Louisville doppler weather radar12/8/2023 is the official website for WHAS-TV, Channel 11, your trusted source for breaking news, weather. The heaviest rainfall (red and orange colors) often display as an "S" shape or line echo wave pattern in organized, severe bow echoes. Weather forecast and conditions for Louisville, Kentucky and surrounding areas. Such vortices also concentrate a narrow swath of the most intense damage within the overall area of damage along the bow apex. Tornadoes can spin-up rapidly along and just north of the bow apex associated with small-scale mesovortices. The WEC often denotes the location of a channeled axis of higher speed winds called a rear inflow jet (RIJ) that can be responsible for producing wind damage along the leading gust front of the bow echo. Damaging straight-line winds occurred along the bow apex (labeled), which often is positioned on the leading edge of a weak echo channel (WEC labeled). Lower Center: Squall line (quasi-linear convective system QLCS) and embedded intense bow echo across north-central Kentucky on May 14, 1995. Weather forecast and conditions for Louisville, Kentucky and surrounding areas. Upper Center: Low-level base reflectivity image of a supercell thunderstorm that produced a damaging tornado (in the hook echo area) in Leitchfield (Grayson County), Kentucky on May 23, 2000. A derived product from NWS Doppler radar is Enhanced Echo Tops. The Current Radar map shows areas of current precipitation. This image corresponds to the reflectivity image in the upper left corner. This inflow funneled into the hook echo area and increased the strength of the low-level mesocyclone resulting in generation and maintenance of the tornado. NWS Doppler radar shows the location, intensity, and movement of precipitation, ranging from light snow flurries to very heavy rain and large hail. Note the enhanced storm-relative inflow (area of light green color) in extreme northeast Bullitt and western Spencer Counties, along the forward flank downdraft boundary. Lower Left: Low-level storm-relative velocity image of a mesocyclone (red outbound-green inbound couplet radar located to the west/left of the area shown) in northeast Bullitt County (just southeast of Louisville) that produced a damaging tornado on May 28, 1996. DVIL is useful to identify storms containing hail and a large liquid. DVIL is a vertical integration of reflectivity values within the full depth of a thunderstorm, with values converted to equivalent liquid water. This is an example of the Digital Vertically Integrated Liquid (DVIL) derived product. After this time, the storm and its tornado moved east into Spencer County. NWS Doppler Radar (WSR-88D) Example Products. 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.
