That upper level low pressure center (shaded area just offshore) is staying off the California Coast and sending moisture up from the south. Thunderstorms will continue to develop in the southern reaches of Oregon and slowly move northward. These storms will build in the mountains and foothills, but could still wobble westward and bring the valleys a slight chance of  noisy weather for the next few days. Temperatures will be about normal for this time of the year which is a lot better that the 100+ temperatures we had last week.
