OTHER AMENDMENTS TO THE ORIGINAL TIN INCLUDE: FULL CONUS GUIDANCE COVERAGE /THE INITIAL EXPERIMENTAL GRIDDED MOS HAD ONLY THE WESTERN THIRD OF THE NDFD GRID POPULATED WITH GUIDANCE/.
GRIDDED PRODUCTS FOR THE 24-HOUR SNOWFALL AMOUNT WILL BECOME AVAILABLE AT A LATER DATE.
UNTIL THE AUGUST 15 2006 IMPLEMENTATION... EXPERIMENTAL GRIB2 PRODUCTS FOR SOME ELEMENTS ARE AVAILABLE ON THE NWS FTP SERVER AT /USE LOWER CASE LETTERS EXCEPT FOR SL...ST...DF...DC...GT ...AND AR/:

ATTENTION USERS OF THE MODEL OUTPUT STATISTICS /MOS/ GUIDANCE:
THE NWS WILL PRODUCE NEW GLOBAL FORECAST SYSTEM /GFS/ -BASED GRIDDED MOS GUIDANCE AND DISSEMINATE IT ON THE SATELLITE BROADCAST NETWORK /SBN/... NOAAPORT... AND THE NWS FTP SERVER. THESE GUIDANCE PRODUCTS WILL BE IN GRIB2 FORMAT. THE NEW COMMUNICATION IDENTIFIERS FOR THESE PRODUCTS ARE SHOWN IN TABLE 1 BELOW. THE GRIDDED MOS PRODUCTS WILL CONTAIN GUIDANCE ON THE 5 KM NATIONAL DIGITAL FORECAST DATABASE /NDFD/ CONUS GRID FOR SELECTED ELEMENTS AT PROJECTIONS OF 1 TO 7 DAYS IN ADVANCE. GRIDS WILL BE GENERATED FROM THE 0000 AND 1200 UNIVERSAL COORDINATED TIME /UTC/ MODEL RUNS. GUIDANCE WILL BE AVAILABLE FOR THE FOLLOWING ELEMENTS WITH OTHERS TO BE ADDED AT A LATER DATE: 

 DAYTIME MAXIMUM AND NIGHTTIME MINIMUM TEMPERATURE
 2-METER SPOT TEMPERATURE
 2-METER SPOT DEWPOINT TEMPERATURE
 RELATIVE HUMIDITY
 WIND SPEED
 WIND DIRECTION
 PROBABILITY OF PRECIPITATION /6 AND 12 HOUR/
 PROBABILITY OF THUNDERSTORMS /3...6 AND 12 HOUR/
A WEB PAGE PROVIDING MORE INFORMATION REGARDING PROJECTIONS AND ELEMENTS FOR WHICH GUIDANCE IS AVAILABLE IS REFERENCED BELOW. TABLE 1: COMMUNICATION IDENTIFIERS FOR THE GFS-BASED GRIDDED MOS GRIB2 PRODUCTS. EACH GRIB2 PRODUCT HAS A UNIQUE WMO HEADER. LISTED BELOW ARE REPRESENTATIONS OF THE WMO HEADERS.
