  1. National Weather ServiceForecast Evolution and Delivery in a Digital Era Glenn Austin / Mark Tew Office of Climate, Water, and Weather Services 2007 Annual AMS Conference San Antonio, Texas January 18, 2007 NOAA/NWS Digital Services

  2. National Digital Forecast Database • NDFD has been operational since 2004 • Domains include: • CONUS • OCONUS (AK, HI, Guam, PR/V.I.) • 16 sub-sectors • Information available electronically: • Electronic File Dissemination Services • XML Web Service • Web-based Graphics • GIS Compatible Formats • Online Archive Access System NOAA/NWS Digital Services

  3. Actions Completed in 2006 • Transitioned Apparent Temperature and RH grids to operational status (3/15/06) • Implemented experimental TPC Tropical Cyclone Wind Probability grids (7/5/06) • Implemented experimental Wind Gust grids (9/6/06) • Split NDFD Files (Days 1-3 and 4-7) (9/6/06) • Implemented six experimental grids for Alaska (9/6/06) • Implemented experimental QPF grids for Hawaii (11/1/06) • Conducted NDFD Technical Workshop (11/2/06) • Adjusted time NDFD is extended 24 hours to 22Z (11/28/06) • Transitioned XML Web Service to operational status (12/4/06) NOAA/NWS Digital Services

  4. Experimental elements: QPF Snow Amount Sky Cover Significant Wave Height Probability of Tropical Cyclone Wind Speeds Wind Gust Operational elements: Maximum Temperature Minimum Temperature Temperature Dew Point Probability of Precipitation Weather Wind Direction Wind Speed Apparent Temperature Relative Humidity NDFD Status(as of January 2007) NOAA/NWS Digital Services

  5. Activities Planned for FY07*(resources permitting) • Implement experimental SPC Convective Wx grids (Q2) • Implement experimental CPC Temp/Pcpn Outlook grids (Q3) • Implement experimental Max/Min RH grids (Q3) • Transition QPF grids to operational status (Q3) • Transition Snow Amount grids to operational status (Q3) • Transition Significant Wave Height grids to operational status (Q3) • Transition TPC Tropical Cyclone Wind Probability grids to operational status (Q3) • Transition Sky Cover grids to operational status (Q4) • Transition Wind Gust grids to operational status (Q4) • Transition Alaska grids to operational status (Q4) • Conduct 2007 Technical Workshop (FY08/Q1) * Domains for new forecast elements not specified NOAA/NWS Digital Services

  7. BackgroundSlides NOAA/NWS Digital Services

  8. Products Under Development Convective Weather Elements From SPC: • Probability of Tornadoes • Probability of Hail • Probability of Severe Storm Winds • Probability of Significant Tornadoes • Probability of Significant Hail • Probability Significant Severe Storm Winds • Total Probability of Severe Storms NOAA/NWS Digital Services

  9. Products Under Development Climate Outlooks from CPC: • Probability of 8-14 Day Temperature and Precipitation Above/Below Normal • Probability of 30 Day Temperature and Precipitation Above/Below Normal • Probability of 90 Day Temperature and Precipitation Above/Below Normal NOAA/NWS Digital Services

  10. NDFD Evolution: Focus on High Impact Services • Implement experimental WFO Hazardous Wx grids • Implement one-hour resolution forecast elements in NDFD • Increase grid-spacing resolution to 2.5 km nationwide • Implement experimental Fire Weather grids • Implement experimental Aviation grids NOAA/NWS Digital Services
