Subject:  Transition from Experimental to Operational Status of
          the Wind-Hail Tag Line for NWS Central Region Severe
          Thunderstorm Warnings: Effective November 15 2010

Effective Monday, November 15, 2010, NWS Weather Forecast
Offices (WFOs) in the NWS Central Region (CR) will transition a
service enhancement associated with severe thunderstorm warnings
from experimental to operational status. The enhancement is the
concise coded tag line identifying maximum forecast wind gusts
and hail size at the end of severe thunderstorm warnings (SVR)
and associated follow-up statements (SVS).

Inclusion of this information at the end of these products
represents an effort to respond to requests from partners in the
emergency management community and several societal impacts
groups. One specific application concerns the use of this
information to activate emergency alert sirens when conditions
exceed user-defined thresholds, a decision normally reserved for
tornado events.

The tag line makes easily accessible the information necessary
to reach such a decision. In addition, it facilitates the use of
parsing software to automate alerting functions whether by
government officials or private sector vendors.

Feedback during the experimental test period was so
overwhelmingly positive that the NWS CRH decided to make this
change a permanent and official part of severe thunderstorm
warnings issued from NWS CR WFOs. A map showing all CR WFOs is
available online at:

http://www.weather.gov/os/notification/resources/cr_wfos.pdf

A more detailed description of the coded tag line, including
format and examples, can be found in the Service Description
Document (SDD) at:
