Hard to tell this far ahead, but right now it looks like it might; 40% probability, scattered thunderstorms.
Check
www.weather.com tomorrow afternoon (Augusta, GA, hourly forecast - it'll give you probabilities by the hour).
Rain may be uncomfortable (but it'll be warm)- its the wind I'd worry about. Depending on how your rocket is configured, there is a a little trick we found that may help. On ours, the capsule (a plastic cup, open side down) sits on a ring on a 1L bottle which is attached on top of the pressure vessel bottle. Ring is just below where the top of the bottle starts to slope inward (top is cut out for placement of part of a plastic cup which provides a chute compartment). When the wind is up, sitting ready to launch, the capsule cup can blow off. The cure is a little piece of Scotch tape, put on just below the ring (on the side the wind is blowing from); make the tape
just barely catch the lip of the cup, and immediately past where it catches the cup lip, put a piece (like a 1 inch square) of acetate plastic (like overhead slide material), or stiff paper would work. It should be sticking up at like a 10-15 degree to vertical. When you launch, both G-forces, and the the airstream moving by work to peel the tape away from where it touches the cup. Getting the amount of tape contact right is a little tricky; it doesn't take much to stabilize the cup prior to launch; too much contact and it won't peel away.
Good luck.
