The near-term forecast through January indicates several striking changes from the prior three months: a transition in the Gulf Coast from water surplus to deficit, a broad path of deficits in the South Atlantic States, and surpluses from the Upper Midwest through the Ohio River Valley into the Northeast. In the spring normal water conditions should return to the Ohio River Valley and the Northeast, surpluses will continue to emerge in the Upper Mississippi, and deficits will moderate in the Lower Mississippi, Texas, and the South Atlantic States.
United States: Exceptional water deficits forecast AR, MO; surpluses in ID
Though the extent of exceptional deficits from Missouri to the Gulf and to the Atlantic is expected to recede from March through May, exceptional deficits will persist in Arkansas, Missouri, and western Illinois, and moderate deficits will emerge throughout much of the US east of the Mississippi. Surpluses are forecast for the Pacific Northwest, Idaho, northern Nevada, Central California, western Nevada, and western Colorado and are expected to be exceptional in Idaho, parts of Central California, and along the Columbia River.

United States: Water surpluses in Upper Midwest, Northwest, deficits in the South
The outlook for the United States through January indicates that water deficits will dominate the Ohio River Valley west through Arkansas and south to the Gulf, as well as the Delaware and lower Susquehanna drainages. Surpluses of varying severity are forecast for a vast block of the Northwest, Minnesota, Wisconsin, Iowa, and eastern North Carolina. From February through April the severity of both deficits and surpluses will diminish and some states in the Midwest and Northeast will transition to near-normal conditions. However, surpluses will persist in much of the Northwest and Upper Midwest.
