About the Short Range NDFD Graphics

The National Digital Forecast Database (NDFD) contains a mosaic of digital forecasts from the National Weather Service (NWS) field offices working in collaboration with NCEP. The forecasts depicted on the previous page — and in the example below — combine WPC forecasts of fronts, isobars and high/low pressure centers with the NDFD depiction of expected weather type.
