Especially with cold onshore flow. However, typically when there is a widespread valley snow event I end up with about the same if not less snow than the valley. 

[SilverFallsAndrew]

I would also say for the Central Willamette valley, the 2013/14 period-present has been pretty decent for snow and winter time cold. Definitely better than the 20 years prior. 

[TigerWoodsLibido]

Yeah I wanna say the low came inland right over the south valley with that one because I think it was mostly ice here.  I lived in Monmouth at the time and had 3-4" after about a couple hours of sleet.

 

The event on Jan 7, 2017 was the best one here during that cold season, dropping between 5-7" around town.

[Timmy_Supercell]

Snowed half the day at Sunriver yesterday. On September 30th...not psychologically or physically ready yet.

 

Had maybe a couple hours of non-sticking flakes late on the 28th here, at 37 degrees. Yeah many folks who live in an area that gets winter every year are not ready. Kids generally don't really think about trick or treating in the snow here, it might happen this year if it is timed right.

 

Impressive.

But then again, it can freeze any day of the year in Sunriver. I’ve experienced a 30°F low on July 3rd. Once it frosted there on August 1st.

 

That's a cooler place than many, at least in terms of lows. So far upper 30's is about my coolest July low I've seen in all these years.

In some of Dec 2016 I think the Pendleton CWA saw the best out of that month. I had a 5.7" day on the 14th which is not really considered a big storm here, and temperature wise a lot warmer than Jan 2017.

 

Yeah, there were actually a few times I recall getting 40-45 degree rain, actually pouring for hours straight and you would get blasted with several inches of snow in Silver Falls. Sometimes the north vs. south thing really makes a difference.

[Timmy_Supercell]

Prove it.

 

There is someone who used to live in south Salem area, had 12-15" in Feb 2014. I don't think he's a member here but he occasionally posts on one of the FB groups.

Yeah the Corvallis/Albany area got hammered with that one too.

[TigerWoodsLibido]

7" in EUG with the Feb, 2014 action. Pacific City had a foot in some places esp in the nicer houses on the hill.
