Both "Warehouse 13" and "Eureka" have spent years pulling in record numbers to Syfy on Summer Tuesday nights. Now they'll just have to do the same thing on Mondays.

The two popular shows move back a day when they premiere new seasons July 11, part of an overall summer schedule for Syfy that includes plenty of unscripted television as well.

"Eureka" returns for the back half of Season 4 at 8 p.m. as the town where geniuses thrive continues to recover from the major timeline changes caused by the trip back to 1947. However, an "accident of astronomical proportions" moves the town to one of its most ambitious projects yet, causing the town to rally around its scientists. But nothing is always bright, as some local secrets begin to emerge.

On "Warehouse 13," which begins its third season at 9 p.m., the agents are still reeling from the sudden departure of Myka (played by Joanne Kelly). Yet Artie (Saul Rubinek) wastes no time in bringing a new agent to the fold, Steve Jinks, played by none other than Aaron Ashmore of "Smallville" fame. And he has a talent that will keep you honest.

Making its series premiere right after "Warehouse 13" at 10 p.m. is "Alphas," a team of ordinary citizens with extraordinary mental and physical abilities. Sound a little like "Heroes" or "X-Men"? Maybe, but it's a bit of a cross between the two.

Like both, the Alphas are normal people trying to figure out new abilities. But like "X-Men," they work together as a team. And it's all done under the leadership of Zak Penn (writer of the upcoming "Avengers" movie directed by Joss Whedon) and Star Trek alum Ira Steven Behr.
