Oh no, this is not odd--this is what clay does! at least mine anyway...
I'd trade you my dry forecast in a heartbeat if I could Lee-Roy!
Here are some things I've learned the hard way about my clay soil:
If I disturb it wet or dry or inbetween, it disrupts the structure and takes several seasons for it to re-establish and this results in water pooling on any flat surface and evaporating from there, running off in most cases because I live on a slope, but either way *not* draining down into the root zone of my plants, which then languish and die from lack of water. I have a rod that I shove down into the soil around new plants to create channels for the water to drain down. I also create shovel-size channels in larger areas, around larger plants, for the same purpose.
If I disturb it wet--it dries into the worst, impenetrable, hard-pack, death-to-all-plants stuff imaginable. I leave it alone when it's wet; it is unmanageable goo at that point anyway.
If I amend the evil out of it, with tons of compost and grit, at a 1:1:1, everything is better, as long as I don't leave any clumps or layers of clay between good stuff. (so, for example, in the porch garden project this spring, my lean, mean digging machine dug out about 3-4' deep, all that was piled in the driveway; we threw all the big rocks in the bottom of the holes and put 1/3 of the clay back with amendments and I couldn't be more pleased with how the stuff if behaving and the plants are doing well
Of course, the pile of clay is about the size of a VW-bug and is still in my driveway growing a prodigious crop of sunflowers
but that's another story)
If I don't disturb the clay but keep piling decomposable stuff on top of it, eventually the top portion becomes plantable and the transition zone becomes less evil, such that when I do disturb it to plant, it doesn't take as long to restructure. If I bring up too much of that clay when planting and it melts and makes an impenetrable layer, I make channels and wait it out still.
Hope that helps
