Below is just a portion of Psalm 104, which shows just a fraction of all the Lord is in charge of concerning the elements. If he can do all that then I'm sure that the rain can be stayed off for a little while yet. After all He was the one that caused the rain to cease for 3 years during Elijah's ministry to Israel (1 Kings 17:1-18:1). All I can say is that I'm going to keep the prayer going and I'll let you know what happens when the Lord decides to open up the heavens.
Psa 104:10 He sendeth the springs into the valleys, which run among the hills.
Psa 104:11 They give drink to every beast of the field: the wild asses quench their thirst.
Psa 104:12 By them shall the fowls of the heaven have their habitation, which sing among the branches.
Psa 104:13 He watereth the hills from his chambers: the earth is satisfied with the fruit of thy works.
Psa 104:14 He causeth the grass to grow for the cattle, and herb for the service of man: that he may bring forth food out of the earth;
Psa 104:15 And wine that maketh glad the heart of man, and oil to make his face to shine, and bread which strengtheneth man's heart.
Psa 104:16 The trees of the LORD are full of sap; the cedars of Lebanon, which he hath planted;
Psa 104:17 Where the birds make their nests: as for the stork, the fir trees are her house.
Psa 104:18 The high hills are a refuge for the wild goats; and the rocks for the conies.
Psa 104:19 He appointed the moon for seasons: the sun knoweth his going down.
Psa 104:20 Thou makest darkness, and it is night: wherein all the beasts of the forest do creep forth.
