Advisories: NONE AT THIS TIME.

An upper level trough of low pressure (“U” shape on orange line) off Vancouver will swing through today 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. The Perseid meteor shower peaks Thursday through Saturday, but the nearly full moon will probably spoil the show. Another frontal system will approach the coast Sunday and move in Monday bringing the chance of showers to the coast and Southern areas of Oregon.
