The 13km RUC operational implementation at NCEP is now scheduled for 28 June 2005. The main differences from the current 20km RUC are improved surface forecasts, precipitation/cloud forecasts, and use of new observation types in the RUC analysis. It is currently undergoing an evaluation by NWS and NCEP Centers. Extensive documentation on the RUC13, including significant differences from the RUC20, has just been updated at http://ruc.fsl.noaa.gov/ruc13_docs/RUC13.summary.htm and http://ruc.fsl.noaa.gov/ruc13_docs/RUC13ppt.htm.
Intercomparisons between oper RUC20 and para RUC13 can be viewed through http://www.emc.ncep.noaa.gov/mmb/ruc2/para (developed by Geoff Manikin at NCEP/EMC).
