For where you are, I think it's too late, by about a month, maybe two.

Save the weed killer for the spring.

I agree. Here in NJ I would say yes, but that far north it's
probably not going to be that effective or worth it. The amount of
herbicide and/or the number of applications required goes up as the
temps go down. Even Roundup takes a higher concentration and longer
to kill plants when they are barely growing due to lower temps.
