I did my second jump last weekend. It started raining on the way up and we all agreed to go anyway. I wasn't wearing a suit, just a short sleeve and shorts. I had hundreds of small welts on my arms and legs that lasted until yesterday. It was not a pleasant experience. I can vouch for this jeromy. I did my second jump last weekend.

However, objects of different sizes, shapes, weights, and densities all are affected by air resistance differently. An object will continue to accelerate at the gravitational constant (9.8m per s^2) until the the gravitation force approaches and meets the air resistance force. This speed would be known as the terminal velocity. The terminal velocity of an average human being in freefall in our atmosphere is (for "flat" belly-to-earth flying) between 110-130 mph. However, due the different shape/weight of a rain drop, their terminal velocity is much lower - approximately 15 mph (I've been told - I have no reference for that quoted speed. I can tell you though, with quite certainly, if you skydive with the rain - it hurts! You are going faster than that rain drops and you will collide with them. Maybe not as much as being shot with a bb gun.. but close!

When you jump from a plane you have horizontal speed and zero vertical speed. According to physics, you would drop 10m/s just as rain drops would fall at the same speed. In the end you would be freefalling with the rain as if the rain was standing still, but then air friction comes into play and because our bodies have much larger surface area we would be slower than the rain but still a cool effect.
