An  upper level High Pressure ridge (the “arch” shaped portion of the yellow lines) is slowly moving away from us. A trough of low pressure is slidding down from the Gulf of Alaska and it will move eastward just to the north of us. That will increase the onshore airflow and cool us off some more . A cold front will drop down from the northwest mid to late in the week and it looks like it will have little or no effect.

A stronger  upper level High Pressure ridge (the “arch” shaped portion of the yellow lines over the Pacific) is moving toward us and will switch our airflow from onshore to offshore warming us up quite rapidly. Most locations in the valleys will see 90 degrees and  above this week as a result of that strong high pressure ridge. It will cool a bit but still be very warm and dry this weekend for the Oregon Country Fair.
