A joint effort from USDA-ARS, Colorado State University, the National Drought Mitigation Center, University of Arizona, and the Northern Plains Climate Hub have come up with a forage prediction tool called ‘Grass-Cast’. It takes historic forage production data sets and climate predictions from NOAA to make forage forecasts. This is a useful drought planning tool. Right now the map shows much of western South Dakota is now in a better position than last year. However the east central and northern central part of South Dakota is going to suffer.
