The north/south precipitation gradient.

Unless your living in a rock/brainwashed by CNN or just totally wasted you'll by now have noticed for the last several years  an increase of a gradient where the storms do 90 degree turns and strike WA/BC hard but leave Oregon high and dry. It feels like we are no longer in the PNW anymore and California is going the route of the Sahara. 

Is this part of global warming (either natural or manmade?) or something else?

It's probably cyclical.  There is strong evidence of major SW US droughts in the past and some of them have probably nosed up into OR.

What do you think winters were like in general during those times?

Sometimes, but not very often, there is more rain to the south than the north.
