I think now may be a little early. Winter sowing needs to be done when temperatures are consistently cold, and, who knows, things could warm up briefly again for us here before winter officially sets in. My recommendation would be to read the FAQs and maybe some of the threads in the Winter Sowing forum. There is a TON of info there. I think the FAQ section of that forum even lists which species to best with this method (if I remember correctly). Definitely worth checking out!

Here is a link that might be useful: Winter Sowing

Most of the 'winter sowing' on that forum is done in containers. I tried some of that for the first time last year, and will be doing some more this year. This post is really more about open-sowing, I guess you'd call it. I'm looking for info about annuals that basically self-sow well here, versus ones whose seeds won't survive our winters.

Personally, I would sow them (container or in-ground) the same way as far as timing goes (as described in the Winter Sowing Forum), but maybe someone will have other input.
