It all depends on the priest really. The Church sets the liturgical calendar and the Scriptures are read from the Old and New Testaments on a daily basis. Many passages cover hell; however, each priest crafts their homily.
Personally, I've attended Mass on numerous occasions where the priest went in painful detail about hell.
Check out Venerable Fulton Sheen for some great homilies. Better yet, check out a parish and ask the question directly to the priest especially if the Scrriptures for the day point directly to this subject.
