This tracks for us in Vermont. It's barely rained since early July, and of the trees in our yard, the birch is damn near bare, the oak is starting to drop, and the maple is just holding on to its leaves. In the wider area I drive in, the trees are starting to show some color.
We're looking forward to some rain this week, but we're a ways behind[0]. If you have New England fall foliage plans, you might want to move them up if you can.
