Avalanche

When you use this spell, you crush the snow in your hand choose a free space within the spell range and it creates a 25 square foot cube of magical snow. If a creature is under the snow when you create it, the creature must make a Strength or Dexterity saving throw and take 12d6 cold damage on a failed save and half as much on a successful one. After the spell duration, the snow melts and becomes non-magical water.
