I am getting the same thing here in NY. I think everyone was waiting for the rain. And now it's hurry, hurry it's getting late in the season. I will try to finish all of mine by next week, IF it stops raining.
Absolutely we are still aerating and seeding. It may start to get cool, but until the rains came, the soil was just to hard to get any penetration or good soil contact for the seed. This may be later than usual, but it had been much drier and hotter than usual also.
