need to id this weed
Could you pull some of it with the roots and ground level growth. Zoom in close. and lay the grass on a white sheet of paper. It's almost impossible to see from these photos. When were these photo made?
It is tall fescue, I had the same situation with in the last two weeks. Looks like hell. Check the link below, it is perfect for this weed id.
Also this is taken from Purdue Extensions Turf Tips.
"Do-It-Yourselfer: Is it Crabgrass or Tall Fescue?
We have received a number of calls this year about trying to control the crabgrass running rampant in lawns. It's a much more coarse bladed and lighter green than the rest of the grass, so it must be crabgrass? It's not crabgrass and is more likely tall fescue. Though crabgrass and tall fescue may look similar in summer, they are easy to distinguish now. Crabgrass is a summer annual and will only start to germinate in mid-April or later in Indiana , so it is not visible in lawns yet. Conversely, tall fescue is a perennial and is obvious in lawns now because of it's coarse texture, usually lighter green color, earlier green-up than many other species, and accelerated spring growth. Digging it out or spraying with glyphosate or gluphosinate are the only ways to control tall fescue. On the other hand, applying a preemergence herbicide by early to mid-April can prevent crabgrass.

Let me know what you think.
Tall Fescue doesn't usually sport narrow leaves that clasp a stem so high as seen in the upper left corner of the bottom image.
Need to see auricles, ligule sheath, etc. Does the camera have a "macro" setting?
I could be wrong in my ID. However I did bring the plant back to the office and break out my ID guides and hand lens.
The photos Ant posted and the timing match my situation, additionally he is located fairly close.
I'm still curious what everyone else ID's this as.
you must have different tall fescue in your area. Tall fescue is grown here for grass seed, although it is considered a noxious weed in turf. There is an ornamental tall fescue know as dwarf tall fescue. Again, that does not look like tall fescue as the blades look thin.
Looks like chickweed
most Tall fescue doesnt grow in clumps like that. KY 31 does. you can fix your problem with a product called CORSAIR made by Riverdale. Active ingredient is Chorsulfuron. It also traets for rye grass. try it and you will be well pleased. nathan
The weeds besides the clump are chickweed. I have had the same problem with the clumps here in NC and its been here well over a month before crabgrass would show up.
I don't know what it is and my licensed sprayer says that he is seeing it everywhere and its not crabgrass????
i say fescue also..
