snow_wizard Posted January 27, 2016 Report Share Posted January 27, 2016 There are so many excellent months in the 1880s that get talked about, but January 1886 is largely overlooked in spite of featuring a fantastic run of cold and snowy weather. Amazingly this was a weaker than average winter for that decade, but it sure looks fun! These records are from Tacoma WA. Snow depth was not given in the original records except for the day with the greatest depth. 2 Quote Death To Warm Anomalies!

That was a La Nina year and is one of Los Angeles' top ten wettest winters on record, and I was wondering if that was a cold year for the PNW.

I would assume the arctic air made it south of the border on several occasions A low solar Nina for anyone keeping track of that type of thing.

No reason we shouldn't be excited about the prospects for next winter. I think the solar will be very low by this autumn.

TT-SEA Posted January 30, 2016 Report Share Posted January 30, 2016 Jim... is there any place online to find daily records from 1878 and 1889? I was looking for evidence of a warm spring in 1889. That year a strong Nino became a solid Nina. Then I came across this related to the Great Seattle Fire... pretty good evidence. But still want to see daily records from 1878 and 1889. I bet 1878 had a warm spring and summer. The spring of 1889 in Seattle had been beautiful. There had been little rain, and temperatures were consistently in the 70s. Unfortunately, the unusually good weather proved to be disastrous, as the dry conditions conspired with a handful of other elements to allow for the worst fire in city history. https://content.lib.washington.edu/extras/seattle-fire.html Quote **REPORTED CONDITIONS AND ANOMALIES ARE NOT MEANT TO IMPLY ANYTHING ON A REGIONAL LEVEL UNLESS SPECIFICALLY STATED** Link to comment Share on other sites More sharing options...

They are in a very rough excel format, but they give an idea of what happened in that time frame. Records from the Central Puget Sound are very hard to come by for the 1870s through early 1880s. I can probably email you the Olympia data if you want to IM me your email address. I sure wish I had ordered the Bainbridge Island microfilm when I had the chance. I have no idea how to get that data except for going to the Seattle Library and finding the monthly summaries in the PI microfilm which goes back to 1878. I did that for a few key months in that time frame. Pre 1890 weather records for this area are one of the few things that is still very hard or impossible to find online. At a rough glance March 1889 had a lot of 60s and April had a lot of 70s and even a low 80s. April looked fairly dry. 1878 had a cool, but very dry April and warm and very dry May.

snow_wizard Posted January 31, 2016 Author Report Share Posted January 31, 2016 Did the Puget Sound region get any snow with the late Feb 1890 blast? There was only 1 inch during the late month blast. There was 6 inches at mid month just before a lesser cold snap. The highlight of that winter was a 16" dump followed by bitter cold in early January. One hell of a winter! Quote Death To Warm Anomalies!

wx_statman Posted August 24, 2016 Report Share Posted August 24, 2016 That airmass in mid-January 1886 was a biggie. All-time record low of -57F in Edmonton, AB as well as -67F in Prince Albert, SK (only exceeded by -70F in that location in 1893, the provincial record low). This was also a legitimate Arctic blast for Portland, as seen in the downtown record. Quote Link to comment Share on other sites More sharing options...

I love seeing hand written notations on the old data forms. A good example is the Fort Klamath monthly form for January 1888, when they hit -39F. The hand written notes say it was the coldest reading there since -34F in February 1884. I would have never known about the 1884 reading if not for those notes.

WRT snowfall, its likely not even remotely accurate but the Olympia station had an outlandish number from the massive snowstorm of December 21-22, 1892. On 12/21 they recorded 3.67" of precip with a 30/25 spread and on 12/22 they recorded 2.39" of precip with a 29/25 spread. No snow data exists until 1896 though. Portland recorded almost 30" with that particular storm and I think Seattle had around 18", Olympia may have easily been 30"+. Quote Link to comment Share on other sites More sharing options...

I just hope NCDC can continue to fill the gaps in these station's histories so that we can get more complete records. Vancouver's online data technically goes back to 1856 (although their records actually began in 1849), but there is essentially a 40 year gap right now online even though plenty of the data itself exists. It's great to see Olympia's original station data filled and also downtown Seattle's recent inclusion back to 1893. Speaking of Olympia, another oddity about it (and several other spots) is that the current airport site actually began recording in 1941 but NCDC only archived the data back to 1948. You can see the 1941-48 data on NCDC's original COOP forms link http://www.ncdc.noaa.gov/IPS/coop/coop.html Would love to see all these types of gaps filled in the next few years.

Priest Point Park was a more representative lowland station than OLM, the latter being more prone to radiational cooling which obviously makes it stand out today. The minimums reflect this. The old Olympia station never fell below -2F (January 1888) while OLM has seen lower readings in less impressive events. The one that stands out most to me is -7F in January 1972. So its not even a fair comparison between the two stations. Quote Link to comment Share on other sites More sharing options...

The WRCC has been real screwy lately. They giveth and they taketh. On the one hand they're filling in some of the old city data, like the downtown stations for both Portland and Seattle. On the other hand they've inexplicably removed a bunch of daily records from different stations. This was discussed to some degree here on the forum during last week's heat wave, when there was confusion regarding record highs for Aberdeen. The monthly record table still shows the 105 degrees from July 1891 and August 1981, but there are no daily records above 100 in the database. It doesn't make any sense. They used to be there for all to see. The same thing is happening with Astoria Airport. You have to click on the monthly table to see that they hit 100 in July 1961, the daily records no longer reflect this. Speaking of the monthly record tables, they haven't been updated in four years. They all end at 2012, and none of them capture the backfilling of data that has occurred since that time. This is especially noticeable in Alaska, where daily record data has been backfilled to the early 20th century at many stations. But the monthly tables still cut off at 1949, which was the cutoff year for digitalization at many Alaskan stations prior to last year. RE: Airports. Same screwy business at PDX. They started recording data in May 1936. The WRCC has recently backfilled PDX to 1938, which is a weird year to pick. So now the WRCC shows daily records from 1938-1940 that aren't even reflected by the NWS, which still contends that official PDX records began in 1941.

The January 1972 low was snowcover magic mostly, the South Sound had the epic snowstorm with that and OLM had 18" on the ground (On another note that was probably the biggest snowcover gradient between Olympia and Vancouver that I can think of). 1983's -7F stands out more to me because they managed that with essentially bare ground, which makes it probably the lowest westside reading on record with an inch or less of snowcover. Granted, it was an historically cold airmass, but it's still remarkable how much colder they got than somewhere like Centralia with similar ground conditions.

Maybe they're still being updated, but I'm not sure why some of the daily records are disappearing. Totally weird. The PDX business seems semantics based now, since the official PDX station as we know it didn't come about until 10/14/1940. Prior to that, official records had been kept at Swan Island from 1928-40 and unofficial city data was recorded at the Portland-Columbia Airport from May 1936-October 1940 in a spot about a mile away from the later PDX site. I'm not sure why they decided to include the Portland-Columbia data at all, since it came from a somewhat different geographical location and it was literally a different station that didn't record official data. You can still find the 1936-40 obs on Wunderground, but it seems dubious to me that the NCDC would categorize it as "PDX" data. I imagine the same is true for a lot of these old airport stations, many of which moved around a few times so their starting histories becomes kind of a subjective affair when there's so many different points you could use.

wx_statman Posted August 25, 2016 Report Share Posted August 25, 2016 The January 1972 low was snowcover magic mostly, the South Sound had the epic snowstorm with that and OLM had 18" on the ground (On another note that was probably the biggest snowcover gradient between Olympia and Vancouver that I can think of). 1983's -7F stands out more to me because they managed that with essentially bare ground, which makes it probably the lowest westside reading on record with an inch or less of snowcover. Granted, it was an historically cold airmass, but it's still remarkable how much colder they got than somewhere like Centralia with similar ground conditions. You can add the -8F on January 1, 1979 to that list. None of those readings are representative of the western lowlands in any of those events. They mostly flaunt OLM's radiational cooling prowess more than anything else. It makes me wonder how cold the present OLM site would have gotten in some of those cold waves that Priest Point recorded. Like the -2F in January 1888...would OLM have hit -10F? Those are the kinds of questions I have, and that's what makes trying to compare the two sites a little bit frustrating. Quote Link to comment Share on other sites More sharing options...
wx_statman Posted August 25, 2016 Report Share Posted August 25, 2016 Are you sure about Alaska, it looks like a few stations are updated Juneau http://www.wrcc.dri.edu/cgi-bin/cliMAIN.pl?ak4100 King Salmon http://www.wrcc.dri.edu/cgi-bin/cliMAIN.pl?ak4766 Kotzebue http://www.wrcc.dri.edu/cgi-bin/cliMAIN.pl?ak5076 I do know that a lot of the stations east of us are screwy, anywhere in the SERCC domain gives you an error message now when you look at their history. Maybe they're still being updated, but I'm not sure why some of the daily records are disappearing. Totally weird.

RE: Alaska. That's exactly what I'm talking about. Look at Kotzebue for example. The daily records have been backfilled to 1897, but the monthly extremes table only covers 1949-2012. Look under General Climate Summary Tables on the left side and click on either Temperature or Precipitation. Those tables haven't been updated since 2012 and do not reflect the backfilling of data prior to 1949, nor any of the records set in the last four years. Its lame.

Agreed about PDX data. I've always known the official start month as October 1940. I actually didn't know that the 1936-40 data came from a different site than the present PDX. I've known about the data from Wunderground and always just assumed it came from the present PDX site, but wasn't considered official for whatever reason.

Yeah, good point about 1979, OLM actually only had a dusting on the ground for that too. We had decent snowcover down here with that event and only managed -2F. Of course then you have 1950, where OLM only hit -1F while many other spots flirted with -10F and lower. So it's pretty dependent on the event. The coldest westside low temp events of the 20th century like December 1919 and January 1930 may have been less impressive at present day OLM than some other places, although OLM definitely almost always trended dramatically colder than exposed Priest Point (about 7-8 miles away).

It looks like it moved a mile or so in late 1938, so the 1938-40 data would essentially be the same location.

Regionwide snowcover is a great equalizer it seems. The events of 1919, 1930 and 1950 had it in spades. December 2008 is a good example too...the coldest reading came from Arlington (-4F) and not OLM. Quote Link to comment Share on other sites More sharing options...
Front Ranger Posted August 25, 2016 Report Share Posted August 25, 2016 It's remarkable looking at how weak their December records are compared to January. And then contrasting that with modern day. And that January 1899 storm...wow. Two snowiest days on record, back to back.FYI, I wasn't meaning to compare Priest Park's numbers with OLM. Obviously, OLM is a better radiational cooling spot. I was referring to how much colder January's records were compared to December back then, and then seeing how much closer December has been the past 50 years or so.
