Thicknessing

This past August I was able to acquire free oak from a neighbor. I’ve never sawn or split small logs before, so I used an axe and log saw to halve them. I’ve also never seasoned wood before so I’m letting the halves dry in my garage. My garage is not insulated nor heated. I live in the USA in Pennsylvania, where January and February months sometimes reach minus two degrees. In the summer, like August, temps sometimes reach 100 degrees. In my garage, I’m sure the temp is probably 105 or close to 110 degrees. I’m sure the changes in these temperatures will cause the log halves to badly check and crack and therefore make them useless. My only solution as of now is to saw the logs and plane them to one and half inches thick. Once I get all the log halves to this thickness, will they properly dry when I want to plane them to final thickess? I’m asking because I was anxious to see how well one of the smaller logs would plane and the wood feels slighty wet. The plane works fine but I’m concerned that the wood will still be wet in a couple years when I try to plane it down to 3/4 of an inch or 1/2 an inch.
