God controls the weather – Job 37:3-13

He directeth it under the whole heaven, and his lightning unto the ends of the earth. After it a voice roareth: he thundereth with the voice of his excellency; and he will not stay them when his voice is heard. God thundereth marvellously with his voice; great things doeth he, which we cannot comprehend. For he saith to the snow, Be thou on the earth; likewise to the small rain, and to the great rain of his strength. He sealeth up the hand of every man; that all men may know his work. Then the beasts go into dens, and remain in their places. Out of the south cometh the whirlwind: and cold out of the north. By the breath of God frost is given: and the breadth of the waters is straitened. Also by watering he wearieth the thick cloud: he scattereth his bright cloud: And it is turned round about by his counsels: that they may do whatsoever he commandeth them upon the face of the world in the earth. He causeth it to come, whether for correction, or for his land, or for mercy.

God is in control of His creation and He determines what the weather will be like. He uses it to show His power, excellency, and discretion.
