An upper level trough of low pressure (“U” shape on orange line) is setting up over the Pacific Ocean bringing more clouds and some cooling early next week, but for now short lived high pressure ridge (“Arch” shape on orange line) will keep us dry. The Perseid meteor shower peaks through Saturday, but the nearly full moon will probably spoil the show. You might want to give it a try anyway late tonight and Saturday night. Just make sure you are away from the city lights. A frontal system will approach the coast Sunday and move in Monday bringing the small chance of showers late Sunday night through Monday night. The weather will continue to be perfect for the Scandinavian Festival in Junction City and for the beginning of the Lane County Fair that starts next Wednesday.
