Though exceptional water surpluses will diminish through March, widespread and intense conditions will persist from Wisconsin through southern Minnesota, Iowa, eastern Nebraska, eastern Kansas, central Oklahoma, and central and eastern Texas. Surpluses along the Eastern Seaboard will also persist but moderate, while conditions in the Ohio River Valley normalize. In the western US, mild deficits are forecast punctuated by pockets of more intense anomalies, deficits as well as surpluses.

Similar conditions are expected across the border in China’s Northeastern Plain. The US Southwest can expect much wetter than normal conditions.
The forecast through November indicates that water deficits will downgrade considerably overall leaving mild to moderate deficits, but deficits will be intense along the Arkansas River through Kansas and Colorado, western Colorado, northeastern Utah, along the Canadian River through Oklahoma and the Texas Panhandle, and in the US Northeast.

The forecast through September indicates that, while exceptional water deficits will diminish overall and in the Southwest and Southern Rockies in particular, moderate to severe deficits are expected in a wide path from Missouri to the Gulf. Deficits may be intense in Louisiana, along the Arkansas and Canadian Rivers, and the Pacific Northwest coast. In the Northeast, deficits will persist and spread further in Maine. Significant surpluses will persist in the Northern Rockies, and surpluses will emerge in much of Florida.
