Insect and Spider Identification: Lawn full of spider webs, 1 by melody

I came home yesterday to see my yard completely covered in these tiny spider webs. The webs were floating through the air and covering the grass. I mow 3 acres and my yard was covered. The spiders had to be almost microscopic. I never actually saw one. What could have hatched out in such numbers? I\'m in far west KY, zone 7a. It has been been unusually dry and warm this fall. I have Encore azaleas still in full bloom and it\'s the middle of November. These are usually done by mid October, so the weather may have been some form of factor. I\'ve just never seen so many webs all at once. Any ideas?
