snow_wizard Posted December 5, 2014 Report Share Posted December 5, 2014 I'm working on a post about December 1871. Very fortunately there are records available from a number of places for that month. It appears everywhere from NW Oregon to Bellingham had a wickedly cold and very white Christmas that year. That month has always captivated me so I'm working on putting all of the data into a modern format. I have records for San Juan Island, Seattle, and Eola Oregon. Besides that I have the monthly total for Portland which was a nice 25 inches. Unquestionably one of the outstanding winter months on record for the region. I should have everything ready in a few days. 1 Quote Death To Warm Anomalies!

When all was said and done, Portland totaled 50.0" of snow with four separate major Arctic airmasses. It looks to have featured the most epic snowstorm on record for the San Juans. 40 inches (possibly more) for the month of December with a good deal of that between Christmas and New Years.

Had about 6" the day after Christmas so I was up to nearly 30" at one point. I remember that event being somewhat of a surprise. Of course I had no internet to look at, models, or weather forums. I just had the trusty weather radio, local mets, and The Weather Channel. I remember we had a dusting of snow on Christmas Eve, but the forecasts were really for maybe a slushy mix but that was it for after Christmas. It wasn't until Christmas night at my Grandparents for dinner when they had the radio on in the background, they announce a Winter Storm Watch for western Wa for the next day. I didn't believe it, but as soon as I got home I turned on the weather radio and The Weather Channel and got the same message from both at the same time. I did not sleep for the next 3 days! That was the first time I had seen that much snow in my area, it was quite epic!! I got nervous that day before the big snow as temps warmed up to the upper 30's and things started to drip, but by about 3pm the wind picked up and the temp fell like a rock, all the way down to 17 when the snow started that evening!

IbrChris Posted December 5, 2014 Report Share Posted December 5, 2014 The Army Signal Corps publication "Climate of Oregon and Washington Territory" gives a mean temp of 33.3 for Fort Steilacoom in Dec 1852 which is the value I've used. I'm guessing it's the mean of all three obs each day instead of just the "high" and "low" given in the spreadsheet (highest and lowest obs of the three each day).

snow_wizard Posted December 6, 2014 Report Share Posted December 6, 2014 One thing I would like to point out as far as cold weather is concerned is that both of our cold waves this season came with little warning in the models. In both cases the events began as shortwaves being shown about a week out that rapidly became more and more impressive as the time frame narrowed. The first thing to pick up on the last one was the CPC analogs. The MJO entering a favorable location was also a kind of indication. 1 Quote Death To Warm Anomalies!
