SUBJECT:   Use of Mixed Case Letters in Area Forecast
           Discussion, Regional Weather Summary and Local
           Public Information Statement Products at Select
           Weather Forecast Offices Effective on or About
           October 4 2011
 
Effective on or about Tuesday, October 4, 2011, select NWS 
Weather Forecast Offices (WFOs) will begin issuing Area Forecast 
Discussion (AFD), Regional Weather Summary (RWS) and local 
Public Information Statement (PNS) products using upper and 
lowercase alphabetic letters and an expanded punctuation and 
character set (Table 1). This change is based on requests 
from many NWS partners and users.  The NWS first began seeking 
comments regarding mixed case text products in May 2010:

As part of a risk-reduction effort using a national,

non-operational product, NWS has been issuing National PNS

products using mixed case letters and the expanded

punctuation/character set since August 2010:

 

  http://www.weather.gov/os/notification/scn10-28mixed_case.txt

 

NWS partners and users of these WFO text products are encouraged 
to comment regarding this next step in the risk reduction effort.  
User feedback will help the NWS better plan the eventual 
transition of all NWS text products to mixed case and the expanded 
character set. Please provide comments by September 19, 2011, at:
 
 http://www.weather.gov/survey/nws-survey.php?code=mixed-case
 
Use of mixed case letters in text products will make them easier 
to read and allow users to click on internet links directly rather 
than converting them to lowercase or mixed case.  Additional 
punctuation and other characters that are part of the international 
reference Alphabet no. 5 will also be included as appropriate.

If this next phase of our risk reduction effort is implemented, 
partners and users will have the opportunity to further identify 
and correct any anomalous behavior of their systems and their 
customer’s systems that may be caused by mixed case and the 
expanded punctuation/character set in these WFO text products.
 
These products will continue to be issued using mixed case letters 
until each participating WFO transitions from AWIPS I to AWIPS II.  
Mixed case letters and the expanded punctuation/ character set for 
text products may not be supported in the initial AWIPS II software 
build. The NWS is working to minimize the impact of this transition 
on NWS users and will issue additional notices and statements as 
updated user information is available.  Partners and users should 
be aware these products may revert back to using all uppercase 
letters at the end of this phase of the risk reduction effort.
