The X Factor, 8 p.m., Fox

Modern Family, 9 p.m., ABC
“Cameron watches Alex and Luke while Phil, Claire and Mitchell deal with Haley's arrest; Jay tries to cut a surprise visit from Dede short, so she doesn't learn about Gloria's pregnancy.” I have to say, I’m a huge Shelley Long fan, but I don’t love DeDe.
Top Chef: Seattle, 10 p.m., Bravo
“Each judge puts the 21 new cheftestants through their own real-world challenge.” I am guessing this involves coffee and rain.
