- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Dawson County: 0.
- Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

- A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

- The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

- Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
- Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

National Weather Service narrative
The National Weather Service in Glasgow conducted a damage survey in Glendive on July 28, 2015 following a significant severe thunderstorm that hit the evening before coming in from the southwest. NWS staff met with county and city officials before and after the survey to be briefed and brief them on what was discovered. The event was a macroburst (large scale straight line wind event) with some microburst components in between. | There were not enough time and resources to enter the various neighborhoods that were impacted, and due to the number of trees and power lines down, it was not safe to try and go around these areas where crews were working. In order to best evaluate the…
- Jun 14, 2006Thunderstorm Wind$2.0 million
National Weather Service narrative
A line of severe thunderstorms roared through the Glendive area and caused extensive damage. A National Weather Service storm survey was conducted, and it was determined that although there may have been funnel clouds in the area, all of the damage was caused by straight line winds of around 100 mph. The team first surveyed the damage just north of downtown, along the east bank of the Yellowstone River. Two trees, the largest of which was a 44 year old pine, were uprooted at a residence. Both trees were pushed leaning northeast onto and partially through the exterior wall and roof of the house. Throughout this area of the city, there were numerous other trees and branches taken…
- Jul 2, 2003Thunderstorm Wind$380,000
National Weather Service narrative
A semi truck over turned on I-94 approximately 10 miles southwest of Glendive. There was one injury reported with broken bones. Widespread wind and hail damage was reported in southern Dawson County. A tree fell through a house and caused approximately 100 thousand dollars of damage. Three grain bins were destroyed causing approximately 180 thousand dollars of damage. There was approximately 120 thousand dollars of damage to beet crops. Estimated total damage from the storm was 500 thousand dollars.
- Aug 11, 2000Thunderstorm Wind$250,000
National Weather Service narrative
A severe thunderstorm brought damaging winds and hail to central portions of Dawson County. The areas hardest hit extended from Lindsay to Bloomfield. In many areas crops were a total loss. Several barns were blown down damaging equipment and machinery.
- Jul 7, 2004Thunderstorm Wind$200,000
National Weather Service narrative
The area from about 10 miles southeast of Richey to 2 miles southeast of Bloomfield had approximately 12,000 acres of crop damage and high winds that caused some grain hoppers to be blown over. A grain hopper near county road 515 was completely toppled over and rolled about 150 to 200 yards downstream. Two miles southeast of Bloomfield, there were 5 grain hoppers that weigh 5,500 pound each, and two of the hoppers were toppled over. The crop damage was due to hail reported up to 1.5 inches in diameter with winds in the 40 to 60 mph range that lasted for 30 to 45 minutes.
- Jun 28, 2005Flash Flood$112,000
National Weather Service narrative
Thunderstorms which produced up to 4 inches of rainfall caused the water in the Glendive Creek approximately 6 miles east of Glendive to go from 6 inches deep and 6 feet wide to approximately 12 feet deep and nearly 100 feet wide. The water crossed old Highway 10. About 6 miles northeast of Glendive a bridge on Belle Prairie Road was washed out as well as a culvert on Road 311.
- Jul 20, 2001Thunderstorm Wind$75,000
National Weather Service narrative
The damaging downburst winds that occurred in McCone County continued into Dawson County. Several farms along Highway 200 had significant damage to outbuildings, and well as to equipment. Crops were 100 percent destroyed in a 1 to 5 mile wide swath from 12 miles northwest of Lindsay to the town of Lindsay. A home in Linsday also had the roof blown off.
- May 20, 2007Hail$62,000
National Weather Service narrative
Hail ranged from quarter size to two inches. Southwest side of home received window and vinyl siding damage. Double paned windows shattered on living room floor. Trees on property shredded from hail.
- Mar 10, 2014Flood$50,000
National Weather Service narrative
Ice moved into the Glendive area overnight on March 9-10. The ice jammed in Glendive causing the water to rise over 8 feet in less than 15 minutes. The jam caused water and ice to flow across the Marsh Road just southwest of town, and it also took out several power poles. The ice jam further impacted the town as water and ice filled into the Toepke Park baseball/softball complex. At least one 1,000 gallon propane tank was lifted from its base and floated down river. The USGS gauge in Glendive peaked at 57.29 feet, but the ice caused a large area of low-land flooding downstream of the gauge for the next 36 hours.

National Weather Service narrative
An early season winter storm affected a portion of northeast Montana from late in the afternoon of October 4th through early afternoon on the 5th. An area of low pressure tracked from Colorado on the morning of the 4th to the eastern Dakotas by the morning of the 5th. The storm produced between 6 and 18 inches of heavy wet snow. The heavy snowfall covered an area from extreme eastern Sheridan County and eastern Roosevelt County through eastern McCone, southeast Garfield, and Southern Petroleum Counties and points east to the north Dakota Border. The heaviest snow fell in Wibaux and Dawson Counties where more than a foot of snow was observed. The snow occurred at a time when the…
