Forecast

The barometric pressure in Lebanon, Oregon varies throughout the year. It changes depending on the time of day and the weather patterns. Low pressure systems bring rainy and overcast weather. High pressure systems bring clear and sunny skies.

Lebanon is situated in the Willamette Valley. The valley is surrounded by mountains to the east and west. The Coast Range is to the west and the Cascades are to the east. These mountain ranges affect the air flow and pressure. They block or redirect air masses that move into the valley.

The surrounding landscape also creates a rain shadow effect. The air is forced to rise, cool, and condense, resulting in precipitation. This is why the climate is wetter than other parts of Oregon. Lebanon's weather is influenced by its location in the valley.
