Hail. I'm sure that the answer you're looking for is hail. As the Updrafts force the water molecules up, they began to freeze, in which case they become heavy and start to fall, only to be carried up by another updraft, in which case it freezes again, while adding more water molecules. This process repeats until the hail is heavy enough to finally fall to the ground and escape the updrafts. So yes, the answer is hail, I hope this helped!
