“BET Hip-Hop Awards” (8 p.m., BET): The second annual event honoring the best in hip-hop airs from Atlanta, hosted by comedian Katt Williams.

Common has five nods and Jay-Z got four. Ludacris and 50 Cent each received three nominations; Diddy and UGK have two each. Artist KRS-One, known for political and socially conscious raps, will be honored with the “I Am Hip Hop” Icon Award.

Criminal Minds” (9 p.m., CBS): On a new episode of “Criminal Minds,” Hotch and the team believe that a pair of suspects may be working together in a series of brutal home invasions taking place in Denver.

“Storm Chasers” (10 p.m., Discovery Channel): Each spring, across 700,000 square miles of mid-American flatlands, changing weather patterns and colliding air masses create a recipe for disaster. It’s also a rite of spring for scientists and storm chasers who flock in hopes of piercing a tornado. Discovery Channel transports viewers to “Tornado Alley” in the new series “Storm Chasers.” It joins research meteorologist Josh Wurman, who, from the turret of his self-designed Tornado Intercept Vehicle (TIV), drives straight into a deadly twister on a perilous sightseeing mission while team leader (and filmmaker) Sean Casey guides the TIV from his mobile command post.
