I'd love this idea! I'm a huge meteorology nerd and extreme weather options would please me greatly. Make it appropriate to season and just destructive enough to keep things interesting while your sims get back on their feet. (Maybe introduce new death types from it, too.) But make it able to be disabled. It won't be everyone's cup of tea.
I'd also love a meteorologist career track that could get something similar to the weather machine or a reward that lets them predict when extreme weather is about to hit and take precautions.
