What Part of Oregon are you in? East of the Cascades, Madras, Terrebonne, Bend areas the wood should dry pretty quickly in that low humidity. Heaven help you if you're a neighbor of mine, in the Brightwood area, I've read that Brightwood is THE Wettest spot in the state, and Unfortunately, I believe it .
I also recommend splitting down to your preferred burn size as soon as possible, it will dry much faster when split.
With any wood, the drier you can keep it the better, also as much air flow as you can will help drying and avoiding rot, that is a balancing act between how much room you have for seasoning wood, and how much wood you have.
One quick, simple cheap way to store firewood is on old pallets, use some metal "T" fence posts for end posts, and a tarp. Stack the wood a bit higher than the fence posts, so they don't tear your tarp. It helps if you use some rope and tent stakes to pull the bottom edges of the tarp out away from the wood, to let it "Breathe" and get good air flow, that will also shed any rain water a bit further away fro the wood pile.

Hey Doug, I know Brightwood yes I do. Well I'm not sure about Brightwood being the wettest spot in Oregon but what I do know is that we are in the Coast Range about 28 miles NW of Portland and area is classified as a temperate rain forest - and maybe that classification extends to the west slopes of the northern Cascades. Lots of moss, ferns, mushrooms, salamanders, frogs, etc. My weather station is reading the outdoor humidity to be 96% at this time.
I have been using old pallets as well. Instead of metal posts I have been putting additional pallets on 2 sides to lean the wood against tying them together with a 2x4 and then a tarp on top with old double hung window weights zip-tied to the corners and sides. It has been working okay so far. Whenever I have a dry day I try to remember to uncover the wood so it can air out. With the pallets on the sides it seems to help ventilate the wood.
I just picked up a cord of maple that has been sitting in someones yard in Beaverton for the last 2 years and the owner posted it on Craigslist. Aside from the pieces that need to dry out from being at the top of the pile or on the ground at the bottom, I have been burning some of it. I love this Maple! It makes the Alder look like wet leaves. I pretty much have access to all the Alder I want and then Fir but this Maple is so much more than either for burning in my furnace. It burns long and makes great coal beds. If I burn Alder alone, I end up having to relight the fire every couple of cycles because it just doesn't seem to make good coals as well as not burning long. It is the worst "hardwood" I have dealt with so far.
I hadn't thought about the tent stake idea, I might need to try that. We get some serious winds up here at 2000 feet so I have to be careful not to provide a place for the wind to take hold.
