This handout provides information on the typical La Niña winter pattern; the La Niña outlook; potential winter and spring impacts; and comparisons of conditions during previous La Niña years for the Missouri River Basin region. Updated November 2022.

NOAA’s Regional Climate Services Program created these outlooks to inform the public about climate impacts within their respective regions. Each regional report contains easy-to-understand language, and anyone can access them through the Drought Portal.

Quarterly Climate Impacts and Outlook for the Western Region for June–August 2022. Dated September 2022.

Temperatures were above normal across the entire West with many long-term stations in the top five warmest summers on record. Most of the West saw near-normal or above-normal precipitation this summer.

Quarterly Climate Impacts and Outlook for the Missouri River Basin for June–August 2022. Dated September 2022.

Temperatures were above normal for the majority of the Missouri River Basin, with the greatest departures in the western parts of Kansas and Nebraska. Precipitation was above normal in Colorado and parts of Wyoming due to the Southwest Monsoon, while other isolated pockets of near-normal precipitation were present in the basin. Much of Kansas and Nebraska were well below normal, resulting in the intensification of drought conditions in those states.

Compared to one year ago, the area in drought in the western U.S. shrank from 89% to 73%, while the area in Exceptional Drought (D4) dropped from 25% to 7%. Spring storms in the Pacific Northwest and Northern Rockies removed drought in parts of those regions. A robust summer monsoon has improved drought in parts of the Southwest, especially western New Mexico. The Southwest, California, and even parts of the Northwest have been stuck in a 20+ year megadrought, influenced by climate change.

Quarterly Climate Impacts and Outlook for the Missouri River Basin for March–May 2022. Dated June 2022.

Temperatures were below normal for the majority of the Missouri River Basin. The greatest departures were in North Dakota and northwestern Wyoming. Precipitation was well above normal in North Dakota and near normal over the Rockies and eastern Kansas. Over southwestern South Dakota, western Kansas, and eastern Colorado, precipitation was well below normal this spring.

Quarterly Climate Impacts and Outlook for the Western Region for March–May 2022. Dated June 2022.

Temperatures were below average across the Pacific Northwest, northern California, and the northern Great Basin. Dry conditions persisted across the Southwest with record low spring precipitation in parts of Nevada, California, Utah, Arizona, and New Mexico.
