NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. Other tornadoes recorded nearby that day are shown faint.

What F0 means. This tornado was rated on Fujita’s original scale, used until 2007. F0 meant light damage: shingles and siding peeled, gutters torn, branches broken; the scale paired it with winds of 40–72 mph, figures later judged too high, especially toward the top of the scale, and revised downward in the Enhanced Fujita scale. Ratings then, as now, came from the damage.

What the National Weather Service wrote

Brief tornado occurred south of Scobey.

The wider storm

A large supercell formed in Southwestern Phillips County and headed east across southern Valley County. The storm produced a tornado that crossed from Phillips County into Valley County. The tornado dissipated as the storm moved east, but golfball size hail was reported for 20 minutes at The Pines Recreation Area. The storm crossed over the east side of Ft. Peck Lake and formed another tornado near the Rock Creek Recreation area. The tornado then crossed Highway 24, in McCone County. Four inch diameter hail was reported with this storm at the time of the tornado. The tornado continued in a southeast path towards the town of Circle. The last known location of the tornado before it dissipated was 22 miles northwest of Circle. Downburst winds and golfball size hail then became the more significant threat from this storm. The hail and high winds caused a large area of 100 percent crop damage from 10 miles north and northwest of Circle to Lindsay. The damage swath was 1 to 5 miles wide. Other large hail and high wind reports were received from the Richey and Bloomfield areas in northwestern Dawson County as well. 25 large steel electrical towers were blown over in the area between Circle and Richey, and 25 wooden electrical poles were snapped also. The storm continued southeast toward Glendive and then followed Interstate 94 into North Dakota. No more substantial damage was reported once the storm passed through the Lindsay area. A few smaller tornados were reported by law enforcement officials northwest and north of the Glendive area, but they did not cause any damage and were short lived.

Began near Scobey (48.6833, -105.4167).
