You should be ok. Flights look good. MDW should be on 31c, and wx looks both in MDW and IND. If it's a -700, don't ever worry. The only time you should look, is if it's a -300 or -500 and they are on 22l or 4r. The mdw-orf flight is notorious for being structurally limited. PM me if you have any other problems. Good luck.
