A blizzard forms, centred on a point you can see and spreading to a radius of 80 feet. The blizzard spreads around corners. The area becomes difficult terrain and is heavily obscured. Ranged weapon attacks in the area are impossible. The frigid winds count as a severe distraction for the purposes of maintaining concentration on spells. These winds (ranging from 20 to 50 miles per hour) automatically disperse fog, mists, and similar phenomena in the area whether mundane or magical.

When the blizzard appears, each creature within it must make a Constitution saving throw. A creature takes 11d8 cold damage on a failed save, or half as much damage on a successful one.

For each round thereafter, while you maintain concentration on this spell, a creature must make a Constitution saving throw when it enters the spell's area for the first time on a turn or ends its turn there. A creature takes 3d8 cold damage on a failed save, or half as much damage on a successful one.
