It's likely Paul going jogging a lot on days when we have a marine push. That's when we have higher pressure offshore and lower pressure inland.
As the air rushes inland overnight, it carries with it the cool, cloudy weather from the coast into the Puget Sound area. Sometimes, the clouds are thick enough to produce some drizzle or light rain until the midday sun starts burning off the cloud layer. So in these weather patterns, if you hate to jog in the drizzle, maybe go for a late evening jog instead.
