"Your snowstorm"???????
I have a cousin who uses 'your' when someone with the same last name as some of our family and may/may not be connected, does something bad or could be considered less than desireable. Someone whose last name was the same as HER maiden name killed someone in California and when she mentioned it, she said "Did you see what YOUR cousin did?". Last time we spoke, I mentioned someone and she said "No, those are YOUR hillbilly cousins".
We didn't do it! It's not our fault. Nobody saw it. You can't prove it!
