The image shows a reflectivity cross-section of a supercell thunderstorm on April 7, 2006 from the NWS Louisville Doppler radar. The storm is over 40,000 feet tall. It has a large core of very heavy rain and hail (red and pink colors) within it. A bounded weak echo region (BWER), which denotes the location of the storm's rotating updraft (mesocyclone), is evident. The anvil of the storm is located to the right of the main updraft core aloft, where lighter precipitation and ice crystals are located. A much weaker, smaller thunderstorm is located just to the left of the supercell.
