They are currently booking through January 9. The next time they add dates they will probably either stop short of the dates that cover President's day or go to some time in early March. It looks like you're planning to head down for President's day holiday which will be tough to get at a low fare. If the fare seems reasonable to you, book it. If they lower it you can rebook & get a credit if your dates/flight times are available at the lower rate. Keep checking the SWA website. If you haven't signed up for their e-mails do it now. This will remind you to check the website at least once a week. They don't really announce when they add new dates but the reservation page always tells you what date they are booking through. A good fare from MacArthur is $79 or less each way. I've booked my last 5 trips through them and ended up with $49 each way for all of them. Another tip, if they post dates that only go as far as your departure but not return you can always purchase 1-way to lock in a good price and buy the return when those dates become available. I had to do this for my Oct/Nov trip.
