Subj:   termination of FOUS22 KWBC                    
I sent the following message on AFOS, NWWS, FAA/WMSC, FOS/Domestic Data 
Service, FOS/International Data Service, Honolulu, Alaska Region (via WMSC), 
and Montreal AES.
 
THIS PRODUCT, FOUS22 KWBC, IS NOT DISTRIBUTED ON AFOS, NOR IS IT SENT TO 
PACIFIC REGION.  IT DOES GO TO FAA, BUT THEY PROBABLY DON'T SEND IT TO ALSKA 
REGION, BECAUSE IT ONLY CONTAINS GUIDANCE FOR THE CONUS.  (GARY - PERHAPS JIM
JONES COULD CHECK ON THIS FOR YOU.  [HE'S ALWAYS SENDING ME STUFF TO DO.])
 
THEREFORE, I AM SENDING THIS MESSAGE TO ALL OF YOU NWS TYPES ONLY FOR YOUR 
INFORMATION, IN CASE YOU GET ANY QUESTIONS.
 
As for you Linda, the FOUS22 KWBC product IS sent on the FOS/Domestic Data 
Service, but I'm not sure if UNIDATA picks it up or not.  Your users may or 
may not be affected.  If they are, as stated in the message, we suggest they 
use FOUS14 KWBC (the NGM MOS guidance) as a replacement for the FOUS22 KWBC.
 
If I've confused anybody, give me a call.
 
As I said in the message, Mary Robinson and I will be sending all of you more 
info on the phase-out of the LFM and implementation of the Eta model on or 
about June 1, 1993 in mid-April.  It will include a product-by-product status 
of each product currently being generated from the LFM.  Stay tuned.

NATIONAL WEATHER SERVICE HEADQUARTERS
200 PM EST MON MAR 29 1993
 
TO:               USERS OF FOUS22 KWBC MESSAGE (FAA CIRCUITS,
                  DOMESTIC DATA SUBSCRIBERS, OFFUTT AFB, ISPAN)
 
FROM:             MARY M. GLACKIN
                  CHIEF, SERVICES DEVELOPMENT BRANCH
 
SUBJECT:          DISCONTINUATION OF FOUS22 KWBC MESSAGE
 
(INFORMATION FOR THIS ANNOUNCEMENT HAS BEEN PROVIDED BY
MARY ROBINSON OF THE OFFICE OF METEOROLOGY AND PAUL DALLAVALLE
OF THE TECHNIQUES DEVELOPMENT LABORATORY)
 
Effective April 28, 1993, the National Weather Service (NWS) will
terminate production of the FOUS22 KWBC bulletins that are now
being transmitted twice a day at approximately 1400 UTC and
0200 UTC.  The FOUS22 KWBC bulletins contain objective Model
Output Statistics (MOS) temperature (Mx/Mn) and precipitation
(PoP/PoF) forecasts for selected cities, based on the
Limited-area Fine-mesh Model (LFM).  This change results from the
upcoming phase-out of the LFM model for the contiguous U.S.,
effective on or about June 1, 1993.  
 
NOTE:  These products are not sent on the NWS' AFOS network, so
this change does not affect NWS AFOS users.
 
Users of the FOUS22 KWBC bulletin are referred to the FOUS14 KWBC
products as a suggested replacement for this type of objective
forecast guidance.  The FOUS14 KWBC bulletins are transmitted at
approximately 1530 UTC and 0330 UTC.  FOUS14 KWBC bulletins
contain MOS forecasts based on a different numerical model, the
Nested Grid model (NGM), for not only temperature and
precipitation, but other elements such as clouds, wind speed and
direction, thunderstorm probability, ceiling height forecasts,
precipitation type, etc.
 
Information on the interpretation of the FOUS14 KWBC bulletin may
be obtained by requesting a copy of Technical Procedures Bulletin
(TPB) No. 408: NGM-Based MOS Guidance - The FOUS14/FWC Message. 
You may call (301) 713-0462 to get a copy of this bulletin.  If
you are a TPB subscriber, you should have already received this
TPB.
 
If you need further information on the NGM-based MOS guidance,
please call Paul Dallavalle of the Techniques Development
Laboratory at (301) 763-8151, or write to him at:
 
NOAA/National Weather Service
Techniques Development Laboratory, W/OSD21
5200 Auth Road, Rm. 706
Camp Springs, MD  20746 
 
More information about the phase-out of the LFM model for the
contiguous U.S. and the status of other LFM-based products will
be forthcoming from the Office of Meteorology, both mailed
directly to users, and via future National Technical Information
Messages.
 
If you have any questions about the phase-out of the LFM for the
contiguous U.S., call Mary Robinson or Chris Alex of the Office
of Meteorology at (301)-713-0462.
