A little slower tonight after yesterday’s craziness.

But only a little.

ABC premieres “FlashForward” at 8 p.m., but the biggest of the night has to be the two-hour premiere of “Grey’s Anatomy” at 9 p.m. After all the post-season cast drama and changes, it will be good to see how the show turns out this season.

CBS premieres a new season of the original “CSI” at 9 p.m. as well as “The Mentalist” at 10.

The Discovery Channel will go the route of SyFy and take on some ghostly ways with two Texas brothers searching for the ethereal in “Ghost Lab,” premiering October 6 at 10 p.m. In the 13-episode series, Brad and Barry Klinge travel the country in their mobile lab in search of ghosts.

Finally, this morning, The CW has ordered a mid-season docu-reality series called “Fly Girls” about a group of female flight attendants (we can’t say stewardesses anymore) working for the new Virgin America airline. The premise of the corporate-feeling show is to follow five hotties around their work and personal life as they share a home in Los Angeles and fly around the country.
