Subject: Discontinuance of the Experimental Second
         Generation National Convective Weather Forecast
         (NCWF-2) Effective June 16, 2011.

Effective Thursday June 16, 2011, at 0000 Coordinated Universal
Time (UTC), the NWS Aviation Weather Center will discontinue
production and dissemination of the experimental second
generation National Convective Weather Forecast (NCWF-2). The
current operational first generation National Convective Weather
Forecast (NCWF) product will continue to be available.

NCWF-2 is a probabilistic convective forecast developed through
the Federal Aviation Administration Aviation Weather Research
Programs Convective Weather Product Development Team. NCWF-2 is
currently available only via a direct feed from the Aviation
Weather Center in GRIB1 format using the following experimental
headers:

  ZDA98 KKCI
  ZDB98 KKCI
  ZDC98 KKCI
  ZDD98 KKCI
  ZUZA98 KKCI
  ZDIA98 KKCI
  ZMZA98 KKCI

And in BUFR format under JSAT98 KKCI.

Over the past several years, NCWF-2 has been considered for
transition from experimental to operational status. As part of
this transition process, detailed objective assessments of the
forecast quality and performance have been completed. Results of
the assessments indicated insufficient reliability and
resolution for operational implementation.

Since there are no plans to modify or improve NCWF-2 to achieve
operational suitability, and the hardware and software
technologies supporting the production of NCWF-2 are becoming
obsolete, NWS will discontinue the NCWF-2.

If you have any questions about this change, please contact:
