Product Name:		Enhanced Product- Use of 1 inch Diameter Hail as a Criterion for Severe Thunderstorm Warnings in NWS Central Region
Geographical Scope:		Regional
Description:		The Central Region Severe Thunderstorm Warning (CR SVR) is an alphanumeric product providing short-fused warning in¬formation on hazardous conditions associated with thunderstorms which are expected to pose a threat to life and/or real property. This product is prepared by each National Weather Service (NWS) Weather Forecast Office (WFO) for their County Warning Area (CWA) of responsibility. Traditionally the SVR has been based on expectation of winds gusting to 58 mph or greater and/or hail of ¾ inch diameter or greater. In the Central Region, the minimum hail criterion is increased to one (1) inch in diameter. This change is motivated by research indicating significant damage does not occur until hail size reaches 1 inch in diameter, and in response to requests by core partners in emergency management and the media
