Eureka: Season 2, Episode 3

2 - 3: Unpredictable

An isolated deep-freeze sets off a chain reaction of freak climate changes that soon escalate into a threat that could destroy Eureka and the rest of the planet. Also Carter's ex-wife gets in the mix when she arrives for Zoe's surprise 16th birthday party. Carter finds that the local weather is responsible. A scientist has created a way to control the weather, and the weather man would be out of a job, so he messed with one of the scientist's weather controlling devices and froze a lake, which lead to all the weather problems. So Carter plans on heating the lake up again with the same machine, but a hurricane keeps on blowing him away from it. Eventually he is able to reach the machine and heats up the lake again. The weather returns to normal. At the end of the episode, Abby, Carter's ex, tells him she is going to take Zoe back to Los Angeles.
