Note that the movement of individual thunderstorms was to the southeast. Data received at the RDA is processed and sent to NWS Louisville for further processing before final display of various radar products on AWIPS workstations for observation, forecast, and warning purposes. Animation of KLVX Doppler radar imagery on Aug 22, 2003. The RDA can be controlled by staff members at NWS Louisville. Such algorithms help identify trends that may support and provide guidance into severe weather warning decision process. Yet, the antenna transmits only a small fraction of the time, and "listens" for returned power from precipitation targets the rest of the time. NWS Doppler Radar (WSR-88D) Example Products NWS Doppler radar has various software algorithms which derive temporal and spatial trends in thunderstorms and other precipitating entities. The antenna is very sensitive and powerful, allowing forecasters to evaluate the structure, evolution, and motion of precipitation systems in great detail. The antenna also can sense movement of particles directed toward and away from the RDA (the "Doppler effect"), which allows calculation and assessment of winds and rotation in the atmosphere, especially within severe thunderstorms. Weather forecast and conditions for Louisville, Kentucky and surrounding areas. These targets are "hydrometeors," ranging from very small, non-precipitating particles (virga) to very large raindrops and hail from thunderstorms. The Current Radar map shows areas of current precipitation. Cleveland, OH Detroit, MI Dayton, OH Columbus. From the data, forecasters can quickly assess the full. is the official website for WHAS-TV, Channel 11, your trusted source for breaking news, weather and. For example, in volume coverage pattern (VCP) 212 (i.e., radars antenna scan strategy), the radar scans 14 elevation angles in about 4 minutes. Weather forecast and conditions for Louisville, Kentucky and surrounding areas. ![]() ![]() Inside the large white protective covering (radome) is a huge antenna that continuously rotates sending signals to and receiving signals from targets in the atmosphere. FL Tampa, FL Louisville, KY Raleigh / Durham, NC Pittsburgh, PA Washington, D.C. With NWS Doppler radar, all elevation angles (tilts) within a particular volume scan can be viewed very quickly using the 'All Tilts' product. After this time, the storm and its tornado moved east into Spencer County. Upper Left: Low-level base reflectivity image of a large supercell thunderstorm that produced a damaging tornado (in the hook echo area) in northeast Bullitt County (just south of Louisville) on May 28, 1996. This is the Radar Data Acquisition (RDA) of the NWS Louisville-Ft. NWS Doppler Radar (WSR-88D) Example Products.
