While most areas ended up blank in the lowland snow department -- no small feat, considering how cold it got and for how long it stayed -- many did put up some impressive low temperatures -- including some single digits in Western Washington and below-zero temperatures elsewhere in the Northwest.
Seattle (at Sea-Tac Airport) bottomed out at 19 degrees on Dec. 7 while Arlington dropped to 9 degrees on Dec. 7 and Shelton made it down to 8 on Dec. 8. In Eastern Washington, Pullman dropped below zero for five consecutive days reaching -11 on Dec. 8.
The numbers, at least for Seattle, weren't all that close to a record. Without a layer of snow on the ground to help chill the air, the readings were a lot warmer than they might have been. We had 7 consecutive days at or below 32 degrees and the record is 24 set in 1947. We had 5 consecutive days at or below 24 degrees which was well short of the record 11. (Seven days would have got us into the Top 5.)
As for cold high temperatures, Seattle had one day with a high at freezing. As you can imagine, that is nowhere near a record. But just in case you were curious, the record is 10, set in January of 1969.
Here is a chart showing the low temperatures of several cities from the period of Dec. 4-9.
|City||Dec. 4||Dec. 5||Dec. 6||Dec. 7||Dec. 8||Dec. 9|
Long range models don't show any abnormally cold weather for the next 10-14 days so looks like we're done with the big chill for a while. I suppose that's OK -- check out what the extended cold did in Plano, Texas!
