Abstract: 
 This datasets contains 40 maps representing relative humidity forcasts for times occuring every three hours during the next seven day period. The model is run every three hours, so these forecast projections are relative to real-time, plus or minus three hours. RELATIVE HUMIDITY is the expected Relative Humidity (RH) for the indicated hour. RH is derived from the associated Temperature and Dew Point grids for the indicated hour.
The National Digital Forecast Database (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 made available to all customers and partners from the public, private and academic sectors. Those customers and partners may use this data to create a wide range of 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.
Purpose: 
Many technological advances and scientific breakthroughs have allowed NWS weather forecasts and warnings to become much more specific and accurate. However, the production and dissemination of routine NWS forecasts must keep pace with the need for such information in this digital age. A primary means of providing sensible weather element forecasts (e.g., cloud cover, maximum temperature) from NWS Weather Forecast Offices (WFO) is still in text format. A new Interactive Forecast Preparation System (IFPS) is being implemented in NWS which provides not only for preparation of familiar text and voiced products, but also creates in digital (i.e., numerical) form the data from which these products are prepared. These digital forecasts are put into the NDFD. In essence, the forecaster now enters the forecast variables in digital form instead of redundantly typing several products containing largely the same information. But the real power of a digital database is that it opens the door for providing much more forecast information and in more useful forms. The NDFD will contain much more data than the NWS was previously able to provide, at time scales as small as hourly and space scales of a few kilometers.
