The front line of the cold front, where it meets the warm front, becomes warmer inch by inch, and water droplets condense, hiding in the clouds, waiting for the opportunity to fall.
Cold fronts and warm fronts merge, and no matter who has the upper hand, they always have to be compatible in the end.
Then there are rains that fall one after another, maybe not much, just as a proof of compatibility, falling on the dry land and giving birth to a gentle oasis.
