Spring Outlook: Drought to persist, expand in U.S. West and High Plains

Nearly one-half of the country—stretching from the Pacific Coast to the Great Plains and upper Midwest—is currently experiencing moderate to exceptional drought conditions, and that is expected to continue and expand according to NOAA’s U.S. Spring Outlook released today. 

Drier conditions in the Southwest U.S. associated with La Niña and the failed 2020 summer monsoon have been contributing factors to the development and intensification of what represents the most significant U.S. spring drought since 2013, which will impact approximately 74 million people.

Temperature forecast through June

Map of temperature forecast for spring 2021 (April-June)

Places in the U.S. where the spring (April-June) temperatures are favored to be much warmer than the 1981-2010 average (reds) or much cooler than average (blues). White areas mean the chances for above-average, near-average, or below average are all equal. The darker the color, the stronger the chance of that outcome (not the bigger the departure from average). NOAA Climate.gov map, based on forecast data from NOAA CPC.

Precipitation forecast through June

U.S. precipitation outlook for spring 2021 (April-June)

U.S. precipitation outlook for spring 2021 (April-June). Places where the forecast favors a much wetter than average spring are colored green, and places where the forecast favors a much drier than average spring are brown. Much wetter or much drier means "in the upper or lower third of the recent climate record (1981-2010)." The darker the color, the stronger the chance of that outcome (not the bigger the departure from average). White means the chances of a wet spring, dry spring, or near-average spring are all equal. NOAA Climate.gov map, based on forecast data from NOAA CPC.
