snow_wizard Posted January 14, 2018 Author Report Share Posted January 14, 2018 1-13- 1950 This is the day the infamous Friday the 13th blizzard stuck the lowlands of Western WA and NW Oregon. This is one of the few times large amounts of snow fell across the area with temperatures well below 20 degrees. Seattle would go on to achieve an impressive 24 hour total of 21.4". Their high temperature on the following day was a bone chilling 16 degrees which is the lowest max temp on record for Seattle during the 20th century. This storm was one of the few on record for Seattle to officially meet all of the criteria for a true blizzard. The 500mb map below is a composite of January 13 and 14, 1950. This is how it's done! Note: This is also proof positive that we can score big with a Hudson's Bay PV in play. 1 Quote Death To Warm Anomalies!

SilverFallsAndrew Posted January 14, 2018 Report Share Posted January 14, 2018 This date in 1971 was the final day of a 4-day snow event that dumped about 36" of snow at Silver Falls. This was one of the snowiest winters on record not only at Silver Falls, but also in parts of the Willamette Valley. I am sure others know more about this setup, but I believe it was a very cold onshore flow event similar to February 1990. In the valley it was a very wet snow event, but a very significant snow event. Here are some totals for the valley ending the 14th.

BLI snowman Posted January 15, 2018 Report Share Posted January 15, 2018 Mid January 1888 was perhaps the most intense arctic airmass in recorded history in the PNW. After an impressive early month airmass (21/10 at Portland), a front came barreling in on the 13th and the temps grew progressively colder for the next few days before bottoming out on the 15th-16th. Temp spreads include 23/-3 at Ashland, an incredible 20/1 at Newport on the coast, 13/-5, at Eola, all time records of 9 and -2 in Downtown Portland (with bare ground!) on the 15th, a 16/10 day at Astoria on the 16th, and all time records of 18/-2 at Downtown Olympia. East of the Cascades the airmass was phenomenal, Spokane set all time records on the 15th with a high of -10 and low of -30. Miles City, MT plunged to -65 on the 14th, still a record for that part of the state, and the historic blizzard that hit the plains with this arctic front was the deadliest in American history. The cold wave lasted for several days before a fairly significant overrunning snowstorm moved in on the 16th-17th. The late part of the month featured a pretty impressive blowtorch. 1 Quote Link to comment Share on other sites More sharing options...

Scott Posted January 17, 2018 Report Share Posted January 17, 2018 Mid January 1888 was perhaps the most intense arctic airmass in recorded history in the PNW. It hit the Rocky Mountains too (the Montana reading was already mentioned), though there weren't many weather stations around then. The book History of Rich County (Utah) says that Randolph hit -65 on 1/15/1888. I have always wondered about that reading. Randolph is one of the coldest places in Utah, but besides that -65 mentioned in the history book (apparently unofficial since I have never seen any other data indicating that it is the state record), the coldest reading in a town in Utah was -50 at Woodruff on 2/6/1899. I have looked for, but have never found any other information or sources on the -65. Since Randolph is a very cold spot (one of the coldest in Utah), I have wondered if the -65 could actually be accurate given the severity of the 1/1888 cold snap. I guess I could see it under ideal conditions during a severe cold snap. Official records in Randolph only date from 1893-1894 and then again (with much missing data) 1997-2017. In the same general region, Border Wyoming produced a -60 on 2/8/1929 and Maybell produced a -61 on 2/1/1985. Maybell and Border both have similar climates to Randolph. It is true that Randolph didn't get as cold as Maybell during the 2/1985 cold snap, but it has with several other cold snaps. Near the river and under ideal conditions, I guess I can see that the -65 might have some plausibility. I don't think there's any way to verify or confirm it though.

The heatwaves of the late 1930s and 1940s became very humid, however, with dewpoints twice reaching 88*F during those swampy 1940s summers.

TT-SEA Posted January 18, 2018 Report Share Posted January 18, 2018 Proof that the 4th of July in 1910 was a beautiful day in North Bend. Actually I looked it up and it was 81 degrees here on 7/4/1910. Seems way too warm to be wearing these clothes! It had been basically summer-like since April 15th in 1910... that was an absolutely gorgeous spring and early summer. These people had already experienced almost 3 months of summer before this picture was taken. For those familiar with Mt Si... it sure does look bare. I believe it was logged and then there was a massive fire in the Snoqualmie Valley in 1913. They really mismanaged things back then.And here is a later photo looking south towards Rattlesnake Ridge which is completely mangled. Our house would on the left side of this pic on the side of the ridge. I would say it looks infinitely more scenic today!

wx_statman Posted January 18, 2018 Report Share Posted January 18, 2018 For reference, the next coldest reading in the Missoula signal service record (1870-1893) was -36 on 2-3-1883, and that was an absolute minimum. Only 3-daily obs were available in January 1888, implying even colder readings (at least possibly) outside of the 7am observation times. The lowest 7am reading outside of January 1888 was just -34 in January 1875, itself a massive cold wave. Really hard to believe three straight days pushing -40...but I guess it's possible.

wx_statman Posted January 18, 2018 Report Share Posted January 18, 2018 I'm not sure if I've posted the temperatures from Fort Walla Walla from January 1862 or not. Here are the temperatures from a 7 day period where they were continuously below zero. In Walla Walla this is insane! 13. -3/-1014. -4/-515. -3/-1616. -11/-2417. -15/-2418. -6/-2019. -4/-8 Incredible month. 10 different days had 2pm temps below zero in Walla Walla.

snow_wizard Posted January 18, 2018 Author Report Share Posted January 18, 2018 This thread makes me sad. We just need to get our winters to focus in January again. I think we will, but when is the question. Quote Death To Warm Anomalies!

BLI snowman Posted January 18, 2018 Report Share Posted January 18, 2018 Meant to reply a couple days ago. The Missoula numbers were insane in January 1888. 12th: 27/-1013th: -14/-2814th: -25/-3915th: -29/-4216th: -27/-4017th: -6/-2218th: 20/5 I mean, those are really hard to believe. I want to believe them but I'm thinking something was off. I don't know, I'd wager that the lows are fairly close to accurate. A high of -29 does seem pretty extreme, although a high of -10 at Spokane would probably support highs around -20 for Missoula. That airmass really was pretty off-the-charts from the looks of it.

Phil Posted January 18, 2018 Report Share Posted January 18, 2018 When you and I are 70?When the WPAC warm pool/ITCZ starts migrating S/SW again, along with the Hadley Cell. That entire system has been migrating N/NE since at least the early 19th century, probably since ~ 1700.

It's pretty obvious there are shorter term cycles within the longer cycle though. 1 Quote Death To Warm Anomalies!

Phil Posted January 18, 2018 Report Share Posted January 18, 2018 It's pretty obvious there are shorter term cycles within the longer cycle though.Definitely. And these longer term cycles (perhaps the Pacific component of the more well-known Bond cycles) typically complete their neoglacial warming phases within a span of approximately 300yrs +/- 50yrs, which is about how long this one has lasted. So, statistically speaking, it should be ending shortly. I’m just not sure whether the best way to terminate it would be via an amplified ENSO, or a dormant one. I suspect a very active ENSO is utilized by the system when it’s trying to warm to equilibrium, vice-versa for a dormant ENSO, which appears more frequently during cooling periods. But, whether the bond cycles reflect the thermodynamic system’s equilibration, or whether it’s the othe way around, and the thermodynamic system attempts to equilibrate to said bond cycles as if they’re some sort of fluid/inertial resonance, isn’t clear to me. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

SilverFallsAndrew Posted January 18, 2018 Report Share Posted January 18, 2018 6 years ago on this date I had 5.38” of rain fall, this fell on top of 26” of snow depth which had about 4.5” of snow/water equivalent. The result was massive small stream flooding in the Central Willamette Valley. 4.02” of rain fell at Corvallis. The communities of Turner, parts of South Salem, and Albany experiences the worst flooding. In Albany two people drown when their car was swept away in a grocery store parking lot when a small stream over flowed its banks. There was not widespread mainstem river flooding, but the Willamette did crest above flood stage at Salem and Albany.
