Seattle is known for it’s gray skies and rainy weather, but experts say the dense fog and temperatures in the 40s or 50s that have blanketed the city over the past several days is out of the ordinary.
Cliff Mass, a University of Washington Meteorologist writes on his blog, “I have forecast here for many decades and I can not remember a situation that is even close.”
The cause, according to Mass, is an odd combination of long-lasting high pressure, drought, and dense low clouds. In short, the high pressure on either side of the city is trapping colder air in the middle, close to the ground. The result? Fog, and lots of it.
The current foggy streak is standing at seven days. According to Seattle’s KomoNews.com that puts the current stretch in a seven-way tie for the fifth longest run in the city. The No. 1 spot goes to a 13-day streak from December of 1985. But according to local reports the current weather pattern could make a run at the record with the sun not in the forecast at least for the next several days.
Ironically the only thing that will wipe out the dreary conditions is a low pressure system; in other words a storm.
Such a system is on the way but is not guaranteed to hit the city. The earliest it will get there, if at all, is sometime next week. Until then Seattle will continue to see the same gray skies and dense low clouds.
Those in and around Seattle are making the best of the extraordinary conditions and sharing on Twitter:
For those who just can't take it anymore the sun isn’t that far away, at least geographically. Mass notes in his blog that while Seattle may be under a gray blanket the sun is shining and the air is warm just an hour outside the city.
