PORTLAND, Oregon — Showers will diminish and eventually end later tonight.
With a cold air mass in place, a clearing sky and light winds, the stage is set for areas of frost Wednesday morning. A Frost Advisory up for northwest Oregon west of I-5 for early Wednesday morning.
We see sunshine Wednesday, but clouds roll in during the afternoon and showers show up Wednesday night after sunset.
The showers end by sunrise Thursday. It will be a warmer day as the sky clears with highs in the mid-60s.
Another system approaches the coast Friday night. This will send showers over western Oregon Saturday.
Showers continue Sunday. Steady rain sets in Monday.
Have a great Wednesday.
