A storm cloud appears in the shape of a cylinder that is 10 feet tall with a 120-foot radius, centered on a point you can see within range directly above you. The spell fails if you can’t see a point in the air where the storm cloud could appear (for example, if you are in a room that can’t accommodate the cloud).
When you cast the spell, choose a point you can see under the cloud. A bolt of lightning flashes down from the cloud to that point. Each creature within 10 feet of that point must make a Dexterity saving throw. A creature takes 9d4 lightning or thunder damage (your choice) on a failed save, or half as much damage on a successful one. On each of your turns until the spell ends, you can use your action to call down lightning in this way again, targeting the same point or a different one.
If you are outdoors in stormy conditions when you cast this spell, the spell gives you control over the existing storm instead of creating a new one. Under such conditions, the spell’s damage increases by 5d4.
At Higher Levels. When you cast this spell using a spell slot of 4th or higher level, the damage increases by 3d4 for each slot level above 3rd.
