ATTENTION USERS OF THE MODEL OUTPUT STATISTICS /MOS/ GUIDANCE:
NOTE: THIS CHANGE IS SUBJECT TO OBTAINING A WAIVER FROM THE
TELECOMMUNICATIONS OPERATION CENTER MORATORIUM ON SYSTEM CHANGES.
ON TUESDAY... NOVEMBER 29 2005... 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 LATER:
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
