Advisories: NONE AT THIS TIME.

The high pressure ridge (“Arch” shape of blue arrows) has moved to the east and we will continue feeling cool for the rest of the workweek and in addition an upper level low (“U” shape sliding southward from British Columbia) will be moving through the Pacific Northwest. A cold front moved through the Oregon coast falling apart as it did so cooling us down by a few degrees, then we’ll warm up a bit again through the weekend.
