[NAFEX] Black walnuts dry in shell

I started cracking some of my black walnuts and they're all shriveled, dry, and black. Inedible. Anyone have any ideas on the cause of this? The summer has been very dry but the walnut tree is large and the water table is not that deep. Last summer was very wet and they were also somewhat dried, but still edible and not blackened. Something wrong with the tree? Late frost (as suggested by Jerry H., although I would think late frost would prevent fruits from forming, not filling out)? All suggestions entertained.
