Advisories: NONE AT THIS TIME

A weak trough of low pressure has moved through Oregon and California bringing more clouds, but no precipitation. A cold front slid through having almost no effect on our weather, but it will clear us out tonight and allow the low temperatures to get much cooler. A high pressure ridge (Shaded “Arch” shape with blue arrows over the Gulf of Alaska) is moving onshore bringing more sunshine to the Pacific Northwest for the rest of the week into the weekend.
