  1. I have to ask you this question so please be patient. I'm looking at the surface satellite photo. There are actually 2 Highs? The one below, is that the Eastern Pacific High? Then the one above over the Pacific Northwest that has been causing all of our problems. Correct? Correct me if I'm wrong that showed up around last August. Any idea when that might move? Thank you

  2. The high over the Pacific Northwest is a northward extension of the Pacific High. When is extends this far north it causes very dry weather with period of north winds in Northern California. The high will breakdown slowly over the next few days and by early next week we might see any showers but will be a lot cooler.
