Is Sequim Really Sunnier?

A frequent question is have gotten is about Sequim. Sure it is dry..but is it sunnier. The answer is probably yes..and today (Sunday) is a good example. First start with the weather radar below. World-class rain shadow northeast of the Olympics ! Now look at the high-resolution visible satellite image--and examine it closely. You can see a break in the clouds NE of the Olympics....some sun was clearly getting in there!

Want some ground truth? Look at the cam at the purplehaze lavender farm in Sequim...pretty bright! I have include two other Sequim area cams to show that the ground was dry and there was clearly breaks in the clouds.
Finally, look over the surface chart (the last figure). The winds are plotted at a number of stations (the pennants are pointed in the direction the winds are blowing). Do you see the eddy NE of the Olympics? That is, the winds are going in a circle...with calm winds in the middle. In contrast, the winds are blowing strong from the SE over Whidbey! Sequim means "place of calm waters" in the native american language...and they knew what they were talking about...the wind can be light in the middle of the eddy...thus calming the waters.
