All of the trees seem to be having a bit of a problem this year, likely due
to hot weather and a lack of rain I'm thinking. I was just curious if
anyone else has experienced any similar issues, especially with their black
walnut trees.

We saw this last year when we had a drought. It is natures way of
conserving moisture in the tree. The leaves have served their main
purpose to produce nuts. Now it is stocking up sugars in the roots to
form next springs new leaves. Black walnuts show this behavior quite
frequently here.
