Yea they gobble before , during & after the strom.
They shock gobble at the crack of thunder & they will be out in the open field than under the cover of trees & brush.
Make sure you have some type silent rain wear & set up on the edge of a field , call at your desgertion.
Good luck
The one my son shot gobbled at least 80 times while he strutted at around 40 yards. He and two others gobbled several times before that. So to answer your question, Yes they do gobble in the rain. But probably not as frequently or reliably as when it's not.
Good Luck!
