What does the rain say?

Calm sometimes stormy.
Let me introduce myself to my homies
I am an effect—scientifical
However, my soul is philosophical.
Evaporating heat out of heavy hearts.
Cooling the destination is my aim from the start.
Bugs and bunnies see me as a meeting sign
Making the greens lushy, Yes I do the refine.
Grey clouds hold me till the orders define.
Here I pour away.
Thank you, enjoy my time.
