Subject:  Use of mixed-case text/95 ASCII character set and

          removal of coded Isohyet Points in the Quantitative

          Precipitation Forecast Discussion effective

          February 26, 2018

 

Effective Monday, February 26, 2018, at 1200 Coordinated

Universal Time (UTC), the National Centers for Environmental

Prediction (NCEP) Weather Prediction Center (WPC) will

transition the Quantitative Precipitation Forecast (QPF)

discussion to a mixed case text/expanded 95 ASCII character
set format.

 

In addition, WPC will discontinue the coded isohyet points which

represent the vertices of the forecast accumulation contours:

.01 inch, .25 inch, etc. These points are currently appended to

the end of the discussion text. The contouring information will

remain available in gridded and GIS formats elsewhere on the WPC

website.  GIS formatted data is available at

 

http://www.wpc.ncep.noaa.gov/kml/kmlproducts.php.

 

The following text product will be modified:

 

AWIPS ID    WMO ID           Product Name

-------     ------           ------------

QPFPFD      FXUS04 KWBC      Quantitative Precipitation Forecast

                             Discussion     

 

Expansion in the number of available mixed-case text products is

a continuation of the NWS transition to the use of mixed-case

letters. Use of mixed-case letters in text products will make

them easier to read and allow users to click on links directly

rather than converting them to lower or mixed case. Partners and

users of WPC text products should modify their systems to

accommodate mixed case and the expanded character set.

 

If a Critical Weather Day (CWD) prevents this change on February

26, 2018, the product format change will take effect on the next

non-CWD day.
