Good morning – yesterday, from a distance I saw yellowing occurring on my Prunus x Okame. I got closer and took several photos – the yellowing leaves are loaded with black spots. The yellowing / black spots is not happening on the entire structure but I’m assuming it is spreading. I have 3 of these trees – 2 of the 3 seem to have the same malady, 1 not so much. I’m in SE PA – there has been about 2 inches of rain in the last 14 days – 14 day temps avg high 82 low 60. I included a photo from Aug 8 and the trees did not appear to be yellowing then although the photo is from a distance. Any help with identification is greatly appreciated.

Next photo from August 8
