I'm thinking it may be a metaphor to say something (maybe a person's heart) should be far more accommodating to any problems that come its way. A bit like describing the sky has room for any kind of weather, good or bad, but will always remain clear and blue once you take the clouds out of the equation. (Maybe I'm looking at it from a positive point of view! Haven't seen that used before, so I am just winging it here.)

Hi! Well, I don't know the context but my guess is that this is a sarcastic statement because bad weather conditions haven't changed for a long time and now the speaker is complaining about it in a rather witty way, using "like". Here are some examples: 1. A:I really like learning Russian! B: yeah, like a moron like you could learn Russian! 2. I need to borrow 5 thousand dollars. Yeah, like I'm gonna lend you that amount of money! In both these examples you can see "like" being used to express that the possibility of something happening is low (in a witty/sarcastic way)
