Extreme Summer Heat Amplifies Impacts of the Northern Plains Drought

  • Drought conditions continue to persist across the Missouri River Basin, most severely affecting North Dakota, South Dakota, Montana, and Wyoming. Excessively early summer heat is now an added concern on top of the dry conditions that have been an issue since the fall of 2020. Record-high temperatures dominated the Northern Plains from June 3-5, with 100+°F temperatures in areas of Montana, North Dakota, and South Dakota.
  • Drought impacts in the areas with extreme to exceptional drought are affecting many sectors through increased wildfire activity, decreased livestock forage and water availability, increased livestock heat-stress, reduced rural water supply and quality, reduced recreation and tourism, increased mental stress, decreased air quality, and ecological impacts due to reduced water levels. The recent extreme heat made drought impacts worse by increasing fire risk, inhibiting plant growth, and enabling harmful algae blooms.
  • In the short-term, extreme summer heat is expected to return from June 18-24, with the peak of the heat occurring on June 18-22 when temperatures could reach the upper 90s°F to low 100s°F. Beyond the upcoming extreme heat, NOAA’s summer outlook (June-August) for the Northern Plains is currently leaning towards above-normal temperatures and below-normal precipitation for much of the region throughout the rest of this summer.
  • The extreme summer heat will continue to worsen drought issues by further increasing fire risk, limiting water supply for livestock and societal uses, intensifying water quality issues, and continuing to cause stress on farmers, ranchers, recreationists, vulnerable or disadvantaged populations, and others affected by the drought.
