A group here had storm static just like you and a 2-meter machine. It would start to build up, then discharge rather noticeably. This would repeat until the storm arrived. The antenna was a fiberglass collinear. Spoke with the local GE sales rep who had experience with this problem. His advice was to not use a fiberglass antenna and go to an antenna with each element at ground potential. That solved the problem we had.
I have to wonder if you don't have something adequately grounded or bonded or if the ground system is inadequate for the site.
