Rainfall is not too far away for the Pacific Northwest. A bunch of moisture across the Pacific Ocean shall blow into the state late Friday and through the weekend. The coast will see the brunt of the moisture and northern locations will get more rain than southern.
The Umpqua Valley is facing rain as well, though a smaller chance. Tonight will be dry under mostly clear skies and lows in the lower 50s. Friday begins under mostly sunny skies, but expect partly cloudy conditions by the afternoon. Showers should develop as well, but they should be isolated in nature and more common to the north than the south. Saturday may see spotty rain and highs in the mid to upper 70s. Come Sunday, sunshine will return to the area.
In the Willamette Valley expect partly cloudy skies through the night with lows in the upper 40s. Friday will start dry under partly cloudy conditions. Heading through the day, cloud cover will increase and showers may begin to fall in the late afternoon and early evening. High temperatures Friday afternoon will be in the mid 70s. Saturday is looking wet. Rain will be off and on, meaning there will be plenty of dry periods throughout the day, but showers are expected. Temperatures will be a touch cooler as well, highs should hover around 70 degrees. A bit of rain is possible Sunday morning, but by the afternoon drier weather will prevail.
On the Oregon Coast the next few days will be wet. Tonight’s lows may drop to the mid 50s under mostly cloudy skies. Friday showers will begin moving in from the ocean. Daytime highs will be around 70 degrees. Saturday will see more rain as well. A few dry periods are expected, but it will be more wet than dry. Sunday will wake up to rain but by the afternoon drier weather will move in. Highs on both Saturday and Sunday should be in the mid 60s.
