The Climate Prediction Center has developed a soil moisture tool for the next 2 weeks based on the National Weather Service Global Forecast System (GFS) model. Monthly and seasonal tools are based on the Constructed Analog on Soil Moisture (CAS). Note that both of these are only forecast tools. They may be used in making the official outlooks that go out to the public, but are not official forecasts in their own right.  The GFS bias corrected ensemble forecasts (daily precipitation and temperature at 00Z & 12Z) for Week 1 and Week 2 are used to drive the soil moisture model.
