Somebody explain to me how this pattern forms in Bermuda grass in the Fall after the first cool spell.

Thanks to Holly Dickman, Ellis County Horticulture Agent, for sending in the lawn photos. Holly came across some bermudagrass with these very funky stripes. What causes this? This is caused by frost damage. Why the squiggles? I can’t find it now, but several years ago I stumbled across an article by some physicists where they modeled heat fluxes/temperature and came up with a model to describe how and why this happens. It was full of big scary equations I did not understand. Will there be lasting damage? No – this is a temporary condition, and the lawn will even out and go uniformly dormant as cool fall temperatures become more consistent.

K State is good for something.

Much better photo. All the lawns in my neighborhood look like this. We had a cool night last week, in the 40's, but frost never crossed my mind. This is common; see it every year. It's so prominent this year, I thought I'd put it to rest. Thanks. Thanks to K-State, too.
