The 33rd Annual Meeting of the National Weather Association is upon us, literally and figuratively. The excitement is building at NWA World Headquarters and apparently for many of you as evidenced by the record number of submitted abstracts. NWA Executive Director Steve Harned tells me all available rooms at the Galt House were sold out in anticipation of our October gathering. The vision I offered nine months ago of an annual meeting designed to improve the future of operational forecasting through discussion and analysis of historical weather events is a reality thanks to the Herculean efforts of the Annual Program Committee chaired by John Gordon (NWS MIC in Louisville). -
Bragg Scatter Detection by the WSR-88D

ICE Radar Operations Center, National Weather Service, Norman, Oklahoma, and 557th Weather Wing, Offutt Air Force Base, Nebraska JEFFREY G. CUNNINGHAM 557th Weather Wing, Offutt Air Force Base, Nebraska (Manuscript received 25 January 2016, in final form 6 December 2016) ABSTRACT Clear-air Bragg scatter (CABS) is a refractivity gradient return generated by turbulent eddies that oper- ational Weather Surveillance Radar-1988 Doppler (WSR-88D) systems can detect. The randomly oriented nature of the eddies results in a differential reflectivity (ZDR) value near 0 dB, and thus CABS can be used as an assessment of ZDR calibration in the absence of excessive contamination from precipitation or biota. An automated algorithm to estimate ZDR bias from CABS was developed by the Radar Operations Center and can be used to assess the calibration quality of the dual-polarized WSR-88D fleet. This technique supplements existing ZDR bias assessment tools, especially the use of other external targets, such as light rain and dry snow. The estimates of ZDR bias from CABS using a 1700–1900 UTC time window were compared to estimates from the light rain and dry snow methods. -

INTRODUCTION related to the generation of supercooled liquid water (Hogan et al. 2002), 4) regions The classification of cold-season of high ZDR and KDP that are believed to be precipitation type at the surface is associated with dendritic growth and/or ice complicated by the broad range of crystal generation (Moisseev et al. 2008; precipitation types that might result from Andric et al. 2009; Kennedy and Rutledge processes that occur below the height of the 2011), and 5) an apparent tendency for ZDR radar’s lowest elevation sweep. For in the snow region to increase upon the example, a deep layer of subfreezing air onset of storm decay as regions of dry, near the surface might lead to either a aggregated snow (characterized by low ZDR) complete refreezing of drops (ice pellets) or are replaced by pristine ice crystals refreezing upon contact with the surface (characterized by high ZDR).

The partnership between the emergency managers and NWS not only 2 Digital Services continues strong, but continues to grow. With technology advancing at what seems the speed of light, availability of 3 Disaster products containing weather information has grown exponentially. Emergency Management managers are receiving volumes of information on the Internet, ranging from traditional text products to impact hazard graphics. 5 Dissemination In presentations and conversations here at NEMA, it is clear our partners need us to shift our emphasis from products to services. Our partners need 10 Fire Weather products that tie a plethora of information together into a package they can 11 Flood Awareness/ easily use. Emergency Operation Center (EOC) support requires impact services Hydrology that communicate climate, water and weather impacts from NWS offices, at the EOC or at the scene of the disaster. 12 Hurricane Several state emergency management directors commented that they have Preparedness plenty of information but lack the resources to better use that information. During numerous tornado and hurricane events, I have observed at EOCs and at 13 Outreach press conferences that NWS partners need to know impacts so lifesaving decisions can be made. -

Environmental Assessment - Relocation of the KLIX WSR-88D EXECUTIVE SUMMARY The National Weather Service (NWS) owns and operates the existing Weather Surveillance Radar, Model 1988 Doppler (WSR-88D) serving the New Orleans/Baton Rouge, LA area. The International Civil Aviation Organization designator for the radar is KLIX and the radar is located adjacent to the Weather Forecast Office (WFO) and Lower Mississippi River Forecast Center (RFC) at Slidell Airport in Slidell, St. Tammany Parish, LA. The radar site is about 30 miles northeast of downtown New Orleans, LA and about 78 miles east of downtown Baton Rouge, LA. The KLIX WSR-88D was commissioned in February 1995 and has been in continuous operation since 1995. It is one of 159 WSR-88Ds in the nationwide network. NWS plans to relocate the KLIX WSR-88D from its current site to a new location at Hammond North Shore Regional Airport (HDC) in Hammond, Tangipahoa Parish, LA (about 40 miles west-northwest of the WSR-88D’s existing location).
