SUBJECT:  AMENDED: ADDITION OF NEW GFS-BASED GRIDDED MOS
         GUIDANCE: EFFECTIVE DATE OF NOVEMBER 29 2005
         POSTPONED

REFER TO: TECHNICAL IMPLEMETATION NOTICE /TIN/ 05-56
  TRANSMITTED ON JULY 22 2005

AMENDED TO POSTPONE EFFECTIVE DATE FOR ADDING GFS-BASED GRIDDED
MOS GUIDANCE FROM NOVEMBER 29 2005 UNTIL FURTHER NOTICE DUE TO
TELECOMMUNICATIONS OPERATION CENTER MORATORIUM ON SYSTEM
CHANGES. A FOLLOW-UP TIN WILL BE ISSUED WHEN A NEW IMPLEMENTATION
DATE IS SET. NOTE THAT EXPERIMENTAL DATA FOR SOME PRODUCTS IS
CURRENTLY AVAILABLE ON THE NWS FTP SERVER AS DESCRIBED BELOW.

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/
 24-HOUR SNOWFALL AMOUNT

A WEB PAGE PROVIDING MORE INFORMATION REGARDING PROJECTIONS AND
ELEMENTS FOR WHICH GUIDANCE IS AVAILABLE IS REFERENCED BELOW.

INITIALLY ONLY THE WESTERN THIRD OF THE NDFD GRID WILL BE
POPULATED WITH GUIDANCE.  THE OTHER TWO-THIRDS OF THE GRID WILL
CONTAIN MISSING VALUES.  NWS WILL FILL IN THE REMAINDER OF THE
GRID AS THE GUIDANCE BECOMES AVAILABLE.

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/:
