The Weather God is the god that controls all the weather in the warm. He has a nasty temper and will send the worst weather possible at you if you even slightly annoy him. He doesn't specify how you annoy him though.
He gets pissed off at people living in rural areas the most meaning chat regulars like Bern has to deal with his wrath of bad weather, messing with peoples days.
it's safe to say the Weather God is annoying and is easy to anger.
