as someone who is phobic of thunder and lightning im worried?

Yes there are a few weather options, 2 are for winter and 2 are for summer.
You can have the blizzard and the snow, or just the snow, and you can have both the thunderstorm and the rain, or just the rain.
There will also be one other option that will allow you to completely turn it all off. I'm so glad they did that, because this way if someone's computer can't quite handle it, all they have to do is turn it off. I had to do that for Sims 3, because weather and pets really took a bad toll on my computer.
