SUBJECT: Change in the Display of the National Centers for
         Environmental Prediction (NCEP) Weather Prediction
         Center (WPC) Short-Range Weather Charts and
         Termination of Associated Redbook Graphics
         effective September 1, 2015

Effective Tuesday, September 1, 2015, at 1200 Coordinated
Universal Time (UTC), the NCEP WPC will ONLY display the latest
National Digital Forecast Database (NDFD) weather forecast for
the weather portion of the short-range weather charts. This
change improves the detail of the product as well as consistency
between the NDFD and WPC information. NWS previously solicited
partner and user comments regarding this change:

http://www.nws.noaa.gov/os/notification/pns14wpc_short-
range_charts.htm

Currently, the weather portion of the short-term weather charts
allows partners and users to select either Color, Black and
White, Terrain Background or NDFD alternate displays:

Color:
http://www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php

Black and White:
http://www.wpc.ncep.noaa.gov/basicwx/basicwx_bw.php

Terrain Background:
http://www.wpc.ncep.noaa.gov/basicwx/basicwx_ter.php

NDFD:
http://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php

On and after September 1, 2015, the weather portion of the short-
term weather charts will only display the NDFD graphic. The other
display formats and selection buttons (Color, Black and White and
Terrain Background) will not be available.

Additionally, NWS will discontinue the legacy AWIPS Redbook
Graphic format of the short range weather product and show the
NDFD web display. NWS will terminate the following products:

PEIC61 KWBC
PEIE62 KWBC
PEIG63 KWBC
PEII64 KWBC

NDFD GRIB data serves as an alternative:
