SUBJECT:  SOLICITING COMMENTS ON PROPOSED REPLACEMENT OF 
	  ETA-BASED MOS PRODUCTS WITH NAM MOS PRODUCTS THROUGH 
          AUGUST 20 2008

NWS IS PROPOSING TO TERMINATE PRODUCTION OF THE MODEL OUTPUT 
STATISTICS /MOS/ GUIDANCE FROM THE ETA MODEL. THIS PROPOSED 
CHANGE IS NECESSARY BECAUSE NWS REPLACED THE ETA MODEL WITH THE 
NON-HYDROSTATIC MESOSCALE MODEL /NMM/ VERSION OF THE WEATHER 
RESEARCH FORECAST /WRF/ MODEL IN JUNE 2006. USERS CAN FIND A 
PREVIOUS PROPOSAL TO TERMINATE ETA MOS GUIDANCE /USE LOWER CASE/: 
            
HTTP://WWW.WEATHER.GOV/MDL/SYNOP/WRFEVAL/ETAMOS_TERMINATION.PDF

FEEDBACK INDICATED THAT SUITABLE POST-PROCESSED GUIDANCE DERIVED 
FROM THE CURRENT NORTH AMERICAN MESOSCALE /NAM/ MODEL IS 
NECESSARY BEFORE TERMINATING THE ETA MOS. WRF-NMM MOS GUIDANCE IS 
NOW AVAILABLE AS A REPLACEMENT.

USERS CAN FIND A DETAILED EXPLANATION OF THIS PROPOSED 
REPLACEMENT AND DESCRIPTION OF ALTERNATIVE SOURCES OF STATISTICAL 
GUIDANCE AT /USE LOWER CASE LETTERS/:
