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 west of the ridge) is moving through the Pacific Northwest. A cold front (position shown is Friday) will move through the Pacific Northwest Thursday. It doesn’t look like it will do much to change our weather except to keep us cool.
