Sharknado 2: The Second One (9pm, Syfy) - The ultimate bad Syfy movie, “Sharknado,” gets its sequel tonight, with shark-infested storms hitting New York City. But don’t fear. As luck would have it, the heroes from the first movie just happen to be in NYC for a Sharknado Survival Guide book tour, so they’ll once again save the day. Can’t reveal if that save involves helicopters and dynamite. Ian Ziering and Tara Reid return, along with guests Robert Klein, Judd Hirsch, Robert Hayes, Vivica A. Fox, Judah Friedlander, Matt Lauer, Al Roker and Biz Markie.
