FROM:     Kathryn Gilbert

          Acting Director, Weather Prediction Center

 

Subject:  Use of Mixed-Case Text/95 ASCII Character Set in

          Selected NWS Weather Prediction Center Products

          Effective January 23, 2018

 

Effective Tuesday, January 23, 2018, at 1200 Coordinated

Universal Time (UTC), the National Centers for Environmental

Prediction (NCEP) Weather Prediction Center (WPC) will continue

its transition of text products to a mixed case text/expanded 

95 ASCII character set format. This phase of the transition will

apply to select products issued by WPC.

 

The following text products will be transitioned:

 

AWIPS ID     WMO ID        Product Name

 

PMDHMD       FXUS10 KWNH   Model Diagnostic Discussion

QPFERD       FOUS30 KWBC   Excessive Rainfall Discussion

PMDAK        FXAK02 KWNH   Alaska Extended Forecast Discussion

 

These products are in addition to the NCEP/WPC Short Range

Prognostic Discussion and Hawaii Discussion issued using the

mixed case/95 ASCII character set since April 2013. This

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 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.

 

Examples of Weather Prediction Center products already converted

to mixed case are online for sample formatting purposes:

http://www.wpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdhi

 

NWS Weather Prediction Center will notify users/partners of

future text product transitions to mixed case/expanded 95 ASCII

character set format via Service Change Notices with 30 days

lead time. These notices will include AWIPS product identifiers

and effective dates. 

 

If a Critical Weather Day prevents this change on January 23,

2018, the mixed case text format change will take effect on the

next available day.
