We are off to western Oregon for this evening’s forecast. It’s a part of the world that has been getting pounded by a pipeline of moisture from the Pacific. How much more is in store for Corvallis?
At 335PM, PT, Corvallis was reporting a temperature of 35 degrees with overcast skies and fog. The thatch of thick fog continues to fill the valleys of the northern Oregon Cascades, but actual precipitation has evacuated the region. A surface low over northern California is continuing to press to the southeast, taking any rain and snow inland, but no scouring boundaries means the lower level moisture will remain for Corvallis.
Of course, it doesn’t help that there is an area of persistent low pressure over the Gulf of Alaska. A particular wave is moving into British Columbia, and the resultant westerly flow at the south end of the wave will reinforce moisture over western Oregon. This means fog and clouds tomorrow morning, with rain developing again in the afternoon as the wave works inland. Another, stronger wave will move into the area late on Tuesday. This will bring much heavier rain through mid week in Corvallis, with the first samplings of this next round of precipitation arriving Tuesday night
