I am someone who notoriously does not follow instructions well so I will chime in and share my experience. I'm in PA so similar climate.
I've planted plots early, late, and have taken shortcuts over the years here and there. My initial guess is that you have time to establish some clover and that it would likely be okay for next year but maybe not great. In my experience I always end up with mediocre results when my timing is off. You may get a winter kill because of a cold snap & shallow roots, you may end up with patchy clover and a bunch of weeds, etc. etc. I took the time on a bigger plot extension to plan appropriately, ensure I got a good kill with herbicide, and the results have been fantastic.
My suggestion is to wait until next year and just do it right. I've tons of time and money trying to fix plots that I planted in haste when if I just took my time and listened to time proven strategies I would have better results in less time & for less money.
That being said, if you have the time and money and want to give it a shot, go for it. But if things look shoddy next year, I'd just nuke it all and restart from scratch with appropriate timing & methods.
