Saturday's rain in the Pacific Northwest was the last wet weather for Seattle and Portland areas before midweek.
Cool high pressure building over the region will give rain-free weather, even some sunshine each day through today.
However, the high will also set up the I-5, I-84 and I-90 corridors for areas of late-night fog. The fog may linger well through the morning drive in parts of the Northwest and northern Great Basin.
In areas east of the Cascades and west of the Rockies, freezing fog is a potential add-on during one or multiple nights/mornings. Any freezing fog can make for slippery spots, as well as extra time spent deicing the windshield. In short, if it is foggy when you hit the road in the morning, there could be patches of clear ice as well.
Temperatures will generally stay above freezing along the coast, but there will be some exceptions. Most places over the interior will drop below freezing.

A northward bulge in steering winds high in the atmosphere, combined with high pressure at the surface will create conditions favorable for patchy fog formation the first couple of days this week. The pattern will break down later in the week.
An end to the rain-free stretch will come with a cold front, which should return wet weather to the Pacific Northwest later on Wednesday.
Increasing flow around that front and cloud cover over head will tend to break up the fog pattern.
