More Fog, Sun, and Cold

The title pretty much sums up how our weather is shaping up for the coming week: fog in the morning, sunshine in the afternoons, and chilly temperatures throughout.

As for the rain, it’s going to be awhile. The latest models show our next chance at rainfall to be Saturday at the earliest–although a weak front does look like it will clip the coast Wednesday morning, tossing a few light rain showers around Forks, Aberdeen, and the like.

Why the all-around dull (but pleasant) weather? A large area of high pressure is currently parked over the eastern Pacific Ocean, at about 140 degrees West (in longitude-speak). This area of high pressure is diverting storms to the north and east of us, leading to our recent stretch of crisp and dry weather.

Since the ridge of high pressure set up shop off our coastline last Wednesday, Seattle has recorded a meager .01″–far below average for what is historically one of the wettest times of the year. The ridge has also led to some pretty strong temperature inversions around the area, making it rather difficult for the sun to poke through the extensive fog and low clouds that have socked in the metro area for the greater part of a week.

Look for continued cold at night—Seattle has fallen to freezing or below for the first three days of December, and tonight looks to be no different—and temperatures in the low- to-mid 40s through Friday, before a weak storm attempts to break down the high pressure ridge this weekend.

For those of you who like exciting weather, fear not–extended models show a return to a much more active weather pattern next week. Until then, pack away your umbrellas and break out the mittens and chapstick, as “dry and cold” will once again be the theme of our weather this week.
