The satellite image was taken when the leaves were off the trees.
I have looked at some ground photos of your location by Google and Bing showing trees that might interfere with TV reception. Please see the PM I sent to you.

Trees and UHF

As for growth of trees, I live in a mature neighborhood and I can't imagine there has been any significant tree growth that could be suddenly causing these issues.

Trees keep growing every year. I suggest you wait to see what happens when the leaves are off the trees.

If there are any other photos that might help diagnose the problem, just let me know and I will happily accommodate.

A photo looking from the rear of the house toward 125 true/129 degrees magnetic might be helpful.
If the antenna were moved a little down south in the attic, it might aim between the two largest trees in the SE. That might be difficult with your big all-channel antenna.
A UHF-only antenna would be easier to move around in the attic, but you would still need a VHF-High antenna for WBBM CBS on real channel 12.
Another possibility would be an antenna outside that aims below the lower branches, or an outside antenna aimed between the trees.
