That said, I have only ever seen one serious blizzard and one serious thunder storm. It was actually really cool. once I arrived to my destination, I was in the keep and I could hear the thunder outside at times, fairly loudly if I hung out near a window or outside door.
I just spent the last two game sessions (about 4 hours) in a real gloomy overcast with a pinch of showers. Just enough to make the weather miserable. I rested at an abandoned camp site and awoke to a beautiful dawn with clear skies and birds chirping. My spirits were actually lifted, it was pretty cool.
