7/28/2012:
A large storm traveled through west-central North Dakota on this date in 1996, producing a tornado near Turtle Lake and causing extensive hail damage. The tornado was relatively small, only about three yards wide and extending over a twenty-mile path. An F1 on the Fujita scale, it caused $70,000 in damage, despite occurring in a relatively isolated rural area. The surrounding hail storm dropped one- to two-inch hailstones across several counties. The largest hailstone was reported a couple miles south of New Rockford, with a diameter of four and half inches! Amateur photographers captured the Turtle Lake tornado in a series of incredibly clear photographs from its earliest development to its final dissipation.
