Well, there was also one spotted in Hillsboro, too, far from the coast. According to Wikipedia, cold air funnels are common here in the spring. This is what Weather Underground had to say:
The air mass over northwest Oregon and southwest Washington is cool and unstable today due to the recent passage of a cold front. This pattern can produce cold air funnel clouds. These funnels do not usually touch the ground. However... if they do touch the ground they are dangerous and can be damaging.
The threat of funnel clouds will continue until sunset... when the atmosphere will stabilize due to the loss of daytime heating.
