General Information

What is the NDFD?

As the foundation of the NWS Digital Services Program, the National Digital Forecast Database (NDFD) consists of gridded forecasts of sensible weather elements (e.g., cloud cover, maximum temperature). NDFD contains a seamless mosaic of digital forecasts from NWS field offices working in collaboration with the National Centers for Environmental Prediction (NCEP). The database is available for members of the public to use in creating text, graphic, gridded and image products of their own. Over time, NWS will offer a wider array of gridded forecast elements and a larger set of graphical presentations. Access to the data and a description of NDFD elements can be found here. The policy directive which establishes the framework for weather, water, and climate services provided via digital forecast and guidance databases is available for more detailed information.

The Operations Concept for the NWS Digital Services describes the transition the NWS is making as we implement the NDFD and presents our strategies for provision of digital services to meet the evolving needs of our customers and partners.

Find out more about how and why the NDFD was created, the weather elements in NDFD, verification and future plans. See the navigation bar on the left for more links.

Images of grids for most NDFD elements are available online.
