Upper level low pressure (“U” shape offshore coming out of the Gulf of Alaska) is following behind another low that is moving away from us will be controlling our weather for the next couple of days but as it moves the slight chance of showers will disappear. Look for more sunshine and warmer temperatures returning Wednesday. There will be another weak frontal system (position shown on Friday) pushing through Oregon, but this one should be dry for the most part and only lower the temperatures a bit. The drying trend will last through the weekend and well into next week.
