The forecast through December indicates that water deficits will shrink in the West and Southwest, downgrading considerably, but will remain intense in the Northeast and in Florida, and will emerge in the central Plains.
United States: Water surpluses to persist WI to TX, emerge in CA
Most notable in the forecast through April is the absence of widespread, intense water surpluses observed in the East in prior months. Surpluses will, however, persist in a massive path down the center of the country from Wisconsin through Texas, and moderate surpluses will emerge in the Rocky Mountains, in California from San Francisco Bay to the southern border, and along the Missouri and Colorado Rivers. Surpluses will be exceptional in central Kansas, on the Arkansas River, and in central Texas.

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.
