Advisories: NONE AT THIS TIME.

An upper level trough of low pressure (“U” shape on orange line) off Vancouver will swing through Wednesday with more clouds. A short lived high pressure ridge (“Arch” shape on orange line) will follow and warm us up a bit. A weak frontal system will move in with no serious effect Friday with another frontal system coming through on Monday bringing some cooling.
