Subject: Two Experimental Fire Weather Outlook Elements to be
Added to the National Digital Forecast Database
for CONUS Only Effective February 23, 2011
Effective Wednesday, February 23, 2011, at 1400 Coordinated
Universal Time (UTC), two Fire Weather Outlook elements will be
added to the National Digital Forecast Database (NDFD) on an
experimental basis over the Conterminous United States (CONUS)
only. These elements are generated by the National Centers for
Environmental Predictions (NCEP) Storm Prediction Center (SPC)
in Norman, OK.
These two Fire Weather Outlook elements will be added to the
NDFD CONUS sector and to the 16 pre-defined NDFD CONUS
subsectors for the valid times shown:
- Fire Weather Critical and Extremely Critical Areas (Days 1-7)
- Fire Weather Critical Areas for Dry Thunderstorms (Days 1-3)
More details regarding these new elements are available in the
Product Description Document (PDD) in the online catalog of
experimental NWS products and services.
http://products.weather.gov/detaile.php?selrow=416
With this implementation, these forecasts will be available from
NDFD in the standard methods:
- GRIdded Binary version 2 (GRIB2) files via Hypertext Transfer
Protocol (HTTP) and File Transfer Protocol (FTP)
- eXtensible Markup Language (XML) via Simple Object Access
Protocol (SOAP)
- Graphics via web browser
Users who pull NDFD elements in GRIB2 format, either via the
internet or via the Family of Services (FOS) server access
service, may need to update their procedures and/or scripts in
order to access these new elements.
For customers who key on the World Meteorological Organization
(WMO) super heading to access NDFD elements, the list of super
headings for these experimental elements is online at:
http://www.weather.gov/datamgmt/doc/spc.html
Customers who use the NDFD in XML via web service or the online
graphical NDFD images can use the same methods they currently
use to acquire these new experimental elements. The Fire
Weather Outlook NDFD graphics will be labeled experimental.
More information about accessing these new elements using all of
the standard NDFD access methods is available online at:
http://www.weather.gov/ndfd/spc_firewx.htm
Information on accessing and using NDFD elements is online at:
http://ndfd.weather.gov/techincal.htm
If February 23, 2011, is declared a critical weather day, this
implementation may be postponed. In that case, users will be
notified of that decision via an updated Technical
Implementation Notice as far in advance as possible.
Comments and feedback on the experimental Fire Weather Outlook
NDFD elements will be accepted through June 3, 2011. Links to
online surveys for NDFD customers are:
GRIB2 users:

Users OF XML SOAP service:

NDFD online graphics:

These new Fire Weather Outlook elements will remain experimental
until NWS assesses feedback and completes a technical analysis.
At that time, the NWS will determine whether to move these
experimental elements to operational status, discontinue them,
or revise and retain them as experimental elements.
