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!
