A significant set of changes was made to the HRRR and RAP experimental versions run in real-time at ESRL on 1 Jan 2015. A graphic summary of these changes is available at http://ruc.noaa.gov/pdf/HRRRv2-RAPv3-2015.png. A more complete summary of them is available in this presentation given at the Dec 2014 NCEP Model Review meeting - http://ruc.noaa.gov/pdf/NCEP_PSR_2014_HRRR_COMBINED_lite.pdf These changes to HRRR (HRRRv2) and RAP (RAPv3) are planned for implementation at NCEP this summer. More information on the NCEP implementations will be made available in the future as they are firmed up. Real-time experimental products from them are available at the ESRL HRRR and RAP websites now.
