You should go anyways! What, you think when the Space Zombies show up it's always going to be bright and sunny with no wind??
Go. Learn to shoot with a heavy side wind or even in a good rain downpour if you have covered shooting.
We do that here as a practice. The PNW gets a ton of rain, adn every year we do a rain shoot, just to see the effects on your match grade target rifle with custom ammo versus the effects of mothernature. Long story short, she still wins.
You should go if it's not gail force conditions. It good for you to see how the bullets react to obstacles in their flight path...
