Through December, widespread water surpluses of varying intensity will persist in the Plains States and the Upper Midwest, forming a column from North Dakota through northern Oklahoma. Surpluses will be extreme to exceptional in the Dakotas. Primarily moderate deficits are forecast from the Ohio River Valley to the Atlantic and south to the Gulf, but anomalies will be intense in West Virginia and states to the east. Intense deficits are also forecast for central and southeastern Colorado.
United States: Widespread water surplus to persist in SD, NE, KS, OK
Widespread water surpluses observed in prior months will shrink through November. However, a broad column of surplus is forecast from southern North Dakota reaching into north-central Texas with intense anomalies in South Dakota. Other areas of surplus include eastern Nevada into western Utah, Wyoming, and California from San Francisco through the southwest. A pocket of exceptional deficit is expected in the central Everglades.
United States: Water surpluses will continue to dominate central states
Water surpluses are forecast to be the dominant anomaly in the U.S. through April 2020. Through October, significant surpluses are forecast from South Dakota into Texas and will be particularly widespread and intense in South Dakota. Surpluses are also expected in parts of the Rockies, pockets in the Southwest, nearly all of California, Michigan, pockets in the Ohio River Valley, and near Tampa Bay, Florida. Areas of deficit include the Pacific Northwest, northern Minnesota, and the Carolinas.
United States: Intense water surplus forecast from S. Dakota into Texas
Through September, water surpluses along the Mississippi River, its tributaries, and states on the western bank of the river will moderate, but significant surpluses are forecast in a column from South Dakota through central and eastern Texas and will include extreme to exceptional anomalies in many areas, particularly South Dakota. Areas of deficit include the Pacific Northwest, northwestern Minnesota, the western Upper Peninsula of Michigan, and along the Atlantic coast in North Carolina.
United States: Exceptional water surpluses forecast for S. Dakota
The forecast through August 2019 indicates persistent water surpluses in a wide path through the center of the country in the Mississippi River Basin and well into the Missouri, Arkansas, and Red River Basins, including exceptional anomalies in South Dakota. Surpluses of varying intensity are expected in the Rockies, central Arizona, California, Oregon, and in the Northeast. Deficits are forecast for pockets of Washington, North Dakota, Wisconsin, and southeastern states.
