Shimson & connection to thunder & lightning

I was at a funeral today for my son’s friend who died too young. In a eulogy, his grandfather said his Hebrew name Shimson meant thunder & lightning.

And then at the graveside, it was like the skies opened up – there was thunder and lightning and it poured. When I came home to Google this, I could not find a reference between Shimson & thunder/lightning, so I am sure I misheard something the grandfather said.

Can anyone help me piece together this connection?
