You summon a massive storm cloud that hovers above an area you can see within 1 mile. The cloud covers a  100- foot-radius, centered on the point you chose, as long as it is within range. Each creature in the storm's radius must make a Dexterity saving throw. A creature takes 8d8 bludgeoning damage and 10d6 cold damage on a failed save, or half as much damage on a successful one.

The stormcloud causes snow to fall heavily, making the area heavily obscured and turns the storm's area of effect into difficult terrain until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the bludgeoning damage increases by 2d8 for each slot level above 4th.
