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, according to Yahoo News.
The site reports 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.
