Advisories: NONE AT THIS TIME

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