Here is my weekly weather quiz question. “What is a “Rip Current?”
____________
An Upper Level Low Pressure Trough (“U” shape ) is moving away from us as weak High Pressure tries to replace it. The graphics for days 1-3 show the frontal system that moved through Oregon Wednesday. The graphics for days 3-7 Sunday through Thursday show a cold front that will push into the Pacific Northwest between Tuesday and next Wednesday.
Note: The weather looks pretty good for the Memorial Day Holiday weekend. The only chance of a little rain seems to be Friday night and during the day Saturday. That means Sunday and Memorial Day should be bright and dry.
