The Northwest and Great Britain have both had soggier than average summers-any connection?
Yes. Keep in mind the weather we experience at or near the surface of the earth is greatly influenced and directed by winds higher up in the atmosphere, which 'snake' around the globe. A southward 'dip', what meteorologists call a 'trough' has been very persistent over or near the Pacific Northwest. A similar feature has been persistent over or near Great Britain. The persistence of this flow pattern in the upper atmosphere is also responsible for maintaining a large ridge of high pressure over much of the eastern 2/3's of the United States, which in turn has led to a very hot, dry summer. So the trough over the northwest and the one over or near Great Britain are definitely related.
