As weak front approaches the Coast later today scattered showers will try to develop along the coast and even a few in the valley. Isolated t-storms are possible over the Cascades and points east. . This means shower chances increase this evening at the Coast and overnight inland. There’s a better chance of showers Tuesday. Highs will be in the low to mid 70s Tuesday.
A stronger cold front brings rain and breezy conditions overnight Tuesday into Wednesday morning. We could see a .25” to .50” of rain in the Willamette Valley. Along the Coast, rain totals may top 1”. SE winds will also increase especially along the coast where gusts to 40mph are possible. Steady rain early Wednesday switches to showers and sun breaks. . Cooler air will move in behind the main front and some of our highest elevations may see some snowflakes mixed in.
