  6. The Future of Operational NWP??

  7. Meso-scale NWP • The prediction of the general characteristics associated with mesoscale weather phenomena WSR-88D CREF (02 UTC 30 Nov 1999) 6-hour ARPS Forecast at 9 km resolution

  8. Storm-scale NWP • The prediction of explicit updraft/downdrafts and related features (e.g., gust fronts, meso-cyclones) NEXRAD Radar Observations ARPS 90 min Forecast (3 km)

  9. What Resolution is Requiredfor Hydrologic Applications? 375 m Grid Downscaled to 375 m

  10. Downscaling?

  11. Spatial Accuracy is Key -- Ensembles 3 km ARPS Forecast Valid 00Z Monday, 16 June 1997 Amarillo Fort Worth
