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 Program’s 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
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:
