Simply Take a bowl full of water and if you have 2 people sit across
from each other... if it is just you then just put it in front of you.
Make sure you make your circle then chant over the bowl of water "Water
Nymphs strike the clouds so rain will fall freely to the ground" while
doing that visualize clouds bursting open and water falling down over
the area you wish for rain. this really works i did it with a friend
once.
