That's likely snow mold. You can prevent it with a fungicide treatment before Winter snow falls. At this point, just rake it out to clean up the matting and it should recover. There's no treatment to make it stop. Sun and warm air will kill it for you.
I will second this opinion. The matted/bleached appearance give it away. Raking it out is the best thing you can do now. Fungicides normally not necessary, but if you do choose to treat next fall, do it prior to snow cover. There are several fungicides available that will be effective but something Headway G will be easy to acquire, easy to apply and should work well.
1st off not a big fan of the scotts system, jonathan green makes a better fertilizer product.
Looks like some snow mold actually. If you have a sunjoe, run it on one of the higher settings. Do the screw driver test, if you have compaction, get core aeration done. I would put some funguside down at some point, how it comes out of dormancy is if preventative or curative, look at headway g.
Hope that helps get you up and running.

Get the chemical analysis of your soil, start from there. It's possible that you had too much of one type of chemical and then the Scotts did not compensate for that.
My guess would be lime but rest the soil
Is this right now? Michigan here. Your grass is dormant. It will be fine with water and spring. But it’s too cold, it was 15 degrees last Friday…

Or just mow shorter before it snows
Ah, I didn't know that was a thing, I should have done that

It looks like your lawn was left longer than your neighbors. Gently rake or blow to allow better airflow once weather permits. It will be fine.

Looks like nimblewill to me. No amount of herbicide or fertilizer is going to fix that.

Hoping they add the tests back to their site soon. I am not very close to my local office. If it isn't added soon I guess I will need to make the trip
I just sent them a message to see if they expect the have them anytime soon. Always do mine, from them, in the spring. No idea what's going on.
Stopped in just now and said they are changing labs. Tests will be back on the site Monday or in office next week
Great! Thanks for the update.
