Hello, The new scheduled date for RAP implementation is now either 1 May or 8 May 2012. It was found that due to a script problem in the NCO version, the RAP had not been assimilating radar reflectivity data in 2012. Two other smaller issues were found also due to script issues: lack of GOES cloud-top data over full RAP domain, and issuing of 0h/analysis fields after the RAP digital filter initialization instead of before. The NCEP Centers will re-evaluate the RAP guidance now including these revisions for the next 30 days. Again, the planned implementation date is now set for 1 May or 8 May (both Tuesdays).
