Since we're talking about January 1868, here's a copy of an old post I made about that month:

 

**************************************************************************

 

Here is the ridiculously cold January 1868 at Albany. This was one of the coldest months in PNW history, right up there with January 1862, and also featured one of the greatest cold waves on record. This month appears to have averaged between 22-25 degrees in most lowland areas of the I-5 corridor. Eugene fell to -15 during this month (on the 10th), and there was 3-4 feet of snow in Hillsboro according to one source I've seen. 

NOTE: The following max/min data is derived from 3-observation daily logs (7 am, 2 pm, 9 pm), so the real high and low temperatures are not known. There could be a significant difference between the real 24 hour max/min data and the 3-observation-derived data that is shown, so keep that in mind. But to get a general idea of where things were, this obviously does the trick!

1/01: 50/39
1/02: 56/35
1/03: 37/33
1/04: 33/25 4" snow
1/05: 33/22
1/06: 23/13
1/07: 19/10
1/08: 24/20 4" snow
1/09: 29/6
1/10: 30/-4 
1/11: 19/-6
1/12: 21/7 
1/13: 28/16
1/14: 39/26 3" snow
1/15: 28/24
1/16: 22/10
1/17: 25/4
1/18: 24/2 
1/19: 26/0 1.5" snow
1/20: 30/21 1.5" snow
1/21: 42/30
1/22: 36/22
1/23: 40/10
1/24: 30/28 missing snow data, but there was 0.75" of precip
1/25: 36/31 4.5" snow
1/26: 36/22
1/27: 32/18
1/28: 36/13
1/29: 30/8
1/30: 34/12
1/31: 32/11

-24.0 monthly average
-At least 18.5" snow, plus the one missing day that had either heavy snow or freezing rain, or both. 
-Minimum of -6 observed at 7 am on the 11th, but the real minimum may have easily been -10 or lower between the observation times. Recall that Eugene bottomed out at -15 in this event, on the 10th. 

 

 

Yeah, that winter was basically 1861-62 lite for sustained cold. It started at the end of December and lasted well into February. Much drier though with the cold for the most part.

 

I don't think the 3-4' report at Hillsboro is quite accurate, although The Oregonian did report a few inches near there on the ground in mid January while Portland still had bare ground. There were also a number of 2-4" type snowfalls that winter in the Portland area amidst all that cold, but nothing major.

Oh interesting. Who knows. Either someone fibbed or it was a report from further west with some elevation.

2014

 

Record warmth in western N. America. Port Orford hit 79 degrees on 1-25-2014, just missing the state record high for Oregon for January (80 in Brookings on 1-28-1984). Bandon tied its monthly record of 75 degrees. In Alaska, upper 50's surged into the Anchorage Bowl. Palmer hit 57 degrees, smashing its monthly record of 52 from 1961, and Palmer Airport hit 58. In the interior, Big Delta hit 50 degrees - not a monthly record, but remarkably the 4th time in 7 years that Big Delta hit 50 in January (2008, 2009, 2011 and 2014, monthly record of 54 set in 2009). Since records began in 1942, Big Delta had never exceeded 48 degrees in January until 2008.

 

Truly phenomenal warmth overspread NW Canada. Fort Nelson, BC soared to 59 degrees (14.9c), shattering its monthly record of 51 (10.7c) from 1-19-1981. Another station in Fort Nelson hit 60 degrees (15.3c). In the Yukon, both stations in Burwash - town and airport - reached an unfathomable 62 degrees (both at 16.5c). These are the highest January readings in Yukon history as far as I'm aware. For the Burwash town station, the previous January record had been just 49 degrees (in 2009). However, a similar freakish surge of warmth hit Alaska/Yukon right before Christmas in 1999, providing some historical context to January 2014 more than the previous January record could provide. Burwash hit 56 degrees (13.5c) on 12-22-1999, the previous highest reading in the entire Nov-Mar period. As an aside, numerous monthly records had fallen in Alaska during the December 1999 event, with readings well into the 50's in the interior. Dry Creek hit 60 on 12-22-1999 in what may have been the warmest reading in interior AK history during the heart of winter. 

 

Back to January 2014, Fort Liard hit 61 degrees (16.0c), representing what was likely the highest January reading on record for the Northwest Territories. As with Burwash, the previous January record was significantly lower at 49 degrees (in 1985). Another station in the downslope zone of western NT, up against the topography near the Yukon border, recorded an even higher reading - Wrigley hit 63 degrees (17.0c), but I'm not sure how reliable this particular reading is. It may very well have been accurate. All the way up at 70N latitude, Cape Parry hit 39 degrees (4.0c). This station has records from 1957-2002, and the previous January record was just 30 degrees in 1981.

 

2015 (encore)

 

On the one year anniversary of the previously described record heat, Eugene soared to 68 degrees on 1-24-2015. This broke the January airport record of 67 (in 1975 and 2005), and just missed the city record of 69 from two torch-tastic Nino's (1914 and 1931). A couple days later, Newport hit 72 degrees, the probable January record for the city. This reading was recorded at the new COOP located 3 miles north of town. The previous long-standing COOP (which stopped recording in 2010) had never exceeded 69 in January.

 

Government Camp hit a ridiculous 70 degrees, shattering the monthly record of 63 from 1994, 2013, and 2014. It was the 3rd straight January with a monthly record high at G Camp. The 70 degree reading also exceeded the previously untouchable mid-winter record of 69 from 2-1-1962. Not to be outdone, Santiam Junction hit an other-worldly 72 degrees on 1-26-2015. Temperature records at Santiam Junction only date to 1986, but the previous January record was just 62 degrees - set in 2014. The warm air spread east of the Cascades, and monthly records of 71 degrees were set in both Bend and Condon. At both locations, the previous January records had been 67 degrees (Condon in 1939, Bend in 1971).

Two cold snaps hit the Rocky Mountains on January 31-February 1 in both 1951 and 1985.   Here are some records and temperatures.  There weren't as many records set as during the cold snap of February 1989 or December 1990, but some of the ones that were set were quite impressive.

 

1985

 

1/31/1985

 

 -65 at Peters Sink Utah.   I believe this was the forth coldest reading recorded in the Lower 48.

-51 at Sage Creek Ranch Utah.  This is probably the coldest temperature recorded in Utah that was recorded in a place where someone lives.    Apparently it isn't official, though very plausible given the location (Sage 4 NNW Wyoming a few miles away also hit -51 the next day).

 

2/1/1985

 

-69 at Peters Sink.   This was the 2nd coldest reading in the Lower 48.

-43 at Randolph Utah.

 

-51 at Sage 4NNW Wyoming.

-46 at Fontenelle Wyoming

 

-38 at Idaho Falls Airport.

-33 at Pocatello Idaho.

 

-61 at Maybell Colorado (which happens to be just west of where I live).  This was the coldest official reading ever recorded in Colorado. I believe that it was also the coldest temperature in the world ever recorded that close to the equator.

-60 at Taylor Park Colorado.  Ties for the 2nd coldest temperature in Colorado.   The other two times where -60 was recorded were 1/1/1979 at Maybell and at Taylor Park, also interestingly also on 2/1/1951.  Taylor Park is in the southern part of Colorado and I believe that this was the coldest temperature in the world ever recorded this close to the equator.  

 

1951

2/1/1951
 

-41 at Fort Collins Colorado.  I thought that this was the coldest temperature ever recorded in the Eastern Plains of Colorado, but it appears that Greeley hit -45 on 2/12/1899.

-27 at Colorado Springs Airport.
-60 at Taylor Park Colorado.

On this day back in 1937, Portland ended up with 16.8 inches of snow from a monster snowstorm that started on January 31 and ended on February 1. Huge snow drifts blocked roads in northern Oregon and the Cascades mountains passes. Here is a picture of the aftermath the next day in downtown Portland at SW Broadway and Alder Street.

Right now in 1989 there was a huge graupel shower which triggered a flash freeze with strong northwesterly winds.

That pattern actually was triggered by a #SSW. One of the most prolific SSWings ever recorded, actually.

Perhaps it doesn't quality as a major event, but my house was -48 on 2/2/2011.   This is the coldest I have been out in, so I guess it is a "major weather event" for me.  Oklahoma also set their state record then, but I don't know if that qualifies as the West.

Feb 6 and 7 of 2014.  An amazing storm and one I will never forget.  I was on the coast at the time as Tillamook and Pacific City racked up 6" on both days.  Was absolutely incredible and watching the models converge on it was truly remarkable.  They weren't even hinting at a snowstorm 3 days out as most of us in the NW just expected a dry cold, but ho boy was that one something else.  Exciting northerly flow in the valley, and mesmerizing easterly flow at the coast.

The thread seems to have died, but February 5-7 1989 was one of the most severe modern cold snaps to hit the Western US.

There are too many to list, but here are some that are applicable to where I lived at the time or live now.

 

Salt Lake City (where I lived at the time) hit -14, which is the coldest temperature recorded there within my lifetime.   The coldest temperature in a town in Utah during the cold snap was -47 at Roosevelt.

 

Craig Colorado (where I live now) hit -51 at the official weather station.  Some employees at CDOT went down to the Yampa River Bridge on that day and recorded a probably accurate, but obviously non-official -65.

 

There were other impressive records set in all the Western States.   Hopefully others can post some too.

Coldest February day on record at DEN on 2/4/89, with -9/-16. The next morning fell to -24. The -9 is tied with 1/11/63 as the coldest high in Denver history.

February 9-10 1933:   A historic cold snap for the West.

 

There are too many records to list, but here are some of the more impressive ones.

 

-30 at Salt Lake City Utah 2/9/1933

-66 at West Yellowstone Montana on 2/9/1933

-63 at Moran Wyoming on 2/9/1933

-54 at Seneca Oregon on 2/10/1933

 

It isn't quite the West, but there was also a -23 at Seminole Texas on 2/8/1933

 

February 10 2017:  A historic heat wave for the Rocky Mountains (and probably other areas as well).

 

80 at Denver on 2/10/2017

 

I missed this posting this one a few days ago:

 

February 6-7 2015:   A historic heat wave for the Rocky Mountains (and probably other areas as well).

 

68 at Salt Lake City on 2/6/2015 and 2/7/2015 (earliest temperatures recorded this warm)

61 at Craig Colorado Airport on 2/9/2015.   The previous January record was 55 and the next earliest warmest temperature was 62 on 3/8/1986.

74 at Denver on 2/7/2015

I missed this yesterday but feb 8-9th 2017 was the worst ice storm I’ve seen here. We don’t often get much freezing rain here. We generally transition from snow straight to rain.
