In the winter, there were a few times when a big snowstorm was coming, that I'd start to feel either sick, or wobbly, or more numb. Not sure if it was the stress of knowing a snowstorm was coming, or a real MS thing that was causing it.

I really do not like snow anymore.

I love thunderstorms, but yes, I have noticed that when a big storm (like severe t-storms or tornadoes) is brewing, I'll feel weird in the MS symptoms. Just depends on which symptom is feeling sensitive to the weather/barometric pressure change.
