The American Meteorological Society's Annual Partners Meeting on January 13, 2005, in San Diego, CA, highlighted critical updates from the National Weather Service's Digital Services team. Key discussions included the operational readiness of the NDFD grids and necessary improvements before declaring them official. Future plans aim to align grids for Hawaii, Guam, and Puerto Rico with CONUS standards. The meeting emphasized enhancing grid performance and quality assurance practices to reduce forecaster workload while maintaining accuracy in weather forecasts.

  3. Active December Weather

  4. Summary of NDFD Grid Readiness • Operational status on December 1, 2004: • Max Temperature • Min Temperature • PoP 12 • Transition to operational status on March 15, 2005: • Temperature • Dew Point • Weather • Improvements are necessary before declaring these grids official: • QPF • Snow amount • Sky cover • Wave heights • Wind direction • Wind speed • Users will be given a minimum of 30 days notice when an element moves from experimental to operational status. • NOTE: This evaluation is for CONUS only. We will be evaluating Hawaii, Guam, and Puerto Rico grids over the next three months.

  5. Criteria Utilized • Guidelines for recommended product transition • - Spatial Consistency • - Timeliness • - Completeness • Assessment of NDFD verification scores • (http://www.nws.noaa.gov/ndfd/verification/) • - Forecast error • - Forecast bias • Subjective look at grid quality • - Appearance • - Other issues

  6. Frequency of Downloads Ranking for CONUS Experimental Grid Elements • Wind Speed • PoP 12 Wave Heights • Temperature • Wind Direction • Min Temperature • Max Temperature • Snowfall • Dew Point • Sky Cover • QPF • Weather

  7. Program Status • Grids are improved over past 12 months • Expect improvement over rest of FY 2005 due to: • Sharing best practices from high performing WFOs • Mandating use of Quality Assurance smarttool • Investigating sources of inconsistencies and problems • Director level review of issues and problems – Monthly • Revised policy/definitions 10-506 – March ‘05 • AWIPS software improvements – June ‘05

  8. Issues • Goal: Reduce NWS Forecaster workload and maintain quality for Days 4-7 • NCEP/HPC grids on Satellite Broadcast Network - Now • NCEP/HPC grids onto AWIPS – Spring ’05 • Discussing updating only four times daily due to GFS/DEGEX guidance • Focus on maintaining currency in Day 1 grids

  9. Future Plans • Short Term • Bring Hawaii, Guam and Puerto Rico grids status in line with CONUS – Spring 2005 • Start Alaska region experimental grids – Summer 2005 • Add RH and apparent temperature (calculated grids) – Spring 2005 • Standardize web page presence and digital display issues – Summer 2005 • NOAA digital database portal plans – Summer 2005

  10. Future Plans • Long-Term • Move from deterministic to quantifying uncertainty • Increase spatial resolution to 2.5 km • Increase resolution to hourly • Add additional elements and extend domain vertically and horizontally
