A weak trough of low pressure is moving through Oregon and California bringing more clouds, but no precipitation. A cold front will slide through between tonight and Tuesday having almost no effect on our weather. A high pressure ridge (Shaded “Arch” shape with blue arrows over the Gulf of Alaska) will move onshore bringing more sunshine to the Pacific Northwest by midweek.
