The forecast through December indicates many areas of water surplus including Iowa and surrounding states, the Ohio River Basin, eastern Pennsylvania, and Texas. Surpluses will be intense in Iowa and Pennsylvania. Deficits are expected in the Southeast, primarily moderate but more intense in Florida surrounding Lake Okeechobee. Intense deficits are also forecast along the Arkansas River, and in Colorado, and north-central Utah. Other areas of deficits include the Canadian River, the Rio Grande through New Mexico, and Maine.
The near-term forecast through September shows a distribution pattern of water anomalies similar to the prior three months with some decrease in intensity. However, surpluses are forecast to increase in the central Gulf Coast. Beyond September water anomalies will continue to become less severe, though pockets of exceptional surplus will persist in Idaho and its neighbors. The forecast through March 2018 indicates the emergence of primarily moderate surpluses in many parts of the country.
Exceptional water surplus conditions spanning the Pacific northwestern states of Washington, Oregon and Idaho are expected to moderate in the near-term. Moderate surpluses are expected to develop along the central Gulf Coast and extend up the Mississippi Basin through the forecast period, settling over the northern Great Plains states by early 2018. Severe to exceptional deficits are forecast to develop over most of Alaska and moderate but persist throughout the forecast period.
The outlook for the United States through December indicates that water deficits will continue to dominate much of the northeastern US, though the expanse of exceptional deficits is expected to shrink. Significant deficits will also persist from Ohio through the South, in Southern California, and along the Missouri and Yellowstone Rivers. A large block of surpluses will persist in Wisconsin, Minnesota and Iowa. After December deficits across the country will diminish considerably but surpluses in the upper Midwest are expected to persist and moderate surpluses will emerge in the Rocky Mountain States.
The forecast for the United States through November includes widespread extreme water deficits throughout the East and on the Missouri and Yellowstone Rivers, with moderate deficits in the West. A large pocket of surpluses is forecast along the Upper Mississippi River, encompassing southern Minnesota, much of Wisconsin, eastern Iowa, and northern Illinois. From December through February deficits across the US are forecast to diminish; surpluses will persist in Minnesota and Wisconsin and will continue to emerge southward.
United States: Water deficits to emerge this Spring in Ohio and lower Mississippi Valleys first, then Montana, North Dakota, Minnesota, Wisconsin, and throughout the Northeast.
Widespread moderate to extreme deficits are forecast for Montana, Wyoming, North Dakota, Minnesota, Michigan, much of the Mississippi Valley, and New England. Surpluses are forecast for the Southern Plains, east Texas, and southern Florida. Both deficits and surpluses are expected in in the Pacific Northwest, and parts of the Southeast.
Water deficits may dominate the northern US from the Pacific Northwest eastward through Minnesota in the coming months, with surpluses in the Upper Mississippi. The forecast for California indicates a transition from deficits to surpluses by February. Surpluses may persist in the Central and Southern Plains and along Mississippi River tributaries. Extensive deficits are forecast March through May from the central Gulf Coast region northward through the Great Lakes region.
