Republican National Convention - UPDATE: Isaac has really messed things up. Not much is happening in Tampa except for the storm, but if anything happens, it'll be on cable news (the major broadcast networks hadn't scheduled primetime coverage for tonight even before Isaac blew in). Today's cancelations will likely mean extended coverage Tuesday-Thursday.  Tonight's highlights include speeches from Ann Romney, South Carolina governor Nikki Haley and former Arkansas governor Mike Huckabee.  Here's more information about RNC viewing.

Michelle organizes a fundraiser and advises the girls on their boy drama, but her friendship with Fanny goes off track when some mistakes are made. Foster recently told Entertainment Weekly that the episode ends in a cliffhanger, which means it's extra great news that ABC Family just extended the season. I guess that makes tonight's show a mid-season finale instead of a season finale. Either way, more "Bunheads" so hooray!

Superheroes (9pm, HBO) - You'll find plenty of comic book heroes on the movie screen this summer, but you won't see any like these. This award-winning documentary is about some everyday folks who dedicate their lives to being "real life superheroes" -- complete with superhero names, costumes, backstories, the whole deal. At first glance, many of these people may seem downright nuts, but as the film goes on, director Michael Barnett shows there's more to this lifestyle than a bunch of nerds running around playing dress-up. There's a lot of heart and soul in this film. It respectfully shows the true dedication of the superheroes, who in many cases are more effective at fighting apathy and helping the downtrodden than fighting actual crime. There are so many compelling characters in Barnett's film, but I promise you will never forget Mr. Xtreme or Master Legend (whose super power appears to be his raging thirst). Or Zimmer, who has the very useful power of being a trained EMT. "Superheroes" screened at San Diego Comic-Con this year. If you have HBO, check it out.

Alphas (10pm, Syfy) - In the pilot of this new series following a team of people with extraordinary abilities who investigate crimes linked to others like them, ominous messages steer a man to a building's rooftop, where he executes an improbable shooting. Our review here. 

The easiest way to think of “Alphas” (Syfy, 10 tonight) is like a poor-man’s “X-Men” mixed with a dash of  ABC’s cancelled “No Ordinary Family.”  Sadly, “Alphas” doesn’t have the engaging start “No Ordinary Family” did; you’ll probably lose interest with this first episode.

The “Alphas” opens with Cameron Hicks (Warren Christie), a good-looking guy who works in a supermarket. We learn later that he’s a former army sniper and phenom baseball pitcher. He suddenly starts getting messages to shoot someone, and when he does, it’s pretty clear he’s under the influence of someone or something.

Next we meet Dr. Lee Rosen (David Strathairn), a neurologist and psychiatrist and the  Dr. Xavier; apparently we’re supposed to think he’s eccentric because of his affinity for herbal remedies and skimpy swim trunks.
