Experimental Snow Squall Warning
Proposed to Transition to Operational
Data Mining Tool
Outreach / Education
WFO: All WFO
Snow squalls are unique, extremely localized extreme weather events that can result in high impact to the public and commerce. Currently, hazard messages for these events are issued via generic Special Weather Statements (SPS) that are not enabled by Valid Time Event Code (VTEC). There is a long-standing need for a capability for the National Weather Service (NWS to be able to effectively disseminate this information to our partners who depend upon VTEC to recognize and parse our warning products for their customers.) In addition, the capability to define localized areas of threat (e.g., as is available for severe thunderstorms, tornadoes and flash floods through the use of NWS WarnGen software) would improve communication to the public via Wireless Emergency Alerts (WEA). The snow squall warning will be short-fused and polygon based enabling improved dissemination technique for maximum user distribution and effective Decision Support Services and will provide the critical, life-saving information for these short-term, highly localized, extreme hazardous events to our partners in the form that will allow them to recognize and parse the products and make them available to their customers.
