Aha, then your answer to “if you don’t already know, then how do you learn?” is “you should just already know” / “use common sense”. Respectfully, that is quite unhelpful.

I was thinking a waterproof bag in case you set up and a storm rolls in and you have to pack up then get back to shelter. My common sense says be prepared because you don’t even want expensive gear to get wet while being transported.

Anyone doing astrophotography has already been watching the forecast for days in advance. There's not really going to be something rolling in they didn't anticipate, unless you're really planning for it.

Depending on where you are and the type of weather you have, a storm rolling through could be the best thing. I'm in Texas, and my favorite spot to go is a place 4.5 hours away. If you want to view things around the center of the Milky Way, you'll need to be viewing during the summer. Texas and summer don't make for friendly viewing conditions. However, if you catch one of those thunderstorms that blows through in half an hour or so, they can clear the air so that you have much better conditions after. You just gotta time it right!
