Tonight, NBC takes a page out of its 1993 playbook, airing “Saturday Night Main Event” (7 p.m., NBC). This marks the first time in 13 years that the WWE event has aired on the network. But don’t go looking for Hulk Hogan. Tonight’s showcase features John Cena, Triple H, Trish Stratus, Shawn Michaels, Edge, Diva and Candice Michelle, and WWE honcho Mr. McMahon.

¢ Could one storm flummox the entire American economy? “We Were Warned: Tomorrow’s Oil Crisis,” a segment on “CNN Presents” (7 p.m. today, CNN), ponders what might happen if a category 5 hurricane struck Houston, followed by opportunistic terrorist attacks on oil production plants. Some experts think that gas could rise to as much as $8 per gallon, with predictable effects on the cost of living.

¢ A major Texas city also takes a beating in “Perfect Disaster” (8 p.m. Sunday, Discovery), the first of a six-part series exploring weather at its most violent and destructive.

In the first “Perfect Disaster,” conditions ripen for a supertornado to strike Dallas during the middle of afternoon rush hour on a summer day. This smartly produced and compelling series combines a dramatic story – that of an emergency worker and his wife and son caught in the storm – with a documentary-style look at the natural forces behind tornadoes, violent thunderstorms and hailstorms.

The next “Disaster” (9 p.m.) looks at the possible effects of cyclical solar flare-ups that could cause a global electrical failure.

¢ The nail-biting continues with “Time Bomb” (8 p.m. Sunday, CBS), a made-for-TV thriller starring David Arquette as a federal agent leading a squad out to defuse bombs designed to blow up a stadium during an NFL game. Oscar nominee Angela Bassett co-stars as the head of Homeland Security.
