What the reports say
Written by National Weather Service staff at the time of the event · public domain
This was the first of multiple rounds of hail to strike the Williston area the evening of June 10. With this round, hail up to the size of tennis balls fell over the Williston area. This caused damage to many roofs and vehicles, including damaging every police car in the city, and every vehicle parked in the Williams County facility lot. In addition, strong winds with this storm blew a roof off a truck and car wash.
Between 3.00 and 7.00 inches of rain fell over a large part of Williams, Divide, Burke, and Mountrail Counties overnight August 21st and 22nd. Water damage from the heavy rains was widespread. A section of Highway 1804 was completely washed out. The downpour swept a motor home off the highway near Lewis and Clark State Park. Fortunately, the occupants escaped injury.
Spotters indicated that the most intense part of the hail swath from this storm began around 20 miles west of Ray, just to the south of Blacktail Dam, and was around 1 mile wide as it extended to approximately 2 miles north of Ray. The hail was accompanied by damaging thunderstorm winds in excess of 60 mph, which broke out windows and resulted in 100 percent crop loss in the hardest hit areas. Quarter size hail was also reported in the town of Ray, and was also accompanied by strong thunderstorm winds. This was part of the same storm which resulted in damage to the west and north of Ray.
