Seattle's chilly winter accomplishes something that hasn't been done in nearly 5 years
We finally broke the streak!
With extended cold snaps in December and January, both months ended up cooler than normal by average temperature.
It's the first time since June-July 2012 we've had consecutive months with a cooler than normal monthly average. December's average was 38.0 degrees and January was just a tick lower at 37.9 degrees.
In between, it's been a relentless warm stretch, with super Godzilla El Ninos and The Blob setting monthly records left and right.
Seven of our 12 months now have set their all-time warmest monthly records in the past three years, with January and September the only months to not register a month in the Top 5 since 2013. Heck, each of the last four Augusts have been in the Top 5 warmest on record.
Average temperature at Sea-Tac Airport:
Bold = Top 5 warmest month
Bold+asterisk: Warmest month on record
Will February make it three in a row?
February is set to begin with a few chilly days before a change to a warmer pattern toward the end of next week. And if you want to run with the NOAA long range climate maps, they seem to think beyond that, it'll remain warm enough that February will break the short cool-month streak, giving slight odds for a warmer and better odds for a wetter than normal month. (Although they continue with a La Nina-weighted cool/wet forecast for February through April as an entire average:)
Hopefully if nothing else, at least the wetter forecasts should bring some fresh snow to the mountains. Seattle had just 11 days with measurable rain in January -- the fourth lowest on record at Sea-Tac.
