 There's an unusually high risk of strong to severe thunderstorms tomorrow in the eastern edge of Montana, the western Dakotas, portions of northeastern Wyoming. The biggest threats overall will be areas of wind. We could see winds in excess of 70 or 80 miles per hour, and hail could be as large as 2 inches or even 2.5 inches in diameter. We're also looking at an increased tornado potential tomorrow as well,
