THIS IS A REMINDER THAT THREE OF THE INITIAL 12 EXPERIMENTAL ELEMENTS FOR
THE CONTIGUOUS U.S. /CONUS/ IN THE NATIONAL DIGITAL FORECAST DATABASE
/NDFD/ WILL BE DECLARED OFFICIAL ON DECEMBER 1 2004 AT 1400 COORDINATED
UNIVERSAL TIME /UTC/. THE THREE OFFICIAL ELEMENTS FOR THE CONUS WILL BE:
MAXIMUM TEMPERATURE

AT 1400 UTC ON DECEMBER 1 2004...THESE ELEMENTS WILL BE MOVED FROM THE
CURRENT EXPERIMENTAL ELEMENT DIRECTORIES TO THE OFFICIAL ELEMENT
DIRECTORIES... FOR THE NATIONAL MOSAICKED CONUS GRID AS WELL AS THE
16 CONUS SUBSECTOR GRIDS...AS DESCRIBED BELOW AND IN TABLE 1.
THERE WILL BE NO OVERLAP OF DATA BETWEEN THE OFFICIAL DIRECTORIES AND THE
EXPERIMENTAL DIRECTORIES. ONCE AN ELEMENT BECOMES OFFICIAL AND MOVES TO
THE OFFICIAL GRID DIRECTORY...IT WILL NO LONGER BE ACCESSIBLE IN THE
EXPERIMENTAL DIRECTORY. SEE TABLE 1 FOR A LIST OF THE CURRENT AND NEW
DIRECTORIES TO ACCESS MAXIMUM TEMPERATURE...MINIMUM TEMPERATURE...AND
PROBABILITY OF PRECIPITATION /POP12/ FOR THE CONUS.
PARTNERS AND CUSTOMERS MUST UPDATE THEIR PROCEDURES AND SCRIPTS TO ENSURE
ACCESS TO THE THREE NEW OFFICIAL GRID ELEMENTS WHICH ARE BEING MOVED TO
THE OFFICIAL ELEMENT DIRECTORIES. THE LOCATIONS FOR RETRIEVING THE
REMAINING EXPERIMENTAL NDFD ELEMENTS /SEE TABLE 2/ REMAIN UNCHANGED.
